221Vehicle maintenance and cleaning
Use an industrial cleaner to remove brake dust. Any damage to the paint on
steel wheel rims should be repaired before starting to rust.
WARNING
●Never wash tyres with a cylindrical jet. Even at large spraying distan-
ces and short cleaning times, visible and invisible damage can occur to
the tyres. This may cause an accident.
●Water, ice and salt on the brakes can reduce braking efficiency. Risk
of accident. Directly after washing, avoid sudden and sharp braking.
“Dry” the brakes by braking several times ⇒ page 201.
Alloy wheel rims
Every two weeks
–Wash salt and brake dust from alloy wheels.
–Use an acid free detergent to clean the wheel rims.
Every three months
–Apply a hard wax compound to the wheels.
Alloy wheels require regular attention to preserve their appearance. If road
salt and brake dust are not often removed, the aluminium finish will be im-
paired.
Always use an acid-free detergent for alloy wheel rims.
Car polish or other abrasive agents should not be used. If the protective
coating is damaged, e.g. by flying stones, the damaged area should be re-
paired immediately.

Underbody protection
The vehicle underbody is coated to protect it from chemical
and mechanical damage.
The protective coating can be damaged when driving. We recommend you
to check the protective coating under the body and on the running gear, and
reinstated if necessary, before and after the winter season.
We recommend you to go to your Technical Service to carry out repair work
and additional anti-corrosion work.
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite. Risk of fire.
