Fluids
Coolant
Normally, the coolant does not need to be changed. If the system must be drained, consult a trained and qualified
Volvo service technician.
See page 279
for information on cooling system capacities.
CAUTION
Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has a
lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water and antifreeze).
The cooling system must always be kept filled to the correct level, and the level must be between the MIN and
MAX marks. If it is not kept filled, there can be high local temperatures in the engine which could result in damage.
Different types of antifreeze/coolant may not be mixed. Check coolant regularly.
WARNING
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools.
If it is necessary to top off the coolant when the engine is warm, unscrew the expansion tank cap slowly so that
the overpressure dissipates.

Fuses
Replacing fuses
There are relay/fuse boxes located in the engine compartment, the passenger compartment, and the cargo area.
If an electrical component fails to function, this may be due to a blown fuse. The easiest way to see if a fuse is blown
is to remove it.
To do so:
1. Pull the fuse straight out. If a fuse is difficult to remove, special fuse removal tools are located on the inside of the
fuse box covers.
2. From the side, examine the curved metal wire in the fuse to see if it is intact.
If the wire is broken, insert a new fuse of the same color and amperage (written on the fuse).
If fuses burn out repeatedly, have the electrical system inspected by a trained and qualified Volvo service technician.
WARNING
Never use metal objects or fuses with higher amperage than those stated on the following pages. Doing so could
seriously damage or overload the vehicle's electrical system.

Washing the car
WARNING
Be sure that the compressor is not connected to a 12-volt socket while replacing the container.
The following points should be kept in mind when washing and cleaning the car:
The car should be washed at regular intervals since dirt, dust, insects and tar spots adhere to the paint and may cause
damage. To help prevent corrosion, it is particularly important to wash the car frequently in the wintertime.
Avoid washing your car in direct sunlight. Doing so may cause detergents and wax to dry out and become abrasive.
To avoid scratching, use lukewarm water to soften the dirt before you wash with a soft sponge, and plenty of sudsy
water.
Bird droppings : Remove from paintwork as soon as possible. Otherwise the finish may be permanently damaged.
A detergent can be used to facilitate the softening of dirt and oil.
A water-soluble grease solvent may be used in cases of sticky dirt. However, use a wash place equipped with a
drainage separator.
Dry the car with a clean chamois and remember to clean the drain holes in the doors and rocker panels.
Tar spots can be removed with kerosene or tar remover after the car has been washed.
A stiff-bristle brush and lukewarm soapy water can be used to clean the wiper blades. Frequent cleaning of the
windshield and wiper blades improves visibility considerably and also helps prolong the service life of the wiper
blades.
Wash off the dirt from the underside (wheel housings, fenders, etc).
In areas of high industrial fallout, more frequent washing is recommended.
After cleaning the engine, the spark plug wells should be inspected for water and blown dry if necessary.
NOTE
When washing the car, remember to remove dirt from the drain holes in the doors and sills.
CAUTION
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.
Dirt, snow, etc., on the headlights can reduce lighting capacity considerably. Clean the headlights regularly, for
example when refueling
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.
Exterior components
Volvo recommends the use of special cleaning products, available at your Volvo retailer, for cleaning colored plastic,
rubber, or ornamental components such as chromed strips on the exterior of your vehicle. The instructions for using
these products should be followed
266 06 Maintenance and specifications

carefully. Solvents or stain removers should not be used.
CAUTION
Avoid waxing or polishing plastic or rubber components
Polishing chromed strips can wear away or damage the surface
Polishes containing abrasive substances should not be used
Automatic car wash
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 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 vehicle is driven immediately after being washed, apply the brakes, including the parking brake, 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.
267 06 Maintenance and specifications
Vehicle care
Polishing and waxing
Normally, polishing is not required during the first year after delivery, however, waxing may be beneficial.
Before applying polish or wax the vehicle must be washed and dried. Tar spots can be removed with kerosene or tar
remover. Difficult spots may require a fine rubbing compound.
After polishing use liquid or paste wax.
Several commercially available products contain both polish and wax.
Waxing alone does not substitute for polishing a dull surface.
A wide range of polymer-based waxes can be purchased today. These waxes are easy to use and produce a long-
lasting, high-gloss finish that protects the bodywork against oxidation, road dirt and fading.
Do not polish or wax your vehicle in direct sunlight (the surface of the vehicle should not be warmer than 113° F
