58 With the engine stopped, the parking brake acts
on the rear wheels via an electromechanical
system. When the engine is running, the park-
ing brake acts on the disk brakes of the front
and rear wheels via the brake hydraulics.
Setting manually
Pull button. The parking brake is set.
The indicator lamp in the instrument
panel lights up red. The parking brake is
set.
Indicator lamp on Canadian models.
The remote control does not have to be
inserted into the ignition lock for the parking
brake to be set.
While driving
If exceptional circumstances should make it
necessary to set the parking brake while the
vehicle is in motion, pull on the button longer.
The vehicle continues to brake forcefully for as
long as you pull on the button.
The indicator lamp in the instrument
panel lights up red, a chime sounds and
the brake lamps light up.
Indicator lamp on Canadian models.
As soon as you brake the vehicle almost to a
stop, i.e., down to a speed of approx. 2 mph/
3 km/h or below, the parking brake remains set.
Releasing manually
Press the button with the brake depressed.
The indicator lamp in the instrument
panel goes out.
Indicator lamp on Canadian models.
When leaving the vehicle, always take
along the remote control; this precaution
prevents children from releasing the parking
brake, for example.<
Automatic Hold
The concept
This function assists you as you drive by auto-
matically setting and releasing the parking
brake, e.g. when you are stopped at a traffic sig-
nal or in stop-and-go traffic.
When Automatic Hold is activated, the vehicle is
automatically held in place when standing.
When driving up inclines, the system prevents
your vehicle from rolling backward in an undes-
ired way.
After the engine is started, the system can be
activated and deactivated at any time the
driver's seat is occupied until the next time the
engine is switched off.

Activating
Press the button. The LED in the button lights
up and the indication AUTO H appears in the
instrument panel.
Automatic Hold is activated.
If the vehicle is being held by Automatic
Hold, the indicator light in the instru-
ment panel also lights up in green.

Deactivating
Press the button again, the LED in the button
and the indication AUTO H in the instrument
panel go out.
Automatic Hold is deactivated.
If the vehicle is being held by Automatic Hold,
then press on the brake pedal to deactivate it.
When the parking brake is set manually, refer to
page58, Automatic Hold is automatically deac-
tivated.
Driving
With Automatic Hold activated, the vehicle is
automatically prevented from rolling after it
comes to a stop.
The indicator lamp in the instrument
panel lights up in green.
Indicator lamp on Canadian models.
If the transmission is in a drive position, simply
press on the gas pedal to begin driving. The brake is automatically released and the indica-
tor lamp goes out.
Before driving into the car wash, deacti-
vate Automatic Hold; otherwise, the park-
ing brake will be automatically set after stop-
ping and the vehicle can no longer roll.<
Parking
If the vehicle is being held by Automatic Hold
and you switch off the motor, the parking brake
is automatically set.
The indicator lamp in the instrument
panel changes from green to red.
Indicator lamp on Canadian models.
The parking brake is not set if you have
already switched off the engine while the
vehicle is rolling to a stop.
Automatic Hold is deactivated.<
You can manually release the parking brake
even after switching off the motor as long as the
remote control remains in the ignition lock, refer
to page58. Use this function in car washes, for
example.
When leaving the vehicle, always take
along the remote control; this precaution
prevents children from releasing the parking
brake, for example.<
For your safety
Automatic Hold is automatically deactivated
when:
>the engine is switched off
>no one is detected in the driver's seat when
the engine is running
>the vehicle is braked to a stop during driv-
ing.
In the instrument panel, the indicator
lamp changes from green to red and
the indication AUTO H goes out.

The wiper operation is controlled automatically
as a function of the intensity of the rain. The rain
sensor is located on the windshield, directly in
front of the interior rearview mirror.
Rain sensor 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 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
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.
Washer fluid
Washer fluid antifreeze is flammable. For
this reason, keep it away from ignition
sources and store only in the closed original
container out of reach of children. Otherwise,
there is the danger of bodily injury. Always
observe the instructions for use provided on the
containers.<
Filler neck for washer fluid
Only add washer fluid with the engine
cooled down to exclude contact with hot
engine components. Otherwise there is a dan-
ger of fire and to personal safety if the fluid is
spilled.<
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.<

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 o r 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 panel.
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 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 to the resis-
tance point, the speed is increased 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 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.
