General Information 1

Information For the Owner

If there are questions on the maintenance and performance of your vehicle, please discuss them with your Volvo Truck dealer. Your authorized dealer is required to have trained mechanics, special tools and spare parts to fully service your vehicle. If necessary, your dealer will contact the manufacturer for any assistance.

In addition to this Operator’s Manual, there may be additional instruction/operator’s manuals supplied by component manufacturers. These manuals are placed in the Owner’s Package and placed in the cab. Be sure to read all the manuals thoroughly before operating the vehicle.

Also, various safety labels may be placed on components by the component manufacturer. Be sure to read and follow these labels to prevent damage to the vehicle, personal injury or even death.

Information in this manual refers to Volvo components and Volvo drivetrain. Information concerning non-Volvo engines and/or drivetrains can be obtained by contacting the respective manufacturer.

Establish a Preventive Maintenance Program with the help of your local Volvo Truck dealer. A Preventive Maintenance Program makes it possible to maximize the amount of time your vehicle is up and running, resulting in longer component life. This makes for a safer vehicle by reducing any mechanical failures due to poor maintenance practices.

Various truck warranty coverage plans, contingent on application and weight class, are available. Please contact an authorized Volvo Truck Dealer for complete details. Replacement warranty certificates for Volvo Trucks are available from Volvo dealers.

For trucks placed in service after August 1, 2000 and operating in the USA and Canada, Volvo dealers can print copies of the Standard Truck Warranty Certificate and the Premium (Purchased) Truck Coverage Certificate. Copies are available in either English or Canadian French at the dealer communication system (DCS) website. Look in the Service/Warranty folder.

NOTE! Federal law requires manufacturers to notify owners of its products in the event of a non-compliance to a Federal Motor Vehicle Safety Standard or if a safety related defect is discovered. If you are not the original owner of this vehicle, please notify us about the change in ownership at the address below or through an authorized Volvo Truck dealer. This is the only way we will be able to contact you if necessary.

General Safety Information

Operating the Vehicle

Every vehicle, including heavy duty vehicles, has blind spots. The size of blind spots varies from driver to driver and from situation to situation. As a skilled, professional driver, you are in the best position to avoid accidents in turns, lane changes or other maneuvers. Volvo Trucks North America, Inc. provides standard equipment (such as cabs, windshields, window sizes and mirrors), preferred by most owners and drivers under most conditions and in most applications.

However, due to differences in the size of drivers, their seating positions, the way that they use and operate their vehicles, personal preferences and other factors, no combination of mirrors and other visibility enhancement devices will eliminate all blind spots in every situation.

The safe operation of this vehicle is up to you. Because of your special preferences, needs and circumstances, you may want to add extra mirrors and/or other visibility enhancement devices. If so, you should contact an authorized Volvo Truck dealer to obtain those parts which best fit your own personal needs and preferences.

WARNING

All items within the cab must be secured before the vehicle is set in motion. This includes, but is not limited to, drinks, clothes, books, televisions, etc. In the event of a collision, loose items could fly around inside the cab. This could cause personal injury.

Never try to operate or work on this vehicle while under the influence of alcohol. Your reflexes can be affected by even a small amount of alcohol. Drinking and operating this vehicle can lead to an accident, causing serious personal injury or death.

4 General Information

Operating In Bobtail Mode

Tractors are equipped with a bobtail air brake proportioning valve which automatically redistributes the braking force between front and rear axles when not hooked up to a semitrailer (bobtail operation).

When operating in bobtail mode, the rear brake chambers receive reduced or proportional brake air pressure. When the tractor is towing a trailer, the rear brake chambers will receive full (normal) brake pressure.

NOTE! When operating bobtail, be certain that glad hands, trailer air hoses, electrical cable and connectors are properly stowed and secure. Do not allow them to rub or chafe on other components.

WARNING

When operating bobtail, the brake system on the vehicle reduces the possibility of rear wheel brake lockup, except on full pedal application. When bobtailing, be certain that adequate pedal pressure is applied. There is no need to reduce pedal effort. Failure to do so may result in increased stopping distances.

General Information 5

Do Not Overload

This vehicle has been designed and assembled for a maximum gross vehicle weight rating (GVWR) and a maximum front and rear axle weights rating (FAWR and RAWR). The actual rating for this vehicle can be found on the label attached to the door frame on the driver’s side. If any of these three ratings is exceeded and overloading occurs, instability, poor handling, failure of parts and accelerated wear can occur.

Under no circumstances should the published GVWR, FAWR, and/or RAWR be exceeded. Failure to observe these precautions can lead to the loss of vehicle control, resulting in a crash causing serious personal injury or death.

W0001210

Do not exceed the load rating of the tires or the vehicle weight ratings. Overloading may result in tire failure causing loss of vehicle control, leading to an accident resulting in severe personal injury or death.

Operating

Before driving this vehicle, locate the instruments and controls, and become thoroughly familiar with their operation. After starting and when driving, always check to make sure that the instrument readings are normal.

The cab door is unlocked with the same key used for the ignition lock. Keys can be made to fit only one vehicle or all the vehicles in a fleet of Volvos. A tool for changing bulbs in the instrument cluster is included on the keychain.

The key fits in the door lock either way. Insert the key and turn it 1/4 turn counterclockwise to unlock or clockwise to lock the door.

NOTE! The vehicle is delivered with 2 identical keys. If more keys are needed, order them through your Volvo Truck authorized dealer. The keys are laser cut and require a special machine for copying, available through the dealer. Record the key code and keep it in a secure place. A new key can be made if the keys are lost.

