after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for afew minutes after cleaning.
Brakin gheats the brake discs and the brake

Washing the vehicle and cleaning the
paintwork
Automatic car wash
GWARNING
Brakin gefficiencyisr educed after washing
the vehicle. There is arisk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
!If DISTRONIC PLUS or the HOLD function is
activated, the vehicle brakes automatically in
certain situations.
To prevent damage to the vehicle, deactivate DISTRONIC PLUS and the HOLD function in
the following or other similar situations:
Rwhen towing the vehicle
Rin the car wash
!It is preferable to use car washes with
adjustable high-pressure pre-cleaningt hat
corresponds to the specification for the Cab-
riolet program. In car washes that use high
water pressures, there is arisk that asmall
amount of water may leak into the vehicle.
!Designo retractable hardtop: make sure
that the vehicle is not subsequently treated
with hot wax.
!Lock the car if you wash it in an automatic
car wash. Otherwise, the vehicle might be
damaged.
!Never clean your vehicle in aTouchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
If you have your vehicle cleaned in ahigh-
pressure automatic car wash, small amounts
of water may enter the vehicle.
!Make sure that the automatic transmission
is in position Nwhen washing your vehicle in
at ow-through car wash. The vehicle could be

Maintenance and care

!Make sure that:
Rthe side windows and the roof are com-
pletely closed
Rthe climate control blower is switched off
Rthe windshieldwiper switch is at position 0
The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off wax
from the windshielda nd the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield.
Washing by hand
In some countries, washing by hand is only
allowed at speciallye quipped washing bays.

blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nentsd amagedint his way may fail unexpect-
edly.T here is arisk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis componentsr eplaced imme-
diately.

!Do not use high-pressure cleaners if the
tank recess is open while you clean it. This
can cause damage to the seals or other com-
ponents.
Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic plates or similari tems
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by

HEnvironmental note
Hav ethe used tire sealant bottle dispose dof
professionally, e.g .ataqualified specialist
workshop.
If tire pressure of 200 kPa (2.0 ba r/29 psi )has
beena chieved after amaximu mperiod of ten
minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of the
faulty tire.
XStow the tire sealant bottle and the tire infla-
tion compressor.
XPull away immediately.
XStop after driving for approximately ten
minutes and check the tire pressure with the
tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for ashort period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
iIn cases such as the one mentioned above,
contact an authorized Mercedes-Benz Cen-
ter. Or call 1-800-FOR-MERCedes( in the
USA) or 1-800-387-0100 (i nCanada).
XCorrect the tire pressure if it is stil latleast
