Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column. In order to
maintain the specified speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving at
constant speed is prevented by adverse
conditions, e.g. winding roads, dense traffic or
poor road conditions due to, e.g., snow, rain, ice
or loose surfaces. Otherwise you could lose
control of the vehicle and cause an accident as a
result.<
Manual transmission
You can shift gears while cruise control is acti-
vated. An indicator lamp notifies you that you
should shift gears when you drive for an
extended period at very high or very low engine
speeds, or the system is deactivated.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.
>Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever

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 high-
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.
Within the limits of its capability, the system
automatically adapts the car's speed to that of a
slower vehicle in front of you. You can specify
the distance to be maintained from the vehicle
in front in four stages. For safety reasons, the
distance is speed-dependent. Based on your
selected distance setting, the system automat-
ically decreases the throttle setting and lightly
applies the brakes if necessary. The vehicle
brake lamps will automatically illuminate to sig-
nal 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 trans-
mission your vehicle is equipped with, to main-
tain the distance 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 increasing the
throttle setting and shifting gears automatically
or by the driver as needed. Your selected speed
will be held when driving downhill, too.
Since this active cruise control system is a new
technology and operates differently from con-
ventional 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 System
limitations section beginning on page68.
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. An indicator lamp notifies you that you
should shift gears when you drive for an
extended period at very high or very low engine
speeds, or the system is deactivated.
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.<

Use good judgment to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.
Otherwise, an accident risk could result.<
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 idle 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 accident.<
Warning lamp
The warning lamp comes on when
active cruise control has been auto-
matically deactivated due to a driving
speed below 20 mph or 30 km/h, an application
of the parking brake 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 idle posi-
tion
>In cars with automatic transmission: when
you engage selector lever position N
>When the ignition is switched off

are currently not met. Calling up Check Control
messages, refer to page82.<
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.
When the radar sensor is not properly posi-
tioned, active cruise control cannot be activated
at all.
Malfunction
The warning lamp comes on when
the system has failed. A message
appears on the Control Display. You
can find more information starting on page81.
System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example, at a traffic light or a
parked vehicle. Also, the system does not react to oncoming traffic, pedestrians or other types
of potential traffic such as a rider on horseback.
It is also possible that the system may not
detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when
encountering any of these situations as the sys-
tem will neither automatically brake, nor provide
