Activating rain sensor
Press the button, arrow3. The LED in the but-
ton lights up.
Adjusting rain sensor sensitivity level
Turn the knurled wheel5.
Deactivating rain sensor
Press the button again, arrow3. The LED goes
out.
Deactivate the rain sensor when passing
through an automatic car wash. Failure to
do so could result in damage caused by undes-
ired wiper activation.<
Cleaning windshield and headlamps
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
When the vehicle lighting system is switched
on, the headlamps are also cleaned at regular
and appropriate intervals.
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do so, your vision could be
obscured. To avoid freezing, use a washer fluid
antifreeze, refer to Washer fluid. Do not use
washers when the washer fluid reservoir is
empty, as this will damage the washer pump.<
Windshield washer nozzles
Both windshield washer nozzles are automati-
cally heated with the engine running or the igni-
tion switched on.
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks and
open flames, and store it in tightly closed con-
tainers well out of the reach of children. Always
follow the instructions for use provided on the
containers.<
Washer fluid reservoir
Capacity approx. 5.3 US quarts/5 liters.
Fill with water and – if required – with a washer
antifreeze, according to manufacturer's recom-
mendations.
In order to maintain the mixture ratio, mix
the washer fluid before filling.<
Cruise control
The concept
Cruise control is available for use at speeds of
approx. 20 mph/30 km/h and higher. The vehi-
cle stores and maintains the speed that you set
using the lever mounted on the steering col-
umn.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads , in heavy traffic or in poor roa d co nditions
such as snow, rain, ice, and loose road surface.
Otherwise, you could lose control of the vehicle
and cause an accident.<
