lowers section of switch.
Adjusting active backrest width*
First set a comfortable backrest width, see
above. Based on the backrest width set, the lat-
eral support is automatically adapted to the cur-
rent driving situation.
The adaptation of the backrest width and the
speed of the adjustment vary depending on the
program. You can select from among three pro-
grams from comfort to sport.

are being worn at all of the occupied seats. Air-
bags complement the safety belt as an addi-
tional safety device, but they do not represent a
substitute.
Fastening
Make sure you hear the latch plate engage in
the belt buckle.

tion.
Active seat ventilation*
The appearance and arrangement of the but-
tons may vary depending on the equipment.
1Active seat ventilation
2Active seat ventilation with seat heatingPress the respective button once per ventila-
tion level. The ventilation level appears on the
Control Display. The maximum level is supplied
when three LEDs are lit.
The air quantity is reduced and if need be, the
ventilation is switched off in order to reduce the
load on the battery. The LEDs remain lit.
To switch off: press button longer.
The highest level is used for rapid cooling,
e.g. when the vehicle has become heated
up. After a short time, the system is automati-
cally switched down one level in order to pre-
vent excessive cooling.<
Active seat*
The seat cushion is actively varied by alter-
nately raising and lowering the right and left half
of the seat cushion. This reduces muscular ten-
sion and fatigue to help prevent lower back
pain.
Press the button to switch on; the LED lights
up.
The action of the system is reduced and if need
be, switched off in order to reduce the load on
the battery. The LED remains lit.

Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
firmly. In doing so, continuously press the but-
ton of the handbrake lever. Otherwise, too firm
an application of the handbrake can lock up the
rear wheels and cause the rear of the car to
swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<
Manual transmission
While shifting in the 5th/6th gear lane,
press the gearshift lever toward the right,
otherwise accidental shifting into the 3rd or 4th
gear could result in engine damage.<

Do not use the washing mechanisms 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.<

In addition to holding a steady cruising speed, if
you encounter slower vehicles ahead, active
cruise control will, within limits, adjust your
vehicle's speed automatically so that you can
flow with the traffic without having to make con-
stant adjustments. If, for example, while cruis-
ing at the selected speed, you begin to
approach a slower vehicle ahead of you in the
same lane, the system will reduce your vehicle's
speed to the same as that of the vehicle ahead
to maintain your selected distance setting. You
can vary the following distance, which will vary
with speed. Based on your selected distance
setting, the system automatically decreases the
throttle setting and lightly applies the brakes if
necessary. In addition, if the vehicle ahead of
you slows to a complete stop, the system can
follow this action within the given scope and
can also accelerate from a complete stop if the
vehicle ahead of you drives off again shortly
thereafter. During braking, your vehicle brake
lamps will automatically illuminate to alert a fol-
lowing driver to take action. In addition, it may
be necessary for your vehicle to downshift the
automatic transmission to maintain the dis-
tance setting selected. As soon as the road in
front of you has no moving vehicles, the system
will accelerate to your desired speed. This set
speed is also maintained on downhill grades,
however the vehicle speed can drop below the
set speed when driving uphill if the engine out-
put is not sufficient.
Active cruise control cannot detect stop
signs, red lights, or any object that is
stopped or is blocking the road.
Active cruise control is not and must not be
used as a collision avoidance/warning system.
Since this active cruise control system is a new
technology and operates differently from con-
ventional cruise control systems which you may
be accustomed to, it is necessary that you read
all of the pages relating to this system before
use. Carefully read and observe the information
on the system limitations beginning on page75
to obtain a good command of the system and its
range of applications. When the system brakes and you also depress
the brake pedal, a somewhat different braking
feel results.
Professional* navigation system
If a navigation DVD is in the drive, refer to
page142, within limits the system adjusts the
accelerating and braking behavior of the vehicle
to the road you are driving on.
To ensure that the system is informed of
the current course of the road, always use
the latest navigation DVD if possible.<
When the vehicle position is unknown, e. g.
when you leave the map area, this influence of
the navigation system is not available.
Applications
Please try the system first during sparse traffic
and clear road conditions so that you can get
used to the system. After you have experience
and understand the system, only then use it
during normal traffic.
As with conventional cruise control systems,
active cruise control in no way reduces or sub-
stitutes for the driver's own personal experi-
ence, responsibility, alertness and awareness in
adjusting speed, braking or otherwise control-
ling the vehicle. The driver should decide when
to use the system on the basis of road, traffic,
visibility, and weather conditions. Active cruise
control is intended for use on highway-type
roadways where traffic is moving relatively
smoothly as well as in slow-moving traffic. Do
not use the system in city driving; in complex
driving situations; heavy traffic such as during
rush hour; on curvy, winding roads, slippery
roads or roads with sharp curves such as high-
way off-ramps; during inclement weather such
as snow, strong rain or fog; or when entering
interchanges, service/parking areas or toll
booths. It is also important to regulate your
vehicle's speed and distance setting within
applicable legal limits. Always be ready to take
action or apply the brakes if necessary, espe-
cially when the system is actively following a
vehicle in front of you. Otherwise, driving condi-

The system indicates that you
must brake and/or maneuver the
vehicle yourself. The system can-

However, this display cannot relieve the driver
of the responsibility for adjusting the desired
speed and driving style to the traffic conditions.
Radar sensors

*
Heavy rain and also dirt, snow or ice can limit
the detection of vehicles ahead. If needed,
clean the radar sensor under the front bumper
as well as the bumper area covering the short
range sensors. When doing so, be particularly
careful in removing layers of snow and ice.
Do not apply adhesive labels etc. in the area of
the short-range sensors.
If the sensor is not aligned properly, e. g. due to
damage, the active cruise control cannot be
activated.
