Parking assist
Rear parking assist
9 Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic signals.
The system has four ultrasonic
parking sensors in the rear bumper.
Activation
When reverse gear is engaged, the
system is ready to operate
automatically.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
Driving and operating199Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle. The interval between the
sounds becomes shorter as the
vehicle gets closer to that obstacle.
When the distance is less than
approx. 30 cm, the sound is
continuous.
Additionally, the distance to obstacles
may be shown in the Driver
Information Centre (DIC).
Deactivation
The system automatically switches
off when reverse gear is disengaged.
To switch on the system again,
engage reverse gear.
Manual deactivation is also possible by pressing r.
When the system is deactivated, the
LED in the button extinguishes.
Additionally, Park Assist Off pops-up
in the DIC when the system is
deactivated manually.
Fault
In the event of a fault in the system or if the system does not work due to
temporary conditions, e.g. ice
covered sensors, control indicator
r illuminates or a message is
displayed in the DIC.

Control indicator r 3 115.Front-rear parking assist9 Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area when driving backwards or
forwards while using parking
assist system.
The front-rear parking assist
measures the distance between the vehicle and obstacles in front and
behind the vehicle. The system gives acoustic signals and display
messages.
The system has four ultrasonic
parking sensors each in the rear and
front bumper.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency. The signal
for front obstacles sounds via the
front speakers, for rear obstacles it
sounds from the rear speakers.
Driving and operating201
The distance to a front and rear
obstacle is indicated by changing
distance lines around the vehicle.
Rear obstacles are indicated
acoustically and visually at the same
time.
Front obstacles are indicated visually
first. At distances less than 80 cm an
acoustic signal also sounds.
The distance indication in the DIC can be inhibited by vehicle messages with
a higher priority. After approving the
message by pressing SET/CLR on
the turn signal lever, distance
indication appears again.
Deactivation
The rear parking assist automatically
switches off when reverse gear is
disengaged.
The front parking assist is deactivated automatically at a speed above
7 mph.
Manual deactivation is possible by
pressing r or D briefly.
When the system is deactivated, the
LED in the button extinguishes.
Additionally, Park Assist Off pops-up
in the DIC when the system is
deactivated manually.
After a manual deactivation, the front
parking assist is activated again if
r or D is pressed or if reverse
gear is engaged.
Fault
In the event of a fault in the system or if the system does not work due to
temporary conditions, e.g. ice
covered sensors, control indicator
r illuminates or a message is
displayed in the DIC.

Control indicator r 3 115.
Advanced parking assist9 Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
advanced parking assist.
202Driving and operating
The advanced parking assist system
manoeuvres the driver into a parking slot by giving instructions in the DIC
and via acoustic signals. The driver
must control acceleration, braking,
steering and gearshifting.
The system uses the sensors of the
front-rear parking assist in
combination with two additional
sensors on both sides of the front and rear bumper.
Button D and operation logic
Advanced parking assist and front-
rear parking assist (see previous
description) are both operated by
pressing D.
Short press of D deactivates or
activates the front parking assist.
Long press of D (approx.
one second) activates or deactivates
the advanced parking assist.
Button logic to operate the systems is as follows:
● Front-rear parking assist is active: short press deactivates
front-rear parking assist.
● Front-rear parking assist is active: long press activates
advanced parking assist if a
forward gear is engaged.
● Advanced parking assist is active: short press activates
front-rear parking assist.
● Advanced parking assist is active: long press deactivatesadvanced parking assist.
● Advanced parking assist and front-rear parking assist are
active: short press deactivates
both systems.Activation
When searching for a parking slot, the
system must be activated by pressing D for approx. one second.
The system can only be activated and
can only search for a parking slot at a speed up to 18 mph.
The maximum allowed parallel
distance between the vehicle and a
row of parked cars is 1.8 metres.
Driving and operating205Basic notes on parking assist
systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and
correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Notice
The parking assist system can be
activated and deactivated by
changing the settings in the
Info-Display. If a trailer coupling is
attached, it must be selected in the
menu.
Vehicle personalisation 3 130.
Notice
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
It is possible that the sensor detects
a non-existing object (echo
disturbance) caused by external acoustical or mechanic
disturbances.
Advanced parking assist system
may not respond to changes in the
parking space after initiating a
parallel parking manoeuvre.
Notice
If engaging a forward gear and
exceeding a certain speed, the rear
parking assist will be deactivated
when the rear carrier system is
extended.
If engaging reverse at first, the
parking assist will detect the rear
carrier system and provide a buzzing
sound. Press r or D briefly to
deactivate the parking assist.
Notice
After use the advanced parking
assist requires a calibration. For
optimal parking guidance, a driving
distance of at least 22 miles,
including a number of bends, is
required.
Driving and operating207by approx. 3 metres. The height of the
zone is approx. between 0.5 metres
and 2 metres off the ground.
The system is deactivated if the
vehicle is towing a trailer.
Side blind spot alert is designed to
ignore stationary objects such as
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.
Fault
Occasional missed alerts can occur under normal circumstances.
Side blind spot alert does not operate when the left or right corners of the
rear bumper are covered with mud,
dirt, snow, ice or slush. Cleaning
instructions 3 282.
In the event of a fault in the system or
if the system does not work due to
temporary conditions, a message is
displayed in the DIC. Seek the
assistance of a workshop in case of a permanent fault.Rear view camera
The rear view camera assists the
driver when reversing by displaying a
view of the area behind the vehicle.
The view of the camera is displayed
in the Colour-Info-Display.9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view and the
advanced parking assist sensors,
e.g. below the bumper or
underneath the vehicle, are not
displayed.
Do not reverse the vehicle by only looking at the Info-Display and
check the surrounding area
behind and around the vehicle
before reversing.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged.
Functionality
The camera is mounted in the tailgate handle and has a viewing angle of
130°.
