1-7 CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their job when you’re r eclined like this. The shoulder belt can’t do its job. In a crash, you could go into it, receiving neck or other injuries.
1-8 T o raise or lower a head restraint, pull up on the head restraint or push the head restraint down. The head restraints tilt forward also. T o tilt a head restraint forward, grab the top of the restraint and pull it toward you until you hear a click.
1-9 T o fold the rear seat, do the following: 1. Insert the two safety belt buckles into the pockets on the driver ’ s side seatback and place the passenger ’ s side seat belt through the loop located near the armrest before folding the rear seat.
1-10 Third Row Single Seat (If Equipped) Folding the Seatback CAUTION: If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked.
1-1 1 Tilting the Seat CAUTION: If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. 1. Fold the seatbacks forward using the instructions listed previously .
1-12 Returning the Seat to an Upright Position T o return the seat to an upright position, do the following: 1. Pull the lever labeled 3 toward you. 2. While still holding the lever 3 toward you, grasp the top of the seat and pull it toward you slightly .
1-13 3. T o unlatch the rear of the seat from the floor , pull up on the release lever labeled 2, located at the rear of the seat, and lift the rear of the seat up off of the floor . 4. Squeeze the release handle while pulling the seat out. 5. While holding the rear of the seat up, roll the seat out of the vehicle.
1-14 Replacing the Third Row Single Seat CAUTION: If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. CAUTION: A seat that isn’t locked into place properly can move around in a collision or sudden stop.
1-15 Entering or Exiting the Third Row Seat CAUTION: If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there.
1-16 Heated Rear Seats (Second Row) (If Equipped) The controls are located on the back of the center console. The ignition must be in RUN for this feature to operate. T o activate the heated seats, press the button to cycle through the high, medium and low settings.
1-17 CAUTION: It is extremely danger ous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas ar e more likely to be seriously injur ed or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and safety belts.
1-18 Why Safety Belts W ork When you ride in or on anything, you go as fast as it goes. T ake the simplest vehicle. Suppose it’ s just a seat on wheels.
1-19 Get it up to speed. Then stop the vehicle. The rider doesn’t stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield .
1-20 or the instrument panel ... or the safety belts! W ith safety belts, you slow down as the vehicle does. Y ou get more time to stop. Y ou stop over more distance, and your strongest bones take the forces. That’ s why safety belts make such good sense.
1-21 Here Ar e Questions Many People Ask About Safety Belts -- and the Answers Q: W on’t I be trapped in the vehicle after an accident if I’m wearing a safety belt? A: Y ou could be -- whether you’re wearing a safety belt or not. But you can unbuckle a safety belt, even if you’re upside down.
1-22 How to W ear Safety Belts Properly Adults This part is only for people of adult size. Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see the part of this manual called “Children.
1-23 4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
1-24 Q: What’ s wrong with this? A: The shoulder belt is too loose. It won’t give nearly as much protection this way . CAUTION: Y ou can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury .
1-25 Q: What’ s wrong with this? A: The belt is buckled in the wrong place. CAUTION: Y ou can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones.
1-26 Q: What’ s wrong with this? A: The belt is over an armrest. CAUTION: Y ou can be seriously injured if your belt goes over an armrest like this. The belt would be much too high.
1-27 Q: What’ s wrong with this? A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. CAUTION: Y ou can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury .
1-28 Q: What’ s wrong with this? A: The belt is twisted across the body . CAUTION: Y ou can be seriously injured by a twisted belt. In a crash, you wouldn’t have the full width of the belt to spread impact for ces. If a belt is twisted, make it straight so it can work properly , or ask your dealer to fix it.
1-29 T o unlatch the belt, just push the button on the buckle. The belt should go back out of the way . Before you close the door , be sure the belt is out of the way . If you slam the door on it, you can damage both the belt and your vehicle. Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women.
1-30 The best way to protect the fetus is to protect the mother . When a safety belt is worn properly , it’ s more likely that the fetus won’t be hurt in a crash. For pregnant women, as for anyone, the key to making safety belts effective is wearing them properly .
1-31 CAUTION: Air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, as you would be if you were leaning forward, it could seriously injure you. Safety belts help keep you in position before and during a crash.
