Driving systems
Driving systems
The following driving systems are ex-
plained on the following pages:
Cruise control and Distronic*, with 
which the vehicle can maintain a preset 
speed
Airmatic* adjusts the vehicle suspen-
sion characteristics automatically and 
controls the vehicle level
Parktronic system*, which assists the 
driver during parking maneuvers
The BAS, ABS, ESP and SBC are described 
in the “Safety and Security” section 
(
page 74).
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 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 found on the left-hand side of the 
steering column (
page 20).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must always 
remain 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.

The total load weight including vehicle oc-
cupants and luggage / cargo should not ex-
ceed the vehicle capacity weight indicated 
on the certification tag which can be found 
on the left door pillar.The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to 
load the vehicle according to the illustra-
tions shown, with the heaviest items being 
placed towards the front of the vehicle.
Always place items being carried against 
front or rear seat backrests, and fasten 
them as securely as possible.
The heaviest portion of the cargo should al-
ways be kept as low as possible since it in-
fluences the handling characteristics of 
the vehicle.