The door locks are mechanically or electrically operated. The lock is activated by either the key from the outside or the door lock handle from the inside. With mechanical locks, only one door can be locked/unlocked at a time. With electrical locks, both doors will be locked/unlocked by operating either the key or the inner door lock handle on either side.

To lock either door from the inside, push the door lock handle forward. The handle will stay in place, indicating the door is locked. It can be unlocked without opening the door by moving the door lock handle to the middle position.

No door can be locked while it is still open. The door must be closed for the lock to work. In the event of a power failure the electrical lock system reverts back to a mechanically functioning system.

Cab Entry and Exit

General

To avoid personal injury due to a slip and/or fall, observe all the guidelines explained in this section marked Cab Entry and Exit.

Do not stand on the steps or any other part of the vehicle while it is in motion. The steps and the back of cab access deck plates are only for entering/exiting the vehicle and not for riding on. Failure to heed this warning can result in serious personal injury or death.

Steps are designed to be slip resistant and to provide a stable surface for entering or exiting the cab. However, accumulation of ice, dirt, lubricants, etc. on the steps can make entering or exiting hazardous. Always make sure the steps are free from slippery substances. Failure to follow this guideline may result in a fall that can cause serious personal injury or death.

WARNING

Wearing shoes with soles that are dirty or wet increases the chance of slipping and falling. Be careful when entering the cab with dirty or wet soles.

WARNING

Both the operator and passenger should exercise caution when entering or exiting the cab. Use the steps and grab handles to safely get in and out of the cab.

W8002808

General Entry Guidelines

To avoid personal injury due to a slip and/or fall, observe the following guidelines.

1Always have three limbs (one foot and two hands or two feet and one hand) in contact with the vehicle at all times when entering or exiting the cab or the area behind the cab.

2Be certain you have a firm handhold and/or stable foot position before transferring weight to that position. For example, do not start to put weight on a foot until you are certain your foot is properly on the step and will not slip when you transfer your weight.

3Do not climb on top of the frame, fuel tanks or storage boxes to make trailer hook-ups.

4If the vehicle is equipped with air fairings, do not use the side mounted fairing (wind deflector) brackets and braces as steps or grab handles.

5Be certain that the grab handles are clear of snow, mud, ice or other substances that could make them slippery before using them. Do not use steps or grab handles if they are slippery or damaged.

6Be certain that all grab handles, steps and related parts are in good working condition. Any defects should be reported and repaired before using the grab handles and steps.

7Do not step on the curved surface of the fuel tanks. They may be slippery from snow, mud, ice, water, spilled fuel or other slippery substances.

8If a step is mounted to the top of the battery box, be certain that the battery box cover is properly fastened before stepping.

9Do not jump from the cab or from the steps to the ground.

10Always face the cab when entering or exiting.

11Do not hold anything in your hands when entering or exiting the cab or the area behind the cab. Log books, cups, clipboards, jackets, luggage and the like can be placed on the cab floor or rear deck plate before entering or exiting.

12Be sure to disconnect the safety belt before exiting the cab.

13Be sure that the safety belt is fully retracted and out of the way prior to entering or exiting the cab.

14Do not put your foot on any surface that does not have slip resistant, selfcleaning material. If there is no step material, the surface may be slippery and you could fall.

15Before entering or exiting, be certain that the soles of your shoes/boots are free from grease, mud or any other substance which could make them slippery.

16Always put the foot flat on the top of the step. Do not place your foot on the side or edge of the step.

Hood

The hood is locked down by two latches, one on each side of the back end of the hood. The latches are operated by a handle on the bottom edge of the dashboard.

Pull the bottom of the handle out to release hood. The hood will be raised about two inches off its resting position and remain there.

Make sure the hood can be opened fully without hitting anything. Stand sideways in front of the hood with feet in line with the vehicle. Place feet well apart and grasp the recessed handle in the front part of the hood. Transfer the body weight by leaning away from the hood. Lift the hood until it is past the balance point. Release the hood and let it complete the opening movement unaided.

Two restraint cylinders will engage during the last part of the opening. The cylinders will slow and dampen the hood down to its resting position.

WARNING

Make sure that no one is in the way of the hood when closing. The hood could injure a person in the way while being lowered.

To close the hood, stand with feet well apart and place the hands along the front edge of the hood. Bend the knees and let the leg muscles do the work when lifting.

Raise the hood up to the halfway point. Carefully guide the hood down with enough speed that the hood latches lock the hood in place when it comes to its normal resting position.

28 Pre-Trip Inspection and Daily Maintenance

General

Before working on or inspecting a vehicle, set the parking brakes, place the transmission in neutral and block the wheels. Failure to do so can result in unexpected vehicle movement and can cause serious personal injury or death.

Safety is the most important and obvious reason for doing a pre-trip inspection. Federal and state laws require inspection done by the driver. Federal and state inspectors also inspect commercial vehicles. An unsafe vehicle can be placed “out of service” until the driver or owner corrects the deficiency. Owners and operators should familiarize themselves with sections 49 CFR 396.11 and 396.13 concerning Federal requirements for vehicle inspection. Certain other laws may also apply.

Section 49 CFR 396.13 states that all motor carrier drivers must complete a written report at the end of each work day for each vehicle operated, covering most of what is covered in the pre-trip list. The report should list all defects or deficiencies discovered by the driver. Doing a pre-trip inspection prepares for the end-of-work report.

