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* (Canada only), which
serves as a parking assistant.
For information on the BAS, ABS, and ESP
®
driving systems, see “Driving safety sys-
tems” (
page 87).
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 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.

266 Controls in detailDriving systems1Set current or higher speed
2Set current or lower speed
3Cancel cruise control
4Resume to last set speed
Setting current speed

Accelerate or decelerate to the desired
speed.

Briefly lift1 or depress2 the cruise
control lever (
page 266).
The current speed is set.

Remove your foot from the accelerator
pedal.
Cruise control is activated.The selected speed appears in the multi-
function display for approximately five sec-
onds, and the corresponding speedometer
segments from the selected speed to the
vehicle maximum speed are illuminated.
Warning!
G
Cruise control brakes automatically so that
the set speed is not exceeded. The brake
pedal depresses when the cruise control en-
gages the brakes.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
- your foot could become caught.
Keep in mind that cruise control is a conve-
nience system designed to assist the driver
during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
iOn uphill or downhill grades, cruise
control may not be able to maintain the
set speed. Once the grade eases, the
set speed will be resumed.
On downhill grades, the cruise control
will hold the set speed with braking
from the vehicle’s brake system.
In addition, on longer downhill grades
the automatic transmission will auto-
matically downshift.

The segments in the multifunction dis-
play (page 266) go out, and an
acoustic warning sounds.
!Moving gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
positionN while driving except to coast
when the vehicle is in danger of skid-
ding (e.g. on icy roads).iDepressing the accelerator pedal does
not deactivate cruise control. After
brief acceleration (e.g. for passing),
cruise control will resume the last
speed set.

(“Resume” function)

Briefly push cruise control lever to
position4 (
page 266).
The cruise control resumes the last set
speed.

Remove your foot from the accelerator
pedal.
The selected speed appears in the multi-
function display for approximately five sec-
onds, and the corresponding speedometer
segments from the selected speed to the
vehicle maximum speed are illuminated
(
page 266).
iWhen you use the cruise control lever
to decelerate, the brake system will
automatically brake the vehicle 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 pre-
set speed could cause an accident and/or
serious injury to you and others.

Driving systems
Parktronic system (Parking assist)*, Canada only
The Parktronic system is an electronic aid
designed to assist the driver during park-
ing maneuvers. It visually and audibly indi-
cates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically ac-
tivated when you switch on the ignition
(
page 34) and placed the gear selector
lever in positionD,R,orN.The Parktronic system deactivates at
speeds over approximately 11 mph
(18 km/h). At lower speeds the Parktronic
system turns on again.
The Parktronic system also deactivates
when you place the gear selector lever in
positionP.
The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors in the front bumper
Warning!
G
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 road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice, see
“Cleaning the Parktronic system*
(Canada only) sensors” (
page 369).
Interference caused by other ultrasonic sig-
nals (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.
