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 to which you
may be accustomed, 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 page73 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 the vehicle is equipped with a Professional
navigation system, the system adapts the
acceleration and deceleration behavior of the
vehicle to the road on which you are currently
driving.
To ensure that the system has the latest
information on the course of the road, use
the most recent version of the navigation
data.<
If the vehicle position is unknown, e. g. if you
have left the region covered by the map, the
navigation system ceases to influence vehicle
behavior.
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 con-
gestion. Do not use the system in city driving; in
complex driving situations; heavy traffic such as
during rush hour; on curvy, winding roads, slip-
pery roads or roads with sharp curves such as
highway off-ramps; during inclement weather
such as snow, strong rain or fog; or when enter-
ing 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

the system is interrupted and the distance indi-
cator goes out until the pedal is fully released.
As soon as you fully release the accelerator, the
system will again control your cruising speed
and distance setting. While driving with the sys-
tem activated, resting your foot on the acceler-
ator pedal will cause the system not to brake
even if necessary. Be certain that floor mats or
other objects on the vehicle floor do not inter-
fere with movement of the accelerator pedal.<
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, e. g.
when you reduce your desired speed sharply. It
uses only a portion of braking system capacity
and does not utilize the full capacity of the vehi-
cle braking system. Therefore, the system can-
not decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approaching a toll booth or when
a much slower vehicle cuts in front of you at
close range.<
