Cleaning the windows and the wiper
blades

are folded forward.
G
Warning!
For safety reasons, switch off wipers and
remove SmartKey from starter switch
(vehicles with KEYLESS-GO: Make sure the
vehicle’s on-board electronics have status
0) 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.
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 (vehicles
with KEYLESS-GO).
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 front, rear or side windows
with hard objects such as an ice scraper or
ring. Doing so may damage the windows.
Cleaning the panorama roof with power
tilt/sliding panel
The rear part of the tilt/sliding panel has a
protective layer on the inside.
X
Use a soft, clean cloth and a mild window
cleaning solution.
An automotive glass cleaner is
recommended.
! Do not use a dry cloth, abrasives, solvents
or cleaners containing solvents. Do not
touch the protective layer with hard objects
such as an ice scraper or ring. Never apply
strong force and only use a soft, non-
scratching cloth when cleaning the rear
part of the tilt/sliding panel.
Otherwise you may scratch or damage the
protective layer.
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, especially not 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.
