202 Driving and operating
When looking for a parking slot, the
system has to be activated by
pushing the button D for approx.
one second.
The system can only be activated at
a speed up to 30 km/h and the system
searches for a parking slot at a speed
up to 30 km/h.
The maximum allowed parallel
distance between the vehicle and a
row of parking cars is 1.8 metres.
Note
Before using the advanced parking
assist the first time, the vehicle has
to be driven at least for 40 km to
calibrate the system automatically.
Functionality
When the vehicle passes a row of
cars and the system is activated, the
advanced parking assist system
begins looking for a suitable parking
slot. When a suitable slot is detected,
a visual feedback on the Driver
Information Centre and an acoustic
signal are given.
The parking slot suggestion of the
system is accepted when the vehicle
is stopped by the driver within
10 metres after the Stop message is
given. The system calculates the
optimal route into the parking slot.
Then it manoeuvres the driver into the
slot by giving detailed instructions.
