cleaning solution on all outside and
inside glass surfaces.
An automotive glass cleaner is recom-
mended.Light alloy wheels
If possible, clean wheels once a week.
Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light al-
loy wheels.!Do not pull on the wiper blade inserts. They
could tear.
!Fold the windshield wiper arms back onto
the windshield before turning the SmartKey in
the starter switch.
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 con-
taining 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.
Warning!G
Do not clean the rear window with the hard-
top in a position other than the fully raised
and closed position. Otherwise, the hardtop
may move unexpectedly which may result in
personal injury to you or others.!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 corro-
sion of the brake discs and brake pads.
Non-approved wheel cleaners may also damage
the wheel paint if the car is not driven after
cleaning. Therefore, the vehicle’s brake system
should always be warmed-up before it is parked
after cleaning. To do so, please 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 discs.
406 Practical hints
Replacing wiper blades
Placing wiper arms in vertical position
1Wiper arms
Turn the SmartKey in the starter switch
to position1 (
page 37).
Turn combination switch to wiper
settingII (
page 56).
With wiper arms 1 in vertical position,
turn the SmartKey in the starter switch
to position0.
Remover the SmartKey from the starter
switch.
Warning!G
For safety reasons, switch off wipers and
remove the SmartKey from the starter
switch before replacing a wiper blade.
Otherwise, the motor could suddenly turn
on and cause injury.
Warning!G
Wiper blades are components that are
subject to wear and tear. Replace 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 a 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.
For your convenience, we recommend that you
have this work carried out by an authorized
Mercedes-Benz Center.
