REAR PARK ASSIST SYSTEM— IF EQUIPPED
The Rear Park Assist System provides visual and audible
indications of the distance between the rear fascia and the
detected obstacle when backing up. Refer to the Warning
Section and Note Section for limitations of this system
and recommendations.
The Rear Park Assist System will remember the last
system state (enabled or disabled) from the last ignition
cycle when the ignition is changed to the RUN/ON
position.
The Rear Park Assist System can be active only when the
shifter is in R (Reverse). If the Rear Park Assist System is
enabled at this shifter position, the system will be active
until the vehicle speed is increased to approximately 11
mph (18 km/h) or above. The system will be active again
if the vehicle speed is decreased to speeds less than
approximately 10 mph (16 km/h).
Rear Park Assist Sensors
The four Rear Park Assist Sensors, located in the rear
fascia, monitor the area behind the vehicle that is within
the sensors’ field of view. The monitored area seems oval
in shape.
The sensors can detect obstacles from approximately 11.8
inches (30 cm) up to 59 inches (150 cm) from the rear
fascia in the horizontal direction, depending on the
location and orientation of the obstacle and the type of
obstacle.

Rear Park Assist Warning Display
The Rear Park Assist Warning Display, located in the
headliner near the flipper glass, provides both visual and
audible warnings to indicate the distance between the
rear fascia and the detected obstacle.When the ignition is changed to the RUN/ON position,
the warning display will turn ON all of its LEDs for
about 1 second. Each side of the warning display has 6
yellow and 2 red LEDs. The vehicle is close to the obstacle
when the red LED is ON.
When the obstacle is detected at a distance of about 59
inches (150 cm) from the rear fascia, the outermost LEDs
of the warning display will be ON with increased bright-
ness. Along with the LED, a half second tone will occur.
As the distance of the detected obstacle to the rear fascia
decreases, more LEDs are illuminated. When the warning
display has the first 5 yellow LEDs ON, the warning
display will actuate an intermittent tone for about 10
seconds. The radio will be muted while the tone is
actuated. The intermittent tone will increase in frequency
as each additional LED is lit.

When the detected obstacle is about 11.8 inches (30 cm)
from the rear fascia, the warning display will actuate a
continuous tone for about 10 seconds, and it will turn ON
all 8 LEDs, including both RED LEDs, on the correspond-
ing side of the display. The radio will be muted while the
tone is actuated.
When the obstacle is less than 11.8 inches (30 cm) from
the rear fascia, the warning display will either have all 8
LEDs ON (obstacle detected) or it will have only the
outermost LEDs ON with decreased brightness (obstacle
not detected), depending on the location of the obstacle.
Enable/Disable the Rear Park Assist System
The Rear Park Assist System can be enabled and disabled
with a switch located in the switch bank of the instru-
ment panel.When the switch is pressed to disable the system, the
instrument cluster will display thePARK ASSIST DIS-
ABLEDmessage. Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in Section 4 of this manual. When the
shifter is changed to R (Reverse) and the system is

disabled, the instrument cluster will actuate a single
chime, once per ignition cycle, and it will display the
message.
The Rear Park Assist Switch LED will be ON when the
Rear Park Assist System is disabled or defective. The
Rear Park Assist Switch LED will be OFF when the
system is enabled.
Service the Rear Park Assist System
When the Rear Park Assist System is defective, the
instrument cluster will actuate a single chime, once per
ignition cycle, and it will display theSERVICE PARK
ASSIST SYSTEMmessage. Refer to “Electronic Vehicle
Information Center (EVIC)” in Section 4 of this manual.
Cleaning the Rear Park Assist System
Clean the Rear Park Assist Sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. Do
not scratch or poke the sensors. Otherwise, you could
damage the sensors.

CAUTION!
•The Rear Park Assist System is only a parking aid
and it is unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will not
be detected when they are in close proximity.
•The vehicle must be driven slowly when using the
Rear Park Assist System to be able to stop in time
when the obstacle is detected. It is recommended
that the driver looks over his/her shoulder when
using the Rear Park Assist System.
WARNING!
•Drivers must be careful when backing up even
when using the Rear Park Assist System. Always
check carefully behind your vehicle, look behind
you, and be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind spots before
backing up. You are responsible for safety and must
continue to pay attention to your surroundings.
Failure to do so can result in serious injury or death.
•Before using the Rear Park Assist System, it is
strongly recommended that the ball mount and
hitch ball assembly is disconnected from the
vehicle when the vehicle is not used for towing.
Failure to do so can result in injury or damage to
vehicles or obstacles because the hitch ball will be
much closer to the obstacle than the rear fascia
when the warning display turns the red LEDs ON.
Also, the sensors could detect the ball mount and
hitch ball assembly, depending on its size and
shape, giving a false indication that an obstacle is
behind the vehicle.
142 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:Clean all four Rear Park Assist Sensors regularly,
taking care not to scratch or damage them. The sensors
must not be covered with ice, snow, slush, mud, dirt or
debris. Failure to do so can result in the system not
working properly. The system might not detect an ob-
stacle behind the fascia or it could provide a false
indication that an obstacle is behind the fascia.
Assure objects are not within 11.8 inches (30 cm) from the
rear fascia while driving the vehicle. Failure to do so can
result in the system misinterpreting a close object as a
sensor problem, causing theSERVICE PARK ASSIST
SYSTEMmessage to be displayed in the instrument
cluster.Ultrasonic noise from airbrakes of nearby trucks, air
powered jackhammers and air powered shop tools, to
name a few, will cause the Rear Park Assist System to be
disabled until the ultrasonic noise is no longer present.

•Do not drive too fast for road conditions, especially
when roads are wet or slushy. A wedge of water can
build up between the tire tread and the road. This
hydroplaning action can cause loss of traction, braking
ability, and control.
•After going through deep water or a car wash, brakes
may become wet, resulting in decreased performance
and unpredictable braking action. Dry the brakes by
gentle, intermittent pedal action while driving at very
slow speeds.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.If for some reason, the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and does not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short period of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and does not in any
way damage the steering system.
246 STARTING AND OPERATING

•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out-of-tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
•The use of fuel additives which are now being sold as
octane enhancers are not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives are not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
