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.

Checking oil level
1.Park the vehicle on a level surface with
the engine at operating temperature
2.After approx. 5 minutes, pull the
dipstick 3 out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material3.Carefully push the dipstick all the way
into the guide tube and pull it out again
4.The oil should extend to between the
two marks on the dipstick.
The engine oil consumption is dependent
on driving style and driving conditions.
The oil quantity between the centers of the
two marks on the dipstick, refer to arrows,
is approx. 1.6 US quarts/1.5 liters. Do not
fill beyond the upper mark on the dipstick.
Excess oil can damage the engine.
