Always remember that the range and
ability of the system does have phys-
ical limitations. It will not apply the brakes
or decelerate your vehicle when there is a
slow-moving vehicle, stopped vehicle or
stationary object ahead of you, as for
example, at a traffic light or a parked vehi-
cle. Also, the system does not react to
oncoming traffic, pedestrians or other type
of potential traffic such as a rider on horse-
back. It is also possible that the system
may not detect smaller moving objects
such as motorcycles or bicycles. Be espe-
cially alert when encountering any of these
situations as the system will neither auto-
matically 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 alert-
ness.<
If while your vehicle is actively following a
vehicle in front of you and the vehicle
ahead speeds up or the lane ahead
becomes clear, then your vehicle will
accelerate to the speed you have selected.
Be aware that changing to a clear, unob-
structed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system
when you pull into an exit lane for a
highway off-ramp.<
Also, vehicles traveling in a staggered man-
ner on a highway may cause a delay in the
system's reaction to a vehicle in front of
you or may cause the system to react to a
vehicle actually in the lane next to you.
Always be ready to take action or apply the
brakes if necessary.
Active cruise control can only decelerate
the vehicle to approx. 20 mph/30 km/h. If
the system reduces vehicle speed below
20 mph/30 km/h or if DSC/ABS is engaged
while driving, the system will automatically
deactivate.
Remember, the system cannot stop
your vehicle. In addition, the system is
deactivated whenever the driver applies
the vehicle brakes, shifts the transmission
from drive/D to neutral/N, or deactivates DSC. After any deactivation, the system
will no longer automatically activate the
vehicle brakes, which means the driver
must intervene and resume manual brak-
ing. You should then reactivate the system
only when you are fully aware of the prior
speed and distance settings.<
Active cruise control may brake when you
reduce the stored desired speed; however,
the driver must constantly monitor traffic
and intervene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off,
too, and any settings you have selected are
canceled.
Behavior in curves
Because of the limited range of the system,
it is possible that in curves or on the peaks
and valleys of hilly roads, a vehicle ahead
may be recognized late, or not at all. There-
fore, it is up to the driver to select a speed
that is prudent in view of the curves and
terrain of the roadway.
In approaching a curve, it is possible that
active cruise control would react briefly to a
vehicle in the adjacent lane. In addition, the
system can sense if your vehicle is in a
curve and may not accelerate. If your vehi-
cle decelerates in either case, you can

Driving
64 choose to overcome the deceleration by
briefly pressing the accelerator pedal.
Driver interventions
Anytime the driver presses down on
the accelerator pedal, any automatic
braking action by the system is interrupted
until the pedal is fully released. After doing
this, release the accelerator and the system
again controls your cruising speed and dis-
tance setting. While driving with activated
system, resting your foot on the accelerator
pedal will cause the system not to brake
even if necessary. Be certain that floormats
or other objects on the vehicle floor do not
interfere 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 system to apply the brakes is
also limited, if you are driving down a steep
grade or when you reduce your desired
speed sharply. The system cannot stop
your vehicle. It uses only a portion of brak-
ing system capacity and does not utilize the
full capacity of the vehicle braking system.
Therefore, the system cannot decrease
your speed for large differences in speed
between your vehicle and the vehicle
ahead. Examples: during emergency brak-
ing, 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.<
Whenever active cruise control
recognizes a situation that
requires driver braking because
the system capacity has been
reached or has been exceeded,
the system alerts the driver by flashing this
symbol in the instrument cluster and
sounding a signal.
Swerving vehicles
When a vehicle moves from an adjacent
lane into your lane, active cruise control will
not recognize this vehicle until it is fully in
your lane ahead of your vehicle.
Malfunctions
If there is a malfunction, the indica-
tor lamp symbol is displayed in the
instrument cluster. Please note any
supplementary information that appears on
the Control Display.
The build-up of foreign material, e.g.,
snow, ice, dirt, road debris, etc., can lead
to reduced detection performance of active
cruise control. You should check the sen-
sor under the front bumper and clean it as
necessary prior to driving your vehicle. If
the sensor becomes covered by foreign
material or has a malfunction, it is possible
that the sensor will no longer be able to
detect vehicles in front of you. After the
system recognizes that the sensor is no
longer functional, a message is displayed
on the Control Display and an acoustic sig-
nal is emitted.

Displays in the instrument cluster
The display sequence:
>Cruising range
>Average speed
>Average fuel consumption.
Cruising range
Displays the estimated cruising range
available with the remaining fuel. The sys-
tem calculates the cruising range based on
operating conditions and the amount of fuel
remaining in the tank. The basis for the cal-
culations is the average fuel consumption
over the preceding 20 miles/30 km.
Always refuel as soon as possible
once your cruising range falls to
below 30 miles/50 km, as otherwise engine functions are not ensured and damage can
occur.<
Refueling is only registered by the com-
puter for fuel amounts above approx.
1.3 gallons/5 liters.
Average fuel consumption
The average fuel consumption is calculated
for the time during which the engine is run-
ning.
You can use the Control Display to view
your fuel consumption rate over two differ-
ent distances, refer to Computer or Trip
computer.
To reset the average fuel consumption to
zero: press the BC button in the turn signal
indicator lever for approx. 2 seconds.
Average speed
Periods with the vehicle parked and the
engine switched off are not included in the
calculations of average speed.
To reset the average speed to zero: press
the BC button in the turn signal indicator
lever for approx. 2 seconds.
