Braking sensation
>If you step on the brake pedal while the sys-
tem is braking, pedal sensation will be
slightly different from the usual.
>Possible noises during automatic braking
are normal.
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you
drive at very low engine speeds for an extended
period.
Range of applications
The minimum desired speed is 20 mph or
30 km/h, the maximum desired speed is
110 mph or 180 km/h.
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. Otherwise, driving situations could
result that pose the risk of accidents.<

Storing current speed
Briefly push lever, arrow1, or pull lever, arrow 2,
at a driving speed of more than approx. 20 mph
or 30 km/h.
The car's current speed is stored. It is displayed

ment cluster.

Deactivating cruise control
Press the lever upward or downward, arrow3.
The displays on the speedometer disappear.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When the speed is reduced to below
20 mph or 30 km/h due to a traffic situation
>When you switch gears very slowly or shift
to neutral in cars with manual transmission
>When you select the automatic transmis-
sion's neutral position N
>When you activate the Dynamic Traction
Control DTC
>When you deactivate the Dynamic Stability
Control DSC
>When DSC or ABS is intervening
>When the system does not recognize any
objects for a longer period of time, e.g. on
infrequently traveled roads without a shoul-
der or guard rails, or if the radar sensor is
covered with dirt, refer to page68
>When you apply the parking brake
When the system is deactivated, you
must brake the vehicle yourself and/or
maneuver as necessary; otherwise, there is a
risk of accidents.<
Warning lamp
The warning lamp comes on when
active cruise control has been auto-
matically deactivated, for example
due to a driving speed below 20 mph or 30 km/
h or a DSC intervention. A message appears on
the Control Display.
Resuming stored desired speed and
distance
Briefly press the button, arrow 4.
The stored speed and distance are regained
and maintained.
In the following instances, the stored speed is
deleted and can no longer be resumed:
>When driving stability control systems are
intervening
>In cars with manual transmission: when you
shift gears very slowly or shift to neutral
>In cars with automatic transmission: when
you engage selector lever position N
>When the ignition is switched off

The indicator lights up as soon as the sys-
tem is activated.
4Selected desired speed is temporarily dis-
played
If --- mph or --- km/h temporarily appears
in the instrument cluster display, it is pos-

Warning lamps
The indicator2 flashes in red;
a signal sounds.
The system indicates that you
must brake and/or maneuver the
vehicle yourself. Active cruise con-
trol cannot automatically restore the distance to
the vehicle ahead.
This indicator does not release you from your
responsibility to adapt your desired speed and
driving style to prevailing driving conditions.
The indicator 2 flashes in yellow.
The prerequisites for operating
active cruise control are not met,
e.g. as a result of ABS or DSC
interventions. Active cruise control
is deactivated. You can reactivate the system, if
desired, by tapping or pulling the lever when
road and traffic conditions permit. It is not pos-
sible to resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead
may be restricted as a result of heavy rain, dirt,
snow or ice. If necessary, clean the radar sensor
located in the front bumper, see arrow. Be sure
to use particular care when removing any layers
of snow or ice from the sensor.
The system cannot be activated if the sensor is
incorrectly aligned.