1-32 How the Air Bag System W orks Where ar e the air bags? The driver ’ s air bag is in the middle of the steering wheel. The right front passenger ’ s air bag is in the instrument panel on the passenger ’ s side.
1-33 CAUTION: If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person causing sever e injury or even death.
1-34 How does an air bag restrain? In moderate to severe frontal or near - frontal collisions, even belted occupants can contact the steering wheel or the instrument panel.
1-35 In many crashes severe enough to inflate an air bag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the right front passenger air bag. Air bags are designed to inflate only once. After they inflate, you’ll need some new parts for your air bag system.
1-36 Air Bag Off Switch Y our vehicle has a switch on the instrument panel that you can use to turn off the right front passenger’ s air bag. United States Canada This switch should only be turned t.
1-37 Infant. An infant (less than 1 year old) must ride in the fr ont seat because: my vehicle has no r ear seat; my vehicle has a r ear seat too small to accommodate a r ear - facing infant seat; or .
1-38 Medical Condition. A passenger has a medical condition which, accor ding to his or her physician: causes the passenger air bag to pose a special risk for the passenger; and makes the potential ha.
1-39 Canada T o turn off the right front passenger ’ s air bag, insert your ignition key into the switch, push in, and move the switch to the off position. The AIR BAG OFF light will come on to let you know that the right front passenger ’ s air bag is off.
1-40 United States Canada T o turn the right front passenger ’ s air bag on again, insert your ignition key into the switch, push in, and move the switch to the on position.
1-41 Servicing Y our Air Bag-Equipped V ehicle Air bags affect how your vehicle should be serviced. There are parts of the air bag system in several places around your vehicle. Y ou don’t want the system to inflate while someone is working on your vehicle.
1-42 Rear Seat Passengers It’ s very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who aren’t safety belted can be thrown out of the vehicle in a crash.
1-43 2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. When the shoulder belt is pulled out all the way , it will lock. If it does, let it go back all the way and start again. If the belt is not long enough, see “Safety Belt Extender” at the end of this section.
1-44 The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen.
1-45 Rear Safety Belt Comfort Guides for Children and Small Adults Rear shoulder belt comfort guides will provide added safety belt comfort for older children who have outgrown booster seats and for small adults. When installed on a shoulder belt, the comfort guide better positions the belt away from the neck and head.
1-46 Third Row Seat For the third row , remove the guide from its storage clip on the side of the seatback. 2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide. 3. Be sure that the belt is not twisted and it lies flat.
1-47 Second Row Seat Third Row Seat 4. Buckle, position and release the safety belt as described in “Rear Seat Outside Passenger Positions” earlier in this section. Make sure that the shoulder belt crosses the shoulder . T o remove and store the comfort guides, squeeze the belt edges together so that you can take them out of the guides.
1-48 Center Passenger Position Lap Belt When you sit in the center seating position, you have a lap safety belt, which has no retractor . T o make the belt longer , tilt the latch plate and pull it along the belt.
1-49 T o make the belt shorter , pull its free end as shown until the belt is snug. Buckle, position and release it the same way as the lap part of a lap - shoulder belt. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section.
1-50 CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much -- until a crash. During a crash a baby will become so heavy it is not possible to hold it. CAUTION: (Continued) CAUTION: (Continued) For example, in a crash at only 25 mph (40 km/h), a 12 - lb.
1-51 CAUTION: Children who ar e up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap - shoulder belts offer outstanding protection for adults and older children, but not for young childr en and infants.
1-52 CAUTION: Newborn infants need complete support, including support for the head and neck. This is necessary because a newborn infant’ s neck is weak and its head weighs so much compared with the rest of its body .
1-53 Restraint Systems for Children An infant car bed (A), a special bed made for use in a motor vehicle, is an infant restraint system designed to restrain or position a child on a continuous flat surface. Make sure that the infant’ s head rests toward the center of the vehicle.
1-54 A forward - facing child seat (C - E) provides restraint for the child’ s body with the harness and also sometimes with surfaces such as T - shaped or shelf - like shields. A booster seat (F - G) is a child restraint designed to improve the fit of the vehicle’ s safety belt system.
