Park Assist System Usage
Precautions
NOTE:
• Jackhammers, large trucks, and
other vibrations could affect the
performance of Park Assist.
• Objects such as bicycle carriers, trailer
hitches, etc., must not be placed
within 30 cm (12 in) from the rear
bumper while driving the vehicle.
Failure to do so can result in the
system misinterpreting a close object
as a sensor problem, causing the
service Park Assist message to be
displayed in the instrument cluster.
CAUTION!
•
Park Assist is only a parking aid and it
is unable to recognise every obstacle,
including small obstacles. Parking
curbs might only be temporarily
detected or not detected at all.
Obstacles located above or below the
sensors will not be detected when
they are in close proximity.
•
The vehicle must be driven slowly
when using Park Assist in order to be
able to stop in time when an obstacle
is detected. When backing up, it is
recommended that the driver looks
over his/her shoulder when using
Park Assist.
WARNING!
Drivers must be careful when backing
up even when using the Park Assist
system. Always check carefully behind
your vehicle, look behind you, and be
sure to check for pedestrians, animals,
other vehicles, obstructions, and
blind spots before backing up. You
are responsible for safety and must
continue to pay attention to your
surroundings. Failure to do so can
result in serious injury or death.
Park Assist Volume
The volume of the acoustic signal
emitted by the front and rear parking
sensors is set to the medium level.
Three different level of volume can
be selected the submenu "Safety &
Driving Assistant" of the "Settings"
page on MIA.
Low level is useful in certain conditions
when the parking sensor acoustic
signal keeps coming on although there
is no actual collision hazard. This may
typically occur when driving in a queue
or when the vehicle is overtaken by
motorcycles or other vehicles on one or
both sides in a queue of traffic. When
