Object Detection
Systems

Ultrasonic Parking Assist

For vehicles with the Ultrasonic
Front and Rear Parking Assist
(UFRPA) system, it assists the
driver with parking and avoiding
objects. UFRPA operates at
speeds less than 8 km/h (5 mph).
The sensors on the front and rear
bumper detect objects up to
1.2 m (4 ft) in front of the vehicle,
2.5 m (8 ft) behind the vehicle, and
at least 25.4 cm (10 in) off the
ground.
WARNING
The Ultrasonic Front and Rear
Parking Assist (UFRPA) 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 moving forward and while
backing; vehicle damage, injury,
or death could occur. Even with
UFRPA, always check in front of
the vehicle before moving forward
and behind the vehicle before
backing up. While moving forward
and backing, be sure to look for
objects and check the vehicle
mirrors.
Driving and Operating
How the System Works
UFRPA comes on automatically
when the shift lever is moved into
R (Reverse). The front and rear
sensors are automatically turned on.
After the vehicle is shifted out of
R (Reverse), the rear sensors are
turned off and the front sensors
stay on until the vehicle is above a
speed of 8 km/h (5 mph). The front
sensors may also be turned on by
pressing the park assist button in
the overhead console without
shifting into R (Reverse) while the
vehicle is traveling at a low speed.
See Turning the System On and
Off later in this section.
When the vehicle is in N (Neutral),
the system may be active. If the
vehicle is in a car wash, the sensors
may detect objects in the car wash.
See Turning the System On and
Off later in this section to turn the
system off.
