Park Assist
With Front and Rear Park Assist, as
the vehicle moves at speeds of less
than 8 km/h (5 mph) the sensors on
the bumpers may detect objects up
to 1.2 m (4 ft) in front and 2.5 m (8 ft)
behind the vehicle within a zone
25 cm (10 in) high off the ground
and below bumper level. These
detection distances may be shorter
during warmer or humid weather.
Blocked sensors will not detect
objects and can also cause false
detections. Keep the sensors clean
of mud, dirt, snow, ice, and slush;
and clean sensors after a car wash
in freezing temperatures.
Warning
The Park Assist system does not
detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at
speeds greater than 8 km/h
