Parking Aids 225
When a suitable space is found, the touch screen displays a message and
a chime sounds. Slow down and stop at approximately position (A), then
follow the instructions on the touch screen.
Note: You must observe that the selected space remains clear of
obstructions at all times in the maneuver.
Note: Vehicles with overhanging loads (e.g. a bus or a truck), street
furniture and other items may not be detected by active park assist. You
must ensure the selected space is suitable for parking.
Note: The vehicle should be driven as parallel to other vehicles as
possible while passing a parking space.
Note: The system always offers the last detected parking space (i.e. if
the vehicle detects multiple spaces while you are driving, it offers the
last one).
Note: If driven above approximately 20 mph (35 km/h), the touch
screen shows a message to alert the driver to reduce vehicle speed.
Automatic Steering into Parking Space
Note: If vehicle speed exceeds 7 mph (12 km/h), the system turns off
and you need to take full control of the vehicle.
Note: If a maneuver is interrupted before completion, the system turns
off. The steering wheel position will not indicate the actual position of
the steering and you have to full take control of the vehicle. I some
instances a message may appear that would allow you to resume the
maneuver.
