Driving systems
Introduction
This section describes the following driving
systems of your vehicle:
R Cruise control
R RACE START
R Hill-start assist system
R Parktronic system
R Rear view camera
The driving safety systems ABS, Adaptive
Brake, BAS, EBP, ESC and Trunk Wing are
described in the “Safety and security” section
( Y page 61).
Cruise control
The cruise control maintains the speed you
set for your vehicle automatically.
The use of the cruise control is recommended
for driving at a constant speed for extended
periods of time.
The currently set speed or last set speed
(“Resume” function) appears in the
multifunction display for approximately
5 seconds.
GWarning!
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 constant speed.
R 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 constant speed.
R 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.
R 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.GWarning!
The cruise control brakes automatically so
that the set speed is not exceeded.

pedal.
i On uphill grades, the 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
maintains the set speed by braking with the
vehicle’s brake system. In addition, on
longer downhill grades the transmission
will downshift automatically.

engage the electronic parking brake.
The cruise control also switches off
automatically when
R the vehicle speed falls below 20 mph
(30 km/h)
R the ESC is in operation
R the ESC is switched off with the ESC switch
Rthe ESC has switched off due to a
malfunction
R you shift the transmission into neutral
position N while driving
An acoustic warning will sound. Observe
additional messages in the multifunction
display that may appear.
Depressing the accelerator pedal does not
deactivate the cruise control. After a brief
acceleration (e.g. for passing), the cruise
control will resume the last set speed.
Changing the set speed GWarning!
Keep in mind that it may take a brief moment
until the vehicle has made the necessary
adjustments.
Increase or decrease the set vehicle speed to
a value that the prevailing road conditions and
legal speed limits permit. Otherwise, sudden
and unexpected acceleration or deceleration
of the vehicle could cause an accident and/
or serious injury to you and others.
You can increase or decrease the set speed
in 1 mph (Canada: 1 km/h) increments or in
5 mph (Canada: 10 km/h) increments.
When you use the cruise control lever to
decelerate, the brake system will brake the
vehicle automatically if the engine’s braking
power does not brake the vehicle sufficiently.
XIncreasing: Lift the cruise control lever in
direction of arrow : and hold it up until
the desired speed is reached.XDecreasing: Press the cruise control lever
in direction of arrow ; and hold it down
until the desired speed is reached.XRelease the cruise control lever.

Hill-start assist system
On uphill grades, the hill-start assist system
maintains the pressure in the brake system
for approximately 1 second after you have
released the brake pedal. Therefore, you can
start off smoothly without the vehicle moving
immediately after releasing the brake pedal.
GWarning!
The hill-start assist system is not designed to
function as a parking brake. It does not
prevent the vehicle from moving when parked
on an incline.
Always engage the electronic parking brake
in addition to shifting the transmission into
park position P.

Parktronic system
The Parktronic system is an electronic
parking aid with ultrasonic sensors designed
to assist the driver during parking maneuvers.
The Parktronic system indicates the relative
distance between the vehicle and an obstacle
visually and audibly.
The Parktronic system is activated
automatically when
Ryou switch on the ignition
and
Ryou release the electronic parking brake
or
Ryou start the engine
and
Rshift the transmission into drive position
D, reverse gear R, or neutral position N
The Parktronic system deactivates at speeds
above approximately 11 mph (18 km/h). At
lower speeds, the Parktronic system
activates again.
The Parktronic system also deactivates when
you shift the transmission into park position
P or engage the electronic parking brake and
turn off the engine.
The Parktronic system monitors the
surroundings of your vehicle with four
sensors in the front bumper and four sensors
in the rear bumper.
Example illustration, sensors in the front bumper
To function properly, sensors : must be free
of dirt, ice, snow and slush. Clean
sensors : regularly. Be careful not to
scratch or damage sensors :, see “Cleaning
the Parktronic system sensors”
(Y page 357).
GWarning!
The 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.
GWarning!
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
! Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts,
elevated crossbars or road curbs). Such
objects may not be detected by the system
and can damage the vehicle.
During parking maneuvers, pay special
attention to objects located above or below
the height of the sensors (e.g. street curbs,
painted posts, or trailer hitches etc.). The
Parktronic system will not detect such
objects at close range and damage to your
vehicle or the object may result.
! Ultrasonic signals from outside sources
(e.g. truck air brakes, car wash, or
jackhammers) may impair the operation of
the Parktronic system.
