Page 306 A modern heavy-duty vehicle requires regular and preventive maintenance to ensure that all its components function as they should. Use the recommended preventive maintenance (PM) program that Volvo Trucks North America has developed for the vehicles. This ensures optimal energy efficiency from all components that are important to fuel consumption.
Page 307 OPERATION Brakes Dragging brakes increase fuel consumption. They should be checked regularly. It is important that the release action of the air valves is fast and that the moving parts of the wheel brakes are checked for good adjustment and operation. Axles An axle out of alignment increases rolling resistance.
Page 308 OPERATION 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 negative impact on fuel economy, as do hilly roads and uneven road surfaces.
Page 309 Starting the Engine Start the engine according to the instructions in the operator’s manual of the engine manufacturer (for a Volvo engine, see "STARTING THE ENGINE" “STARTING THE ENGINE” page 329). A proper start, especially during the cold season, saves fuel and reduces engine wear.
Page 310 OPERATION Air Tanks All air tanks on the vehicle should be drained daily. Empty any moisture from air tanks by pulling the drain valve wire or by opening the drain cocks and allowing the air pressure to drain completely. Make sure the drain cocks close properly after draining. During draining the tanks should be checked for condensation fluid even if an automatic drain valve is installed.

Page 314: Volvo Engine Brake (I-Veb)
RESUME. Volvo Engine Brake (I-VEB) The Volvo Engine Brake (I-VEB) is standard on the Volvo 16F engine and optional on the 13F engine. It has a higher braking effect than the variable geometry turbo brake. When the engine brake is in the A position and cruise control is engaged, the engine brake automatically engages if vehicle speed exceeds the set cruise control speed.
Page 315: Brake Operation
OPERATION BRAKE OPERATION Brake Safety Information DANGER DO NOT inspect or adjust parts or components in the brake system without setting the parking brake, placing the transmission 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 316 OPERATION DANGER DO NOT operate the vehicle when there is a malfunction in the compressed air system. An air brake system with leaks or other malfunctions may prevent the brake system from operating properly. The vehicle should not be operated until the system is repaired and all brake circuits are working properly.
Page 317 General All Volvo vehicles are designed to meet or exceed all applicable federal brake standards 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. Each circuit is supplied by its own compressed air tank.
Page 318 OPERATION DANGER Never release or drive a truck that has a brake discrepancy — no matter how minor — until it has been repaired or corrected. Failure to repair brake discrepancies can result in compromised brake efficiency and may lead to loss of control of the vehicle resulting in severe personal injury or death.
Page 319 OPERATION W3006936 W3006937 Gauge 1 and Gauge 2 Before operating the vehicle, check the air gauges which indicate air pressure. They should not register less than 420 kPa (65 psi).
Page 320 OPERATION 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 circuit becomes the emergency circuit for applying the brakes. W5001486 Clutch Fluid Reservoir Windshield Washer Fluid Fill...
Page 321 OPERATION W3005171 Master Warning Tell-Tale An important feature of the brake system is that an automatic spring brake application does not take place as a result of an air loss in only one of the two circuits. In this case, brake control remains in the foot brake valve.
Page 322 OPERATION Foot Brake Valve The foot brake valve is directly connected to the brake pedal. The valve gives a progressive output against the pedal travel. This allows better control of the pressure in the first half of the pedal travel. In the last half of the pedal travel, the pressure output increase is faster. The foot brake valve applies the service brakes, incorporating both the primary and secondary air systems.
Page 323 OPERATION The best possible stop will be made when the first brake application is as firm as the speed and road condition permit. Then, ease off as the speed is reduced. Never apply the brakes lightly at first and increase the pressure as the speed diminishes.
Page 324: Parking Brake/Trailer Supply Valves
OPERATION 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) W5001116 The System Park valve knob (yellow) should be pushed in first, after sufficient air pressure is built up (apply foot brake to prevent vehicle from rolling).

Page 329 OPERATION If the brakes are wet, drive the vehicle in low gear and lightly apply the brakes to heat and dry them. Allow hot brakes to cool before using the parking spring brakes. There are several ways to determine if the parking brakes have been set. By pulling out the yellow knob: •...
