indications of the distance between the rear fascia and the
detected obstacle when backing up. Refer to the Warning
Section and Note Section for limitations of this system
and recommendations.
The Rear Park Assist System will remember the last
system state (enabled or disabled) from the last ignition
cycle when the ignition is changed to the RUN/ON

The Rear Park Assist System can be active only when the
shifter is in R (Reverse). If the Rear Park Assist System is
enabled at this shifter position, the system will be active
until the vehicle speed is increased to approximately 11
mph (18 km/h) or above. The system will be active again
if the vehicle speed is decreased to speeds less than
approximately 10 mph (16 km/h).
Rear Park Assist Sensors
The four Rear Park Assist Sensors, located in the rear
fascia, monitor the area behind the vehicle that is within
the sensors' field of view. The monitored area seems oval
in shape.
The sensors can detect obstacles from approximately 11.8
inches (30 cm) up to 59 inches (150 cm) from the rear
fascia in the horizontal direction, depending on the
location and orientation of the obstacle and the type of
obstacle.
