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 res-
ervoir is empty, as otherwise the washer pump
will be damaged.
<
Windshield washer nozzles
The windshield washer nozzles are automati-
cally heated in ignition key position 2.
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
observe 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 maintain the mixture ratio, mix
the washer fluid before filling.

Cruise control
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle maintains and stores 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 road conditions such
as snow, rain, ice, and loose road surface.