Starting on the next page are suggested guidelines to be used in performing truck, tractor and trailer pre-trip inspections. De-

pending on the application of the vehicle being used, these guidelines should be modified to include other necessary inspection points. For example, steps and grab handles should be checked daily on refuse trucks because the operator is getting in and out of the cab more frequently.

If any component or system does not pass this inspection, it must be corrected before operating the vehicle. Whenever equipment requires adjustment, replacement, repair or lubrication, refer to the Service Manuals or contact a Volvo Truck dealer for the correct procedures, specifications and intervals.

Take your time going through the pre-trip inspection. Remember that a careful pre-trip inspection saves time by eliminating unscheduled stops for correcting a faulty item.

The following information has been provided by the American Trucking Association as developed by the D.O.T. Office of Motor Carriers (BMCS).

Pre-Trip Inspection and Daily Maintenance 41

Daily Maintenance

The following should be checked daily in addition to doing the pre-trip inspection of the truck or tractor and trailer.

While checking the fluid levels, visually inspect hoses, pipes and their connections for signs of leakage. Inspect the ground under engine, transmission and rear axle(s) for signs of leakage.

Check coolant level in the coolant tank. The level should be above the minimum mark shown on the side of the tank.

WARNING

Do not remove the cap to the surge tank while the engine and radiator are still hot and under pressure. Scalding fluid and/or steam may be blown out under pressure if the cap is taken off too soon.

If the coolant level is low, add more coolant to the tank so the level is above the minimum mark. Coolant should be filled through the cap in the middle of the tank.

Before working on or inspecting a vehicle, set the parking brakes, place the transmission in neutral and block the wheels. Failure to do so can result in unexpected vehicle movement and can cause serious personal injury or death.

W2003475

CAUTION

Add only pre-mixed coolant made up of 50% clean water and 50% antifreeze. See the “Operator’s Manual, Maintenance & Engine” for more detailed information.

CAUTION

Engines equipped with automatic start systems can start automatically. Alarm sounds before automatic start. Failure to turn off ignition before working on fan or belts can result in personal injury.

42 Pre-Trip Inspection and Daily Maintenance

WARNING

Keep yourself clear of all moving or hot engine parts. A hot engine can cause serious burns.

Check oil level in the engine with the dipstick. The oil level should be between the minimum and maximum marks on the dipstick. Do not overfill!

See the “Operator’s Manual, Maintenance and Engine” for correct types of oil used in Volvo engines.

CAUTION

If the vehicle is equipped with an aerodynamic bumper, do not step on or press in between the bumper and the wheel. Breakage or damage may result.

To add oil to a D12 engine, remove oil cap on the valve cover and fill through the hole. There is also a right-side oil fill.

CAUTION

Make sure the oil added is the same type of oil that is in the engine. The wrong type of oil could accelerate wear on engine if not suited for application.

Safety belts must be properly worn at all times by the driver and all passengers while the vehicle is in motion even if the vehicle is equipped with a Supplemental Restraint System (SRS or air bag). Failure to do so can result in serious personal injury or death in the event of a collision.

Fasten the safety belt before starting to drive. Trying to fasten the safety belt while the vehicle is moving may lead to an accident, causing serious personal injury or death.

Safety belt assemblies installed in this vehicle meet FMVSS 209, “Type 1” and “Type 2” requirements. They are recommended for all persons weighing over 50 lb (25 kg).

A child restraint system should also be provided for each child weighing 50 lb (25 kg) or less. It should meet the requirements of FMVSS 213, “Child Restraint System.” Carefully read and follow all manufacturer’s instructions on installation and use. Make certain the child remains in the restraint system at all times while the vehicle is in motion.

Additional Safety Features 47

Safety belts must be worn by the driver and all passengers at all times. Before adjusting or fastening the safety belt, move the seat forward or rearward and adjust the seat height as necessary. Sit erect and adjust the seat cushion and seat back for a comfortable driving position. In the event of a collision, a correct driving position maximizes the effectiveness of the safety belt.

There are both Federal and State laws governing the use of safety belts. As laws differ from state to state, make yourself familiar with the current rules.

W8001077

Tether straps are installed on some suspension-type seats. Tether straps help secure the seat to the floor and are intended to restrain the seat and safety belt in case of an accident or sudden stop.

The tethers are not adjustable and do not need any adjustment.

W8001387

48 Additional Safety Features

Operating the Safety Belt

To fasten the safety belt, pull the belt out from the retractor and insert the latch into the buckle. Verify proper lock of the latch by pulling on the latch.

Adjust the slack by pulling on the top part of the belt until the lower part, or the part that crosses the lap, is snugly adjusted. Release the top part and let the retractor pull the belt in.

The lap portion of the safety belt should be worn low across the pelvic region (hip bone) and adjusted snugly. Never adjust the lap belt across the abdomen. A push button on the buckle is used to release the safety belt latch by pushing in the button release on the buckle.

The buckle portion of the safety belt system is different depending on the seat option chosen. The National Standard and Comfort seat has a separate buckle that is attached to a floor anchor by a seat strap. This seat strap is not adjustable, and does not need to be adjusted.

The buckle for the Volvo seat is part of the seat frame.

If a comfort clip is used on the safety belt, always adjust the latch so that there is a maximum of 1 in. (25 mm) slack between the belt and chest (about the width of two fingers). If a larger slack is allowed, the effectiveness of the safety belt is decreased in the event of a collision. Operation of the clip is described on page 54.

Make sure the safety belt is completely retracted and out of the way when not in use.

