Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers when
the windscreen is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windscreen can scratch the
glass if wiping takes place when the wind-
screen is dry.
If it is necessary to switch on the windscreen wipers in dry weather conditions, always
operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may be
due to wax or other residue. Clean the wind-
screen with washer fluid after an automatic
car wash. !
Intermittent wiping with rain sensor: due to
optical influences and the windscreen becom-
ing dirty in dry weather conditions, the wind-
screen wipers may be activated inadvertently. This could damage the windscreen wiper
blades or scratch the windscreen.
For this reason, you should always switch off
the windscreen wipers in dry weather. 1

is lowered. This can cause you or others to
become trapped between the vehicle body
and tyres, or underneath the vehicle. This
poses a risk of injury.
Make sure that no-one is in the immediate
vicinity of the wheel arch or underneath the
vehicle when disconnecting the trailer cable.
! Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun

50 mA.
To ensure reliable indication of the failure, each LED chain in the trailer lighting must be guaran-
teed a minimum current of 50 mA. Trailer with 7-pin connector
