Page 193: Antenna Multiplexer
Communication and Entertainment Antennas Multiband Antenna There are antennas mounted on the top of the mirror brackets for wideband reception. They receive or send signals for radio, CB and telephone. Each antenna carries multi- ple wire windings that work together with mirror bracket devices to cover the needs of many uses.
Page 194: Stereo/Radio
The multiplexer is accessed through the lower dash panels. Cable routing is as shown in the illustration above. Use only genuine Volvo replacement parts for this multiplexer system; standard antennas will give unsatisfactory performance. The wind- ings in the antennas are speciﬁc to this system: different sections of the antenna are used for the cellular phone, radio and CB.

Page 196: Fuel Economy Driving
Fuel Economy Driving Fuel Economy General The absolute fuel consumption (counted in miles per US gallon or liters per 100 kilo- meters) is determined by a large number of circumstances which can be related to one of the following main areas: Build speciﬁcation and equipment Service and maintenance External environment...
Page 197 Fuel Economy Driving Driveline Combination Engine, transmission and ﬁnal drive must be selected in such a way that the engine can operate within the economic speed range at normal driving speed. This range is deﬁned as where the engine makes the best use of the energy content of the diesel fuel.
Page 198: Service And Maintenance
Use the recommended preventive maintenance (PM) program that Volvo Trucks North America, Inc. has developed for the vehicles. This ensures optimal en- ergy efﬁciency from all components that are important to fuel consumption.
Page 199 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. A good sign of an axle or wheel out of alignment is uneven tire wear.
Page 200 Fuel Economy Driving External Environment Under unfavorable conditions, the external environment can have a negative effect on fuel consumption. This can be broken down into two main groups: weather and wind; and the nature of the roads. Rain, snow, icy conditions and headwinds have a large neg- ative impact on fuel economy, as do hilly roads and uneven road surfaces.
Page 201 Starting the Engine Start the engine according to the instruc- tions in the Operator’s Manual of the engine manufacturer (for a Volvo engine, see page 198). A proper start, especially during the cold season, saves fuel and re- duces engine wear.
Page 202 Fuel Economy Driving Avoid High Engine Speeds High engine speeds mean high fuel con- sumption. Jerky driving also increases fuel consumption when the vehicle is constantly accelerated and slowed down. Avoid a higher consumption by steady, even driving. Refer to each engine manufacturer’s opera- tor’s manual for information on the engine’s optimum operating range.

Page 222: Uphill Operation
Engine Start 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. Continue to operate at the rated torque if the vehicle will make it to the top without a downshift.
Page 223: High Altitude Operation
Engine Start and Operation 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 level. For naturally aspirated engines, this loss is about 3 percent per 1000 feet (300 m) in- crease in altitude above sea level.
Page 224: Cruise Control
Engine Start and Operation Cruise Control Do not use the cruise control in heavy trafﬁc, with ice/snow on the road or dur- ing other unfavorable conditions. This may lead to a loss of vehicle control, causing a vehicle crash and can result in personal injury or death.
Page 225 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.
Page 226: Fuel Tank(S)
Engine Start and Operation Fuel Tank(s) Tank Cap Do not remove the fuel tank cap near an open ﬂame. Diesel fuel vapors are com- bustible and can cause an explosion or ﬁre, resulting in severe personal injury or death. The fuel tank caps have a pressure and a thermal relief function built into the cap.
Page 227 Fueling Air is always present inside the fuel tanks, entering mainly through the tank ventila- tion. With the air being heated up and cooled down, condensation is formed and water is mixed in the fuel. To avoid con- densation when the vehicle is parked for longer periods, ﬁll the tanks up to 95% of capacity.
Page 228: Clutch And Transmission
Clutch and Transmission 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 vehicle movement and can cause serious personal injury and death. Do not allow the clutch to slip excessively. This would cause excessive heat to be gen- erated and the clutch will be damaged and bring on premature failure.
Page 229: Brakes
Brakes Brake Safety 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 prevent uncontrolled vehicle movement, it could roll and cause severe personal injury or death.
Page 230 General All Volvo vehicles are designed to meet or exceed all applicable federal brake stan- dards and regulations. They use a dual circuit, compressed air system. It consists of two independent brake systems that use a single set of brake controls.
Page 231 Both circuits are piped into a dual brake valve, which simultaneously applies front and rear axle service brakes during each brake application. In the event of a failure in either one of the circuits, the other cir- cuit becomes the emergency circuit for applying the brakes.
Page 232: Brake System Controls
Brakes Brake System Controls The air compressor, governor, pressure reg- ulator valve 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.
Page 233 From the operator’s viewpoint, operating the foot brake valve of a vehicle equipped with air brakes differs very little from the operation of a conventionally braked vehi- cle. Because the operation of the brake pedal requires scarcely more effort than de- pressing the average throttle pedal, air brakes are naturally much easier to control.
Page 234 Brakes In making a stop or a slow-down, al- low the transmission to remain in gear with the throttle closed, disengaging the clutch only when engine idling speed is reached. When parking the vehicle, place the transmission in neutral and set the parking brake before shutting down the engine.
Page 235 Parking Brake/Trailer Supply Valves Trucks/Tractors may have two air control valves on the instrument panel: • Trailer Supply (red octagonal knob) • System Park (yellow diamond knob) The two air control valves are intercon- nected and interacting. The System Park valve supplies and controls the Trailer Air Supply valve.
Page 236 Brakes Parking Brake Release VHD models have 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.
Page 237 Brakes 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 save fuel. This is activated when the yellow parking brake knob is pulled out. There- fore, some drivers park and release the parking brakes using only the red knob to keep the engine running.
Page 238 Brakes Spring Brake For Parking Never leave the vehicle without being certain the parking brakes are set or that other precautions are taken to prevent the vehicle from rolling. Failure to do so can result in serious personal injury or death. The parking brake mechanism uses spring pressure as a separate power medium to ap- ply the service brakes on the driving axles.
Page 239 There are several ways to determine if the parking brakes have 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 valve itself and from the spring brake chambers on the rear axle(s).
Page 240 Brakes Trailer Brake Hand Control The trailer hand brake control is not a parking brake valve 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 movement of the vehicle and may cause personal injury or death.
Page 241 The “121” Brake Standard This manual refers occasionally to “121” brakes. Although some operators believe “121” only applies to vehicles equipped with anti-lock devices, the “121” standard applies to all vehicles that are capable of on-highway operation. The “121” is a Federal requirement also covering alterations or changes to parts or systems related to the “121”...
Page 242: Antilock Braking System (Abs)
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 but is not involved in control- ling the wheel speed unless there is an emergency.
Page 243 Volvo Truck dealer to repair the ABS or brake system. The ve- hicle can still be driven with a problem in the ABS system.
Page 244 Brakes Traction 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. If the TCS determines that a wheel is spinning (with vehicle speed below 25 mph [40 km/h]), it operates the brake system to apply some brake force to...
Page 245 NOTE! If a Volvo engine is equipped with a Volvo Engine Brake, the brake will not operate with full power until the engine coolant temperature has reached 110 F (45 C).
Page 246 Brakes Volvo Exhaust Brake The exhaust brake is standard on the Volvo D12 engine. It is used to reduce wear on the brake linings. The exhaust brake is most effective 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.
Page 247 3 mph (5 km/h) above selected cruise speed. Too Cold for Engine Brake (Volvo Engine Only) Position 2 of the engine brake should not be switched on until the engine has become warm (over 110 F [45 C]).
Page 248 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 levels are available by engaging 2, 4, or 6 cylinders when brak- ing (for Cummins M11, only two power levels are available).
Page 249 Transmission Retarder The Transmission Retarder is an option with Allison HD and MD transmissions. It is activated by an on/off switch in the aux- iliary panel and is controlled by a stalk switch mounted in front of the wiper switch. You can set 6 different levels with the stalk switch.

