Replacing High Beam headlight

bulbs

On models with halogen headlights, the High
Beam headlight bulb can be replaced by the
owner.

Before the bulb can be accessed, the headlight
housing's rectangular cover must be removed,
see the article "Removing the rectangular head-
light cover."

CAUTION

Never touch the glass of bulbs with your fin-
gers. Grease and oils from your fingers vapor-
ize in the heat and will leave a deposit on the
reflector, which will damage it.

Driver's side bulb housing shown

1. Remove the bulb by turning the bulb holder

upward and then pulling it straight out.

2. Carefully pry the plastic sleeve by the con-

nector's locking lug to release it.

Refilling coolant

Coolant helps keep the gasoline engine at the
proper operating temperature. The heat transfer-
red from the engine to the coolant can be used
to warm the passenger compartment.

When refilling coolant, follow the instructions on
the package and use the recommended amount
of coolant. Never fill the cooling system with
water only; this could lead to freezing, corrosion
and engine damage.

WARNING

If the engine has been running, the coolant
will be very hot. Allow the engine to cool
before opening the coolant expansion tank. If
this is not possible, open the cap very slowly
to allow pressure to dissipate.

Coolant expansion tank

Lift the rubber strip by pressing it inward in
the engine compartment.

Remove the plastic cover by folding out the
catch and lifting the cover upward.

Unscrew the expansion tank cap and add
coolant. The level should be between the
MIN and MAX marks on the tank.

Put the other components back in place in the
reverse order.

CAUTION

•

High levels of chlorine, chlorides and
other salts may cause corrosion in the
cooling system.

•

Only use coolants with corrosion protec-
tion recommended by Volvo.

•

The ratio of coolant to water is 50/50.

•

Mix the coolant with tap water of drinka-
ble quality.

•

If maintenance is performed on the cool-
ing system or if the coolant is replaced,
flush the cooling system with clean water
before adding new a new coolant/water
mixture.

•

The engine may only be operated with a
properly filled cooling system. Otherwise,
high temperatures and cracks in the cyl-
inders may occur.

Refilling the windshield washer fluid

reservoir

Washer fluid helps keep the windshield and
headlights clean.

The windshield and headlight washers

* share a

common reservoir. Open the blue cap to refill
washer fluid (see the illustration for the location
of the reservoir).

During cold weather, the reservoir should be filled
with windshield washer solvent containing anti-
freeze. Use Volvo Original Washer Fluid or the
equivalent with a recommended pH value
between 6 and 8 in a 1:1 solution.

When there is approx. 1 qt (1 liter) of washer
fluid remaining in the reservoir, a text message
and the 

 symbol will be displayed in the

instrument panel.

Cleaning the exterior

The vehicle should be washed at regular inter-
vals 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.

Hand washing

The following points should be kept in mind when
washing and cleaning the car:

CAUTION

Avoid using car washing detergents with a pH
value lower than 3.5 or higher than 11.5.
Doing so could result in discoloring of ano-
dized aluminum surfaces on e.g., roof rails or
the frames around the side windows.

•

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 car washing detergent can be used to
facilitate the softening of dirt and oil.

||

MAINTENANCE AND SERVICING

548

•

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 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 fre-
quent washing is recommended.

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.

•

Dirt, snow, etc., on the headlights can
reduce lighting capacity considerably.
Clean the headlights regularly, for exam-
ple when refueling.

Special laminated panoramic roof cau-
tions:

•

Always close the laminated panoramic
roof and sun shade before washing your
vehicle.

•

Never use abrasive cleaning agents on
the laminated panoramic roof.

•

Never use wax on the rubber seals
around the laminated panoramic roof.

NOTE

When washing the car, remember to remove
dirt from the drain holes in the doors and sills.

Automatic car washes

•

We do NOT recommend washing your car in
an automatic wash during the first few

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.

NOTE

Condensation may form temporarily on the
inside of the lenses of exterior lights such as
headlights 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.

MAINTENANCE AND SERVICING

549

CAUTION

When using an automatic car wash in which
the vehicle has to be able to roll freely, the
auto-hold brake function must be deactivated.
If this is not done, the brakes will automati-
cally be applied when the vehicle is stationary.

To deactivate this function:

1. Drive the vehicle into the car wash
2. Turn off the auto-hold function using the

control on the center console

3. Turn off the parking brake's automatic

function in the center display's Top view
(tap 

Settings

, tap 

My Car

Electric

Parking Brake

 and deselect 

Auto

Activate Parking Brake

)

4. Put the gear selector in N
5. Switch off the ignition by turning the start

knob to STOP and holding it in this posi-
tion for at least 4 seconds

The vehicle will then be able to roll freely.

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. Oth-
erwise there is risk of the machine dis-
lodging 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 con-
stitutes a fire risk.

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 exte-

rior of your vehicle. The instructions for using
these products should be followed carefully. Sol-
vents or stain removers should not be used.

CAUTION

•

Avoid waxing or polishing plastic or rub-
ber components

•

Polishing chromed strips can wear away
or damage the surface

•

Polishes containing abrasive substances
should not be used
