244 Controls in detailDriving systemsThe driving system of your vehicle is
described on the following pages:

Cruise control, with which the vehicle
can maintain a preset speed.
The BAS, ABS and ESP driving systems are
described in the “Safety and Security” sec-
tion (page 80).
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 over 25 mph (40 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.

transmitter
COMAND*, radio and telephone*Telephones and two-way radios
Radio transmitters, such as a portable tele-
phone or a citizens band unit should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.

structions regarding use of an external an-
tenna.

lapsible tire are different from those of the
road wheels. As a result, the vehicle han-
dling characteristics change when driving
with a spare wheel with collapsible tire

only be used temporarily, and should be re-
placed with a regular road wheel as quickly
as possible.
