Automatic car wash G
Risk of accident
Braking efficiency is reduced after washing
the vehicle. This could cause an accident.
After the vehicle has bee nwashed, brake
firmly while paying attention to the traffic con-
ditions. This will warm up the brake discs,
thereby drying them mor equickly. Afte rwash-
ing the vehicle, drive particularly carefully
until the brakes are dry and braking power has
been fully restored.
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.
! When washing your vehicle in a tow-
through car wash, use the key instead of
the Start/Stop button.
Start the engine .Move the transmission
selector lever to N. Switch the engine off
again and make sure that you then leave
the key in position 2.You may otherwise
damage the vehicle, the transmission or
the car wash.
Check the transmission position in the
instrument cluster.
! Before switching off the engine, shift the
transmission to N. If you open the driver's
or front-passenger door, the transmission
remains in this position for up to 30
minutes if the key is in the ignition, even if
the engine is switched off. If you do not shift
the transmission to Nbeforehand, it shifts
automatically to parking position Pand
locks the wheels if the driver's or front-
passenger door is opened and the engine
is switched off. This may damage the vehi-
cle, the transmission or the car wash. !
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 centre of the guide
rails in order to avoid damaging the tyres
or wheel rims.
Fold in the exterior mirrors before the vehi-
cle is washed. The exterior mirrors could
otherwise be damaged.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is fully turned off and that the wind-
screen wiper switch is set to 0.Otherwise,
the rain/light senso rmay be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
! In portal car washes, the windscree nwip-
ers may be moved up the windscreen by the
cleaning brushes when the ignition is
switched off.
Set the Start/Stop button to key position
2 to reset the windscreen wipers to their
original position.
! Vehicles with a mat tfinish*:
Do not use wash programs with a hot wax
treatment under any circumstances.
After using an automatic car wash, wipe off
wax and drying agents fro mthe windscreen
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windscreen. Care
