Fuel Econom y Driving 191 Driveline Combination Engine, transmission and final driv e must be selected in such a way that the engine can operate within the economic speed range at normal dri ving speed. This range is defined as where the engine makes the best use of the ener gy content of the diesel fuel.
192 Fuel Econom y Driving Gross V ehicle W eight The gross vehicle weight of a vehicle com- bination has a large impact on the rolling resistance. Accessories As a rule, accessories such as roof rack, ad- vertising signs, bug screens, e xposed air horns, etc.
Fuel Econom y Driving 193 Axles An axle out of alignment will increase rolling resistance. Regularly check the front wheel alignment and axles on both the trac- tor and trailer/semi-trailer . If they are correct, there will be less rolling resistance and, therefore, lower fuel consumption.
194 Fuel Econom y Driving External Environment Under unfav orable conditions, the external en vironment can hav e a negati v e effect on fuel consumption.
Fuel Econom y Driving 195 Driving Habits The way in which a vehicle is being driv en is the one factor which has the greatest in- fluence on fuel consumption.

Engine Start and Operation 197 Starting the Engine Star t Procedure NO TE! For cold weather starting, see page 202. These starting and operating procedures should be follo wed for all engines. For more detailed information about design and function on a non-V olvo engine, read the Operator’s Manual from the engine manu- facturer .
198 Engine Star t and Operation 1 Before starting the engine, perform the engine pre-trip inspection and daily maintenance checks in “Pre-Trip In- spection and Daily Maintenance” starting on page 28. 2 Make sure the parking brakes are en- gaged. 3 Place the transmission in neutral or depress the clutch pedal.
Engine Start and Operation 199 5 T urn the key on to the start position. Release key as soon as the engine has started. For the V olvo engine, the pre- heater can be engaged to help starting in cold temperatures.
200 Engine Star t and Operation Stopping the Engine Allow the engine to slow down and idle for 3 to 5 minutes before shutting it of f. This allows the turbo to slow do wn and the cooling system to dissipate the engine heat. Switch the engine off by turning the igni- tion key to the O , or OFF , position.
Engine Start and Operation 201 Ignition Switch The ignition switch is located on the right side of the steering column just under the steering wheel. Standard equipment is a normal ignition switch. A steering wheel lock is av ailable as an op- tion. When the key is remo ved it actuates a detente pin that prevents the steering shaft from turning.
202 Engine Star t and Operation Cold W eather Star t and Operation V olvo Engine Cold Star t NO TE! These cold start instructions are for V olvo engines only . For other engine makes, see the manufacturer’s handbook. Do not use ether or similar starting aids in a V olvo or any other engine with start help.

204 Engine Star t and Operation Ether Star t Do not use ether or similar starting aids in a V olvo or any other engine with start help. The V olvo engine is equipped with a preheater .
Engine Start and Operation 205 Cold Weather Operation If the engine is in good mechanical condi- tion and the necessary preparations are taken for cold weather operation, ordinary cold weather will not cause difficulty in starting or loss of efficienc y .
206 Engine Star t and Operation • During cold weather , giv e more atten- tion to the condition of the batteries. T est them frequently to ensure suffi- cient power for starting. A dead battery may freeze. • Fuel cloud point is the temperature at which wax crystals become visible, which is generally abov e the pour point of the fuel.
Engine Start and Operation 207 Oil Pan Heater (option) Oil pan heaters aid low temperature starting by improving oil flow to critical parts in the engine. This helps prev ent engine wear . They are similar to block heaters and are wired into the same plug as the engine coolant heater .
208 Engine Star t and Operation Winterfront V olvo Trucks North America, Inc. does not recommend the use of winterfronts, shutters or any other shield in front of the grille or radiator package under normal circum- stances. T oday’s electronically controlled engines are designed to operate in cold tempera- tures without a winterfront.
Engine Start and Operation 209 Engine Operation General Proper operation, driving techniques and maintenance are key factors in obtaining the maximum life and economy from a modern turbocharged diesel engine. This section has operational information about the components that make up the engine.
210 Engine Star t and Operation The operator should understand the operat- ing characteristics of the engine the vehicle is equipped with. Modern diesel engines hav e maximum torques at much lo wer en- gine speeds than in the past. As such, these engines are designed to perform satisfacto- rily at a lower speed.
