Brake service !
The brake fluid level in the reservoir may
be too
low if the red brake warning lamp in
the instrument cluster comes on while the
engine is running and an acoustic warning
sounds. Observe additional messages in
the multifunction display that may appear.
Brake pad wear or a leak in the system may
be the reason for low brake fluid in the
reservoir.
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Only install brake pads and use brake fluid
recommended by Mercedes-Benz. G
Warning!
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can
be degraded to an extent that safe
braking is substantially impaired. This could
result in an accident.
! Vehicles with 4MATIC:
Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz Center. You could
otherwise seriously damage the brake
system or the transfer case which is not covered by the Mercedes-Benz Limited
Warranty.
! Vehicles with 4MATIC:
Because the ESC operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position 0 or
1 or KEYLESS-GO start/stop button in
position 0
or 1
) when the electronic parking
brake is being tested on a brake test
dynamometer.
Active braking action through the ESC may
otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
! Vehicles without 4MATIC:
Because the ESC operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position 0 or
1 or KEYLESS-GO start/stop button in
position 0 or 1) when the electronic parking
brake is being tested on a brake test
dynamometer or when the vehicle is being
towed with one axle raised.
Active braking action through the ESC may
otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
If your brake system is only subjected to
moderate loads, you should occasionally test
the effectiveness of the brakes by applying
above-normal braking pressure at higher
speeds. This will also enhance the grip of the
brake pads. G
Warning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.

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