Additional Safety Features 49

Inspection

Failure to properly inspect and maintain the safety belts can cause serious personal injury or death.

It is critical that any time a vehicle has been involved in an accident, the entire safety belt system must be replaced in the vehicle (which also includes the sleeper bunk restraints) if they were in use at the time of the accident. Failure to replace the safety belt system may result in serious injury or death.

A damaged safety belt, whether visibly damaged or not, could result in serious personal injury in the event of an accident. The safety belt systems should be replaced at least every five years.

Do not bleach or re-dye the color webbing because it may cause a severe loss of belt strength. This loss of strength could allow the safety belt to break under stress, thus resulting in severe personal injury or death.

Check the belts, buckles, latch plates, retractors, anchorages, and guide loops to ensure that they are working properly. Look for loose/damaged parts (without disassembling) that could keep the restraint system from working properly. If the safety belt, retractor and hardware were in use during a collision, they must be replaced. The restraint system anchorage fasteners must be replaced if necessary. If there is any doubt about the restraint system’s effectiveness, replace the entire safety belt assembly.

50 Additional Safety Features

The following maintenance guidelines detail how to inspect safety belts and tethers for cuts, fraying, extreme or unusual wear of the webbing, etc., and damage to the buckle, retractor, hardware or other factors which indicate that safety belt system replacement is necessary.

Check the web wear at the buckle/latch area. The webbing must be closely examined to determine if there are any cuts, fraying or extreme wear in the webbing. Cuts, fraying or excessive wear would indicate the need for replacement of the safety belt system.

W8001406

The D-loop web guide is an area where almost constant movement of the safety belt webbing occurs because of the relative movement between the seat and the cab. This constant movement forms an area where wear will often occur. The webbing must be closely examined to determine if there are any cuts, fraying or extreme wear in the webbing. Cuts, fraying or excessive wear would indicate the need for replacement of the safety belt system.

W8002478

Additional Safety Features 51

Check to make sure that the D-loop web guide is rotating properly. If the guide is not rotating properly, the webbing will pull at the wrong angle through the guide, accelerating wear.

W8002477

If equipped, check the comfort clip for cracks or possible damage. Make sure that it works properly.

Check the buckle by inserting the latch and verifying proper operation. Determine if the latch plate is worn or deformed. Check the buckle and latch casing for cracks or breakage.

W8001404

52 Additional Safety Features

The retractor web storage device is mounted on the B-pillar, just behind the door in the cab. The retractor is the heart of the safety belt system and can be damaged if abused, even unintentionally. Check the retractor web storage device operation to ensure that it is not locked and that it spools out and retracts the webbing properly.

W8002481

If tethers are being used to anchor the safety belts to the floor, make sure that they are properly attached to the seat. Tethers must also be inspected for web wear and proper tightness of mounting hardware.

W8001387

All hardware for safety belt mounting points should be evaluated for corrosion. All attachment points of the system should be checked for tightness of mounting hardware.

Check the web in areas exposed to ultraviolet rays from the sun or extreme dust or dirt. If the original color of the web in these areas is extremely faded, the physical strength of this web may have deteriorated. If this condition exists, replace the safety belt system.

Additional Safety Features 53

Important Facts About Safety Belts in Heavy Trucks

The high mileage associated with heavy trucks, the continual relative movement of the seat with the cab, the possible contact with the vehicle seat or other parts of the cab structure, and the potential exposure of this safety belt to severe environmental conditions make it crucial to inspect the seat belt system regularly. It is recommended that the system is inspected every 15 000 miles (24 000 km) or more often if the vehicle is exposed to severe environmental or vocational conditions. Any safety belt system that shows cuts, fraying, extreme or unusual wear, significant discolorations due to ultra-violet ray exposure, dusty-dirty conditions, abrasion to the safety belt webbing or damage to the buckle, latch plate, retractor, hardware or any other obvious problem should be replaced immediately, regardless of the mileage.

Once replacement of the safety belt has been determined necessary, be certain that it is replaced only with a Volvo original replacement safety belt. See your authorized Volvo Truck dealer for replacement. Your Volvo safety belt system has been developed and tested specifically for heavy trucks. Replace it only with the exact same design that the vehicle was equipped with.

If the inspection indicates that any other part of the safety belt system requires replacement, the entire belt system must be replaced. An installation guide is attached to every replacement system, entitled “Three-Point Safety Belt Installation Guide.” There are separate safety belt instruction guides for suspension and stationary seats. Use the proper guide for your type of seat and follow the instructions very closely. It is vitally important that all components are mounted back in the same positions as the original components that were removed. This will maintain the design integrity of the mounting points for the safety belt assembly.

54 Additional Safety Features

Comfort Clip Operation

When provided, the comfort clip is located on the shoulder strap just below the D-ring.

When adjusting the comfort clip, the following procedure must be followed for proper adjustment:

1Pull out only enough webbing to allow slight pressure to the shoulder and chest. Allow no more than a 1 in.

(25 mm) slack when measured between the chest and the belt.

2To activate the clip mechanism feature, lift the lever up to clamp the webbing in place.

NOTE! When the safety belt is not in use, the clip should be in the open position to allow the seat belt to retract to its proper position. Also make sure that the adjustment of the comfort clip does not interfere with the operation of the safety belt.

Always adjust the clip so that there is a maximum of 1 in. (25 mm) of slack between the belt and chest (about two fingers width). If a larger slack is allowed, the effectiveness of the safety belt is decreased in the event of a collision.

