8 Introduction
Important warnings
Accessory Installation
We strongly recommend that Volvo owners install only genuine, Volvo-approved accessories, and that accessory
installations be performed only by a trained and qualified Volvo service technician.
Genuine Volvo accessories are tested to ensure compatibility with the performance, safety, and emission systems in
your car. Additionally, a trained and qualified Volvo service technician knows where accessories may and may not be
safely installed in your Volvo. In all cases, please consult a trained and qualified Volvo service technician before
installing any accessory in or on your car.
Accessories that have not been approved by Volvo may or may not be specifically tested for compatibility with your
car. Additionally, an inexperienced installer may not be familiar with some of your car's systems.
Any of your car's performance and safety systems could be adversely affected if you install accessories that Volvo
has not tested, or if you allow accessories to be installed by someone unfamiliar with your car.
Damage caused by unapproved or improperly installed accessories may not be covered by your new car warranty.
See your Warranty and Service Records Information booklet for more warranty information. Volvo assumes no
responsibility for death, injury, or expenses that may result from the installation of non-genuine accessories.
Driver distraction
Driver distraction results from driver activities that are not directly related to controlling the car in the driving
environment. Your new Volvo is, or can be, equipped with many feature-rich entertainment and communication
systems. These include hands-free cellular telephones, navigation systems, and multipurpose audio systems. You may
also own other portable electronic devices for your own convenience. When used properly and safely, they enrich the

Observe the following rules:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
Whenever possible, avoid using the vehicle for driving short distances. This does not allow the engine to reach
normal operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Use the transmission's Drive ( D) position as often as possible and avoid using kickdown.
Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the vehicle.
Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
Remove snow tires when threat of snow or ice has ended.
At highway driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed
than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment Some of the above mentioned items and others are checked at the standard
maintenance intervals.
Avoid overheating the engine
Do not drive at engine speeds above 4,500 rpm if you tow a trailer in hilly areas. This could cause the engine oil to
overheat.
WARNING
Driving with the trunk open : Driving with the trunk open could lead to poisonous exhaust gases entering the
passenger compartment. If the trunk must be kept open for any reason, proceed as follows:
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its
highest setting.
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load in the cargo
area, the less the tendency to understeer.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore,
133 06 Starting and driving
General information
check that the tires are inflated to the recommended pressure according to the vehicle load. See the "Tire pressure"
ProCarManuals.com

charge more frequently and spray an antirust oil on the battery posts.
Volvo recommends the use of snow tires on all four wheels for winter driving - see the chapter "Wheels and tires."
To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see page 211 for the
location of the washer fluid reservoir). This is important since dirt is often splashed on the windshield during winter
driving, requiring the frequent use of the washers and wipers. Volvo Washer Solvent should be diluted as follows:
Down to 14° F (-10° C): 1 part washer solvent and 4 parts water Down to 5° F (-15° C): 1 part washer solvent and 3
parts water Down to 0° F (-18° C): 1 part washer solvent and 2 parts water Down to -18° F (-28° C): 1 part washer
solvent and 1 part water.
Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid using de -icing sprays as they can cause damage to the locks.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
When the engine is not running, avoid turning the ignition key to position II. Many electrical systems (the audio
system, the optional navigation system, power windows, etc) will function with the ignition key in position I. This
position reduces drain on the battery.
Please keep in mind that using systems, accessories, etc that consume a great deal of current when the engine is not
running could result in the battery being completely drained.
The optional 12 volt socket in the cargo area provides electrical current even with the ignition switched off, which
drains the battery.
NOTE
If the ignition is switched on, a warning message will be displayed in the text window in the instrument panel
when the battery charge is low.
An energy conserving function designed into the vehicle's electrical system will switch off certain functions or
reduce the load on the battery by, e.g., reducing the audio system's volume.
135 06 Starting and driving
General information
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo service technician before
driving long distances. Your retailer or service technician will also be able to supply you with bulbs, fuses, spark plugs
and wiper blades for your use in the event that problems occur.
As a minimum, the following items should be checked before any long trip:
Check that engine runs smoothly and that fuel consumption is normal.
Check for fuel, oil, and fluid leakage
Have the transmission oil level checked1.
Check condition of drive belts.
Check state of the battery's charge.
Examine tires carefully (the spare tire as well), and replace those that are worn. Check tire pressures.
The brakes, front wheel alignment, and steering gear should be checked by a trained and qualified Volvo service
ProCarManuals.com

