Driving systems
The following driving systems are ex-
plained on the following pages:
Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed
Airmatic* adjusts the vehicle suspen-
sion characteristics automatically and
controls the vehicle level
Parktronic system*, which assists the
driver during parking maneuvers
The BAS, ABS, ESP and SBC are described
in the “Safety and Security” section
(
page 74).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set any speed
over 20 mph (30 km / h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column (
page 20).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must always
remain responsible for the vehicle speed
and for safe brake operation.
Only use cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.
The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.
The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.
Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

Driving systems
Parktronic system* (Parking assist)
The Parktronic system is an electronic aid
designed to assist the driver during park-
ing maneuvers. It visually and audibly indi-
cates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically ac-
tivated when you switch on the ignition
and release the parking brake. The
Parktronic system deactivates at speeds
over 11 mph (18 km / h). At lower speeds
the Parktronic system turns on again.The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors in the front bumperWarning!
G
The Parktronic system is a supplemental
system. It is not intended to, nor does it re-
place, the need for extreme care. The re-
sponsibility during parking and other critical
maneuvers always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice. See
“Cleaning the Parktronic system sensors”
(page 305).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers or the air
brakes of trucks) can cause the system to
send erratic indications, and should be tak-
en into consideration.
Warning!
G
Make sure that no persons or animals are in
the area in which you are maneuvering. You
could otherwise injure them.
230 Controls in detailDriving systemsRange of the sensors
To function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to
scratch or damage the sensors.Front sensors
Rear sensorsMinimum distance
If the system detects an obstacle in this
range, all the warning lamps come on and
you hear a warning signal. If the obstacle is
closer than the minimum distance, the ac-
tual distance might no longer be indicated
by the system.

!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The
Parktronic system will not detect such
objects at close range and damage to
your vehicle or the object may result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes or jackham-
mers) may impair the operation of the
Parktronic system.

Warning indicators
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicator for the
front area is located above the center air
vents in the dashboard. The warning indi-
cator for the rear area is integrated in the
rear trim.Front area warning indicator1Left side of the vehicle
2Right side of the vehicleEach warning indicator is divided into six
yellow and two red segments for either
side of the vehicle. The Parktronic system
is ready when the border around the indi-
cator is illuminated.
The position of the gear selector lever de-
termines which warning indicators will be
activated.
As your vehicle approaches an object, one
or more segments will come on, depending
on the distance. When the eighth segment
comes on, you have reached the minimum
distance.
Front area: An intermittent acoustic
warning will sound as the first red seg-
ment comes on and a constant acous-
tic warning lasting a maximum of
three seconds will sound for the sec-
ond red segment. The signal is can-
celed when the selector lever is placed
in positionP and the parking brake is
activated.
Rear area: An intermittent acoustic
warning will sound as the first red seg-
ment comes on and a constant acous-
tic warning lasting a maximum of
three seconds will sound for the sec-
ond red segment. The signal is can-
celed when the selector lever is placed
in position D orP and the parking
brake is activated.

Parktronic system malfunction
There is a malfunction in the Parktronic
system if the red segments of the
Parktronic system warning indicator come
on and a warning sounds. The Parktronic
system will switch itself off after
30 seconds and the indicator lamp on the
Parktronic system switch comes on.
Have the Parktronic system checked
by an authorized Mercedes-Benz Cen-
ter as soon as possible.If only the red segments of the Parktronic
system warning indicator come on and no
warning sounds, then the sensors of the
Parktronic system are dirty or malfunction-
ing. Malfunction may also be caused by in-
terference from other radio or ultrasonic
signals. The Parktronic system will switch
itself off after 20 seconds.
Clean Parktronic system sensors
(page 305).
Switch on the ignition.
or
Check Parktronic system operation at
another location to rule out interfer-
ence from outside radio or ultrasonic
signals.
