Rear Park Assist Sensors
The four Rear Park Assist sensors, located in the rear
fascia/bumper, monitor the area behind the vehicle that
is within the sensors’ field of view. The sensors can detect
obstacles, in the horizontal direction, from approximately
12 in (30 cm) up to 55 in (140 cm) from the center of the
rear fascia/bumper and up to 24 in (60 cm) from the
corners of the rear fascia/bumper, depending on the
location, type and orientation of the obstacle.
If several obstacles are detected, the Rear Park Assist
system indicates the nearest obstacle.
The minimum height of a detectable obstacle corre-
sponds to the maximum height of an obstacle that would
clear the underside of the car during the parking
maneuver.
Rear Park Assist Alerts
If an obstacle is behind the vehicle when REVERSE gear
is engaged, an audible alert is activated.
The tones emitted by the loudspeaker inform the driver
that the vehicle is approaching an obstacle. The pauses
between the tones are directly proportional to the dis-
tance from the obstacle. Pulses emitted in quick succes-
sion indicate the presence of a very close obstacle. A
continuous tone indicates that the obstacle is less than
12 in (30 cm) away.

Audible And Visual Signals Supplied By The Rear Park Assist System.
SIGNALMEANING INDICATION
Obstacle Distance An obstacle is present within the
sensors’ field of view Audible signal
(dashboard loudspeaker)
• Sound pulses emitted at a rate that in-
creases as the distance decreases.
• Emits continuous tone at 12 in (30 cm)
• Adjustable volume level. (Refer to
“Menu Functions” for further information).
Failure Sensor or System failures Visual Signal
(instrument panel)
• Icon appears on display.
• Message is displayed on multifunction
display (where provided).
While audible signals are emitted, the audio system is not
muted.
The audible signal is cut out immediately if the distance
increases. The tone cycle remains constant if the distance measured by the inner sensors is constant. If this condi-
tion occurs for the external sensors, the signal is cut off
after 3 seconds (stopping warnings during maneuvers
parallel to walls).

Failure Indications
A malfunction of the Rear Park Assist sensors or system
is indicated, during REVERSE gear engagement, by the
instrument panel warning icon.The warning icon is illuminated and a message
is displayed on the multifunction display (if
equipped). Refer to “Instrument Cluster De-
scriptions” in “Understanding Your Instrument
Panel” for further information.
The sensors and wiring are tested continuously when the
ignition is in the ON/RUN position. Failures are indi-
cated immediately if they occur when the system is ON.
Even if the system is able to identify that a specific sensor
is in failure condition, the instrument cluster display
shall indicate that the Rear Park Assist system is unavail-
able, without reference to the sensor in failure condition.
If even a single sensor fails, the entire system must be
disabled. The system is turned off automatically.
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. In
washing stations, clean sensors quickly keeping the va-
por jet/high pressure washing nozzles at least 4 in
(10 cm) from the sensors. Do not scratch or poke the
sensors. Otherwise, you could damage the sensors.
Park Assist System Usage Precautions
NOTE:
•Ensure that the outer surface and the underside of the
rear bumper is clean and clear of snow, ice, mud, dirt
or other obstruction to keep the Rear Park Assist
system operating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of Rear Park Assist.
•Clean the Rear Park Assist sensors regularly, taking
care not to scratch or damage them. The sensors must
3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 115

not be covered with ice, snow, slush, mud, dirt or
debris. Failure to do so can result in the system not
working properly. The Rear Park Assist system might
not detect an obstacle behind the fascia/bumper, or it
could provide a false indication that an obstacle is
behind the fascia/bumper.
•Objects such as bicycle carriers, etc., must not be
placed within 12 in (30 cm) from the rear fascia/
bumper while driving the vehicle. Failure to do so can
result in the system misinterpreting a close object as a
sensor problem, causing a failure indication to be
displayed in the instrument cluster.
CAUTION!
•Rear Park Assist is only a parking aid and it is
unable to recognize every obstacle, including
small obstacles. Parking curbs might be temporar-
ily detected or not detected at all. Obstacles lo-
cated above or below the sensors will not be
detected when they are in close proximity.
•The vehicle must be driven slowly when using
Rear Park Assist in order to be able to stop in time
when an obstacle is detected. It is recommended
that the driver looks over his/her shoulder when
using Rear Park Assist.

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 be-
fore backing up. You are responsible for safety and
must continue to pay attention to your surround-
ings. Failure to do so can result in serious injury or
death.(Continued)
WARNING! (Continued)
•Before using the Rear Park Assist system, it is
strongly recommended that the ball mount and
hitch ball assembly is disconnected from the ve-
hicle 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 loudspeaker sounds the continuous
tone. 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.

INSTRUMENT CLUSTER DESCRIPTIONS
1. Glow Plug Light — If EquippedThe Glow Plug light will flash during engine oil
viscosity sensor measurement in cold weather.
During this measurement (up to 10 seconds), the starter
will be disabled. If the measured oil viscosity is OK, the
light will turn off and the engine will be allowed to crank.
If the measured oil viscosity is too high, engine cranking
will be disabled and the light will blink repeatedly until
the oil temperature is raised, preferably by an externally-
powered electric engine block heater (available from
your authorized dealer).
The message Plug In Engine Heater, will be displayed
in the instrument cluster when the ambient temperature
is below 5°F (-15°C) at the time the engine is shut off as
a reminder to avoid possible crank delays at the next cold
start. 2. Rear Defrost Button

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
16. Automatic Gearbox Failure This light will illuminate when there is an
automatic transmission fault. 17. Oil Pressure Warning Light
This light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns
on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
18. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBDII, that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF/LOCK
to ON/RUN, have the condition checked promptly.

Cold Weather Operation
To prevent possible engine damage while starting at low
temperatures, this vehicle will inhibit engine cranking
when the ambient temperature is less than –22° F (–30° C)
and the oil temperature sensor reading indicates an
engine block heater has not been used. An externally-
powered electric engine block heater is available as
optional equipment or from your authorized dealer.
The messageplug in engine heater will be displayed in the
instrument cluster when the ambient temperature is below
5° F (–15° C) at the time the engine is shut off as a reminder
to avoid possible crank delays at the next cold start.
CAUTION!
Use of the recommended SAE 5W-30 oil and adher-
ing to the prescribed oil change intervals is important
to prevent engine damage and ensure satisfactory
starting in cold conditions.
If Engine Fails To Start
WARNING!
Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
CAUTION!
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned
fuel could enter the catalytic converter and once
the engine has started, ignite and damage the
converter and vehicle.
