Object Detection Systems

Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the URPA system, it operates at
speeds less than 8 km/h (5 mph), and assists the driver
with parking and avoiding objects while in R (Reverse).
The sensors on the rear bumper are used to detect the
distance to an object up to 2.5 m (8 ft) behind the
vehicle, and at least 25 cm (10 in) off the ground.
WARNING:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision. It cannot
detect:
Objects that are below the bumper,
underneath the vehicle, or if they are too close
or far from the vehicle
Children, pedestrians, bicyclists, or pets.
If you do not use proper care before and while
backing; vehicle damage, injury, or death could
occur. Even with URPA, always check behind

the vehicle before backing up. While backing, be
sure to look for objects and check the vehicle's
mirrors.
URPA uses three color-coded lights to provide distance
and system information.
How the System Works

moved into R (Reverse). The rear display briefly
illuminates to indicate the system is working.

the rear shelf, below the
