Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:
Cruise control, with which the vehicle
can maintain a preset speed
Parktronic*, which serves as a parking
assistant.
For information on the BAS, ABS, and ESP
driving systems, see “Driving safety sys-
tems” (
page 84).
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.
CLK 320/CLK 55 AMG:
You can set or resume cruise control at any
speed over 20 mph (30 km/h).
CLK 500:
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
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must remain at all
times 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.