1-55 Q: How do child restraints work? A: A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built - in child restraint system is a permanent part of the motor vehicle. An add - on child restraint system is a portable one, which is purchased by the vehicle’ s owner .
1-56 Where to Put the Restraint Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. General Motors, therefore, recommends that child restrai.
1-57 T op Strap Some child restraints have a top strap, or “top tether .” It can help restrain the child restraint during a collision. For it to work, a top strap must be properly anchored to the vehicle. Some top strap - equipped child restraints are designed for use with or without the top strap being anchored.
1-58 Anchor the top strap to one of the following anchor points. Be sure to use an anchor point located on the same side of the vehicle as the seating position where the child restraint will be placed. Raise the head restraint and route the top strap under it.
1-59 Third Row Seat Lower Anchorages and T op T ethers for Children (LA TCH System) Y our vehicle has the LA TCH system. Y ou’ll find anchors (A) in the outboard positions for the second row seats where the seatback meets the seat cushion.
1-60 In order to use the system, you need either a forward - facing child restraint that has attaching points (B) at its base and a top tether anchor (C), or a rear - facing child restraint that has attaching points (B), as shown here. W ith this system, use the LA TCH system instead of the vehicle’ s safety belts to secure a child restraint.
1-61 CAUTION: If a LA TCH - type child restraint isn’t attached to its anchorage points, the restraint won’t be able to protect a child sitting ther e.
1-62 Securing a Child Restraint in a Rear Outside Seat Position If your child restraint is equipped with the LA TCH system, see “Lower Anchorages and T op T ethers for Children (LA TCH)” in the Index. Y ou’ll be using the lap - shoulder belt. See the earlier part about the top strap if the child restraint has one.
1-63 3. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.
1-64 5. T o tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward - facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt.
1-65 Securing a Child Restraint in the Center Rear Seat Position Y ou’ll be using the lap belt. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say . See the earlier part about the top strap if the child restraint has one.
1-66 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. T o tighten the belt, pull its free end while you push down on the child restraint.
1-67 Securing a Child Restraint in the Right Front Seat Position If your child restraint is equipped with the LA TCH system, see “Lower Anchorages and T op T ethers for Children (LA TCH)” in the Index. Y our vehicle has a right front passenger air bag.
1-68 United States Canada.
1-69 CAUTION: A child in a rear - facing child restraint can be seriously injur ed or killed if the right front passenger’ s air bag inflates. This is because the back of the rear - facing child restraint would be very close to the inflating air bag.
1-70 Y ou’ll be using the lap - shoulder belt. See the earlier part about the top strap if the child restraint has one. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say .
1-71 5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 6. T o tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint.
1-72 Older Children Older children who have outgrown booster seats should wear the vehicle’ s safety belts. If you have the choice, a child should sit next to a window so the child can wear a lap - shoulder belt and get the additional restraint a shoulder belt can provide.
1-73 CAUTION: Never do this. Here two childr en are wearing the same belt. The belt can’t properly spr ead the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time.
1-74 CAUTION: Never do this. Here a child is sitting in a seat that has a lap - shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way , in a crash the child might slide under the belt. The belt’ s force would then be applied right on the child’ s abdomen.
1-75 Safety Belt Extender If the vehicle’ s safety belt will fasten around you, you should use it. But if a safety belt isn’t long enough to fasten, your dealer will order you an extender . It’ s free. When you go in to order it, take the heaviest coat you will wear , so the extender will be long enough for you.
1-76 Replacing Restraint System Parts After a Crash CAUTION: A crash can damage the restraint systems in your vehicle. A damaged restraint system may not properly pr otect the person using it, resulting in serious injury or even death in a crash.
2- 2-1 Section 2 Featur es and Controls Here you can learn about the many standard and optional features on your vehicle, and information on starting, shifting and braking. Also explained are the instrument panel and the warning systems that tell you if everything is working properly -- and what to do if you have a problem.
2-2 Windows CAUTION: Leaving childr en in a vehicle with the windows closed is dangerous. A child can be over come by the extreme heat and can suffer permanent injuries or even death from heat str oke. Never leave a child alone in a vehicle, especially with the windows closed in warm or hot weather .
2-3 Power Windows The controls for the power windows are located on the armrest on each of the side doors. The switches operate the windows when the ignition is in RUN, ACCESSOR Y or when Retained Accessory Power (RAP) is active. See “Retained Accessory Power” in the Index.
