Driving through water
The vehicle can be driven through water up to a depth of approximately 9 in. (25 cm), at a maximum speed of 6 mph
(10 km/h).
Take particular care when driving through flowing water.
Clean the electrical connections for trailer wiring after driving in mud or water
When driving through water, maintain low speed and do not stop in the water.
WARNING
After driving through water, press lightly on the brake pedal to ensure that the brakes are functioning normally.
Water or mud can make the brake linings slippery, resulting in delayed braking effect.
CAUTION
Engine damage will occur if water is drawn into the air cleaner.
If the vehicle is driven through water deeper than 9 in (25 cm), water may enter the differential and the
transmission. This reduces the oil's lubricating capacity and may shorten the service life of these components.
Do not allow the vehicle to stand in water up to the door sills longer than absolutely necessary. This could result
in electrical malfunctions.
If the engine has been stopped while the car is in water, do not attempt to restart the engine. Have the car towed
out of the water.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, the following advice is worth noting:
Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture will reduce freeze protection.
This gives protection against freezing down to - 31°F (-35°C). See section "Coolant". The use of "recycled" antifreeze
is not approved by Volvo. Different types of antifreeze must not be mixed.
Volvo recommends using only genuine Volvo antifreeze in your vehicle's radiator. Your Volvo retailer stocks plenty
of Volvo engine coolant to help protect your vehicle during cold weather.
Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. In addition, in
extremely cold weather conditions it is worthwhile to add fuel line de -icer before refueling.
The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weather starting as
well as decreasing fuel consumption while the engine is warming up. For winter use, 5W -30 oil, particularly the
synthetic type
1, is recommended. Be sure to use good quality oil but do not use cold-weather oil for hard driving or in
warm weather. See page 231
for more information.
The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc. are used more
often. Moreover, the capacity of the battery decreases as the temperature drops. In very cold weather, a poorly charged
battery can freeze and be damaged. It is therefore advisable to check the state of
1 Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at additional charge. Please
consult your Volvo retailer.

General information
charge more frequently and spray an antirust oil on the battery posts.
ProCarManuals.com

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 age 188 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.
Before a long distance trip
It is always worthwhile to have your vehicle checked at a Volvo retailer before driving long distances. Your retailer
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 your Volvo retailer only.
Check all lights, including high beams.
Reflective warning triangles are legally required in some states/provinces.
Have a word with your Volvo retailer if you intend to drive in countries where it may be difficult to obtain the
correct fuel.
Consider your destination. If you will be driving through an area where snow or ice are likely to occur, consider
snow tires.

Exterior plastic components
Cleaning exterior plastic components should be done with a cleaning agent specially designed for this purpose.
Solvents or stain removers should not be used. Consult your Volvo retailer.
NOTE
When washing the car, remember to remove dirt from the drain holes in the doors and sills.
NOTE
During high pressure washing, the spray mouthpiece must never be closer to the vehicle than 13" (30 cm). Do not
spray into the locks.
When washing or steam cleaning the engine, avoid spraying water or steam directly on the electrical components
or toward the rear side of the engine. Special moonroof cautions:
Always close the moonroof and sun shade before washing your vehicle.
Never use abrasive cleaning agents on the moonroof.
Never use wax on the rubber seals around the moonroof
Automatic washing - simple and quick
We do NOT recommend washing your car in an automatic wash during the first six months (because the paint will not
have hardened sufficiently).
An automatic wash is a simple and quick way to clean your car, but it is worth remembering that it may not be as
thorough as when you yourself go over the car with sponge and water. Keeping the underbody clean is most important,
especially in the winter. Some
177 08 Car care
Washing and cleaning the car
automatic washers do not have facilities for washing the underbody.
CAUTION
Before driving into an automatic car wash, turn off the optional rain sensor to avoid damaging the windshield
wipers.
Make sure that side view mirrors, auxiliary lamps, etc, are secure, and that any antenna(s) are retracted or
removed. Otherwise there is risk of the machine dislodging them.
Chromed wheels : Clean chrome-plated wheels using the same detergents used for the body of the vehicle.
Aggressive wheel-cleaning agents can permanently stain chrome-plated wheels
WARNING
When the car is driven immediately after being washed, apply the brakes several times in order to remove any
moisture from the brake linings.
Engine cleaning agents should not be used when the engine is warm. This constitutes a fire risk.
Exterior lighting
Condensation may form temporarily on the inside of the lenses of exterior lights such as headlights, fog lights, or
taillights. This is normal and the lights are designed to withstand moisture. Normally, condensation will dissipate after
the lights have been on for a short time.
ProCarManuals.com

Clean the windshield, windshield wipers, headlights, and taillights
Monthly:
Check cold tire pressure in all tires. Inspect the tires for wear.
Check that engine coolant and other fluid levels are between the indicated "min" and "max" markings.
Clean interior glass surfaces with a glass cleaner and soft paper towels.
Wipe driver information displays with a soft cloth.
Visually inspect battery terminals for corrosion. Corrosion may indicate a loose terminal connector, or a battery near the
end of its useful service life. Consult your Volvo retailer for additional information.
As needed:
Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup of dirt, and corrosion that can
be caused by salt residues.
Clean leaves and twigs from air intake vents at the base of the windshield, and from other places where they may
collect.

Maintaining your car
Emission inspection readiness
What is an Onboard Diagnostic System (OBD II)?
OBD II is part of your vehicle's computerized engine management system. It stores diagnostic information about your
vehicle's emission controls. It can light the Check Engine light (MIL) if it detects an emission control "fault." A "fault" is a
component or system that is not performing within an expected range. A fault may be permanent or temporary. OBD II
will store a message about any fault.
How Do States Use OBD II for Emission Inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector can then read "faults." In some states,
this type of inspection has replaced the tailpipe emission test.
How Can My Vehicle Fail OBD II Emission Inspection ?
Your vehicle can fail OBD II emission inspection for any of the following reasons.
If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
If your vehicle's Check Engine light was lit, but went out without any action on your part, OBD II will still have a
recorded fault. Your vehicle may pass or fail, depending on the inspection practices in your area.
If you had recent service that required disconnecting the battery, OBD II diagnostic information may be incomplete and
"not ready" for inspection. A vehicle that is not ready may fail inspection.
How Can I Prepare for My Next OBD II Emission Inspection ?
If your Check Engine (MIL) light is lit - or was lit but went out without service, have your vehicle diagnosed and, if
necessary, serviced by a qualified Volvo technician.
If you recently had service for a lit Check Engine light, or if you had service that required disconnecting the battery, a
period of driving is necessary to bring the OBD II system to "ready" for inspection. A half-hour trip of mixed stop-and -
go/highway driving is typically needed to allow OBD II to reach readiness. Your Volvo retailer can provide you with more
