Maintenance and care

R
solvents R
cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
! Do not park the vehicle for an extended
period straight after cleaning it, particularly
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 a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
Washing the vehicle and cleaning the
paintwork

carefully while paying attention to the traffic
conditions until full braking power is restored. ! Before driving into an automatic car wash,
make sure that it is suitable for the dimen-
sions of the vehicle. In particular, make
sure that: R
there is enough ground clearance
between the vehicle underbody and the
guide rails of the automatic car wash. R
the clearance width of the automatic car
wash is sufficient, particularly the width
of the guide rails. R
you enter the automatic car wash
straight and in the center of the guide
rails in order to avoid damaging the tires
or wheel rims.
Fold in the exterior mirrors before the vehi-
cle is washed. The exterior mirrors could
otherwise be damaged.
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations.
To prevent damage to the vehicle, deacti-
vate DISTRONIC PLUS and the HOLD func-
tion in the following or other similar situa-
tions: R
when towing the vehicle R
in the car wash
! Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
! Make sure that: R
the side windows and the sliding sunroof
are fully closed. R
the ventilation/heating is switched off
(the OFF button has been pressed). R
the windshield wiper switch is in position
0 .

wash from the very start.
If the vehicle is very dirty, pre-wash it before
cl e
aning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
shield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays. Observe the legal requirements in all coun-
tries concerned. X
Do not use hot water and do not wash the