2-4 Keys CAUTION: Leaving childr en in a vehicle with the ignition key is dangerous for many r easons. A child or others could be badly injured or even killed. They could operate the power windows or other controls or even make the vehicle move. Don’t leave the keys in a vehicle with children.
2-5 Y our vehicle has a double - sided key for the ignition and all door locks. If you ever lose a key , your dealer will be able to assist you with obtaining replacements. NOTICE: Y our vehicle has a number of new features that can help prevent theft.
2-6 Door Locks CAUTION: Unlocked doors can be dangerous. Passengers -- especially childr en -- can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle won’t open it. Y ou increase the chance of being thrown out of the vehicle in a crash if the doors aren’t locked.
2-7 Power Door Locks The power door lock switches are located on the driver ’ s and front passenger ’ s armrests. Press the lock symbol to lock all of the doors. If the delayed locking feature is on, the doors will not lock until they are all closed.

2-10 Delayed Locking When locking the doors with the power lock switch or the keyless entry transmitter and any of the doors or the liftgate is open, the delayed locking feature will delay locking the doors and tailgate until five seconds after the last door is closed.
2-1 1 2. T urn the lock counterclockwise with your ignition key to engage the safety lock. T urn the lock clockwise with your ignition key to disengage the safety lock.
2-12 Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment. At times you may notice a decrease in range.
2-13 (Lock): Pressing this button once will lock all of the doors. Pressing the button again within three seconds may cause the horn to chirp to confirm that the doors have locked. Y ou can choose different feedback options for each press of the lock button, such as having the vehicle’ s perimeter lamps flash and/or have the horn chirp.
2-14 Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about two years. Y ou can tell the battery is weak if the transmitter won’t work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it’ s probably time to change the battery .
2-15 Liftgate CAUTION: It can be dangerous to drive with the liftgate open because carbon monoxide (CO) gas can come into your vehicle. Y ou can’t see or smell CO.
2-16 Theft V ehicle theft is big business, especially in some cities. Although your vehicle has a number of theft - deterrent features, we know that nothing we put on it can make it impossible to steal.
2-17 Content Theft - Deterrent Y our vehicle is equipped with a content theft - deterrent alarm system. W ith this system, the security light will flash as you open the door if your ignition is off. This light reminds you to activate the theft - deterrent system.
2-18 Here’ s how to avoid setting off the alarm by accident: If you don’t want to activate the theft - deterrent system, the vehicle should be locked with the door key after the doors are closed. Always unlock a door with a key , or use the remote keyless entry transmitter .
2-19 Passlock Y our vehicle is equipped with the Passlock theft - deterrent system. Passlock is a passive theft - deterrent system. Passlock enables fuel if the ignition lock cylinder is turned with a valid key . If a correct key is not used or the ignition lock cylinder is tampered with, the fuel system is disabled and the vehicle will not start.
2-20 Ignition Positions W ith your key in the ignition switch you can turn it to four different positions. A (LOCK): This position locks your ignition and transmission. It’ s a theft - deterrent feature. Y ou will only be able to remove your key when the ignition is turned to LOCK.
2-21 Starting Y our Engine Move your shift lever to P ARK (P) or NEUTRAL (N). Y our engine won’t start in any other position -- that’ s a safety feature. T o restart when you’re already moving, use NEUTRAL (N) only . NOTICE: Don’t try to shift to P ARK (P) if your vehicle is moving.
2-22 When starting your engine in very cold weather (below 0 F or - 18 C), do this: 1. W ith your foot off the accelerator pedal, turn the ignition key to ST AR T and hold it there up to 15 seconds.
2-23 3. Plug it into a normal, grounded 1 10 - volt AC outlet. CAUTION: Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. Y ou could be seriously injured.

4- 4-1 Section 4 Y our Driving and the Road Here you’ll find information about driving on different kinds of roads and in varying weather conditions.
4-2 Defensive Driving The best advice anyone can give about driving is: Drive defensively . Please start with a very important safety device in your vehicle: Buckle up. See “Safety Belts” in the Index. Defensive driving really means “be ready for anything.