Batteries generate hydrogen gas, which is flammable and explosive.
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces. If
contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.
Never expose the battery to open flame or electric spark.
Do not smoke near the battery.
Failure to follow the instructions for jump starting can lead to personal injury.
Do not touch the jumper cables during the attempt to start the vehicle. This could cause sparks.
155 06 Starting and driving
Towing a trailer
General information
Volvo recommends the use of Volvo trailer hitches that are specially designed for the vehicle.
Maximum trailer weights recommended by Volvo are:
Trailers without brakes : 1,540 lbs (700 kg).
Trailers with brakes: 2,000 lbs (900 kg) Observe the legal requirements of the state/province in which the vehicles
are registered.
The maximum recommended hitch tongue load is 165 lbs ( 75 kg).
All Volvo models are equipped with energy-absorbing shock-mounted bumpers. Trailer hitch installation should not
interfere with the proper operation of this bumper system.
Trailer towing does not normally present any particular problems, but take into consideration:
Increase tire pressure to recommended full. See the chapter "Wheels and tires."
When your vehicle is new, avoid towing heavy trailers during the first 620 miles (1,000 km).
Maximum speed when towing a trailer: 50 m.p.h. (80 km/h).
Engine and transmission are subject to increased loads. Therefore, engine coolant temperature should be closely
watched when driving in hot climates or hilly terrain. Use a lower gear and turn off the air conditioner if the
temperature gauge needle enters the red range.
If the automatic transmission begins to overheat, a message will be displayed in the information display.
Avoid overload and other abusive operation.
Hauling a trailer affects handling, durability, and economy.
It is necessary to balance trailer brakes with the towing vehicle brakes to provide a safe stop (check and observe
state/local regulations).
Do not connect the trailer's brake system directly to the vehicle's brake system.
More frequent vehicle maintenance is required.
Remove the ball and drawbar assembly when the hitch is not being used.
Volvo recommends the use of synthetic engine oil when towing a trailer over long distances or in mountainous
areas.
WARNING
Bumper-attached trailer hitches must not be used on Volvos, nor should safety chains be attached to the bumper.
Trailer hitches attaching to the vehicle's rear axle must not be used.
Never connect a trailer's hydraulic brake system directly to the vehicle brake system, nor a trailer's lighting system
directly to the vehicle lighting system. Consult your nearest trained and qualified Volvo service technician for correct
installation.
When towing a trailer, the trailer's safety wire must be correctly fastened to the hole or hook provided in the

General information
Your vehicle is equipped with tires according to the vehicle's tire information placard on the B-pillar (the structural
member at the side of the vehicle, at the rear of the driver's door opening), or on the inside of the fuel filler door on
Canadian models.
The tires have good road holding characteristics and offer good handling on dry and wet surfaces. It should be noted
however that the tires have been developed to give these features on snow/ice-free surfaces.
Certain models are equipped with "all-season" tires, which provide a somewhat higher degree of road holding on
slippery surfaces than tires without the "all-season" rating. However, for optimum road holding on icy or snow-
ProCarManuals.com

covered roads, we recommend suitable winter tires on all four wheels.
When replacing tires, be sure that the new tires are the same size designation, type (radial) and preferably from the
same manufacturer, on all four wheels. Otherwise there is a risk of altering the car's roadholding and handling
characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be suspended off the floor or placed on their sides
on the floor.
Tires not mounted on rims should be stored on their sides or standing upright, but should not be suspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never be stored in close proximity to
solvents, gasoline, oils, etc.
WARNING
The wheel and tire sizes for your Volvo are specified to meet stringent stability and handling requirements.
Unapproved wheel/tire size combinations can negatively affect your vehicle's stability and handling. Approved tire
sizes are shown in the Tire inflation pressure tables on pages 172 and 173
.
Any damage caused by installation of unapproved wheel/tire size combinations will not be covered by your new
vehicle warranty. Volvo assumes no responsibility for death, injury, or expenses that may result from such
installations.
Tread wear indicator
The tires have wear indicator strips running across or parallel to the tread. The letters TWI are printed on the side of
the tire. When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire
should be replaced. Tires with less than 1/16" (1.6 mm) tread offer very poor traction.
When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being
replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the
vehicle.

