Active cruise control*
The concept
With active cruise control, you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting 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 free-
ways or other high-speed thoroughfares. Espe-
cially on longer trips, 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 the scope of given
possibilities, adjust your vehicle's speed auto-
matically so that you can flow with the traffic
without having to make constant adjustments.
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 dis-
tance, which are additionally speed-dependent.
Based on your selected distance setting, the
system automatically decreases the throttle
setting and lightly applies the brakes if neces-
sary. The vehicle brake lamps will automatically
illuminate to signal a following driver to take
action. In addition, it may be necessary for the
vehicle or the driver to downshift, depending on
the kind of transmission your vehicle is
equipped with, to maintain the distance setting
selected. If the vehicle ahead speeds up or
when the lane ahead becomes clear, your vehi-
cle will accelerate to the speed you have
selected by increasing the throttle setting and
shifting gears automatically or by the driver as
needed.

Driving
60 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 differ-
ently from conventional cruise control systems
which you may be accustomed to, 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 page62.<
Vehicles with manual transmission
You can use the system in the 2nd to 6th gear
within a normal engine speed range and also
change gears. Continuous operation at very
high or very low engine speeds is not possible.
In this case the driver is asked to shift or the
system deactivates itself.
Vehicles with SMG
Continuous operation at very high engine
speeds is not possible in the Sequential mode.
In this case the driver is asked to shift or the
system deactivates itself.
In the Drive mode, the SMG acts similarly to the
automatic transmission in the D position.

Adjust your desired speed to the traffic
conditions and remain ready to brake at
all times. Great differences in speed to the vehi-
cles driving ahead, e. g. when quickly approach-
ing a truck or when another vehicle swerves into
your lane, cannot be compensated for by the
system.<

The system requests that you
intervene by braking or with an
evasive maneuver. The display 2
flashes red and a signal sounds.
The active cruise control cannot
automatically restore the distance to the vehicle

now only intervenes by braking.
Desired speed, store and increase
Press the lever forward 1 at a driving speed of
more than approx. 20 mph/30 km/h:
The system applies and stores your current
speed as a desired speed. This speed is indi-
cated on the speedometer and displayed briefly
in the instrument cluster.
Subsequently pressing forward increases the
desired speed to the next multiple of 5 mph/
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 achieved, provided that
the road is clear.
If the display ACC --- mph/km/h briefly
appears in the instrument cluster, it might
be that conditions necessary for operation are
not currently being met.
To call up Check Control messages, refer to
page67.<
Desired speed, store and decrease
Pull back the lever 2:
The current driving speed is rounded off to the
next multiple of 5 mph/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 achieved, provided that the road is
clear.
Deactivate system
Press the lever up or down while the system is
active 3. The displays in the instrument cluster
disappear. You can use the system again as
required.
In addition, the system is deactivated automati-
cally:
>When you apply pressure to the brake pedal
>When you select the automatic transmis-
sion's/SMG's neutral position N
>When the manual transmission is shifted
into neutral
>When you deactivate the DSC Dynamic
Stability Control
>When you actuate the handbrake during
driving
>When the system reduces the speed to
below 20 mph/30 km/h due to a traffic situ-
ation
The system deactivates automatically
when the speed is set to below 20 mph/
30 km/h. An acoustic signal sounds and a mes-
sage 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 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
highway-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, 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 inter-
changes, 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.<

Driving
64
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 distance 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 accelera-
tor 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, particu-
larly 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 braking 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 braking,
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 instru-
ment cluster and sounding a signal.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not rec-
ognize this vehicle until it is fully in your lane
ahead of your vehicle.
Malfunction
The indicator lamp lights up and a mes-
sage appears on the Control Display.
The build-up of foreign matter, e. g.,
snow, ice, dirt, road debris etc., can lead to
reduced detection performance of active cruise
control. You should check the sensor under the
front bumper and clean it as necessary prior to
driving your vehicle. If the sensor becomes cov-
ered by foreign matter 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 func-
tional, a message is displayed on the Control
Display and an acoustic signal is emitted.
When the system does not recognize any
objects, e.g. on infrequently traveled roads
without a shoulder or guard rails, the system
can automatically deactivate temporarily.