4-3 Drunken Driving Death and injury associated with drinking and driving is a national tragedy . It’ s the number one contributor to the highway death toll, claiming thousands of victims every year . Alcohol affects four things that anyone needs to drive a vehicle: Judgment Muscular Coordination V ision Attentiveness.
4-4 It’ s the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour , the person’ s BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level.
4-5 The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. “I’ll be careful” isn’t the right answer .
4-6 Control of a V ehicle Y ou have three systems that make your vehicle go where you want it to go. They are the brakes, the steering and the accelerator .
4-7 A void needless heavy braking. Some people drive in spurts -- heavy acceleration followed by heavy braking -- rather than keeping pace with traffic. This is a mistake. Y our brakes may not have time to cool between hard stops. Y our brakes will wear out much faster if you do a lot of heavy braking.
4-8 Let’ s say the road is wet and you’re driving safely . Suddenly , an animal jumps out in front of you. Y ou slam on the brakes and continue braking.
4-9 Remember: Anti - lock doesn’t change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you won’t have time to apply your brakes if that vehicle suddenly slows or stops.
4-10 T o enter this mode, press the TC2 button located on the instrument panel to the right of the steering wheel. TC2 only operates in the following transfer case modes: 4HI Lock 4LO Lock 4LO Lock and Differential Lock It will not operate in 4HI. If the TC2 button is pressed while in 4HI, the light will flash for about 15 seconds and then go out.
4-1 1 Steering Power Steering If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. Steering Tips Driving on Curves It’ s important to take curves at a reasonable speed.
4-12 Steering in Emergencies There are times when steering can be more effective than braking. For example, you come over a hill and find a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you.
4-13 Off - Road Recovery Y ou may find that your right wheels have dropped off the edge of a road onto the shoulder while you’re driving. If the level of the shoulder is only slightly below the pavement, recovery should be fairly easy .
4-14 Do not get too close to the vehicle you want to pass while you’re awaiting an opportunity . For one thing, following too closely reduces your area of vision, especially if you’re following a larger vehicle. Also, you won’t have adequate space if the vehicle ahead suddenly slows or stops.
4-15 Loss of Control Let’ s review what driving experts say about what happens when the three control systems (brakes, steering and acceleration) don’t have enough friction where the tires meet the road to do what the driver has asked. In any emergency , don’t give up.
4-16 Off - Road Driving Also, see “Anti - Lock Brakes” in the Index. Off - road driving can be great fun. But it does have some definite hazards. The greatest of these is the terrain itself. “Off - roading” means you’ve left the great North American road system behind.
4-17 Loading Y our V ehicle for Off-Road Driving There are some important things to remember about how to load your vehicle. The heaviest things should be on the load floor and forward of your rear axle.
4-18 Environmental Concerns Off - road driving can provide wholesome and satisfying recreation. However , it also raises environmental concerns. W e recognize these concerns and urge every off - roade.
4-19 High Mobility Characteristics The HUMMER H2 has a 12 inch (30.5 cm) running ground clearance (A) and a 9 inch (22.8 cm) axle to ground clearance (B) while maintaining a low silhouette and a low center of gravity . These characteristics are essential to safety in off - road operation.
4-20 The HUMMER H2 has an approach angle of 42 (A) and a departure angle of 37 (B). Design specifications required a minimum gradeability of 60% (31 ) slope, with the vehicle fully loaded, on high friction surfaces at 6 mph (9.
4-21 Also, specifications required that the HUMMER H2 be able to traverse a 40% (22 ) side slope at 6 mph (9.7 km/h) while fully loaded on high friction surfaces.
4-22 Brake and Throttle Modulation for Enhanced Mobility The use of this technique will give the driver the ability to traverse challenging obstacles with more confidence, safety and care to both the vehicle and the terrain. It allows the driver to gain control of the vehicle systems and place power and wheel torque where it is needed most.
4-23 For mounds, washouts, loose up - hill slopes, ditches, etc. When wheel spin occurs as the vehicle is moving, the driver may notice a slight shaking or shuddering of the vehicle. This is the indication that a loss of traction is occurring on this terrain.
4-24 Getting Familiar with Off-Road Driving It’ s a good idea to practice in an area that’ s safe and close to home before you go into the wilderness. Off - road driving does require some new and dif ferent driving skills. Here’ s what we mean. T une your senses to different kinds of signals.
