° Continuous wiping, slow
¯ Continuous wiping, fast
To switch on: switch the ignition on.
#
Turn the wiper switch to the desired position
#
depending on the intensity of the rain.
Vehicles with rain and light sensor: if the Ä
or Å setting is used, an appropriate wipe fre‐
quency will be set according to rainfall. In the
Å position, the rain and light sensor is more
sensitive than in the Ä position, causing the
windscreen wipers to wipe more frequently. If the
rain and light sensor fails, the wiper will automati‐
cally switch to the wiping interval corresponding
to the position of the switch.
Using the windscreen washer system
Combination switch (example)
Single wipe: press the î button briefly.
#
To wipe the windscreen using washer
#
fluid: press and hold the î button.
Vehicles with the headlamp cleaning system:
once the ignition has been switched on, if the
windscreen is washed with washer fluid for the
first time with the dipped-beam headlamps
switched on, the headlamps will also be cleaned.
If you wash the windscreen with washer fluid ten
times with the dipped-beam headlamps switched
on, the headlamps will also be cleaned once.
Switching the windscreen heater on/off
The windscreen heater is operational when the
engine is running and will deactivate automati‐
cally after approximately 15 minutes.
To switch on/off: press è button under
#
the
Climate control
menu in the multimedia
system.
When the indicator lamp on the è button
lights up, the windscreen heater is switched
on.
Notes on winter use
Headlamps
If the plastic covers on the headlamps ice up in
winter, do not use an ice scraper to remove the
layer of ice. If you do, you could scratch the plas‐
tic covers. Use only de-icer spray that is suitable
for plastic surfaces.
Windscreen washer system
At temperatures of approximately 5°C to -5°C
accompanied by snowfall, direct the air to the
windscreen using the z or ¯ air-distribu‐
tion control (
page 110). You can also switch
/
on the windscreen heater. With these settings,
the wiper blades on the windscreen will be
heated. You can thereby prevent smearing or the
snow freezing on the wiper blade.
Power supply
Using the battery disconnect switch
& WARNING Risk of an accident by press‐
ing the battery disconnect switch while
the vehicle is in motion
If the power supply is interrupted with the
battery disconnect switch, the engine is
switched off automatically. Safety-relevant
functions may therefore be restricted or
unavailable, e.g. power steering, lighting sys‐
tem and ABS. The compressed-air supply sys‐
tem fails.
You will then need to apply significantly more
force when steering. The wheels may lock
during braking. Also, the spring-loaded park‐
ing brake can activate if there is a loss of
compressed air and the vehicle may then
brake uncontrollably. You could lose control
of the vehicle.
Only press the battery disconnect
#
switch when the vehicle is stationary
and the parking brake is applied.
