advisable to brake the vehicle with
considerable force prior to parking. The heat
generated serves to dry the brakes.
Salt-covered roadsGWarning!
A layer of salt on the brake discs and the brake
linings may cause a delay in the braking
effect, resulting in a significantly increased
braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully when you are
driving on salt-covered roads, so that any
layer of salt that may have built up on the
brake discs and the brake linings is
removed without putting other road users
at risk
R maintain a greater distance to the vehicle
ahead and drive with particular care
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake disc
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.
GWarning!
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.
!  Because the ESC operates automatically,
the engine and ignition must be shut off
(KEYLESS-GO start/stop button in position
0  or  1, or SmartKey in starter switch
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 the rear 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.
GWarning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Refer to the description of the Brake Assist
System (BAS) ( Y page 62).
High-performance brake system and
ceramic brake system    
GWarning!
New vehicle brake pads and disks, and
replacement brake pads and disks may take
several hundred miles of driving until they
provide optimum braking efficiency. Until that
time, you may need to use increased brake
pedal pressure while braking. Please be aware
of this and adjust your driving and braking
accordingly during this break-in period.

XOnly use clean water and a soft, non-
scratching cloth to clean rear view camera
lens  0046.
Be careful not to apply wax to rear view
camera lens  0046 when waxing the vehicle. If
necessary, remove the wax using the
Mercedes-Benz approved Car Shampoo with
plenty of water.
!  Do not clean the camera and the area
around the camera
R with a high-pressure cleaner
R with a dry cloth and strong pressure
R with aggressive cleaning agents
You could otherwise damage the camera.
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.
XMake sure the hood is fully closed.XSwitch on the ignition.XTurn combination switch to wiper setting
00B6  (Y  page 253).XWith wiper arms in vertical position, switch
off the ignition.GWarning!
For safety reasons, switch off wipers and
remove SmartKey from starter switch before
cleaning the windshield and/or the wiper
blades. 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.
XFold the wiper arms forward until they snap
into place.XClean the windshield and the wiper blade
inserts with a clean cloth and mild
detergent solution.XUse 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 pressing the
KEYLESS-GO start/stop button or 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
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.
XUse 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.

Towing with rear axle raised
!  The vehicle may be towed only for
distances up to 30 miles (50 km) and at a
speed not to exceed 30 mph (50 km/h).
When towing the vehicle with the rear axle
raised, the wheels on the ground have to
move freely. Therefore follow the respective
steps below, after the rear axle being raised:
XSwitch on the hazard warning flasher
( Y  page 252).XMake sure the transmission remains in
neutral position  N. Observe instructions,
see “Shifting into neutral position  N”
( Y  page 263).! 
Because the ESC operates automatically,
the engine and ignition must be shut off
(KEYLESS-GO start/stop button in position
0  or  1, or SmartKey in starter switch
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 the rear 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.
!  Keep in mind that it is important for the
SmartKey to be left in starter switch with
the ignition switched off. As soon as the
SmartKey is removed from the starter
switch the transmission will shift to park
position  P.
Towing with all wheels on the ground
GWarning!
When there is a malfunction in the brake
system, the vehicle must be towed using a tow
bar.
Before towing make sure the steering wheel
is unlocked and can be moved.
The vehicle must not be towed when the
power supply or the vehicle’s electrical
system are malfunctioning.
GWarning!
While the vehicle is being towed,
R the engine may turn off
R the electrical system may fail
R the battery voltage may drop too far.
All or any of this will block the rear axle.
This could cause an accident and injure you
and/or others.
!  You must not use the KEYLESS-GO start/
stop button when towing the vehicle. Use
the SmartKey instead.
