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.

Turning the System On and Off
The UFRPA system can be turned
on and off by pressing the park
assist button in the overhead
console.
The park assist button lights up
when the system is on and turns
off when it has been disabled.
When the System Does Not
Seem to Work Properly
If UFRPA does not turn on due to a
temporary condition, the message
PARK ASSIST OFF displays on the
DIC, and the light on the park assist
button turns off. This can occur
under the following conditions:
.The ultrasonic sensors are not
clean. Keep the sensors free of
mud, dirt, snow, ice, and slush.
For cleaning instructions, see
Exterior Care on page 10‑89.
.The vehicle was washed in cold
weather. This may cause frost
or ice to form in the park assist
sensors. Keep the sensors free
of frost or ice.
.An object was hanging out of the
hatch during the last drive cycle.
Once the attached object is
removed, UFRPA will return to
normal operation.
.The bumper is damaged.
Take the vehicle to your
dealer to repair the system.
.Other conditions may affect
system performance, such as
vibrations from a jackhammer or
the compression of air brakes
on a very large truck.

10-68 Vehicle Care
Replace wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor
System (TPMS) sensors with new
GM original equipment parts.
{WARNING
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling
of the vehicle. Tires can lose air,
and cause loss of control, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
Notice: The wrong wheel
can also cause problems with
bearing life, brake cooling,
speedometer or odometer
calibration, headlamp aim,
bumper height, vehicle ground
clearance, and tire clearance
to the body and chassis.
{WARNING
Rust or dirt on a wheel,
or on the parts to which it is
fastened, can make wheel
nuts become loose after a
time. The wheel could come
off and cause a crash. When
changing a wheel, remove
any rust or dirt from places
where the wheel attaches to
the vehicle. In an emergency,
a cloth or a paper towel can
be used, however, use a
scraper or wire brush to
remove all rust or dirt.
{WARNING
Never use oil or grease on studs
or the threads of the wheel nuts.
The wheel nuts might come loose
and the wheel could fall off,
causing a crash.
{WARNING
Incorrect wheel nuts or improperly
tightened wheel nuts can cause
the wheel to become loose and
even come off. This could lead
to a crash. Be sure to use the
correct wheel nuts. If you have
to replace them, be sure to get
new GM original equipment
wheel nuts.
Notice: Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage.
To avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification.
