Driving systems
The driving systems of your vehicle are
described on the following pages:

Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed

Distance warning function* (only avail-
able with Distronic*), which warns of
stationary objects or slower moving ve-
hicles that you are closing in on too
quickly

ABC with vehicle level control systems,
with which you can change vehicle sus-
pension characteristics

Parktronic*, which assists the driver
during parking maneuvers
For information on the BAS, ABS, ESP
®,
and the electro-hydraulic brake system,
see “Driving safety systems” (
page 89).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
The use of the cruise control is recom-
mended for driving at a constant speed for
extended periods of time.
You can set or resume the 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 24).
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 constant speed.

The use of the cruise control can be dan-
gerous on winding roads or in heavy traf-
fic because conditions do not allow safe
driving at a constant speed.

The use of the cruise control can be dan-
gerous 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.

XXX Km/h
Warning!G
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.
iThe vehicle speed displayed in the speedom-
eter can briefly vary from the speed setting for
the cruise control system.
iOn uphill 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 by braking with the vehicle’s brake
system. In addition, on longer downhill grades
the automatic transmission will downshift auto-
matically.