Additional Safety Features 55

SRS Airbag

WARNING

The SRS airbag is intended to supplement — not replace — the standard safety belt. The airbag is not deployed when the truck is hit from behind, from the side or if it rolls over. For best protection, sit in a normal, upright position.

Always wear the safety belt.

For added safety, the vehicle may be equipped with an airbag or SRS (Supplemental Restraint System) as a supplement to the standard three-point anchored safety belt. The SRS is designed to reduce the risk of injury to the driver’s face and upper part of the body. Together with the safety belt, the airbag helps prevent the driver from being thrown against the steering wheel, windshield or other hard surfaces in the cab.

The Volvo SRS Airbag provides increased protection in frontal collisions, where the vehicle collides with a fixed or heavy object with enough force to activate the sensors which then activates the airbag. Damage to the vehicle is not always proportional to whether the SRS Airbag deploys or not.

The SRS Airbag is not designed to be activated with:

Collision from the sides

Collision from the rear

Rolling over

Head-on collisions at low speed or against soft objects such as bushes, snow drifts, etc.

56 Additional Safety Features

SRS System

The inflatable airbag is folded into the center of the steering wheel. It inflates in the event of a serious collision above a certain level, where the angle of impact, crash severity, speed and nature of the object involved in the collision all play a part in whether or not the airbag is activated.

The system consists of a gas generator surrounded by the inflatable airbag. In the event of a sufficiently violent collision, a control unit activates the gas generator ignitor and the airbag inflates and heats up at the same time. To cushion the impact, the airbag deflates when compressed. This also releases some non-toxic smoke into the cab. The entire sequence, from inflation to deflation of the airbag, takes a few tenths of a second.

WARNING

Never attempt to drive with a deployed airbag. With the bag hanging out of the hub of the steering wheel, the truck may be more difficult to steer. In addition, other safety systems may be damaged. Continuous exposure to the smoke and dust created during the deployment of the airbag can cause irritation to the skin and eyes.

T8006849

T8006855

Additional Safety Features 57

The SRS system is continually monitored by the control unit. A control unit is mounted on a bracket above the engine cover which detects deceleration. The control unit also contains a standby power unit which can supply the system with power for a short time, should the normal supply be broken.

If the control unit detects a sufficiently violent deceleration (collision), the system is activated. The gas generator triggers and fills the bag with a non-toxic gas within a few hundredths of a second. During a collision, after the bag has been filled, gas flows out through two holes in the weave. These holes are large enough to let the airbag collapse slowly, gently catching the driver.

In the event of a problem in the SRS system, a telltale shows on the graphic display in the instrument cluster. This telltale, together with other telltales in the cluster, also light up when the engine is started. The telltale should go out after approximately 10 seconds when the starting key has been turned to the drive position.

If a problem develops in the system, the 1INFO telltale will come on together with the SRS telltale.

CAUTION

The vehicle should be taken to an authorized Volvo Truck dealer immediately if the SRS telltale stays on or lights up when the vehicle is being driven.

58 Additional Safety Features

Warning Labels

The label attached to the left hand sunvisor shows the year and month when a Volvo Truck dealer should be contacted for a specific inspection and for a possible replacement of the airbag. This is done to guarantee the function of the airbag after the stated date. Replace the label when replacing the airbag module. Never attempt to make any adjustments to SRS compo-

nents yourself.

T8006843

Steering shafts and steering wheel should not be removed, adjusted or replaced without following the proper work procedure. Failure to do so can damage the SRS system to the point where it does not work any longer. A warning label is located on the

upper steering shaft.

T8006842

There is also a label on the inside of the windshield that indicates the inclusion of an airbag to the vehicle safety features.

T8006841

When equipped with an airbag, a label about the correct procedure for protecting small children and protecting the driver is attached to the left hand, overhead storage lid or back of sunvisor.

W8002741

Additional Safety Features 59

Any queries concerning the SRS system should be directed to a Volvo Truck dealer. There is no maintenance required for the SRS system until the date stated on the warning label located on the left hand sunvisor.

Never attempt to repair any part of the SRS system. Any interference with the system may cause it to malfunction and result in serious injury. Work on the system may only be carried out by an authorized Volvo Truck dealer.

To allow the SRS system to work as designed:

Never drive an SRS system equipped vehicle with the hands on the steering wheel pad/airbag module.

No objects, accessory equipment or stickers may be placed on, attached to or installed near the SRS cover in the center of the steering wheel.

60 Additional Safety Features

General Information

When is the airbag deployed?

The airbag is only deployed during a headon collision, where the vehicle hits a fixed or heavy object with sufficient force. The SRS system registers both the force of the collision and the internal forces caused by the collision. The control unit determines if the collision is sufficiently violent for the airbag to be deployed.

NOTE! The SRS system is only activated once in a collision. If the airbag has deployed, the following is recommended:

Have the vehicle towed to a Volvo Truck dealer. Even if the vehicle can be driven after a collision, it is not recommended to drive the truck with the airbag deployed.

Have an authorized Volvo Truck dealer change the components in the SRS system.

Only use original Volvo parts when replacing the SRS system components (airbag, safety belt, etc.).

When is the airbag not deployed?

Not all frontal collisions activate the SRS system. In a collision with a soft object (a snow drift or bush for example, or a hard or fixed object at low speed), there is no need for the SRS system to be activated. The airbag is usually not inflated in response to side-on collisions, impacts from the rear or if the vehicle overturns. The extent of damage to the vehicle is no measure of how well the SRS system works.

