Ultrasonic Rear Parking
Assist (URPA)
If your vehicle is equipped, the Ultrasonic Rear
Parking Assist (URPA) system is designed to help
you park while in REVERSE (R). It operates only at
speeds less than 5 mph (8 km/h). URPA helps
make parking easier and helps you avoid colliding
with objects such as parked vehicles. The URPA
system detects objects that are close to the rear of
the vehicle which are at least 10 inches (25.4 cm)
off the ground and below hood or trunk level. The
system detects objects up to 8 feet (2.5 m) behind
your vehicle. URPA determines how close these
objects are from your bumper within this area.
Ultrasonic sensors on the rear bumper are used
to detect the distance to the object.
{
CAUTION:
The Ultrasonic Rear Park Assist (URPA)
system does not replace driver vision.
URPA does not:
•
Operate above speeds of
5 mph (8 km/h).
•
Detect objects more than 8 feet
(2.5 meters) behind the vehicle. This
distance may be less during warmer or
humid weather.
•
Detect objects that are below the
bumper, underneath the vehicle,
or that are very close to the vehicle.
•
Detect children, pedestrians, bicyclists,
or pets.
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the URPA system,
always check carefully before backing up
by checking behind your vehicle.
