It is the driver who 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 via acoustic and visual
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.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
1.5 m. The interval between the
sounds becomes shorter as the
vehicle gets closer to that obstacle.
When the distance is less than
approximately 30 cm, the sound is continuous.
Additionally, the distance to rear
obstacles is displayed by changing
distance lines in the Driver
Information Centre with Uplevel
Display 3 92 or, depending on the
version, on the Colour Info Display
3 96.

Information Centre.
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. It informs and
warns the driver via acoustic signals
and display indication.
The system has six ultrasonic parking
sensors in both 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.
Front-rear parking assist is always
combined with advanced parking
assist, see "Advanced parking assist" section below.
Driving and operating153After a manual deactivation, the front-
rear parking assist is activated again

Information Centre.
Vehicle messages 3 98.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
the advanced parking assist.
The advanced parking assist
measures a suitable parking slot
while passing, calculates the
trajectory and automatically steers
the vehicle into a parallel or
perpendicular parking slot.
Instructions are given in the Driver
Information Centre 3 92 or,
depending on the version, on the
Colour Info Display 3 96, supported
by acoustic signals.
The driver must control acceleration,
braking and gearshifting, while
steering is done automatically.
Advanced parking assist can only be activated when driving forwards.Advanced parking assist is always
combined with front-rear parking
assist, see previous section. Both
systems use the same sensors in the front and rear bumper.
Button D and operation logic
Advanced parking assist and front-
rear parking assist both use the same
button for activation and deactivation:
A brief press of D activates or
deactivates the parking assist.
A long press of D (approx.
1 second) activates or deactivates the
advanced parking assist, see
separate description below.
Driving and operating157Deactivation by the driver or by the
system during manoeuvring will be
indicated by Parking Deactivated on
the display. Additionally, an acoustic
signal sounds.
Fault
A message appears when:
● there is a fault in the system
● the driver did not successfully complete the parking manoeuvre
● the system is not operational
● any of the deactivation reasons described above apply
If an object is detected during parking instructions, Stop is indicated on the
display. Removing the object will resume the parking manoeuvre. If the
object is not removed, the system will
be deactivated. A long press of D
will activate the system and search for
a new parking slot.Basic 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
It is possible that the sensor detects a non-existing object caused by
echo disturbance from external
acoustic noise or mechanical
misalignments (sporadic false
warnings may occur).
Make sure that the front number
plate is properly mounted (not bent
and no gaps to the bumper on the left
or right side) and the sensors are
firmly in place.
Advanced parking assist system
may not respond to changes in the
available parking space after
initiating a parking manoeuvre. The
system may recognize an entry, a
158Driving and operatinggateway, a courtyard or even a
crossing as a parking slot. After selecting reverse gear the system
will start a parking manoeuvre. Take care regarding the availability of the
suggested parking slot.
Surface irregularities, e.g. on construction zones, are not detected
by the system. The driver accepts
responsibility.
Notice
If engaging a forward gear and
exceeding a certain speed, the
parking assist will be deactivated
when the rear carrier system is
extended.
If engaging reverse for the first time,
the parking assist will detect the rear carrier system and provide an
acoustic signal. Press r or D
briefly to deactivate the parking assist.
Notice
After production, the system
requires a calibration. For optimal
parking guidance, a driving distance
of at least 6 miles, including a
number of bends, is required.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.
Side blind spot alert uses some of the advanced parking assist sensors
which are located in the front and rear
bumper on both sides 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 light.
When the system detects a vehicle in the side blind zone while driving
forwards, either while passing a
vehicle or being passed, a yellow
warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn lights,
the warning symbol B starts flashing
yellow as a warning not to change
lanes.
Notice
If the overtaking vehicle is at least
6 mph faster than the vehicle being
overtaken, the warning symbol B in
the relevant exterior mirror may not
illuminate.
Vehicle care191illuminates. For the further three
tyres, 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 the
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 3 227, and
select the appropriate setting in the
menu Tyre Load in the Driver
Information Centre, Vehicle
Information Menu 3 92 . 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.
Select:
● Light for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Max for full loading.
Tyre pressure sensor matching
process
Each pressure sensor has a unique
identification code. The identification
code must be matched to a new tyre /
wheel position after rotating the tyres
or exchanging the complete wheel set and if one or more pressure sensors
were replaced. The pressure sensor
matching process should also be
performed after replacing a spare tyre
with a road tyre containing the
pressure sensor.
The malfunction light w and the
warning message or code should go
off 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 light at the current active position
is illuminated until sensor is matched.
Consult a workshop for service. There are 2 minutes to match the first wheelposition, and 5 minutes overall to
match all four wheel positions. If it
takes longer, the matching process
stops and must be restarted.
