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

Cruise control, with which the vehicle
can maintain a preset speed
For information on the BAS, ABS and ESP
®,
see “Driving safety systems” (
page 82).
Cruise control
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 the
cruise control at 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 on the left-hand side of the steering
column (
page 30).
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 advisable to
travel at a steady 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 steady 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
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.

cept to coast when the vehicle is in danger of
skidding (e.g. on icy roads).