Page 255: Electronic Components
Electronic Components CAUTION Electronic circuits and components are designed to sense voltage differences smaller than 1 volt. While static electric- ity is not normally dangerous to humans, it can seriously damage electronic cir- cuits and components. Circuit boards mounted in the instrument cluster may not fail immediately after being hit with a static discharge.
Page 256 Electrical System CAUTION If there are other ground cables con- nected to the battery (such as engine ECU, etc.), disconnect those ground ca- bles ﬁrst, then remove the main battery ground cable. Electronic modules may be damaged when additional grounds are connected/disconnected without the main battery ground connected.

Page 258 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 level. Before disconnecting, the monitor will sound a loud and distinct alarm, alternating long and short beeps, for approximately 60 seconds.
Page 259: Electrical Center
Electrical Center The electrical center is located in the mid- dle of the dash. All the relays and fuses in the cab are collected here. The cover panels are fastened with screws that can be turned with a coin. Since the function of some fuses or relays may change for the vehicle application, refer to the list of functions that is attached to the underside of each panel.
Page 260 Electrical System The fuses and relays are all accessible un- der the top cover on the dash. W3002526 One type of fuse in the new electrical cen- ter are termed “mini-fuses” and require a puller tool to remove from the fuse block. The puller tool is part of the Owner’s Pack- age.
Page 261 Power 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. CAUTION If stripped wire ends are used, make sure there are no wire strands that can bridge between the studs.
Page 262: Power Steering
Power Steering General The power steering consists of an inte- grated gear and hydraulic power cylinder, and a power steering pump with ﬂuid con- tainer. The pump, driven by the engine, provides hydraulic pressure to the power steering. If the engine is not working, the steering is only manual.
Page 263: Adjustable Steering Column (Option)
Periodically check the power steering ﬂuid reservoir and keep it ﬁlled to the proper level 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. Adjustable Steering Column (option) The steering column is ﬁxed as standard.
Page 264: Differential Locks
Axles and Wheels Axles Differential Locks The drive axle(s) may be equipped with differential locks. The single drive axle will only have a wheel differential lock. With tandem drive axles, there could be both wheel differential locks and an inter-axle differential lock.
Page 265 Engaging the differential locks must always be done in the following way (see page 104 for switch location): Depress the clutch pedal. Wait for the drive wheels to stop spinning Engage the differential lock Engage a suitable gear Carefully release the clutch pedal Do not drive on dry, paved surface with the differential locks engaged.
Page 266 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 movement. 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.
Page 267: Wheels
General Due to the size, equipment needed and the procedures used to change wheels, this should be done through the Volvo Truck dealer. By having an expert technician per- form this procedure, personal injury and property damage may be avoided.
Page 268: Inflating Tires
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. CAUTION Never bleed the air from hot tires. In- creased tire pressure measured in a hot tire is normal.
Page 269: Wheel Bearing Adjustment
Loose wheel bearings could cause premature tire wear and possibly affect ve- hicle handling. See your Volvo Truck dealer for proper servicing. Watch carefully for oil leaks and listen for unusual noises. These are indications of worn bearings, bad seals or misadjusted bearings.
