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 if they are 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. The display is located in the
headliner.
URPA uses three color-coded lights
to provide distance and system
information.
How the System Works
URPA comes on automatically
and the display briefly illuminates
to indicate the system is working
when the shift lever is moved into
R (Reverse).

8-48 Driving and Operating
If the vehicle is traveling faster then
8 km/h (5 mph) in reverse, the red
light on the rear display flashes.
Objects must be at least 20 cm (8 in)
off the ground, below liftgate level,
and within 2.5 m (8 ft) from the rear
bumper to be detected. The
distance may be less during warmer
or humid weather.
A single beep sounds the first time
an object is detected between
0.6 m (23 in) and 2.5 m (8 ft) away.
Beeping occurs continuously when
the vehicle is 0.6 m (23 in) or closer
to an object.The following describes how the URPA display lights appear as the vehicle
gets closer to a detected object:
Description Metric Englishamber light 2.5 m 8 ft
amber/amber lights 1.0 m 40 in
amber/amber/red lights and continuous beeping for five seconds 0.6 m 23 in
amber/amber/red lights flashing and continuous beeping for five seconds 0.3 m 1 ft

Tow Bar
When the tow bar setting is used,
an area of 16 cm (6 in) around the
hitch is not detected by the system.
When the System Does Not
Seem to Work Properly
If the URPA system does not
activate due to a temporary
condition, the message Park Assist
Off displays on the DIC and a red
light is shown on the rear URPA
display when the shift lever is
moved into R (Reverse). This can
occur under the following
conditions:
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice and slush. For cleaning
instructions, see Exterior Care
on page 9‑85.
.A trailer was attached to the
vehicle, or an object was
hanging out of the liftgate during
the last drive cycle, a red light
may come on in the rear display.
Once the attached object is
removed, URPA will return to
normal operation.
.A tow bar is attached to the
vehicle and the tow bar setting is
not being used, or an odd
shaped tow bar is attached to
the vehicle and the tow bar
setting is being used.
.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 25 km/h
(15 mph), take the vehicle to your
dealer/retailer.

8-50 Driving and Operating
Rear Vision
Camera (RVC)
The vehicle may have a Rear Vision
Camera (RVC) system. Read this
entire section before using it.
The RVC can assist the driver when
backing up by displaying a view of
the area behind the vehicle.
{WARNING
The Rear Vision Camera (RVC)
system does not replace driver
vision. RVC does not:
.Detect objects that are
outside the camera's field of
view, below the bumper,
or underneath the vehicle.
.Detect children, pedestrians,
bicyclists, or pets.(Continued)
WARNING (Continued)
Do not back the vehicle by only
looking at the RVC 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.

different from the actual distance. The following illustration shows the
field of view that the camera
provides.

Driving and Operating 8-53
A. View displayed by the camera.
B. Corner of the rear bumper.
When the System Does Not
Seem To Work Properly
The RVC system may 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.
The RVC 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 flash.
.A slow flash may indicate a loss
of video signal, or no video
signal present during the reverse
cycle.
.A fast flash 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 flash 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 flashing.
During any of these fault conditions,
the display will be blank and the
indicator will continue to flash as
long as the vehicle is in R (Reverse)
or until the conditions return to
normal.
Pressing and holding
zwhen the

9-12 Vehicle Care
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A“Change Engine Oil
Soon” message comes on.
See Engine Oil Messages
on
page 4‑31. Change the oil as soon as possible within the next 1 000 km
(600 miles). It is possible that,
if driving under the best conditions,
the oil life system might not indicate
that an oil change is necessary for
over a year. However, the engine oil
and filter must be changed at least
once a year and at this time the
system must be reset. Your dealer/
retailer has trained service people
who will perform this work using
genuine parts and reset the system.
It is also important to check the oil
regularly and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Turn the ignition to ON/RUN with
the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
If the vehicle has Driver Information
Center (DIC) buttons:
1. Turn the ignition to ON/RUN, with the engine off.
2. Press the DIC menu button until “Remaining Oil Life” displays.
3. Press and hold the set/clear button until “100%”is displayed.
4. Turn the key to LOCK/OFF.
The system is reset when the
“Change Engine Oil Soon” message
goes off.
