236Driving and operatingfor front obstacles sounds via the
front speakers, for rear obstacles it
sounds via the rear speakers.
The system has four ultrasonic
parking sensors each in the rear and
front bumper.
Activation
When reverse gear is engaged, the
front and rear parking assist is ready
to operate.
The system is also activated
automatically at a speed up to
11 km/h.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
If r is switched off within an ignition
cycle, the front parking assist is
deactivated. If vehicle speed has exceeded 25 km/h beforehand,
parking assist will be reactivated when speed drops below 11 km/h.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind and in
front of the vehicle.
Depending on which side of the
vehicle is closer to an obstacle, you
will hear acoustic warning signals on
the respective side of 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 rear and
front obstacles is displayed by
changing distance lines in the Driver
Information Centre 3 117 or,
depending on the version, on the Info- Display 3 121.
238Driving and operatingexternal noise sources may causethe 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.
Note
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.
Note
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 gear first, the
parking assist will detect the rear
carrier system and provide a buzzing
sound. Press r briefly to
deactivate the parking assist.
Side blind spot alert
The side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
"blind spot" zone. The system
displays a visual alert in each exterior
mirror, when detecting objects that
may not be visible in the interior and
exterior mirrors.
The system's sensors are located in
the bumper on the left and right side
of the vehicle.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:
● vehicles outside the side blind zones which may be rapidly
approaching
● pedestrians, cyclists or animals
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
240Driving and operatingRear 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 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
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.
Due to the high position of the
camera, the rear bumper can be seen on the display as a guide to position.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Guiding lines
Dynamic guiding lines are horizontal
lines at one metre intervals projected
on the picture to define the distance
to displayed objects.
Trajectory lane of the vehicle is
shown in accordance with the
steering angle.
Driving and operating241Warning symbols
Warning symbols are indicated as
triangles 9 on the picture which
shows obstacles detected by the rear
sensors of the parking assist.
Additionally 9 appears on the top line
of the Info-Display with the warning to check the vehicle surrounding.
Deactivation The camera is switched off when a
certain forward speed is exceeded or
if reverse gear is not engaged for
approx. 15 seconds. Rear view
camera can be manually deactivated
in the vehicle personalisation menu in the Info-Display. Select the relevant
setting in Settings .

Fault
Fault messages are displayed with a
9 on the top line of the Info-Display.
The rear view camera may not
operate properly when:
● The surrounding area is dark.● The sun or the beam of headlights is shining directly into
the camera lens.
● Ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth.
● The tailgate is not closed correctly.
● The vehicle had a rear-end accident.
● There are extreme temperature changes.
Traffic sign assistant
Functionality The traffic sign assistant system
detects designated traffic signs via a
front camera and displays them in the
Driver Information Centre.
Vehicle care285System status and pressure warnings
are displayed by a message
indicating the corresponding tyre in
the Driver Information Centre.
The system considers the tyre
temperature for the warnings.
A detected low tyre pressure
condition is indicated by control
indicator w 3 115.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 320.
If w flashes for 60-90 seconds and
then illuminates continuously, there is
a fault in the system. Consult a
workshop.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure.
Vehicle messages 3 122.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator w illuminates. For
the further three wheels the system
remains operational.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced. For the screwed sensor: replace
valve core and sealing ring. For
clipped sensor: replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition
according to the tyre information label or tyre pressure chart 3 320, and
select the appropriate setting in the Tyre load menu in the Driver
Information Centre 3 117. This
setting is the reference for the tyre
pressure warnings.
The Tyre load menu only appears if
the vehicle is at a standstill and the parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.
286Vehicle care
Select Tyre load page under Vehicle
Information Menu ? in the Driver
Information Centre 3 117.
Select: ● Light for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Max for full load.
Tyre pressure sensor matching
process
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating
the wheels or exchanging the
complete wheel set and if one or more
tyre pressure sensors were replaced. The tyre pressure sensor matching
process should also be performed
after replacing a spare wheel with a
road wheel containing the tyre
pressure sensor.
The malfunction light w and the
warning message or code should
extinguish at the next ignition cycle.
The sensors are matched to the
wheel positions, using a relearn tool,
in the following order: left side front
wheel, right side front wheel, right
side rear wheel and left side rear
wheel. The turn signal light at the
current active position is illuminated
until sensor is matched.
Consult your workshop for service.
There are two minutes to match the
first wheel position, and five minutes
overall to match all four wheel
positions. If it takes longer, the
matching process stops and must be
restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.2. Turn the ignition on.
3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission: select neutral.
4. Press MENU on the turn signal
lever to select the Vehicle
Information Menu ? in the
Driver Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