Additional Safety Features 61

Can the airbag be deployed accidentally?

The complete SRS system is constructed so that the airbag only inflates in particular collision conditions. The SRS system has its own diagnostic unit which continuously monitors the functioning of the system. Make a habit of checking the SRS system telltale light when starting and driving the vehicle.

Heart of the Volvo safety system

The three-point anchored safety belt is the heart of the Volvo safety system. The belt should be worn at all times. The SRS system is intended as a supplement to the three-point anchored safety belt.

62 Additional Safety Features

Safety Equipment

Safety triangles and fire extinguishers are available as optional equipment. The fire extinguisher should be located by the base of the driver seat, between the seat and the door.

The warning triangles are stored in a box that is strapped to the back wall of the cab.

W0001372

Additional Safety Features 63

VORAD Collision Warning System

The Eaton VORAD computerized Collision Warning System constantly monitors vehicles ahead with a front end mounted radar and in a blind spot area with an optional side mounted radar. The Collision Warning System warns the driver of potentially dangerous situations by activating visual and audible alerts.

The Eaton VORAD Collision Warning System is intended solely as an aid for an alert and conscientious professional driver. It is not to be used or relied upon to operate the vehicle. Use this system together with rear view mirrors and other instrumentation to maintain safe operation of the vehicle. Operate a VORAD equipped vehicle in the same safe manner as if VORAD was not installed. The Eaton VORAD Collision Warning System is not a substitute for safe driving procedures nor will it compensate for any driver impairment, such as drugs, alcohol or fatigue.

The Eaton VORAD Collision Warning System may provide little or no warning for some hazards like: alerts for pedestrians, animals, oncoming vehicles and cross traffic. SmartCruise will not react to stationary objects and it does not have the capability to stop the vehicle. Failure to follow these instructions may lead to a crash resulting in severe personal injury or death.

If your vehicle is equipped with the Eaton VORAD Collision Warning System, read the manufacturer’s Driver Reference Manual before taking the vehicle on the road.

A — Pyrometer (option)

An engine pyrometer system indicates the exhaust temperature, which helps the operator get the best efficiency from the engine.

Variations in engine load can cause the exhaust temperature to vary. For example, high exhaust gas temperature is the result of prolonged engine lugging or overfueling. If the pyrometer reading shows that exhaust temperature exceeds normal, reduce fuel to the engine until exhaust temperature is reduced. Shift to a lower gear if the engine is overloaded.

W3003644

B — Engine Coolant Temperature

The gauge indicates engine coolant temperature. Normal operating temperature reading is 165 to 205 F (75 to 95 C) for the VOLVO engine. The temperature, under normal driving conditions, must be below the red sector. The temperature range for the coolant will vary depending on the type of engine, load, grade, ambient air temperature and operating conditions. If the temperature remains below or exceeds the normal temperature range, the cooling system should be checked for problems by your Volvo Truck dealer.

The LED light in the lower right corner of the gauge lights up solid when coolant temperature is excessive. The temperature limit is dependent on the engine manufacturer electronic program. Together with the gauge light, the red 1STOP telltale will come on and the buzzer will also sound. The engine is at risk and the engine controller may react by derating the engine power. Stop at the first safe place where the problem can be checked.

NOTE! If the coolant temperature returns to normal shortly after exceeding the limit and no repair has been made, the warning messages go out but there will be a fault message logged.

C — Engine Oil Pressure

The gauge indicates oil pressure by a sensor directly connected to the engine lubrication system. Normal oil pressure is 30 to 70 psi (210 to 480 kPa) when the engine is at normal operating temperature. At idle speed, the pressure may drop to 5 to 20 psi (35 to 140 kPa). When first starting a cold engine, oil pressure may exceed 90 psi (620 kPa).

The LED light in the lower right corner of the gauge lights up solid when the oil pressure is too low. The pressure limit is dependent on the engine manufacturer electronic program. When the gauge light comes on, the red 1STOP telltale starts blinking, the buzzer sounds and the oil pressure symbol appears on the graphic display. The engine is at risk and the engine controller may react by derating the engine power, for example. Bring the vehicle to a safe stop where the problem can be checked.

With very low oil pressure, the red 1STOP telltale lights up solid. The engine will shut down within 30 seconds from when the light came on. Pull off the road as soon as possible without being a safety hazard.

Failure to take necessary action when the 1STOP telltale is on, can ultimately result in automatic engine shutdown and loss of power steering assist. Vehicle crash resulting in personal injury or death can occur.

74 Instruments and Controls

3 — 1STOP Telltale

Failure to take necessary action when the 1STOP telltale is on, can ultimately result in automatic engine shutdown and loss of power steering assist. Vehicle crash resulting in personal injury or death can occur.

The 1STOP telltale lights up red to alert the operator that a severe problem has been detected and in some cases a preventive ac-

tion may be taken by the engine electronics T3008861 to protect the engine. For example: if oil

pressure or coolant level drops too low, the engine will be forced to low idle and when the vehicle speed is zero, the engine shuts down. Another example is: with excessive coolant temperature, the engine will gradually reduce power output to 50%. This telltale always activates the buzzer.

The engine may be started again after the key is turned off and then back on. However, it will only operate for 30 seconds unless the problem is resolved.

WARNING

If the problem is allowed to persist, serious damage to the engine may occur. Always repair the cause of the problem before taking the vehicle into service again.

The engine could be forced to low idle within 30 seconds from when the light came on. Pull off the road as soon as possible without being a safety hazard.

