Rear parking aid*
The parking aid provides a warning of obstacles behind the vehicle.
The audible parking aid determines the distance between the rear bumper and an
obstacle located behind the vehicle with the aid of ultrasound sensors. The tones
of the parking aid can be adapted in the menu of the information display*
⇒ page 23. The sensors are integrated in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle (area
⇒ fig. 124 ). The interval between the warning signals becomes shorter as the
clearance is reduced.
A continuous tone sounds from a clearanc e of just 30 cm (Bereich ) - danger
area. You should not reverse any further after this signal sounds! If the vehicle
is equipped with a factory-fi tted towing device*, the border of the danger area
starts - continuous tone - 5 cm further behind the vehicle. The vehicle can be
extended through an installe d detachable towing device.
On vehicles equipped with a factory-fitted radio* or navigation*, the distance to the
obstruction is shown graphically on the disp lay. On vehicles with a factory-fitted
towing device, the sensors are deactivated when towing a trailer. The driver is also
informed of the radio* or the navigation* by a graphic display (vehicle towing a
trailer) on the display. The radio* or navi gation*, which is factory-fitted, can be set
so that the play function volume decrea ses when activating the parking aid, see Owner's Manual radio* or navigation*. This
improves the audibility of the parking
aid.
Activating
The parking aid is activated automatically when reverse gear is engaged and the
ignition is turned on. This is conf irmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.
WARNING
•The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when parking the
vehicle or carrying ou t similar manoeuvres.
•You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin po st, trailer drawbar etc., behind your
vehicle. Such an obstacle might not be within the range detected by the
sensors.
•Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the
parking aid.
Note
•The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fi tted towing device*).
•If a warning signal sounds for about 3 seconds after switching the ignition on
and engaging reverse gear, and there is no obstacle close to your car, this indicates
a system fault. Have the fault rectified by a specialist workshop.
•The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
•If the parking aid is activated and the selector lever of the automatic gearbox is
in the position , warning signal indicates interruption (vehicle can no longer
move).

Front and rear parking aid*
The parking aid provides a warning of obstacles in front and behind
the vehicle.
The audible parking aid determines the distance between the front or rear bumper
and an obstacle with the aid of ultrasound sensors. The sensors are integrated in the
front and rear bumper. The signal tones for the front parking aid sound higher as
standard than for the rear parking aid. The tones of the parking aid can be adapted
in the menu of the information display* ⇒page 23.
Range of sensors
The distance warning begins at a distance of about 120 cm from the obstacle in
front of the vehicle (area ⇒fig. 126 ) and about 160 cm from the obstacle behind the vehicle (area
⇒page 115, fig. 124). The interval between the
warning signals becomes shorter as the clearance is reduced.
A continuous tone sounds from a clearanc e of just 30 cm (Bereich ) - danger
area. You should not reverse any further after this signal sounds! If the vehicle
is equipped with a factory-fitted towing device*, the border of the danger area
starts - continuous tone - 5cm further behind the vehicle. The vehicle can be
extended through an installed detachable towing device.
On vehicles equipped with a fa ctory-fitted radio* or navigation*, the distance to the
obstruction is shown graphically on the di splay. On vehicles with a factory-fitted
towing device, the rear sensors are deactivated when towing a trailer. The driver is
also informed of the radio* or the navigation* by a graphic display (vehicle towing
a trailer) on the display. The radio* or navi gation*, which is factory-fitted, can be set
so that the play function volume decreases when activating the parking aid, see
Owner's Manual radio* or navigation*. Th is improves the audibility of the parking
aid.
Activating
The parking aid is activated when the reverse gear is engaged and the ignition is
turned on or by pressing the button ⇒fig. 125 - the symbol
lights up in the
button. The activation is confirmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated after pressing the button
⇒ fig. 125 or at a speed
of more than 10 km/h - the symbol in the button is no longer illuminated.

