Wash the car frequently!
Wash the car as soon as it becomes dirty, especially in the winter when
road salt and moisture can lead to corrosion.
Wash the car as follows:
·
Thoroughly hose off the dirt on the car underbody.
·
Rinse the whole car until the dirt has softened.
·
When using high pressure hose:
Ensure that the high pressure hose nozzle does not come nearer than
30 cm from the bodywork. Do not spray directly at the locks.
·
Wash with a sponge using a lot of water with or without detergent.
·
You can use lukewarm (maximum 35 °C) but not hot water.
·
If the dirt is ingrained, you can wash the car with cold degreasing
agent, but then be sure that there is a drain separator where you are
washing the car. When using cold degreasing agent, ensure that the
car is not in direct sunlight or that the paint is warm from sunlight or a
warm engine. Sunlight and heat can cause permanent damage.
Consult your Volvo workshop.
·
Dry the car with a clean, soft chamois.
·
Clean the wiper blades with a lukewarm soap solution.
Suitable detergent:
Car shampoo.
Keep in mind the following:
Always wash off bird droppings from the paintwork as fast as
possible. Bird droppings contain chemicals that affect and discolour
paintwork quickly. The discoloration cannot be polished off.

Washing
WARNING!
After washing: always test the braking so that moisture and
corrosion do not affect the brake pads and impair the brakes!
Depress the brake pedal lightly now and again when driving longer
distances in the rain or slushy snow to warm up and dry the brake
discs and pads. You should also do this when starting in very
damp or cold weather conditions.
WARNING!
Do not wash the engine when it is still warm. Fire risk!
