3Activating/deactivating rain sensor 
4Cleaning windshield and headlamps 
5Adjusting rain sensor sensitivity level 
The lever automatically returns to its initial 
position when released. 
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 inter-
vals. 
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. 
Avoid activating the washer when the res-
ervoir is empty, as damage to the pump 
could result.<
Windshield washer nozzles 
The windshield washer nozzles are auto-
matically heated in ignition key position 2. 
Rain sensor 
The rain sensor controls windshield wipe 
operation depending on the amount of rain. 
The rain sensor is located on the wind-
shield, directly in front of the interior rear-
view mirror. 
Activating rain sensor 
As of ignition key position 1, briefly press 
the button. The indicator lamp in the button 
lights up. The wipers will always respond 
by completing at least one sweep of the 
windshield. 
Adjusting rain sensor sensitivity level 
Turn the serrated dial 5. 
Deactivating rain sensor 
Press the button again. The indicator lamp 
goes out. 
The rain sensor is automatically deacti-
vated when you switch off the ignition.

Driving
62 Deactivate the rain sensor when 
passing through an automatic car 
wash. Failure to do so could result in dam-
age caused by undesired wiper activa-
tion.<
Washer fluid 
Washer fluid antifreeze is flammable. 
Always keep it well away from sparks 
and open flames, and store it in tightly 
closed containers 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 manufac-
turer's recommendations.
In order to keep to 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 column.
Do not use the cruise control when 
driving on winding roads, in heavy 
traffic or in poor road conditions – e.g. 
snow, rain, ice, loose road surface – that do 
not permit a constant speed.<
One lever for all functions 
1Maintaining and storing speed, 
accelerating 
Press the lever up to the resistance point:
The system maintains and stores the cur-
rent vehicle speed. The display 1 in the 
speedometer indicates this regulated 
speed, refer to page 63. Every time you 
briefly press the lever, the vehicle's speed 
increases by roughly 1 mph/1 km/h.
Press the lever up to the resistance point 
and hold it: 
The vehicle accelerates without pressure 
on the accelerator pedal. The system main-
tains and stores your current speed as 
soon as you release the lever.
Press the lever beyond the resistance 
point:
Increases the speed by 5 mph/10 km/h.
The vehicle may accelerate beyond the 
regulated speed on steep downhill 
stretches where the engine's braking effect 
alone may not be sufficient to slow the 
vehicle. Speed can drop on uphill grades if 
the engine output is insufficient.
2 Maintaining and storing speed, 
decelerating 
Pull the lever:
Functions are the same as 1, only the vehi-
cle speed is reduced.
3Interrupting cruise control 
With the cruise control active, briefly press 
the lever up or down.