New Tires
Remember that tires are perishable goods. As of 2000, the manufacturing week and year (Department of
Transportation (DOT) stamp) will be indicated with 4 digits (e.g. 1502 means that the tire illustrated was manufactured
during week 15 of 2002).
Tire age
Tires degrade over time, even when they are not being used. It is recommended that tires generally be replaced after 6
years of normal service. Heat caused by hot climates, frequent high loading conditions or Ultra Violet (U.V) exposure
can accelerate the aging process.
You should replace the spare tire when you replace the other road tires due to the aging of the spare.
A tire's age can be determined by the DOT stamp on the sidewall (see the illustration).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
Improving tire economy
Maintain correct tire pressure. See the tire pressure tables on pages 172 and 173.
Drive smoothly: avoid fast starts, hard braking and tire screeching.
Tire wear increases with speed.
Correct front wheel alignment is very important.
Unbalanced wheels impair tire economy and driving comfort.
Tires must maintain the same direction of rotation throughout their lifetime.
When replacing tires, the tires with the most tread should be mounted on the rear wheels to reduce the chance of
oversteer during hard braking.
Hitting curbs or potholes can damage the tires and/or wheels permanently.

Tire inflation
Tire inflation
Check tire inflation pressure regularly.
ProCarManuals.com

Tables listing the recommended inflation pressure for your vehicle can be found on pages 172 and 173. A tire inflation
pressure placard is also located on the driver's side Bpillar (the structural member at the side of the vehicle, at the rear
of the driver's door opening). This placard indicates the designation of the factory-mounted tires on your vehicle, as
well as load limits and inflation pressure.
NOTE
The placards shown indicate inflation pressure for the tires installed on the car at the factory only.
Use a tire gauge to check the tire inflation pressure, including the spare, at least once a month and before long trips.
You are strongly urged to buy a reliable tire pressure gauge, as automatic service station gauges may be inaccurate.
Use the recommended cold inflation pressure for optimum tire performance and wear.
Under-inflation or over-inflation may cause uneven treadwear patterns.
WARNING
Under-inflation is the most common cause of tire failure and may result in severe tire cracking, tread separation,
or "blowout," with unexpected loss of vehicle control and increased risk of injury.
Under-inflated tires reduce the load carrying capacity of your vehicle.
When weather temperature changes occur, tire inflation pressures also change. A 10-degree temperature drop causes a
corresponding drop of 1 psi (7 kPa) in inflation pressure. Check your tire pressures frequently and adjust them to the
proper pressure, which can be found on the vehicle's tire information placard or certification label.
Checking tire pressure
Cold tires
Inflation pressure should be checked when the tires are cold.
The tires are considered to be cold when they have the same temperature as the surrounding (ambient) air.
This temperature is normally reached after the car has been parked for at least 3 hours.
171 07 Wheels and tires
Tire inflation
After driving a distance of approximately 1 mile ( 1.6 km), the tires are considered to be hot. If you have to drive
farther than this distance to pump your tire(s), check and record the tire pressure first and add the appropriate air
ProCarManuals.com

pressure when you get to the pump.
If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tires are hot from driving and it
is normal for pressures to increase above recommended cold pressures. A hot tire at or below recommended cold
inflation pressure could be significantly under-inflated.
To check inflation pressure
1. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve.
2. Add air to reach the recommended air pressure
3. Replace the valve cap.
4. Repeat this procedure for each tire, including the spare.
5. Visually inspect the tires to make sure there are no nails or other objects embedded that could puncture the tire and
cause an air leak.
6. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.
NOTE
If you overfill the tire, release air by pushing on the metal stem in the center of the valve. Then recheck the
pressure with your tire gauge.
Some spare tires require higher inflation pressure than the other tires. Consult the tire inflation tables on pages 172
and 173 or see the inflation pressure placard.
