Optical Parking Assistant (hereinafter only as a system) supports the driver when
parking and manoeuvring.
The display of factory-installed navigation system shows the area behind the ve- hicle along with orientation lines » Fig. 121 on page 142 .
The area behind the vehicle is monitored by a camera » Fig. 120 .
The system only operates if the ignition is switched on. More information about displaying and operating in the Display » Operating in-
structions for the navigation system .
WARNING■
The system can not replace the driver's attention. Careless or uncontrolled
use of the system can cause accidents and serious injuries.■
Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions.
■
Make sure that the camera lens is not dirty or covered, otherwise the sys-
tem function can be significantly impaired. For information on clean-
ing » page 191 , Camera lens
■
The camera lens distorts and enlarges the field of view of the difference in
eye sight. Objects are displayed deformed.
CAUTION
■ The system can be used only if tailgate is fully closed.■Some items, such as thin columns, chain link fences or lattice may not be repre-
sented adequately in terms of display resolution.■
It is only a two-dimensional display. Therefore, protruding objects or roadway
depressions, for example, may not be recognised due to lack of space depth.
■
In a crash or damage the vehicle's rear camera can possibly deviate from the
correct position. If this is the case, have the sensor checked by a specialist ga-
rage.
CAUTIONWe recommend that you do not use the system in the following situations.■The display is poor, such as when visibility is poor or in the event of a dirty lens.■
The rear of the vehicle is heavily loaded (the area displayed behind the vehicle is
too short).
CAUTION
The objects shown in the display can be closer or even further away than they ap-
pear. This is especially the case in the following situations.■
When driving from a horizontal surface into a slope or a depression.
■
When driving from a slope or a depression onto a horizontal surface.
Orientation lines and monitored area

The navigation system display - Orientation strokes / monitored
area
First read and observe the introductory information and safety warn-
ings
on page 141.
Immovable yellow orientation bars are shown along with the monitored area be-
hind the vehicle on the display.
The distance between the lateral guide bars corresponds to the vehicle width in-
cluding mirrors.
Explanation of graphic The distance behind the vehicle is about 40 cm (clearance limit).The distance behind the vehicle is approximately 100 cm.
AB142Driving
It is necessary to disconnect both cables before charging the battery with high
amperages, known as “ rapid charging”.
The vent plugs of the vehicle battery should not be opened for charging.WARNING“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 228, Jump-starting in vehicles with the START-STOP
system .
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
Replacing
First read and observe the introductory information and safety warn-
ings
on page 207.
The new vehicle battery must have the same capacity, voltage, current and the
same size as the original Battery. Suitable vehicle battery types can be purchased
from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.
Disconnecting and reconnecting
First read and observe the introductory information and safety warn-
ings
on page 207.
On disconnecting and reconnecting the vehicle battery, the following functions
are initially deactivated or are no longer able to operate fault-free.

ber» User manual of the radio

tion systemSetting the clock» page 13Data in the multifunction display are deleted.» page 25
Note
We recommend having the vehicle checked by a specialist garage in order to en-
sure full functionality of all electrical systems.
Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 207.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This manifests itself by the
following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where necessary, large convenience consumers such as seat heaters and rear
window heaters have their power limited or are shut off completely in the event
of an emergency.
CAUTION
■ Despite such intervention by the vehicle electric system management, the vehi-
cle battery may be drained. For example, when the ignition is switched on a long
time with the engine turned off or the side or parking lights are turned on during longer parking.■
Consumers that are supplied via a 12-V power socket can cause the vehicle bat-
tery to discharge when the ignition is switched off.
