Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the URPA system, it operates at
speeds less than 5mph (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 on
the rear shelf, below the
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 trunk 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 23 inches (0.5 m) and 8 feet
(2.6 m) away. Beeping will occur for a short time
when the vehicle is closer than 1 foot (0.3 m) from
the 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 23 in 0.6 m
amber/amber/red lights
ashing and beep for
ve seconds1 ft 0.3 m
The system can be disabled through the Driver
Information Center (DIC). See “Park Assist” under
DIC Operation and Displays on page 3-49for more
information.
2-39

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, seeWashing Your
Vehicle on page 5-96.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk 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.

{CAUTION:
SBZA is only a lane changing aid and does not
replace driver vision. SBZA does not detect:
Vehicles outside the side blind zones which
may be rapidly approaching.
Pedestrians, bicyclists, or animals.
Failure to use proper care when changing lanes
may result in damage to the vehicle, injury, or
death. Always check the outside and rearview
mirrors, glance over your shoulder, and use the
turn signal before changing lanes.
When the system detects a vehicle in the side blind
zone, amber SBZA displays will light up in the side
mirrors. This indicates that it may be unsafe to change
lanes. Before making a lane change, always check
the SBZA display, check the outside and rearview
mirrors, look over your shoulder for vehicles and
hazards, and use the turn signal.
SBZA Detection Zones
The SBZA sensor covers a zone of approximately one
lane over from both sides of the vehicle, 11 ft. or 3.5 m.
This zone starts at each side mirror and goes back
approximately 16 ft. (5.0 m). The height of the zone is
approximately between 1.5 ft. (0.5 m) and 6 ft. (2.0 m) off
the ground.
The SBZA detection zones do not change if the vehicle
is towing a trailer. So be extra careful when changing
lanes while towing a trailer.
2-41

How the System Works
When the vehicle is started, both outside mirror displays
will briey come on to indicate that the system is
operating. While driving forward, the left or right side
mirror SBZA display will light up if a vehicle is detected
in that blind zone. If you activate a turn signal and a
vehicle has been detected on the same side, the SBZA
display will ash to give you extra warning not to
change lanes.
SBZA displays do not come on while the vehicle is
approaching or passing other vehicles. At speeds greater
then 20 mph (32 km/h), SBZA displays may come on
when a vehicle you have passed remains in or drops
back into the detection zone.SBZA can be disabled through the Driver Information
Center (DIC). SeeDriver Information Center (DIC)
on page 3-49for more information. If the SBZA
is disabled by the driver, the SBZA mirror displays will
not light up during normal driving.
When the System Does Not Seem To Work
Properly
Occasional missed alerts can occur under normal
circumstances and will increase in wet conditions.
The system does not need to be serviced due to an
occasional missed alert. The number of missed
alerts will increase with increased rainfall or road spray.
If the SBZA displays do not light up when the system
is on and vehicles are in the blind zone, the system may
need service. Take the vehicle to your dealer/retailer.
SBZA is designed to ignore stationary objects; however,
the system may occasionally light up due to guard
rails, signs, trees, shrubs, and other stationary objects.
This is normal system operation, the vehicle does
not need service. Left Side Mirror DisplayRight Side Mirror

