Replacing wiper
blades
Lift the wiper arm off
the windshield and hold
blade at right angles to
arm. Pinch the end of
the plastic clip located
at the back of the arm.
Slide the wiper blade
along the arm to release
it from the hook.
Install new blade
(installation is the
reverse of removal) and
make sure that it is
properly attached to the
wiper arm.
For reasons of safety,
you should change the
windshield wiper blades
as soon as they start to
leave marks on the
windshield or fail to
wipe efficiently and
cleanly.
To obtain maximum
lifetime from a set of
wiper blades, clean
them with a stiff-bristle
brush and warm, soapy
water as part of a
normal car wash.
Replacing headlight
wiper blades (certain
models)
Pull the wiper blade in the
direction indicated by the arrow
in the illustration to remove it.
Press the new blade into place.
Check that the new blade is
properly attached to the wiper
arm.

Paint touch-up
Paint damage requires
immediate attention to avoid
rusting. Make it a habit to check
the finish regularly; when
washing the car for instance.
Touch up if necessary.
Paint repairs require special
equipment and skill. Contact
your Volvo retailer for any
extensive damages.
Minor scratches can be repaired
by using Volvo touch-up paint.
NOTE: When ordering touch-
up paint from your Volvo
retailer, use the paint code
indicated on the model plate.
The plate is located on the panel
above the right-side head lights. Minor stone chips and
scratches
Material:
Primer - can
Paint - touch-up bottle
Brush
Masking tape
Scars on the surface
If the stone chip has not
penetrated down to the metal
and an undamaged layer of paint
remains, the touch-up paint can
be applied as soon as the spot
has been cleaned. Deep scars
If the stone chip has been
penetrated down to the metal,
proceed as follows:
1 Place a strip of masking tape
over the damaged surface. Pull
the tape off so that any loose
flakes of paint adhere to it
Thoroughly mix the primer and
apply it with a small brush.
When the primer surface is dry,
the paint can be applied using a
brush.
Mix the paint thoroughly: apply
several thin paint coats and let
dry each application.
3 If there is a longer scratch, you
may want to protect surrounding
paint by masking it off.
NOTE: When touching up the
car, it should be cleaned and dry.
The surface temperature should
be above 60°F (+15°C).
Washing the car pg. 100
Washing
l The car should be washed at
regular intervals since dirt, dust,
insects and tar spots adhere to the
paint and may cause damage.
NOTE: It is particularly important
to wash the car frequently in the
wintertime to prevent corrosion,
when salt has been used on the
roads.
l When washing the car, do not
expose it to direct sunlight. Use
lukewarm water to soften the dirt
before you wash with a sponge, and
l After cleaning the engine, the spark plug wells should be
inspected for water and blown dry if necessary.
Suitable detergents
Special car washing detergents or liquid dishwashing detergent
can be used. A suitable mixture is about 2.5 fl. oz. (8.5 cl) of
detergent to 2.6 US gal. (10 liters) of warm water. After
washing with a detergent the car should be well rinsed with
clean water.

Volvo recommends that the
timing belt be replaced every
70,000 miles (112,000 km).
PCV system
The orifice nipple in the intake
manifold and the filter at the
end of the PCV hose in the
aircleaner should be inspected
every 60,000 miles (96,000 km).
Check/replace rubber hoses at
the same time.
and use correct torque, see

good condition. Cracked or
damaged connectors should be
replaced.
When changing the spark plugs,
clean the terminals and the
rubber seals.
Battery maintenance pg. 111
Battery maintenance
Driving habits and conditions, climate, the
number of starts, etc. all affect the service life and
function of the battery. In order for your battery to
perform satisfactorily, keep the following in mind:
l Check the fluid level in the battery every 6
months or every 10,000 * miles (16,000 km).
The fluid level in each battery cell should be
checked - use a screw driver to open the caps and
a flashlight to inspect the level.
*More frequently in warm climates.
l If necessary, add distilled water to
approximately 0.4 in. (10 mm) above the plates in
the cell or to the level indicator. See the
illustrations above.
l Check that the battery cables are correctly
connected and properly tightened.
l Never disconnect the battery when the engine is
running, for example when changing the battery.
l The battery should be disconnected when a
boost charger is used.
l Switch off the radio before disconnecting the
battery. If your radio has an antitheft code and the
battery is disconnected, the radio code has to be
reentered in order for the radio to function.
