Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:
Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed
Airmatic DC* adjusts the vehicle sus-
pension characteristics automatically
and controls the vehicle level
Parktronic system*, which assists the
driver during parking maneuvers
For information on BAS, ABS, electrohy-
draulic brake system and ESP
® driving sys-
tems, see “Driving safety systems”
(
page 92).
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 or resume
cruise control at any speed above 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 on the left-hand side of the steering
column (
page 22).
Warning!
G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must remain at
all times responsible for the vehicle speed
and for safe brake operation.
Only use the 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 the cruise control when driv-
ing 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.

that the set speed is not exceeded.
Keep in mind that the cruise control is a
convenience system designed to assist the

operation.
iOn uphill or downhill grades, the cruise
control may not be able to maintain the
set speed. Once the grade eases, the
set speed will be resumed.
On downhill grades, the cruise control
maintains the set speed with active
braking action.
In addition, on longer downhill grades
the automatic transmission will auto-
matically downshift.
