Audible signals
The interval between the acoustic signals becomes shorter as the clearance is
reduced. A continuous tone sounds from a distance of approx. 30 cm - danger
area. From this moment on do not continue driving!
Towing a trailer
On vehicles equipped with a factory-fitted towing device, only system areas
A
and
B
» Fig. 136 are active when towing a trailer.
Note
■
If with Version 3 vehicles not all fields around the vehicle are active after ac-
tivation the vehicle should be moved forwards or backwards.■
The signal tones for front obstacle recognition are factory-set to be higher
than for rear obstacle recognition.
■
The sound of the park-assist can be adjusted via the MAXI DOT display in the
Assistants menu option » page 47.

Message: Look! Safe to move?
An area without detected obstacles is shown as a transparent segment.
An obstacle which is currently outside of the collision area is shown by the
yellow segment
An obstacle in the collision zone is shown as an orange-coloured segment.
Stop driving in the direction of an obstacle!
Activation/deactivation
Read and observe
and on page 147 first.
The system is automatically activated by selecting reverse gear or pressing
the symbol button
» Fig. 136 on page 147 .
This is confirmed by a short acoustic signal ( the symbol in the button is lit).
On vehicles with Version 1, the system can be deactivated by moving out of re-
verse gear.
For vehicles with the Version 2 and 3 the system is automatically deactivated
by pressing the symbol key or at a speed over 15 km / h (the symbol
in the
button goes out).
Fault display
If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. The fault is
also indicated by the symbol flashing in the button. Seek help from a spe-
cialist garage.
Note
The system can only be activated with the symbol key at a speed of below
15 km / hr. ABC148Driving
WARNING (Continued)■During a parking manoeuvre on loose or slippery surfaces (gravel, snow,
ice, etc.) you may stray from the calculated road because of the surface
conditions. Therefore we suggest that you do not use the system in such
situations.■
External noise sources may affect the signals of the system sensors. Un-
der adverse conditions, this may cause objects or people to not be recog-
nised by the system.
CAUTION
■ If other vehicles are parked behind the kerb or on it, the system can also
guide your vehicle beyond the kerb or onto it. Ensure that the wheels or the
wheel rims of your vehicle are not damaged and if necessary intervene in time.■
Under certain circumstances, surfaces or structures of certain objects such
as wire mesh fences or powder snow cannot be recognised by the system.
■
Under adverse weather conditions (heavy rain, water vapour, very low or
high temperatures etc.), the system function may be limited - “incorrect recog-
nition of obstacle”.
CAUTION
The correct evaluation of the parking space and the parking procedure de-
pends on the circumference of the wheels on the vehicle.■
The system only works correctly if the vehicle is fitted with the wheel size
approved by the manufacturer.
■
Do without the use of the system if snow chains or a spare wheel is moun-
ted.
■
If wheels other than those approved by the manufacturer are mounted, the
resulting position of the vehicle in the parking space can differ slightly. This
can be avoided by readjusting the system at a specialist garage.
Note
We recommend performing the parking at a safe speed to about 5 km / h.
Functioning
Read and observe
and on page 150 first.
Basic system operations
› The measurement and evaluation of the size of parking spaces when driving.
› The determination of the correct position of the vehicle for parking.
› The calculation of the line on which the vehicle drives backwards into the
parking space or forwards from the parking space.
› Automatic rotation of the front wheels during the parking.
The display of the instrument cluster (hereinafter only in the display) informa-
tion and system messages are displayed.
When the system is activated, the warning light lights up
» Fig. 141 on
page 151 -
.
The traction control system (TCS) must always be switched on when parking.

The search area for the parking space on the driver's side is automatically indi-
cated on the display.
Activate the turn signal on the driver's side if you wish to park on this side of
the road. In the display the search area for the parking space is indicated on
the driver's side.
151Assist systems
For stubborn dirt, agents specifically intended for this purpose are to be used.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such areas.
Give the vehicle a good rinse after washing it and dry it off using a chamois
leather.WARNINGProtect your hands and arms from sharp-edged metal parts when cleaning
the under floor or the inside of the wheel housings or the wheel trims – risk
of cuts!
CAUTION
■ Only apply slight pressure when cleaning the vehicle's paintwork.■Do not wash your vehicle in bright sunlight – risk of paint damage.
Automatic car wash systems
Read and observe
and on page 169 first.
The usual precautionary measures must be taken before washing the vehicle
in an automatic car wash system (e.g. closing the windows and the sliding/tilt-
ing roof etc.).
If your vehicle is fitted with any particular attached parts, such as a spoiler,
roof rack system, two-way radio aerial etc., it is best to consult the operator of
the car wash system beforehand.
After an automatic wash with wax treatment, the lips of the wipers should be
cleaned with cleaning agents specially designed for the purpose, and then de-
greased.
CAUTION
Fold in the exterior mirrors to prevent damage before washing the vehicle in
an automatic car wash system. Never manually fold in electric exterior mirrors -
always use the electric controls.Washing with a high-pressure cleaner
Read and observe
and on page 169 first.
When washing the vehicle with a high-pressure cleaner, the instructions foruse of the equipment must be observed. This applies in particular to the pres-
sure used and to the spraying distance .
Maintain a sufficiently large distance to the parking aid sensors and soft mate-
rials such as rubber hoses or insulation material.
CAUTION
■ If washing the vehicle in the winter using a hose or high-pressure cleaner,
ensure that the jet of water is not aimed directly at the locking cylinders or the
door/panel joints – risk of freezing!■
To avoid damaging the parking aid sensors while cleaning with high-pressure
cleaners or steam jets, the sensors must only be directly sprayed for short pe-
riods while a minimum distance of 10 cm must be observed.