Engine Start and Operation 211 Engine Shut-Down System Failure to take the necessary precautions when the INFO or STOP telltales are on, can ultimately result in automatic engine shut-down and the loss of po wer steering.
212 Engine Star t and Operation Engine Overspeed This vehicle is equipped with a diesel en- gine and should not be operated in an area with a concentration of hydrocarbon vapors (for example gasoline or diesel fuel fumes). Be especially cautious of low-lying or closed-in areas.
Engine Start and Operation 213 Idling All engines in the VHD models are elec- tronically gov erned engines. The idle speed is pre-programmed from the manufacturer . Low idle speed is adjustable within certain limits (for most engines between 600 to 750 r/min).
214 Engine Star t and Operation Low Idle Adjustment If the engine coolant temperature is abov e 122 F (50 C), the vehicle is stationary (en- gine running; accelerator released; parking brake on) and the PTO not engaged, the en- gine low idle speed can be adjusted with the use of the cruise control function.
Engine Start and Operation 215 Idle Shutdown Timer The idle shutdown timer can be pro- grammed to shut the engine down after a specific engine idling time. The program can not be changed by the operator b ut requires a special tool (Pro-Link) that con- nects to the engine electronic control unit.
216 Engine Star t and Operation Uphill Operation For best performance, allow engine speed to reach the bottom of the rated torque range before downshifting. Continue to downshift in this manner until a gear is reached that will maintain the desired speed.
Engine Start and Operation 217 High Altitude Operation Engines lose power when operated at high altitude because the air is too thin to allow burning as much fuel as at sea lev el. For naturally aspirated engines, this loss is about 3 percent per 1000 feet (300 m) in- crease in altitude abov e sea lev el.
218 Engine Star t and Operation Cruise Control Do not use the cruise control in heavy traffic, with ice/sno w on the road or dur- ing other unfav orable conditions. This may lead to a loss of vehicle control, causing a vehicle crash and can result in personal injury or death.
Engine Start and Operation 219 Disengaging The cruise control is disengaged if the brake or clutch pedal is depressed, or if the cruise control switch is set to OFF . If the ignition key is turned back to the acces- sories position (R), the cruise control system will automatically be disengaged.
220 Engine Star t and Operation Fuel T ank(s) T ank Cap Do not remov e the fuel tank cap near an open flame. Diesel fuel vapors are com- bustible and can cause an explosion or fire, resulting in sev ere personal injury or death. The fuel tank caps hav e a pressure and a thermal relief function built into the cap.
Engine Start and Operation 221 Fueling Air is always present inside the fuel tanks, entering mainly through the tank ventila- tion. W ith the air being heated up and cooled down, condensation is formed and water is mixed in the fuel. T o av oid con- densation when the vehicle is parked for longer periods, fill the tanks up to 95% of capacity .
222 Clutch and T ransmission Clutch General Before starting the engine, set the park- ing brakes and place the transmission in neutral. Failure to do so can result in un- expected v ehicle mov ement and can cause serious personal injury and death. Do not allow the clutch to slip excessi vely .
Brakes 223 Brakes Brake Saf ety Information Do not inspect or adjust parts or compo- nents in the brake system without setting the parking brake, placing the transmis- sion in neutral and securely chocking the wheels. If the vehicle is not secured to prev ent uncontrolled vehicle mov ement, it could roll and cause severe personal injury or death.
224 Brakes Do not release the parking brake or at- tempt to mov e the vehicle until brake air pressure in both circuits is at least 100 psi (690 kPa). Failure to follow this pro- cedure may lead to uncontrolled vehicle mov ement and cause sev ere personal in- jury or death.
Brakes 225 Both circuits are piped into a dual brake valv e, which simultaneously applies front and rear axle service brakes during each brake application. In the e vent of a failure in either one of the circuits, the other cir- cuit becomes the emergenc y circuit for applying the brakes.
226 Brakes Brake System Controls The air compressor , gov ernor , pressure reg- ulator valv e and reservoirs are control devices. Their function is to build up, maintain and control air pressure in the reservoirs. This is so that pressure is held constant between the minimum and maxi- mum range established for air brake operation.
Brakes 227 From the operator’s viewpoint, operating the foot brake valv e of a vehicle equipped with air brakes differs v ery little from the operation of a con ventionally braked vehi- cle.