Page 330: Trailer Brake Hand Control
OPERATION Trailer Brake Hand Control DANGER 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 331 OPERATION W5001442 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 332: Anti-Lock Braking System (Abs)
OPERATION ANTI-LOCK BRAKING SYSTEM (ABS) The vehicle has a standard brake system, equipped with an electronic speed monitoring and control system, Anti-lock Braking System (ABS). ABS monitors wheel speed continuously but is not involved in controlling the wheel speed unless there is an emergency. In normal braking applications, the standard air brake system is in effect.
Page 333 If any of the ABS tell-tales come on during driving or do not go out after a short time after turning on the ignition, take the vehicle to an authorized Volvo Truck dealer to repair the ABS or brake system. The vehicle can still be driven with a problem in the ABS system.
Page 334: Volvo Enhanced Stability Technology
OPERATION VOLVO ENHANCED STABILITY TECHNOLOGY Some vehicles are equipped with Volvo Enhanced Stability Technology (VEST). VEST is an advanced stability control system designed to provide both roll stability and under- and over-steer correction in a wide variety of driving conditions. VEST continuously monitors a variety of vehicle parameters and sensors (including steering angle sensor) to determine whether the vehicle is reaching critical stability threshold.
Page 335 OPERATION W3000962 The TCS includes a switch to turn off the function. When the switch is in the OFF position, the TCS operates normally to increase traction if the drive wheels begin spinning. When the switch is pressed once, the TCS tell-tale in the instrument cluster blinks continuously, indicating that the TCS is in mud/snow mode.
Page 336: Vehicle Speed Retarding Devices
Volvo Variable Geometry Turbo Brake The variable geometry turbo brake is standard with the Volvo 11F and 13F engine. It uses software to close the variable geometry turbocharger to create retardation. Note: For both variable geometry turbocharger and engine brakes, use a "one gear" driving strategy when going downhill to keep engine speed up for effective braking (for example: uphill in 7th gear and downhill in 6th).
Page 337: Transmission Retarder, Vhd Only
OPERATION Transmission Retarder, VHD Only DANGER DO NOT use the retarder on wet or slippery roads. The retarder may cause vehicle to slide and cause an accident which could result in injury or death. CAUTION Apply the retarder only when engine is at closed throttle.
Page 338 OPERATION Note: The retarder is automatically disabled when the ABS (anti-lock brake system) is active. The Transmission Retarder is an option with Allison HD and MD transmissions. It is activated by an on/off switch in the auxiliary panel and is controlled by a stalk switch mounted in front of the wiper switch.
Page 339: Starting The Engine
Note: For cold weather starting, see “COLD WEATHER OPERATION” page 340. These starting and operating procedures should be followed for all engines. For more detailed information about design and function on a non-Volvo engine, read the operator’s manual from the engine manufacturer.
Page 340 OPERATION W0001484 DANGER Never operate the starter without first placing the transmission in neutral or depressing the clutch pedal. Failure to follow these instructions may result in the unintentional movement of the vehicle resulting in property damage, personal injury or death.
Page 341 Refer to the Driver Information Display Manual. 5. Turn the key to the start position. Release key as soon as the engine has started. For the Volvo engine, the preheater can be engaged to help starting in cold temperatures. CAUTION...
Page 342 OPERATION W3006933 6. When the engine has started, it takes a while to send lubricating oil to all bearings and shafts, and between pistons and liners. Wait for the oil pressure gauge to settle at a normal level, then bring engine speed up gradually. Increase speed as it warms up. Check all gauges during warm-up.
Page 343 OPERATION Engine Overspeed This vehicle is equipped with a diesel engine 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. The vapors may be drawn into the engine through the air intake and cause the engine to overspeed.
Page 344 OPERATION Note: Avoid excessive idling. If the vehicle is parked for more than 5 minutes, stop the engine. An engine can burn from 3 to 5.5 liters (0.75 to 1.5 gallons) of fuel per hour while idling. During long engine idling periods, the engine coolant temperature may fall below the normal operating range.
Page 345 Move the cruise control switch to the RESUME position and hold it there for four seconds. Release the switch. The engine speed will drop to the default low idle (Volvo engines), or a slight drop in idle speed will occur (Cummins).
Page 346 Parking brake is applied (Volvo engines only). These are standard choices when the vehicle is delivered. For more information about other customer adaptation choices, contact your authorized Volvo Truck dealer. Uphill Operation For best performance, allow engine speed to reach the bottom of the rated torque range before downshifting.
