Vehicle care
Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.Headlamps, tail lamps, side makers,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water.Cleaning the windows and the wiper
blades
Make sure the hood is fully closed.
Switch on the ignition (page 37).
Turn combination switch to wiper
settingII (
page 56).
With wiper arms in vertical position,
switch off the ignition (
page 37).
iAfter running the vehicle through an
automatic car wash, wipe any wax off of the
windshield (
page 343). 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
vibrate.
!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 a
damp cloth to clean those ornamental moldings.
For very dirty ornamental moldings of which
you are sure are chrome-plated, use a chrome
cleaner. If in doubt whether an ornamental mold-
ing is chrome-plated, contact an authorized
Mercedes-Benz Center.
!Only use window cleaners that are suitable
for plastic lamp lenses. Window cleaning solu-
tions which are not suitable may damage the
plastic lamp lenses of the headlamps. Therefore,
do not use abrasives, solvents or cleaners that
contain solvents.
Never apply strong force and use only a soft,
non-scratchy 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.
!The windshield wipers must be in a vertical
position before folding them away from the wind-
shield. They could otherwise damage the hood.
Never open the hood when the wiper arms are
folded forward.
Warning!G
For safety reasons, switch off wipers and
remove SmartKey from starter switch be-
fore cleaning the windshield and/or the wip-
er blades. Otherwise, the wiper motor could
suddenly turn on and cause injury.
