MAINTENANCE AND SERVICE
||
If necessary, use cold degreasing agent on
•
very dirty surfaces. Note that in this case,
the surfaces must not be hot from the sun.
Wash using a sponge, car shampoo and
•
plenty of lukewarm water.
Clean the wiper blades with a lukewarm
•
soap solution or car shampoo.
Dry the car using a clean, soft chamois or
•
a water scraper. If you avoid allowing
drops of water to dry in strong sunlight,
you reduce the risk of water drying stains
which may need to be polished out.
After the car has been washed, tar from
•
asphalt may remain. Use tar remover that
is recommended by Volvo to get rid of the
last spots.
WARNING
Always have the engine cleaned by a work-
shop. There is a risk of fire if the engine is
hot.
IMPORTANT
Dirty headlamps have impaired functional-
ity. Clean them regularly, e.g. when refuel-
ling.
Do not use any corrosive cleaning agents
but use water and a non-scratching
sponge instead.

NOTE
Outside lighting such as headlamps and
rear lamps may temporarily have conden-
sation on the inside of the lens. This is nor-
mal, all exterior lighting is designed to
withstand this. Condensation is normally
vented out of the lamp housing when the
lamp has been switched on for a time.
IMPORTANT
Make sure that the sunroof* and sun
•
visor are closed before washing the
car.
Never use polishing agent with abra-
•
sive properties on the sunroof.
Never use wax on the rubber mould-
•
ings around the sunroof.
IMPORTANT
Remember to remove dirt from the drain
holes in the doors and in the sills after
washing the car.
