Driving and operating199Activation
When searching for a parking slot, the
system is ready to operate by
pressing button (.
The system can only be activated at
a speed up to 18 mph and the system searches for a parking slot at a speed up to 18 mph.
The 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 looking for a suitable parking
slot. When a suitable slot is detected, a visual feedback and acoustic
signals are given in the Driver
Information Centre.
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.