J — Master Warning Telltale

The Master Warning Telltale and buzzer alerts of a dangerous situation. Air pressure is low and the remaining air volume may not be enough for repeated braking.

The emergency brakes may engage, W3000638 causing a wheel lock-up, loss of vehicle

control and become a hazard to following vehicles. Bring the vehicle to a controled stop. Failure to follow these precautions can result in loss of braking control and serious personal injury or death can occur as a result of a vehicle accident.

This will light up when either front or rear air brake system pressure drops below 60 psi (410 kPa) or lower. The buzzer will also sound when the telltale lights up. When the pressure goes above 60 psi in both front and rear brake circuits, the telltale will automatically go out.

Air brake system pressure should be between 90 to 135 psi (620 to 930 kPa) for normal operation. The master warning telltale comes on and the buzzer sounds when air pressure has dropped to 60 psi or lower. If the air pressure is allowed to drop below 30 to 40 psi (200 to 275 kPa) in both systems, the parking spring brakes will automatically engage and stop the vehicle.

When the master warning telltale comes on and before the parking spring brakes engage, stop the vehicle in a controlled manner at an off-road location so as not to be a hazard to other vehicles on the road. Refer to page 224 for more information about the brakes.

This lights up green when the turn signal is activated and blinks in time with the outside turn signal lamps. An audible signal

also sounds in time with the telltale. A sin-

W3000903

gle short beep is heard when the telltale lights up.

5th Wheel Lock Telltale

This telltale will light up yellow when the pneumatic switch for the 5th wheel slide lock is turned on. It will stay lit until the switch is turned to the off position again. See the 5th wheel uncoupling section on page 280 for correct use.

W3000621

Wheel and Interaxle Differential Lock Telltales

These telltales will light up yellow when the pneumatic switches for either the wheel or interaxle differential lock are turned on.

For the interaxle lock, the telltale is activated by the switch. For the wheel lock, a switch in the axle turns the telltale light on only when the lock is actually engaged. It

turns the light off only when the lock is ac-

W3000904

tually disengaged. See page 258 for proper differential lock use.

Instruments and Controls 81

High Beam Telltale

Any time the high beams are activated, by the high/low beam switch or the high beam flash switch, the telltale lights up blue. For information on switching high/low beam, see page 91.

Safety Belt Telltale

The telltale lights up red each time the ignition is turned on to remind the driver to fasten the safety belt. It stays lit for 10 seconds and then goes out automatically.

Before adjusting the safety belt, make sure the vehicle is stationary and that the seat has been adjusted as required. Do not attempt to adjust the safety belt or seat while the vehicle is in motion. For proper use of the safety belt, see page 48.

Parking Brake Telltale

The telltale lights up red when the parking brake valve knob is pulled out. The daytime running light (DRL) function is also dependent on the parking brake application. Any time the parking brake telltale is on, the DRL is deactivated.

Never exit your vehicle unless the parking brake is set. Failure to do so can result in unexpected vehicle movement and cause personal injury or death.

For proper use of the parking brake, see page 229.

82 Instruments and Controls

ABS Telltale, Tractor and Trailer

The telltale lights up amber if the AntiLock Brake System (ABS) senses a problem under the following conditions:

1The system will go through its self test when the ignition switch is turned on and the telltale should continue to be on. The light should go out when the vehicle speed reaches over approximately 7 mph (11 km/h). If the telltale stays on at higher speed, there is a problem with the ABS.

2The ABS telltale lights up during driving. The ABS self test has detected a fault in the system.

The vehicle can still be driven with a problem in the ABS. However, the ABS will not be operating and standard air braking is in effect. For more information, see page 236.

The trailer ABS telltale is in effect for vehicles manufactured after January 2000.

Air Suspension Telltale

The telltale lights up amber when the suspension leveling valve is activated. As long as the switch is activated, the suspension is lower than normal and the telltale is on. For proper use of the suspension level control, see fifth wheel uncoupling on page 276.

Mirror Defroster Telltale (option)

The telltale lights up amber when the mirror defrost switch is engaged. Heater temperature is automatically regulated by an internal system in the mirror head.

N — Fuel Level Gauge

The gauge is connected to a sending unit in the fuel tank. There is only one sender even if the vehicle is equipped with dual tanks.

W3003628

O — Application Air Brake Pressure (option)

Air gauges are directly connected to the air brake system. They will indicate the brake application pressure from either the front, rear or trailer circuit pressure.

The gauge will not register air pressure until the foot brake pedal is depressed or the trailer hand brake is applied.

W3004302

O — Air Suspension Pressure (option)

Air gauges are directly connected to the air suspension system. It will indicate the suspension pressure in the air springs.

The pressure shown on the gauge is a crude indication of the load on the rear axle(s). The gauge should not be used for trying to balance the load between the axles.

W3003633

Instruments and Controls 85

P & Q — Front and Rear Brake System Air Pressures

The system air gauges are directly connected to the front and rear circuit tanks. The two gauges should register equal air pressure. Air brake system pressure should be between 90 to 135 psi (620 to 930 kPa) for normal operation. The pointers in the two gauges should register equal air pressure. By observing the gauge pointers, the operator can detect a pressure drop if an air leak develops and can readily identify the circuit affected. See page 224 for more information.

W3003637

There is a low-air warning switch in each gauge. If the pressure in a brake circuit air tank drops below approximately 60 psi (420 kPa), the red indicator in the lower right corner of the gauge will light up and the master warning indicator and the buzzer will simultaneously come on. If the air pressure is allowed to drop below 30 to 40 psi (205 to 275 kPa) in both systems, the parking brakes will automatically engage to stop the vehicle. Refer to page 224 for more information about the brakes.

