371 Operation
Vehicle care
Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a damp cloth.Headlamps, tail lamps, side markers,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham-
poo, with plenty of water.
!
Make sure that the windshield wiper switch
is set toM (
page 58). Otherwise, e.g. the
rain sensor could activate and cause the wipers
to move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent dam-
age to the mirrors.
i
After running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 372) and the wiper blade inserts
(
page 372). This will prevent smears and re-
duce wiping noise which can be caused by resid-
ual 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 clean-
er. 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.

Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham-
poo, with plenty of water and a
non-scratching cloth to clean sensor

Restart the engine after cleaning sen-
sor cover1.
Cleaning the windows and the wiper
blades
Make sure the hood is fully closed.
Switch on the ignition (

Turn combination switch to wiper
settingu (
page 58).
With wiper arms in vertical position,
switch off the ignition (
page 63).
Fold the wiper arms forward until they
snap into place.
Clean the wiper blade inserts with a
clean cloth and detergent solution.
Use a soft, clean cloth and a mild win-
dow cleaning solution on all outside
and inside glass surfaces.
An automotive glass cleaner is recom-
mended.
!
To prevent scratches or damage, never ap-
ply strong force and only use a soft, non-scratch-
ing cloth when cleaning the sensor cover1. Do
not attempt to wipe dirty sensors with a dry cloth
or sponge.
!
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 re-
move SmartKey from starter switch (vehi-
cles with KEYLESS-GO*: Make sure the
vehicle’s on-board electronics have
status0) before cleaning the windshield
and/or the wiper blades. Otherwise, the
wiper motor could suddenly turn on and
cause injury.!
Do not pull on the wiper blade inserts. They
could tear.

For safety reasons, switch off wipers and re-
move SmartKey from starter switch (vehi-
cles with KEYLESS-GO*: Make sure the
vehicle’s on-board electronics have

Otherwise, the wiper motor could suddenly
turn on and cause injury.Warning!
G
Wiper blades are components that are sub-
ject to wear and tear. Change the wiper
blades twice a year, preferably in the spring
and fall. Otherwise the windows will not be
properly wiped. As a result, you may not be
able to observe surrounding traffic condi-
tions and could cause an accident.
!
To avoid damage to the hood:
The wiper arms should only be folded for-
ward when in the vertical position.
Never open the hood when the wiper arm is
folded forward.
!
Hold on to the wiper when folding the wiper
arm back. If released, the force of the impact
from the tensioning spring could crack the wind-
shield.
Do not allow the wiper arms to contact the wind-
shield glass without a wiper blade inserted.
Make sure the wiper blades are properly in-
stalled. Improperly installed wiper blades may
cause windshield damage.
For your convenience, we recommend that you
have this work carried out by an authorized
Mercedes-Benz Center.