4-25 Scanning the T errain Off - road driving can take you over many dif ferent kinds of terrain. Y ou need to be familiar with the terrain and its many different features. Here are some things to consider . Surface Conditions. Off - roading can take you over hard - packed dirt, gravel, rocks, grass, sand, mud, snow or ice.
4-26 Crossing Obstacles Appr oach Angle - a Key to Mobility . If you encounter a large dip in the terrain, do not enter straight on; enter at an angle (15 minimum approach (A), 75 maximum approach angle (B)). For very large dips, ditches or small washes, coast in, using the engine as a brake.
4-27 Log Cr ossing. Using the proper technique, the HUMMER H2 will cross logs up to 12 inches (30.5 cm) in diameter . Approach the log at approximately a 15 angle (A) with the transfer case in 4LO Lock and “walk” the HUMMER H2 over , one tire at a time.
4-28 Approaching a Hill When you approach a hill, you need to decide if it’ s one of those hills that’ s just too steep to climb, descend or cross. Steepness can be hard to judge. On a very small hill, for example, there may be a smooth, constant incline with only a small change in elevation where you can easily see all the way to the top.
4-29 Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps. Use a low gear and get a firm grip on the steering wheel. Get a smooth start up the hill and try to maintain your speed. Don’t use more power than you need, because you don’t want your wheels to start spinning or sliding.
4-30 Q: What should I do if my vehicle stalls, or is about to stall, and I can’t make it up the hill? A: If this happens, there are some things you should do, and there are some things you must not do. First, here’ s what you should do: Push the brake pedal to stop the vehicle and keep it from rolling backwards.
4-31 Q: Suppose, after stalling, I try to back down the hill and decide I just can’t do it. What should I do? A: Set the parking brake, put your transmission in P ARK (P) and turn off the engine. Leave the vehicle and go get some help. Exit on the uphill side and stay clear of the path the vehicle would take if it rolled downhill.
4-32 Driving Downhill When off - roading takes you downhill, you’ll want to consider a number of things: How steep is the downhill? W ill I be able to maintain vehicle control? What’ s the surface.
4-33 Q: Are ther e some things I should not do when driving down a hill? A: Y es! These are important because if you ignore them you could lose control and have a serious accident. When driving downhill, avoid turns that take you across the incline of the hill.
4-34 Driving Across an Incline Sooner or later , an off - road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: A hill that can be driven straight up or down may be too steep to drive across.
4-35 Q: What if I’m driving across an incline that’ s not too steep, but I hit some loose gravel and start to slide downhill. What should I do? A: If you feel your vehicle starting to slide sideways, turn downhill. This should help straighten out the vehicle and prevent the side slipping.
4-36 Driving in Mud, Sand, Snow or Ice When you drive in mud, snow or sand, your wheels won’t get good traction. Y ou can’t accelerate as quickly , turning is more difficult, and you’ll need longer braking distances. It’ s best to use a low gear when you’re in mud -- the deeper the mud, the lower the gear .
4-37 Driving in W ater Heavy rain can mean flash flooding, and flood waters demand extreme caution. Find out how deep the water is before you drive through it. If it’ s deep enough to cover your wheel hubs, axles or exhaust pipe, don’t try it -- you probably won’t get through.
4-38 After Off-Road Driving Remove any brush or debris that has collected on the underbody , chassis or under the hood. These accumulations can be a fire hazard. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking.
4-39 Here are some tips on night driving. Drive defensively . Don’t drink and drive. Adjust your inside rearview mirror to reduce the glare from headlamps behind you. Since you can’t see as well, you may need to slow down and keep more space between you and other vehicles.
4-40 Driving in Rain and on W et Roads Rain and wet roads can mean driving trouble. On a wet road, you can’t stop, accelerate or turn as well because your tire - to - road traction isn’t as good as on dry roads. And, if your tires don’t have much tread left, you’ll get even less traction.
4-41 Driving too fast through large water puddles or even going through some car washes can cause problems, too. The water may affect your brakes. T ry to avoid puddles. But if you can’t, try to slow down before you hit them. CAUTION: W et brakes can cause accidents.
