Especially on longer trips and in traffic conges-
tion, the system can reduce fatigue and tension,
while increasing your enjoyment of driving.
Please use it safely and responsibly.
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 page71
to obtain a good command of the system and its
range of applications.<
Brake pedal feel
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
page132, 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

While stopped
Before leaving the vehicle with the engine
running, engage position P of the auto-
matic transmission and apply the handbrake.
Otherwise the vehicle can roll.<
If a detected vehicle in front of you brakes to a
complete stop and your vehicle has also been
braked to a complete stop by the system:
>If the vehicle in front of you drives off while
the marking1 for the desired speed in the
speedometer is green, your vehicle will
accelerate without you having to do any-
thing.
>If the vehicle in front of you drives off while
the marking1 is orange, you briefly depress
the accelerator pedal or press button4.
Rolling bars in the distance indicator3
mean that the vehicle in front of you has
driven off.
If you are stopped behind a vehicle with the
brake pedal depressed and the system is inter-
rupted or deactivated:
1.Press button4 to activate a stored desired
speed or select a desired speed with the
lever, arrow1 or arrow2.
2.Release the brake pedal.
3.If the vehicle in front of you drives off, briefly
depress the accelerator pedal or press
button4.

The system indicates that you
must brake and/or maneuver the
vehicle yourself. The system can-
not automatically restore the distance to the

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

Radar sensors
1Long-range sensor
2Location of the short-range sensors behind
the bumperHeavy 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.
System limitations
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling 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 free-
way-type roadways where traffic is moving rel-
atively smoothly. Do not use this system in city
driving; in complex driving situations; on curvy,
winding roads, slippery roads or roads with
sharp curves such as highway 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 nec-
essary, especially when the system is actively
following a vehicle in front of you.
tions. For example, the system may not detect
vehicles driving ahead if they suddenly brake
heavily in stop-and-go traffic during accelera-
tion. The system will not apply the brakes or
slow your vehicle when a very slow-moving
vehicle, stopped vehicle or stationary object is
in the lane ahead of you, for example when
approaching a traffic light or parked vehicle or
when a vehicle is stalled in your lane. Also, the
system does not react to oncoming traffic,
pedestrians or other types of potential traffic
such as a rider on a horseback. It is also possible
that the system may not detect smaller moving
objects such as motorcycles or bicycles. Be
especially alert when encountering any of these
situations as the system will neither automati-
cally brake, nor provide a warning to you. Also,
be aware that every decrease in the distance
setting allows your vehicle to come closer to a
vehicle in front of you and requires a heightened
amount of alertness.<

function in the monitored systems. A Check
Control message of this kind includes indicator
or warning lamps in the instrument cluster, pos-
sibly an acoustic signal, and text messages at
the bottom of the Control Display.
Indicator and warning lamps
The indicator and warning lamps can light up in
different combinations and colors. This symbol means that a Check Control
message has been generated. The symbol
remains visible even if the Check Control mes-
sage has been hidden after a short time. The
combinations of warning lamps and text mes-
sages are stored and can be viewed later, also
refer to page80.
