Driving systems
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.