SBZA does not operate when the left or right corners of
the rear bumper are covered with mud, dirt, snow, ice,
slush, or in heavy rainstorms. For cleaning instructions,
seeWashing Your Vehicle on page 5-96. If the DIC still
displays the SIDE BLIND ZONE SYS. UNAVAILABLE
message after cleaning the bumper, see your
dealer/retailer.
The SBZA displays may remain on if a trailer is attached
to the vehicle, or a bicycle or object is extending out
to either side of the vehicle.
When SBZA is disabled for any reason other than the
driver turning it off, the driver will not be able to turn SBZA
back on using the DIC. The SIDE BLIND ZONE ALERT
ON option will not be selectable if the conditions for
normal system operation are not met. Until normal
operating conditions for SBZA are met, you should not
rely upon SBZA while driving.SBZA Error Messages
The following messages may appear in the DIC:
SIDE BLIND ZONE ALERT SYSTEM OFF:This
message indicates that the driver has turned the
system off.
SIDE BLIND ZONE SYS. UNAVAILABLE:This
message indicates that the SBZA system is disabled
because the sensor is blocked and cannot detect
vehicles in the blind zone. The sensor may be blocked
by mud, dirt, snow, ice, slush, or even heavy rainstorms.
This message may also activate during heavy rain or
due to road spray. The vehicle does not need service.
For cleaning, seeWashing Your Vehicle on page 5-96.
SERVICE SIDE BLIND ZONE ALERT SYSTEM:If this
message appears, both SBZA displays will remain on
indicating there is a problem with the SBZA system.
If these displays remain on after continued driving,
the system needs service. Take the vehicle to your
dealer/retailer.

Lane Departure Warning (LDW)
The vehicle may have a Lane Departure Warning (LDW)
system. Read this entire section before using the
system.
{CAUTION:
The Lane Departure Warning (LDW) system does
not steer the vehicle and is only an aid to help you
stay in your driving lane. The LDW system may not:
Provide you with enough time to avoid a lane
change collision.
Be loud enough for you to hear the warning
beeps.
Work properly under bad weather conditions or
if the windshield is not kept clean.
Detect lane markings and will not detect road
edges.
Warn you that your vehicle is crossing a lane
marking if the system does not detect the lane
marking.
CAUTION: (Continued)
CAUTION: (Continued)
LDW will indicate the system is working whenever
it detects either the left or right lane marking. So if
you depart on the side of the lane that LDW is not
detecting, LDW will not warn you.
If you do not carefully maintain your vehicle
position within the lane, vehicle damage, injury, or
death could occur. Even with LDW, always keep
your attention on the road and maintain proper
vehicle position within the lane. Always keep the
windshield clean and do not use LDW in bad
weather conditions.
When the vehicle crosses a detected lane marking, the
LDW symbol will ash and you will hear three beeps.
LDW will not warn you if the turn signal is on or if
you make a sharp maneuver. Before making a lane
change, check the vehicle’s mirrors, glance over your
shoulder for vehicles and hazards, and start the
turn signal before changing lanes.
2-44

How the System Works
LDW uses a camera located between the inside
rearview mirror and the windshield to detect the lane
markings.
@(Lane Departure Warning):To turn LDW on and
off, press the LDW control, located by the exterior
headlamp control. An indicator on the control will light
to indicate that LDW is on.
When the vehicle is
started, the LDW symbol,
located in the instrument
panel cluster, will briey
come on to indicate that
the light is operational.LDW only operates at speeds of 35 mph (56 km) or
greater. If LDW is turned on when traveling at these
speeds, the LDW symbol will appear green if the system
detects a left or right lane marking. This symbol will
change to amber and ash and three beeps will sound if
you cross a detected lane marking without using the
turn signal.
If the LDW symbol does not appear, LDW is not
currently operating and will not warn you.
To change the volume of the warning chime, see Chime
Volume underDIC Vehicle Customization on page 3-66
for more information.
2-45

When the System Does Not Seem To Work
Properly
The LDW symbol will not appear when the system is
having difficulty seeing the lines on the road or if the view
of the camera on the windshield is blocked with mud, dirt,
snow, ice, or slush, if the windshield is damaged, or when
weather limits visibility, such as while driving in fog, rain,
or snow conditions. This is normal operation, the vehicle
does not need service. For cleaning instructions, see
Washing Your Vehicle on page 5-96.
LDW warnings may occasionally occur due to tar marks,
shadows, cracks in the road, or other road imperfections.
This is normal system operation, the vehicle does not
need service.
LDW Error Message

message may appear in the DIC to indicate that LDW is
not working properly. If this message remains on after
continued driving, the system needs service. Take your
vehicle to your dealer/retailer.
LANE DEPARTURE SYSTEM UNAVAILABLE:This
message may appear in the DIC if LDW does not
activate due to a temporary condition.
