Parking aid
Introduction
This chapter contains information on the following subjects:
Function
112
Activation/deactivation
113WARNING■ 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 reversing the vehicle
or carrying out similar manoeuvres. Pay particular attention to small children
and animals as they are not recognised by the parking aid sensors.■
Before reversing, you should make sure that there are no small obstacles,
such as rocks, thin posts, trailer drawbars etc. behind your vehicle. Such ob-
stacles may not be recognised by the parking aid sensors.
■
Under certain circumstances, surfaces of certain objects and types of cloth-
ing cannot reflect the system signals. Thus, these objects or people who wear
such clothing are not recognised by the System sensors.
■
External sound sources can have a detrimental effect on the system. Under
adverse conditions, this may cause objects or people to not be recognised by the system.
CAUTION
■ 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. Have the fault
rectified by a specialist garage.■
The sensors must be kept clean (free of ice, etc.) to enable the parking aid to
operate properly.
■
Under adverse weather conditions (heavy rain, water vapour, very low or high
temperatures etc.) system function may be limited.
■
Additionally installed modules such as bicycle carriers can impair the function of
the parking aid.
FunctionFig. 100
Parking aid: Range of sensors
First read and observe the introductory information and safety warn- ings on page 112.
The parking aid (referred to below solely as system) only works when the ignition
is switched on.
The system supports the driver via audible signals, via the display on the radio or
via the factory-installed navigation system when parking and manoeuvring » Ra-
dio user guide, Navigation system user guide.
The system uses ultrasound waves to calculate the distance between the bumper
and an obstacle. The ultrasonic 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
A
» Fig. 100 ). The interval between the warning signals becomes shorter as
the clearance is reduced.
A continuous tone sounds from a distance of approx. 30 cm (area
B
) - danger
area. You should not reverse any further after this signal sounds!
On vehicles with a factory-fitted towing device, the border of the danger area starts (continuous tone) 5 cm further away from the vehicle. The length of the ve-
hicle can be increased with an installed detachable towing device.
112Driving

CAUTION■When washing the car by hand, protect your hands and arms from sharp-edged
metal parts (e.g. when cleaning the undertray, exhaust system, the inside of the
wheel housings or the wheel trims etc.) - there is a risk of cutting yourself.■
Only apply slight pressure when cleaning the vehicle's paintwork.
Automatic car wash systems
First read and observe the introductory information and safety warn-
ings
on page 149.
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/tilting
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.
WARNINGFold in the exterior mirrors to prevent damage before washing the vehicle in
an automatic car wash system.
Washing with a high-pressure cleaner
First read and observe the introductory information and safety warn-
ings
on page 149.
When washing the vehicle with a high-pressure cleaner, the instructions for use
of the equipment must be observed. This applies in particular to the pressure
used and to the spraying distance .
Maintain a sufficiently large distance to the parking aid sensors and soft materials
such as rubber hoses or insulation material.
WARNINGNever use circular spray nozzles or dirt cutters!
CAUTION
■ If washing the vehicle in the winter using a hose or high-pressure cleaner, en-
sure 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 periods
while a minimum distance of 10 cm must be observed.
■
The temperature of the water used for cleaning must not exceed 60 °C – risk of
damaging the vehicle.

Regular and proper care help to retain the efficiency and value of your vehicle. It
may also be one of the requirements for the acceptance of warranty claims relat- ing to corrosion damage and paint defects on the bodywork.
150General Maintenance

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 188, Jump-starting in vehicles with the START-STOP
system .
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
Disconnecting or reconnecting
First read and observe the introductory information and safety warn-ings
on page 168.
The following functions are initially deactivated or are no longer able to operate
faultlessly after the vehicle battery has been disconnected and reconnected.

ber» User manual of the radio
or » user manual of the naviga-
tion systemSetting the clock» page 12Data in the multifunction display are deleted.» page 13
Note
We recommend having the vehicle checked by a specialist garage in order to en-
sure full functionality of all electrical systems.
Replacing
First read and observe the introductory information and safety warn-
ings
on page 168.
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. 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.
Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 168.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This may be noticed from
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.
Note
Driving comfort is not impaired by consumers being deactivated. The driver is of-
ten not aware of it having taken place.