228 Brakes 4 In making a stop or a slow-do wn, al- low the transmission to remain in gear with the throttle closed, disengaging the clutch only when engine idling speed is reached. 5 When parking the vehicle, place the transmission in neutral and set the parking brake before shutting do wn the engine.
Brakes 229 Parking Brake/T railer Supply V alves Trucks/T ractors may have two air control valv es on the instrument panel: • Trailer Supply (red octagonal knob) • System Park (yello w diamond knob) The two air control valv es are intercon- nected and interacting.
230 Brakes Parking Brake Release VHD models hav e engines equipped with engine electronic control units (EECU). These have two features that may impact the brake system. One is the anti-stall de- vice in the EECU which senses torque demand and automatically controls the en- gine to compensate and maintain speed.
Brakes 231 There is also an engine shut-down device in the EECU that shuts the engine down af- ter a pre-programmed time in order to sa ve fuel. This is activ ated when the yellow parking brake knob is pulled out. There- fore, some driv ers park and release the parking brakes using only the red knob to keep the engine running.
232 Brakes Spring Brake For Parking Nev er leav e the vehicle without being certain the parking brakes are set or that other precautions are taken to prev ent the vehicle from rolling.
Brakes 233 There are sev eral ways to determine if the parking brakes hav e been set. By pulling out the yellow knob: • An audible rush of air will be heard when the parking brake knob is pulled. The air exhausts from the park brake valv e itself and from the spring brake chambers on the rear axle(s).
234 Brakes T railer Brake Hand Control The trailer hand brake control is not a parking brake valv e and must not be used as one. This brake is not designed to hold the vehicle stationary . Failure to follow these instructions can result in the unintentional mov ement of the vehicle and may cause personal injury or death.
Brakes 235 The “121” Brake Standard This manual refers occasionally to “121” brakes. Although some operators belie ve “121” only applies to vehicles equipped with anti-lock devices, the “121” standard applies to all vehicles that are capable of on-highway operation.
236 Brakes Antilock Braking System (ABS) The vehicle has a standard brake system, equipped with an electronic speed monitor- ing and control system, Antilock Braking System (ABS). ABS monitors wheel speed continuously b ut is not in volv ed in control- ling the wheel speed unless there is an emergenc y .
Brakes 237 During emergenc y or reduced-traction stops, fully depress the foot brake pedal un- til the vehicle comes to a safe stop. DO NO T PUMP the brake pedal. W ith the brake pedal fully depressed, the ABS will control all wheels to provide steering con- trol and a reduced braking distance.
238 Brakes T raction Control System (TCS) (option) The Traction Control System (TCS) uses the same wheel sensors as the ABS to de- termine if one set of drive wheels is spinning much more rapidly than the wheel set on the other side.
Brakes 239 V ehicle Speed Retardation De vices When operating a tractor bobtail (with- out a trailer) or on slippery roads, the engine brake switch must be in the “ OFF ” position. Failure to follo w this instruction can result in loss of vehicle control and serious personal injury or death.
240 Brakes V olvo Exhaust Brake The exhaust brake is standard on the V olvo D12 engine. It is used to reduce wear on the brake linings. The exhaust brake is most effecti v e at high engine speeds (1500 to 2300 r/min). The exhaust brake is auto- matically disengaged if the engine speed drops to or below 1100 r/min.
Brakes 241 V olvo Engine Brake (option) The V olvo Engine Brake (VEB) has a higher braking effect than the exhaust brake. The engine brake is most effecti ve at high engine speeds (1500 to 2300 r/min). It is automatically disengaged if engine speed drops below 1100 r/min.
242 Brakes Jake-Brake Or C-Brake The Jake-Brake or C-Brake is optional equipment for Cummins, and Detroit en- gines. These engine brakes are similar in operation. Three power le vels are a vailable by engaging 2, 4, or 6 cylinders when brak- ing (for Cummins M11, only two power lev els are av ailable).
Brakes 243 T ransmission Retarder The Transmission Retarder is an option with Allison HD and MD transmissions. It is activ ated by an on/off switch in the aux- iliary panel and is controlled by a stalk switch mounted in front of the wiper switch. Y ou can set 6 different le v els with the stalk switch.
