Switching on wipers
Pull the lever upward, arrow1.
The lever automatically returns to its initial posi-
tion when released.
Normal wiper speed
Press once.
The system reverts to operation in the intermit-
tent mode when the vehicle is stationary.
Fast wiper speed
Press twice or press beyond the resistance
point.
The system reverts to normal speed when the
vehicle is stationary.
Rain sensor*
The wiper operation is controlled automatically
as a function of the rain intensity. The rain sen-
sor is located on the windshield, directly in front
of the interior rearview mirror.
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*
Pull the lever, arrow4.
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
When the vehicle lighting is switched on, the
headlamps are simultaneously washed at
appropriate intervals.

64 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
washing mechanisms when the washer fluid
reservoir is empty, otherwise you 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.
Rear window wiper
1Intermittent mode. When reverse gear is
engaged, continuous operation is switched

2Cleaning the rear window
Do not use washing mechanisms when
the washer fluid reservoir is empty, other-
wise you will damage the washer pump.<
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
All washer nozzles are supplied from one reser-
voir.
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.<
Capacity
approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
The cruise control with a braking function is
available for use at speeds of approx. 20 mph/
30 km/h and higher. The vehicle stores and
maintains the speed that you set using the lever
mounted on the steering column. To keep the
specified speed constant, the system brakes if
the engine braking effect is not sufficient on a
downhill grade.
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.<

Maintaining current speed
Briefly press, arrow1, or briefly pull, arrow2
lever.
The speed currently being driven is stored and
maintained. It is indicated on the speedometer
and briefly in the instrument cluster.
The controlled speed can drop on uphill grades
if the engine output is insufficient. If the engine
braking effect is not sufficient on a downhill
grade, the system lightly brakes the vehicle.
Increasing desired speed
Repeatedly press the lever up to or beyond the
resistance point, arrow1, until the desired
speed is set.
>Each time the lever is pressed up to the
resistance point, the desired speed
increases by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed
increases by a maximum of 5 mph or
10 km/h.
The system stores the setting and maintains
the set speed.
Accelerating with lever
Accelerate slightly:
Press the lever up to the resistance point,
arrow1, until the desired speed is reached.
Accelerate more rapidly:
Press the lever beyond the resistance point,
arrow1, until the desired speed is reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores the
setting and maintains the set speed.
Reducing desired speed
Repeatedly pull the lever up to the resistance
point or beyond, arrow2, until the desired
speed is displayed.
>Each time the lever is pulled up to the resis-
tance point, the desired speed decreases
by approx. 1 mph or 1 km/h.
>Each time the lever is pulled beyond the
resistance point, the desired speed is
decreased by a maximum of 5 mph or
10 km/h until the minimum speed of
20 mph or 30 km/h is reached.
The system stores the setting and maintains
the set speed.
If the speed is to be considerably
reduced, depress the brake, as otherwise
a dangerous situation could result due to insuf-
ficient deceleration.<
Deactivating cruise control
Briefly press the lever up or down, arrow3.
The displays in the speedometer go out.
In addition, the system is automatically deacti-
vated:
>when braking
>when transmission position N is engaged
>when DTC is activated or DSC is deacti-
vated
>when HDC is activated
>when DSC or ABS is active
Accelerating does not deactivate the cruise
control. After releasing the accelerator pedal,

again.
Warning lamp
The warning lamp lights up when the
cruise control has automatically been
deactivated by braking with the park-
ing brake or by a control intervention by DSC.
A message appears on the Control Display.
Resuming stored speed
Briefly press the button, arrow4. The stored
speed is resumed and maintained.
In the following cases the stored speed value is
deleted and can no longer be resumed:
>in case of an intervention of the driving sta-
bility control systems
>when transmission position N is engaged
>when the ignition is switched off
