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.


Rear Parking Assist*, with which you
can assist your parking maneuvers.
The BAS, ABS, ESP, 4-ETS and EBB driving
systems are described in the “Safety and
Security” section (
page 74).
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
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 found on the left-hand side of the
steering column (
page 23).
iThe cruise control should not be acti-
vated during-off road driving.
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.

(“Resume” function)

Briefly push the cruise control lever to
position4.
Cruise control will resume the last set
speed.

Remove your foot from the accelerator
pedal.
iDepressing the accelerator pedal does
not deactivate the cruise control. After
brief acceleration (e.g. for passing), the
cruise control will resume the last
speed set.
iWhen you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the engine’s
braking power does not brake the vehi-
cle sufficiently.
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to preset
speed could endanger yourself and others.

172 Controls in detailDriving systemsRear Parking Assist*
The Rear Parking Assist system is an elec-
tronic aid designed to assist the driver dur-
ing parking maneuvers. It visually and
audibly indicates the relative distance be-
tween the rear of the vehicle and an obsta-
cle.
The Rear Parking Assist system is auto-
matically activated when you switch on the
ignition and shift the gear selector lever to
positionR.The Rear Parking Assist system monitors
the rear area of your vehicle by means of
four sensors in the rear bumper.
1SensorsWarning!
G
Rear Parking Assist (rear Parktronic) is a
supplemental system. It is not intended to,
nor does it replace, the need for extreme
care. The responsibility during parking and
other critical maneuvers always rests with
the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or
street curbs). Such objects may not be de-
tected by the system and can damage the
vehicle.
The operational function of the Rear Parking
Assist can be affected by dirty sensors, es-
pecially at times of snow and ice. See
“Cleaning the Rear Parking Assist sensors”
(page 247).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers or the air
brakes of trucks) can cause the system to
send erratic indications, and should be tak-
en into consideration.Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

173 Controls in detail
Driving systems
Range of the sensors
To function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to
scratch or damage them.Minimum distance
The minimum distance between the sen-
sors and an obstacle is approximately
20 in (50 cm). If you encounter an obstacle
in this range, all the warning lamps come
on and you hear a warning signal. If the ob-
stacle is closer than the minimum dis-
tance, the actual distance may no longer
be indicated by the system.
Center
approx. 59.1 in (150 cm)
Corners
approx. 40 in (100 cm)
!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The Rear
Parking Assist system will not detect
such objects at close range and dam-
age to your vehicle or the object may
result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes or jackham-
mers) may impair the operation of the
Rear Parking Assist system.
