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

Cruise control (page 197), with
which the vehicle can maintain a preset
speed.

Rear Parking Assist (page 200) and
rear view camera (
page 203), which
serve as parking aid.
For information on the ABS, BAS, ESP
®,
4-ETS, and EBB driving systems, see “Driv-
ing safety systems” (
page 88).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
The use of the cruise control is recom-
mended 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 found on the left-hand side of the
steering column (
page 24).
iThe cruise control should not be activated
during-off road driving.
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
dangerous on winding roads or in heavy
traffic because conditions do not allow
safe driving at a steady speed.

The use of the cruise control can be
dangerous 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
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.

Briefly push the cruise control lever in
direction of arrow3.
The cruise control is canceled. The last
speed set is stored for later use.Setting a higher speed
iOn uphill or downhill grades, the cruise
control may not be able to maintain the set
speed. Once the grade eases, the set speed will
be resumed.
!Moving the gear selector lever to neutral
positionN while driving also cancels the cruise
control. However, the gear selector lever should
not be moved to neutral positionN while driving,
except to coast when the vehicle is in danger of
skidding (e.g. on icy roads).
iThe last stored speed is canceled when you
turn off the engine.
Warning!G
If you increase the vehicle set speed, keep in
mind that it may take a brief moment until
the vehicle has reached the set speed.
Increase the vehicle set speed to a value
that the prevailing road conditions and legal
speed limits permit. Otherwise, sudden and
unexpected acceleration of the vehicle
could cause an accident and/or serious in-
jury to you and others.

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 automatically
downshift if the engine’s braking power does not
brake the vehicle 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 the
preset speed could cause an accident
and/or serious injury to you and others.

Driving systems
Rear Parking AssistThe Rear Parking Assist system is an
electronic aid designed to assist the driver
during parking maneuvers. It visually and
audibly indicates the relative distance
between the rear of the vehicle and an
obstacle.
The Rear Parking Assist system is
automatically activated when you

switch on the ignition
and

move the gear selector lever to reverse
gearR
Warning!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 remains
with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Rear Parking
Assist can be affected by dirty sensors,
especially at times of snow and ice. See
“Cleaning the Rear Parking Assist sensors”
(
page 318).
Interference caused by other ultrasonic
signals (e.g. working jackhammers, car
wash, or the air brakes of trucks) can cause
the system to send erratic indications, and
should be taken into consideration.
Warning!G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

Sensors
Minimum distance
If the system detects an obstacle in this
range, all the distance segments in the
warning indicator (
page 202) illuminate
and you hear a warning signal. If the
obstacle is closer than the minimum dis-
tance, the actual distance may no longer
be indicated by the system.Warning indicator
Visual signals indicate to the driver the
relative distance between the sensors and
an obstacle.
The warning indicator is located next to the
tailgate.
Warning indicator
1Distance segments
2Readiness indicatorThe warning indicator is divided into four
yellow, and two red distance segments1.
The Rear Parking Assist system is ready
when you hear a signal and the readiness
indicator2 is illuminated.
As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the sixth
distance segment illuminates, you have
reached the minimum distance.
An intermittent acoustic warning will
sound when the fourth yellow distance
segment illuminates. This signal quickens
with each additional distance segment
illuminated. When all distance segments
illuminate, the acoustic warning becomes
a constant signal. The signal is canceled
when the gear selector lever is moved to
drive positionD or park positionP.

soon as possible.
Rear view camera
Warning!G
The rear view camera is only an aid and may
display obstacles from a distorted perspec-
tive or inaccurately, or may not display ob-
stacles at all. The rear view camera does not
relieve you of the responsibility to be cau-
tious, take care and pay careful attention.
The rear view camera may not show objects
which are

very close to the rear bumper

under the rear bumper

under the spare wheel

You are responsible for safety at all times
and must continue to pay attention to the
immediate surroundings when parking and
maneuvering. This includes the area behind,
in front of and beside the vehicle. Otherwise
you could endanger yourself or others.
Warning!G
Make sure that no persons or animals are in
or near the area in which you are
parking/maneuvering. Otherwise, they
could be injured.
Warning!G
The rear view camera either will not function
or will not function to its full capability if

the tailgate is open

it is raining very hard, snowing or foggy

it is night or you are parking/maneuver-
ing your vehicle in an area where it is
very dark
