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.
Parking aid

This chapter contains information on the following subjects:

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!
