Page 170 of 263

168Driving and operatingThe maximum allowed parallel
distance between the vehicle and a
row of parked cars is 1.8 metres.
Functionality
When the vehicle passes a row of
cars and the system is activated, the
advanced parking assist system
begins searching for a suitable
parking slot. When a suitable slot is
detected, visual feedback in the
Driver Information Centre and an
acoustic signal are given.
If the driver does not stop the vehicle
within 10 metres after a parking slot is
proposed, the system starts to search for another suitable parking slot.
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.The instructions in the display show:
● A hint when driving faster than 30 km/h.
● The demand to stop the vehicle, when a parking slot is detected.
● The direction of driving during the
parking manoeuvre.
● The steering wheel position during parking.
● For some of the instructions a progress bar is shown.
