i
After running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 326). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.
When leaving the car wash, make sure that the
mirrors are folded out. Otherwise they may vi-
brate.
!
Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings may
have chrome appearance, they could be made of
anodized aluminum that will be damaged when
cleaned with chrome cleaner. Instead, use damp
cloth to clean those ornamental moldings.
Very dirty ornamental moldings of which you are
sure are chrome-plated, use a chrome cleaner. If
in doubt whether an ornamental molding is
chrome-plated, contact an authorized
Mercedes-Benz Center.
!
Only use window cleaning solutions that are
suitable for plastic lamp lenses. Window clean-
ing solutions which are not suitable may damage
the plastic lamp lenses of the headlamps. There-
fore, do not use abrasives, solvents or cleaners
that contain solvents.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry
cloth or sponge.
Otherwise you may scratch or damage the lens
surface.