244 Electrical System Electrical System General Safety Guidelines W ARNING Failure to repair a malfunction in the electrical system can result in serious damage due to vehicle fire. Always let an experienced electrical technician perform repairs. Always determine the source of the fault; do not just treat the symptoms.
Electrical System 245 Charging System An alternator with an integrated re gulator is used to supply power to the vehicle electri- cal system. The charging system voltage should be checked periodically to prev ent ov ercharging or undercharging the batteries and to detect any voltage drop in the wiring.
246 Electrical System There may be three or four batteries in- stalled. Always make sure the batteries are fastened properly in the box. When disconnecting battery terminals, al- ways disconnect the main ground terminal first. When reconnecting, always connect the main ground terminal last.
Electrical System 247 Battery J ump Star ting and Charging T o access the batteries on a vehicle equipped with side fairings, open the fair- ing access cov er . On the second battery from the front there are special, longer posts installed to accept jumper cables.
248 Electrical System Charging the Batter y High voltage machines that are used for work on the vehicle can do damage to the electrical system, especially to its electronic components.
Electrical System 249 Electronic Components CA UTION Electronic circuits and components are designed to sense voltage dif ferences smaller than 1 volt. While static electric- ity is not normally dangerous to humans, it can seriously damage electronic cir- cuits and components.
250 Electrical System CA UTION If there are other ground cables con- nected to the battery (such as engine ECU, etc.), disconnect those ground ca- bles first, then remo ve the main battery ground cable. Electronic modules may be damaged when additional grounds are connected/disconnected without the main battery ground connected.
Electrical System 251 • Attach the welder ground cable as close to the weld area as possible (6 inches or less from the place being welded). • Do not connect the welder ground ca- ble to the EECU or its cooling plate.
252 Electrical System Battery Protection System (option) An electronic battery monitor (“Battery Lifeguard”) may be installed in the electri- cal center . This monitor will disconnect certain circuits if it senses that the battery voltage falls under a safe charging le vel.
Electrical System 253 Electrical Center W8000923 The electrical center is located in the mid- dle of the dash. All the relays and fuses in the cab are collected here.
254 Electrical System The fuses and relays are all accessible un- der the top cov er on the dash. W3002526 One type of fuse in the ne w electrical cen- ter are termed “mini-fuses” and require a puller tool to remov e from the fuse block. The puller tool is part of the Owner’s Pack- age.
Electrical System 255 P ower Studs On the passenger side of the dash are power studs for a CB hook-up. These studs are standard equipment. For a proper hook- up, use fork type connectors on the wires or use “banana” plugs. CA UTION If stripped wire ends are used, make sure there are no wire strands that can bridge between the studs.
256 P o wer Steering General The power steering consists of an inte- grated gear and hydraulic power c ylinder , and a power steering pump with fluid con- tainer . The pump, driv en by the engine, provides hydraulic pressure to the power steering. If the engine is not working, the steering is only manual.
P ower Steering 257 Periodically check the power steering fluid reservoir and keep it filled to the proper lev el with the recommended fluid. See the “ Operator’s Manual, Maintenance and En- gine ” for more information. There is also a filter inside the reservoir that needs to be changed every 12 months.
258 Axles and Wheels Axles Differential Loc ks The driv e axle(s) may be equipped with differential locks. The single driv e axle will only hav e a wheel differential lock. W ith tandem driv e axles, there could be both wheel differential locks and an inter-axle differential lock.
Axles and Wheels 259 Engaging the differential locks must always be done in the following way (see page 104 for switch location): 1 Depress the clutch pedal.
260 Axles and Wheels Auxiliary Lift Axle Before raising or lowering any of the auxiliary axles, be certain no one can be trapped by the axle mov ement. Failure to do so can result in a person being trapped between the wheel and the body , or between the wheel and the ground, resulting in serious personal injury or death.
Axles and Wheels 261 Wheels General Due to the size, equipment needed and the procedures used to change wheels, this should be done through the V olvo Truck dealer . By having an expert technician per- form this procedure, personal injury and property damage may be av oided.
262 Axles and Wheels Inflating Tires Always check inflation pressures when the tires are cool, using an accurate tire pres- sure gauge. Check the pressures at regular intervals. CA UTION Nev er bleed the air from hot tires. In- creased tire pressure measured in a hot tire is normal.