Failure to observe these precautions can result in the loss of braking performance and personal injury or death can occur as a result of a vehicle crash.

Instruments and Controls 87

Traction Control System Telltale

The amber telltale will blink only when the Traction Control System (TCS) mud/snow mode is engaged. At all other times, the TCS system operates in the background without indication. The system does not have an on/off switch. See page 238 for more information.

The TCS only operates at speeds lower than 25 mph (40 km/h). The system detects wheel spin by comparing wheel speeds and controls the spin by using the brake system to transfer power to wheels with greater traction. Under circumstances where all drive wheels are spinning, the system sends a signal to the engine control unit to reduce power.

The TCS includes a TCS mud/snow switch for turning the system off to increase wheel spin. This function may be desirable in deep snow or mud to keep the vehicle from bogging down.

To operate, press in the bottom part of the switch. The switch stays in this position and the TCS telltale light blinks to indicate that the mud/snow mode is engaged. To return to normal TCS operation, press the bottom part of the switch again and it will return to rest position.

Auto Neutral Telltale

 

The Auto Neutral Telltale is for the Allison

 

WTEC III transmission. The green indica-

 

tor lights up when the transmission is in

 

auto neutral. Auto neutral is activated just

 

before the vehicle comes to a complete stop

W3004308

(less than 1.5 mph [2.5 km/h]). The gear is

 

re-engaged shortly (1–2 seconds) after the

 

brake pedal is released.

 

Allow for the gear re-engagement when ap-

 

plying throttle; do not increase engine

 

speed before the transmission has engaged.

 

If the engine speed is too high, the trans-

 

mission will not engage.

 

 

 

 

 

 

CAUTION

 

 

 

 

 

When operating the vehicle on normal

 

 

grades (less than 4%), a slight roll-back

 

 

can be experienced when the brake

 

 

pedal is released and before the trans-

 

 

mission re-engages.

 

 

 

 

 

NOTE! When operating on severe grades

 

(more than 5%), the transmission has a

 

safety feature that can be used. Before re-

 

leasing the brake pedal, manually press the

 

“DRIVE” key on the Allison gear selector,

 

and the gear is re-engaged manually to as-

 

sist in preventing roll-back.

Changing Telltale Bulbs In Cluster

NOTE! Before beginning to work, make sure the vehicle ignition is switched OFF.

If possible, adjust the steering column back. Remove the two screws at the top of the instrument cluster and fold the cluster out and let it rest face-down against the steering column so the bulbs are accessible.

CAUTION

Do not let the cluster be in the face-down position for more than maximum 15 minutes. Damage to the gauges can occur by oil running out of them, making the gauge reading inaccurate.

Do not use any tools for changing the bulbs other than the correct tool. Using a pair of pliers could easily cause a short-circuit if power is on, thereby destroying the circuit board.

W3000842

W3001306

90 Instruments and Controls

A bulb change tool is included with the ignition keys on the keychain, or can be ordered from your Volvo Truck dealer under part number 1089953. Use only this tool to change bulbs in the instrument cluster.

To remove bulb, insert tool onto the bulb assembly, rotate a 1/4 turn counterclockwise and pull the bulb assembly out of the cluster.

W3000642

Insert a new bulb into the tool and install it into the cluster. Rotate the bulb a 1/4 turn clockwise and pull the tool off of the bulb assembly.

NOTE! The telltale area in the right part of the instrument does not use all spaces for active telltales. These bulbs can be used for spare bulbs.

Lift up the instrument cluster and fasten the two screws at the top of the cluster.

Instruments and Controls 91

Steering Column Switches

Turn Signal/Headlight Beam Change

The turn signal is activated by the lever under the left side of the steering wheel. If the vehicle is equipped with a cruise control, the controls for this are located on the turn signal lever. See page 218 for more information about the cruise control.

The standard turn signal switch is not self cancelling. It must be manually returned to neutral position after making a turn. A self cancelling turn signal is available as an option.

For lane changes, the lever does not need to be moved to a locking position. Move the lever partway off the normal position until a resistance is felt. The turn signal is now activated and the lever will return to normal position when it is released.

The headlight flash function is activated by pulling the turn signal lever toward the steering wheel. The high beam will stay on until the lever is released.

To change between high and low beam, pull the lever all the way toward the steering wheel. When a slight clicking sound is heard, release the lever.

NOTE! When switching from high to low beam for oncoming traffic, release the lever as soon as the beam change is made. Holding the lever up makes the headlight flash function stay engaged.

Windshield Wiper/Washer

The wiper/washer functions are operated by the same switch. The wipers have a normal and a fast speed which are activated by moving the lever down one or two positions. To let the wipers engage for one or two passes, lightly depress the lever until the wipers start and hold it there. The wipers return to the parking position when the lever is released.

The interval wiper function is engaged by moving the lever up. The normal programmed speed is one pass every 10 seconds. To shorten the interval time, move the lever to normal wipe position and then to the interval position again when the next wiper pass is desired. In this way, the interval can be programmed between 1 to 10 seconds between each pass.

To operate the windshield washer, pull the lever toward the steering wheel. If washer fluid needs to be added, use a commercially reputable washer fluid that has good cleaning capability and does not freeze in cold weather. Total reservoir capacity is 3.3 gallons (12.5 liters).
