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.
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.
Plastic and rubber parts
XUse a gentle dishwashing detergent or mild
detergent for delicate fabrics as a washing
solution.XWipe with a cloth moistened in a lukewarm
solution.
The surface may temporarily change color.
If this is the case, wait for it to dry.GWarning!
Do not use cleaners or cockpit care sprays
containing solvents to clean the cockpit or the
steering wheel. Cleaners containing solvents
will make the surface porous and vehicle
occupants could suffer serious injuries from
plastic parts coming loose in the event of air
bag deployment.
! Do not use oil, wax or scouring agents.
Otherwise you may scratch or damage the
surface.
Hard plastic trim items XUse Mercedes-Benz approved Interior Care
on a soft, lint-free cloth and apply with light
pressure.
COMAND display
! You must switch off the COMAND display
and allow it to cool prior to cleaning.
! Do not use any liquids or cleaning agents.
These can damage or even destroy the
COMAND display screen.
XUse a standard microfiber cloth and apply
with light pressure.
Steering wheel and gear selector lever
XWipe with a damp cloth and dry thoroughly
or clean with Mercedes-Benz approved
Leather Care.
Carpets
XUse Mercedes-Benz approved Carpet and
Fabric Care for cleaning the carpets.
Headliner
XUse a soft bristle brush or a dry-shampoo
cleaner in case of excessive dirt.
Seat belts
XOnly use clear, lukewarm water and soap.
! The seat belts must not be treated with
chemical cleaning agents. Do not dry the
seat belts at temperatures above 176‡
(80†) or in direct sunlight.

If necessary, apply full pressure to the brake

messages appear in the multifunction display
while driving. To brake, the driver must then
apply significantly greater brake pedal
pressure and depress the pedal much further
to obtain the expected braking effect. If
necessary, apply full pressure to the brake
pedal. Brakes are only applied to the front
wheels. Stopping distance is increased! For
more information, see “Electro-hydraulic
brake system” in this in this Operator’s
Manual.
If there is a malfunction in the electro-
hydraulic brake system, we recommend that
the vehicle be transported with all wheels off
the ground using flatbed or appropriate wheel
lift/dolly equipment.
If circumstances do not permit the
recommended towing methods, the vehicle
may be towed with all wheels on the ground
or one axle raised only so far as necessary to
have the vehicle moved to a safe location
where the recommended towing methods
can be employed.XSwitch off the tow-away alarm before
towing the vehicle with all wheels on the
ground or one axle raised ( Y page 64).
!
Before towing the vehicle observe the
following instructions:
R Do not tow-start the vehicle. You could
otherwise seriously damage the
automatic transmission which is not
covered by the Mercedes-Benz Limited
Warranty.
R Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
R Towing of the vehicle should only be
done using the properly installed towing
eye bolt. Never attach a tow cable, tow
rope or tow rod to the vehicle chassis,
frame or suspension parts.
GWarning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
! Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
! Do not use the towing eye bolt for
recovery, as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
i If the battery is disconnected or
discharged
R the SmartKey will not turn in the starter
switch
R the automatic transmission will remain in
park position P
For more information see “Battery”
( Y page 283) or “Jump starting”
( Y page 285).
Installing towing eye bolt
Depending on whether you are towing a
vehicle or you are being towed, the towing eye
bolt can be screwed into threaded holes
which are located behind covers on each
bumper.
The towing eye bolt is supplied with the
vehicle tool kit, located in the compartment
underneath the trunk floor ( Y page 224).
XTake the vehicle tool kit out of the trunk.
Removing cover in front bumper
XPress mark on cover : as indicated by the
arrow.XLift cover : off to reveal the threaded hole
for the towing eye bolt.288Towing the vehiclePractical hints