Axles and Wheels 263 Wheel Bearing Adjustment For reliable operation and adequate service life, the wheel bearings must be properly adjusted and checked during the service pe- riod. Loose wheel bearings could cause premature tire wear and possibly affect ve- hicle handling.
264 Fifth Wheel Instructions Fifth Wheel General Information The standard fifth wheel is manufactured by ASF . Other fifth wheels av ailable as op- tions are Holland and Fontaine. Things to think about with trailer hook-up: • Check the load distribution between axles.
Fifth Wheel Instructions 265 Saf ety Inf or mation Follo w the instructions on the advisory la- bels attached to the v arious manufacturers’ fifth wheels. An operator’s manual from the manufacturer is supplied with each fifth wheel and is provided in the Owner’s pack- age.
266 Fifth Wheel Instructions Locked — This is the position that the fifth wheel will be in with a trailer hooked up. In the locked position, the operating rod is retracted and the safety latch will freely swing back and forth. W9000180 Lockset — This is the position the fifth wheel is in when uncoupling the trailer .
Fifth Wheel Instructions 267 Fifth Wheel Slider (option) The fifth wheel comes standard with an air operational slider . T o remain within legal weight limits, this feature allows the driv er to distrib ute the load easily on the axles. The air operated slider takes the work out of adjusting the tractor for various trailer loads.
268 Fifth Wheel Instructions Unlocking the Fifth Wheel Always check out the entire fifth wheel equipment before attempting to couple to a trailer (ASF fifth wheel is shown): • If not lubricated properly , add grease to the top of the fifth wheel plate.
Fifth Wheel Instructions 269 When the shoulder of the operating rod is outside of the operating slot, raise the oper- ating rod handle to its maximum upward position. W9000242 Release the operating rod. The upper shoul- der of the operating rod should now be in contact with the plate casting above the op- erating slot.
270 Fifth Wheel Instructions T railer Coupling Pr ocedures This procedure cov ers vehicles with and without air suspension. Failure to properly couple the tractor and trailer can result in their separation, causing death and property damage.
Fifth Wheel Instructions 271 Make sure the mounting of the fifth wheel to the tractor frame is tight and in good condition. If using a sliding fifth wheel, make sure the slide locking plungers are fully engaged. W9000205 Chock the trailer wheels. Use two chocks (both on the front and rear of the wheel) on both sides of the trailer .

280 Fifth Wheel Instructions Operating the Fifth Wheel Slider W ARNING The trailer must be stopped and the trailer brakes locked, or damage to the tractor and/or trailer may result from un- controlled sliding of the fifth wheel. Stop the tractor and trailer in a straight line on lev el ground.
Fifth Wheel Instructions 281 Slowly dri v e the tractor forward or back- ward to position the fifth wheel. After sliding the fifth wheel to the desired position, engage the slide locking plungers by moving the cab switch to the “LOCK” position (press in the top part of the switch).
282 Emergency Inf ormation T owing Pr ocedure General CA UTION The driv eshaft must be remov ed before towing the v ehicle. Failure to remov e the driv eshaft may result in damage to the transmission. Remov e the driv e shaft from the rear axle before moving the vehicle, unless it only needs to be moved a small distance for safety reasons.
Emergency Inf ormation 283 W ARNING Do not tow a vehicle backwards when equipped with roof air fairings. The fair- ings act as an air scoop and may break off. F ailure to follow this warning may lead to personal injury and vehicle dam- age. W ARNING V ehicles with air fairings or large super- structures are tall.
284 Emergency Inf ormation T owing Instructions W ARNING If the vehicle becomes disabled, it is very important to tow it properly . Failure to do so can cause damage to the frame and body parts.
Emergency Inf ormation 285 Caging Spr ing Brak e Chambers The parking spring brake chambers may be released mechanically if there is no com- pressed air av ailable. Always start by chocking the wheels to prev ent the vehicle from rolling. Chock- ing the wheels is important since you hav e to work under the vehicle.
286 Emergency Inf ormation Install the washer and nut. Tighten the nut. This compresses the brake chamber spring and releases the parking brake. Do not attempt in an y way to disassem- ble or tamper with the spring brake chamber . If the force stored on the spring is suddenly released, it can cause serious personal injury or death.
