When taking the vehicle through an
automatic conveyor-type car wash:
Make sure the automatic transmission
remains in neutral position N. Observe
instructions, see “Remaining in neutral
position N” (Y page 292).
When leaving the automatic car wash, make
sure the mirrors are folded out.
After running the vehicle through an
automatic car wash, wipe any wax off of the
windshield and the wiper blade inserts. This
will prevent smears and reduce wiping noise
which can be caused by residual wax on the
windshield.
Ornamental moldings X
For regular cleaning and care of ornamental
moldings, use a damp cloth.
! 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 molding is chrome-plated,
contact an authorized Mercedes-Benz
Center.
Headlamps, brake lamps, tail lamps,
side markers, turn signal lenses X
Use a mild vehicle wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
! Only use window cleaning solutions that
are suitable for plastic lamp lenses.
Window cleaning solutions which are not
suitable may damage the plastic lamp
lenses of the headlamps. Therefore, do not
use abrasives, solvents or cleaners that
contain solvents. Cleaning the driving systems sensors

Cleaning the windows and the wiper
blades
!
The windshield wipers must be in a
vertical position before folding them away
from the windshield. They could otherwise
damage the hood.
Never open
the hood when the wiper arms
are folded forward.
X Make sure the hood is fully closed.
X Switch on the ignition.
X Turn combination switch to wiper setting
° (Y page 280).
X With wiper arms in vertical position, switch
off the ignition. G
Warning!
For safety reasons, switch off wipers and
remove SmartKey from starter switch before
cleaning the windshield and/or the wiper
blades. Vehicles with KEYLESS-GO: Make
sure the vehicle’s on-board electronics have
status 0. Otherwise, the wiper motor could
suddenly turn on and cause injury.
! Do not pull on the wiper blade inserts.
They could tear.
X Fold the wiper arms forward until they snap
into place.
X Clean the windshield and the wiper blade
inserts with a clean cloth and mild
detergent solution.
X Use a soft, clean cloth and a mild window
cleaning solution on all outside and inside
glass surfaces.
An automotive glass cleaner is
recommended.
! Fold the

windshield wiper arms back onto
the windshield before turning the SmartKey
in the starter switch or pressing the
KEYLESS-GO start/stop button.
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 windshield.
! To clean the window interior, do not use
a dry

cloth, abrasives, solvents or cleaners
containing solvents. Do not touch the
inside of the windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.
Light alloy wheels If possible, clean wheels once a week.
X
Use Mercedes-Benz approved Wheel Care,
a soft bristle brush and a strong spray of
water for cleaning the light alloy wheels.
! Only use acid-free cleaning materials.
Acid may cause corrosion or damage the
clear coat.
! The vehicle should not be parked for an
extended period of time immediately after
it has

been cleaned. This applies especially
after the wheel rims have been cleaned
with wheel rim cleaner. Wheel rim cleaners
can lead to increased corrosion of the
brake disks and brake pads. Non-approved
wheel cleaners may also damage the wheel
paint if the vehicle is not driven after
cleaning.
Therefore, the vehicle’s brake system
should always be warmed-up before it is
parked after cleaning. Drive your vehicle for
several minutes to allow the brakes to dry.
When applying Mercedes-Benz approved
Tire Care and Mercedes-Benz approved
Wheel Care products, take care not to
spray them on the brake disks. 408
