Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the Ultrasonic Rear Parking Assist
(URPA) system, it operates at speeds less than 5 mph
(8 km/h), 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 8 feet (2.5 m) behind the vehicle, and
at least 10 inches (25.4 cm) off the ground.
{CAUTION:
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.
CAUTION: (Continued)
CAUTION: (Continued)
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.
The display is located near
the passenger side rear
window and can be
seen by looking over your
right shoulder.
URPA uses three color-coded lights to provide distance
and system information.

How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). The rear display briey
illuminates to indicate the system is working.
URPA operates only at speeds less than 5 mph (8 km/h).
If the vehicle is above this speed, the red light on the rear
display will ash.
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below tailgate level.
Objects must also be within 8 feet (2.5 m) from the rear
bumper. This distance may be less during warmer or
humid weather.
A single beep will sound the rst time an object is
detected between 40 inches (1 m) and 8 feet (2.5 m)
away. Beeping will occur continuously when the vehicle
is at 23 inches (0.6 m) or closer to an object.The following describes what will occur with the URPA
display as the vehicle gets closer to a detected object:
Description English Metric
amber light 8 ft 2.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights
and continuous beeping
for ve seconds23 in 0.6 m
amber/amber/red lights
ashing and continuous
beeping for ve seconds1 ft 0.3 m
The system can be
disabled by pressing the
rear park aid disable button
located next to the radio.
The indicator light will come on and PARK ASSIST OFF
displays on the Driver Information Center (DIC) to
indicate that URPA is off, seeDIC Warnings and
Messages on page 3-66for information about clearing
the message.
2-62

Notice:If you use URPA while the tailgate is
lowered, it may not detect an object behind your
vehicle, and you might back into the object and
damage your vehicle. Always verify the tailgate is
closed when using URPA or turn off URPA when
driving with the tailgate lowered.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on
the rear URPA display when the shift lever is moved into
R (Reverse). This occurs under the following conditions:
The driver disables the system.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-118.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the tailgate during the
last drive cycle, the red light may illuminate in
the rear display. Once the attached object is
removed, URPA will return to normal operation.
A tow bar is attached to the vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer 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.
If the system is still disabled, after driving forward at
least 15 mph (25 km/h), take the vehicle to your
dealer/retailer.

Rear Vision Camera (RVC)
This vehicle may have a Rear Vision Camera system.
Read this entire section before using it.
{CAUTION:
The Rear Vision Camera (RVC) system does not
replace driver vision. RVC does not:
Detect objects that are outside the camera’s
eld of view, below the bumper, or underneath
the vehicle.
Detect children, pedestrians, bicyclists, or pets.
Do not back the vehicle by only looking at the rear
vision camera screen, or use the screen during
longer, higher speed backing maneuvers or where
there could be cross-traffic. Your judged distances
using the screen will differ from actual distances.
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 RVC system,
always check carefully before backing up by
checking behind and around the vehicle.
Vehicles Without Navigation System

When the System Does Not Seem To
Work Properly
The rear vision camera system might not work properly
or display a clear image if:
The RVC is turned off. See “Turning the Rear
Camera System On or Off” earlier in this section.
It is dark.
The sun or the beam of headlights is shining
directly into the camera lens.
Ice, snow, mud, or anything else builds up on the
camera lens. Clean the lens, rinse it with water,
and wipe it with a soft cloth.
The back of the vehicle is in an accident, the
position and mounting angle of the camera can
change or the camera can be affected. Be sure to
have the camera and its position and mounting
angle checked at your dealer/retailer.
There are extreme temperature changes.The rear vision camera system display in the rearview
mirror may turn off or not appear as expected due to
one of the following conditions. If this occurs the
left indicator light on the mirror will ash.
A slow ash may indicate a loss of video signal, or
no video signal present during the reverse cycle.
A fast ash may indicate that the display has been
on for the maximum allowable time during a
reverse cycle, or the display has reached an Over
Temperature limit.
The fast ash conditions are used to protect the
video device from high temperature conditions.
Once conditions return to normal the device
will reset and the green indicator will stop ashing.
