blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Do not use acidic wheel cleaning productsto remove brake dust. This could damagewheel bolts and brake components.
!Do not park your vehicle for a long period oftime directly after cleaning, particularly aftercleaning the wheel rim with wheel cleaner.Wheel cleaner can lead to the increased cor-rosion of the brake discs and pads. Therefore,drive for a few minutes after cleaning. Byheating up the brakes, the brake discs andpads dry. The vehicle can then be parked for along period of time.