•The parking aid is not a substitute fo r the driver paying proper attention
and it is always the driver's responsibility to take care when reversing the
vehicle or carrying out similar manoeuvres.

Park Assist*
Description and important information
The park assist assists you when parkin g in a suitable parallel parking place
between two vehicles or behind a vehicle.
The park assist automatically searches fo r suitable parking spaces after switching
on the ignition and when driving up to 30 km/h.
During the parking procedure the park assist only takes over the steering move-
ments, the pedals continue to be operated by the driver.
Function of the system is based on:
•Length and depth measurement of the parking spaces when driving
•Evaluation of the size of the parking space
•Definition of the correct position of the vehicle for parking
•Calculating the line on which the vehi cle drives backwards into the parking
place
•Actuation of the steering force assistance , automatic spinning of the wheels of
the front axle when parking.
WARNING
The park assist does not take away th e responsability from the driver when
parking.
•Pay particular attention to small chil dren and animals as they would not
be recognised by the sensors of the parking aid.
•Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the park assist or the parking aid. Thus,
these objects or people who wear such clothing are not recognised by the
sensors of the parking aid.
•The external sound source of the park assist and the parking aid can be
disruptively influenced and under unfavourable conditions, objects or
people cannot be recognised by the sensors of the parking aid.
Caution
•If other vehicles are parked behind or on the kurb, th e park assist guides your
vehicle beyond the kurb or onto it. Make su re that the wheels or the wheel rims of
your vehicle are not damaged and if necessary intervene in time.
•You should satisfy yourself before parking that there is no small obstacle, such
as a rock, thin post, trailer drawbar etc., in front or behind your vehicle. Such an
obstacle might not be within the range detected by the sensors.
•Under certain circumstances, surfaces or structures of certain objects such as
wire mesh fences, powder snow etc..., cannot be recognised by the system.
•The evaluation of the parking place an d the parking procedure depends on the
circumference of the wheels. The system does not function correctly if your vehicle
is mounted with wheels of non-permissible size, snow chains or a temporary spare
wheel (in order to reach the nearest work shop). If the tyres other than those
excepted by the manufacturer are mounted, the resulting position of the vehicle in

the parking place can differ slightly. This can be avoided through new calibration of
the system in a specialist garage.
•The accuracy of the evaluation for the parking place can be influenced by the
incorrectly determined outside temperature if the later is influenced by the thermal
radiation of the engine i.e for stop and go in a traffic jam.
•In order to avoid damaging the sensor s while cleaning with high-pressure
cleaners or steam jets, the sensors must on ly be directly sprayed for short periods
while a minimum distance of 10 cm must be observed.
Note
•A component of the park assist is the front and rear parking aid*.
•The electronic stability programme (ESP) must always be switched on for the
parking procedure.
•Only the front parking aid operates if yo u are towing a trailer (applies only to
models which feature a factory-fitted towing device*). This is why it is not possible
to park backwards with the help of the park assist when towing a trailer.
•The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
Switch on display of the park a ssist in the information display*
Switch on display of the park assist in the information display*
– Press the button ⇒fig. 127 .
– Drive past the parking row up to maximum 30 km/h and with a distance of 0.5 m to 1.5 m ⇒fig. 128 .
Operate the turn signal for the driver's side if you wish to park on this side of the
road. In the information display* the search area for the parking place is indicated
on the driver's side.
If the button is pressed above a speed of 30 km/h, the display appears in the display
of the instrument cluster as soon as you drive slower than 30 km/h.
Note
•If the park assist is switched on, a yell ow warning light lights up in the button.
•The search for suitable parking places is automatic after switching on the igni-
tion at speeds of more than 30 km/h. Sear ching for a parking place is performed at
the same time on the driver and front passenger side.
•If the sensors find a suitable parking place, they store its parameters until
another suitable parking place has been fo und or until a distance of 10 m had been
driven after finding the parking place. This is why it is possible to switch on the park
assist after driving past the driving place; on the information display* appears the
information if this parking space is suitable for parking.
