The brake pressure drops gradually the more you operate the accelerator pedal. Ifthe vehicle does not start off within 2 seconds, it starts to roll back.
The HHC is active from a 5% slope if the driver's door is closed. HHC is only ever active on slopes when in forward or reverse start off. When driving downhill, it isinactive.

Activation/deactivation
114WARNING■ 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 may not be recognised by the system 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 system 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 continuous tone 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 system to oper-
ate properly.
■ The system function may be limited under adverse weather conditions (heavy
rain, water vapour, very low or high temperatures etc.).■
Additionally installed modules such as bicycle carriers can impair the function of
the parking aid.

Range of sensors
First read and observe the introductory information and safety warn-
ings on page 113.
The parking aid (hereafter referred to solely as system) only works when the igni- tion is switched on.
The system supports the driver via audible signals and the display on the radio or
the factory-installed navigation system when parking and manoeuvring » Radio
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.

These are only the approximate ranges of sensors.
The interval between the acoustic signals becomes shorter as the clearance is re- duced. A continuous tone sounds from a distance of approx. 30 cm - danger area.
From this moment on do not continue reversing!

CAUTION■When washing the car by hand, protect your hands and arms from sharp-edged
metal parts (e.g. when cleaning the underfloor, the inside of the wheel housings
or the wheel trims, etc.) - There is a risk of cuts!■
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 152.
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 152.
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.
