Rear Vision
Camera (RVC)
If available, the rear vision camera
displays a view of the area behind
the vehicle when the vehicle is
shifted into R (Reverse). The
display will appear on either the
inside rearview mirror or navigation
screen, if equipped.
To clean the camera lens, located
above the license plate, rinse it with
water and wipe it with a soft cloth.
See Rear Vision Camera (RVC) on
page 9‑47.
Ultrasonic Parking Assist
If available, Ultrasonic Rear Parking
Assist (URPA) uses sensors on the
rear bumper to detect objects while
parking the vehicle. URPA comes
on automatically when the shift lever
is moved into R (Reverse) and
operates at speeds less than 8 km/h
(5 mph). URPA uses audio beeps
to provide distance and system
information.
Keep the sensors on the vehicle's
rear bumper clean to ensure proper
operation.
The URPA system can be turned
on and off using the infotainment
system controls. See Vehicle
Personalization on page 5‑30 for
more information.
See Ultrasonic Parking Assist on
page 9‑45 for more information.
Roof Rack System
The roof rack cross rails can be
locked in four positions along the
roof rack side rails. Lift the lever to
release and move the cross rail.
Push the lever down to completely
engage into the side rail holes. Slide
the cross rails back and forth until
the lock pins engage in the holes
and a click is heard.
When the roof rack is not in use,
lock one cross rail at the furthest
forward position and lock the other
cross rail at the furthest rearward
position to reduce wind noise. See
Roof Rack System on page 4‑2.

Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it assists the driver with parking
and avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph),
and the sensors on the rear bumper
detect objects up to 2.5 m (8 ft)
behind the vehicle, and at least
20 cm (8 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 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.
How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is
continuous for 5 seconds.
To be detected, objects must be at
least 20 cm (8 in) off the ground and
below taillamp level. Objects must
also be within 2.5 m (8 ft) from the
rear bumper. The distance objects
can be detected may be less during
warmer or humid weather.

10-56 Vehicle Care
If the TPMS is not functioning
properly, it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
tires or replacing one or more of the
TPMS sensors. The TPMS sensor
matching process should also be
performed after replacing a spare
tire with a road tire containing the
TPMS sensor. The malfunction light
and the DIC message should go
off at the next ignition cycle. The
sensors are matched to the tire/
wheel positions, using a TPMS
relearn tool, in the following order:
driver side front tire, passenger side
front tire, passenger side rear tire,and driver side rear. See your
dealer for service or to purchase a
relearn tool.
There are two minutes to match
the first tire/wheel position, and
five minutes overall to match all
four tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with
the engine off.
3. Use the MENU button to select the Vehicle Information Menu in
the Driver Information Center
(DIC). Use the arrow keys to
scroll to the Tire Pressure
screen.
4. Press the SET/CLR button to begin the sensor matching
process.
A message requesting
acceptance of the process
should display. 5. Press the SET/CLR button again
to confirm the selection.
The horn sounds twice to signal
the receiver is in relearn mode
and the TIRE LEARNING
ACTIVE message displays on
the DIC screen.
6. Start with the driver side front tire.
7. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button
to activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.
8. Proceed to the passenger side front tire, and repeat the
procedure in Step 7.
9. Proceed to the passenger side rear tire, and repeat the
procedure in Step 7.
