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.
