after the wheel rims have been cleaned
with wheel rim cleaner. Wheel rim
cleaners can lead to increased corro-
sion of the brake disks and brake pads.
Therefore, the vehicle’s brake system
should always be warmed-up before it
is parked after cleaning. To do so,
please drive your vehicle for several
minutes to allow the brakes to dry.
When applying Mercedes-Benz ap-
proved Tire Care and Mercedes-Benz
approved Wheel Care products, take
care not to spray them on the brake
disks.
!
Do not use oil or wax on these parts.
