Active cruise control*
The concept
With active cruise control you can select a
desired speed which is not only automati-
cally maintained when driving on open
roadways, but also varied to maintain a
selected distance setting as slower traffic
is encountered.
Active cruise control is a technological
advance over the familiar cruise control
and is a welcome relief from the constant
adjustment of speed that can accompany
driving in traffic on freeways or other high-
speed thoroughfares. Especially on longer
trips, the system can reduce fatigue and
tension, while increasing your enjoyment of driving. Please use it safely and responsi-
bly.
In addition to holding a steady cruising
speed, if you do encounter slower vehicles
ahead, active cruise control will, within the
scope of given possibilities, adjust your
vehicleÕs speed automatically so that you
can flow with the traffic without frequent
intervention by the driver. If, for example,
while cruising 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 between your
vehicle and the vehicle ahead. There are
four settings for distance, which is addi-
tionally speed-dependent. Based on your
selected distance setting, the system auto-
matically decreases the throttle setting and
lightly applies the brakes if necessary. The
vehicle brake lamps will automatically illu-
minate to signal a following driver to take
action. In addition, it may be necessary for
the vehicle to downshift to maintain the dis-
tance setting selected. If the vehicle ahead
speeds up or when the lane ahead
becomes clear, your vehicle will accelerate
to the speed you have selected by increas-
ing the throttle setting and shifting gears as
needed.
Active cruise control is not and must
not be used as a collision avoidance/
warning system.<
Since this active cruise control sys-
tem is a new technology and operates
differently from conventional cruise control
systems which you may be accustomed,
you are strongly urged to read all of the
pages relating to this system before use.
Pay special attention to the information
contained in the Things to know about
active cruise control section in this manual
beginning on page 62.<

The current driving speed is stored as a
desired speed and briefly displayed in the
instrument cluster, see below.
1 Desired speed store and increase
Press the lever forward:
The system adopts and stores your current
speed as a desired speed. The speedome-
ter indicates this speed.
Subsequently pressing forward increases
the desired speed to the next 5-mile place/
10 km/h.
Each time the lever is pressed forward
again, the desired speed is increased by
another 5 mph/10 km/h until a maximum of
110 mph/180 km/h is reached. The speed
then displayed is stored and reached on a
clear road.
If the system cannot be activated, the
display ACC --- mph/km/h briefly
appears in the instrument cluster. The sys-
tem may have been automatically deacti-
vated, refer to Deactivate system, or a mal-
function has occurred.
To call up Check Control messages, refer
to page 68.<
2 Desired speed store and decrease
Pull back the lever:
The current driving speed is rounded off to
the next 5-mile place/10 km/h, displayed
and stored.
Each time the lever is pulled back again,
the desired speed is decreased by another
5 mph/10 km/h until the minimum speed of
20 mph/30 km/h is reached. The speed
then displayed is stored and reached on a
clear road.
3 Deactivate system
Press the lever up or down while the sys-
tem is active. The displays in the instrument
cluster disappear. You can use the system
again as required.
In addition, the system is deactivated auto-
matically:
>When you apply pressure to the brake
pedal
>When you select the automatic trans-
mission's/SMG's neutral range N
>With the manual transmission idling
>When you deactivate the DSC Dynamic
Stability Control
>When you actuate the parking brake
during driving
>When the system reduces the speed to
below 20 mph/30 km/h due to a traffic
situation.
The system deactivates automatically
when the speed is set to below
20 mph/30 km/h. A gong sounds and a
message appears on the Control Display.
The active intervention of the driver is
required.<
When you switch off the ignition, the stored
desired speed is deleted.

Things to know about active cruise control
As with conventional cruise control
systems, active cruise control in no
way diminishes or substitutes for the
driverÕs own personal responsibility, alert-
ness and awareness in adjusting speed,
braking or otherwise controlling the vehi-
cle. The driver should decide when to use
the system on the basis of road, traffic, vis-
ibility, and weather conditions. Active
cruise control is intended for use on high-
way-type roadways where traffic is moving
relatively smoothly. Do not use this system
in city driving; 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 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, especially
when the system is actively following a
vehicle in front of you.<

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
Page 66 of 220
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.
