222 Controls in detailDriving systemsThe following driving systems are
explained 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 the BAS, ABS, ESP
® and
electro-hydraulic brake system, see
“Driving safety systems” (
page 84).
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 always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it ad-
visable 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.

The cruise control brakes automatically so
that the set speed is not exceeded.
Keep in mind that the cruise control is a con-
venience system designed to assist the driv-
er during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake 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 trans-
mission will automatically downshift.
