of view
Audible signal(dashboard loudspeaker)
•Sound pulses emitted at a rate that increases as the
distance decreases.
•Emits continuous tone at 12 in (30 cm).
•Adjustable volume level. (Refer to “Electronic Ve-
hicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information).

•Icon appears on display.
•Message is displayed on the Electronic Vehicle
Information Center (EVIC) (where provided).
While audible signals are emitted, the audio system is not
muted.
The audible signal is turned off immediately if the
distance increases. The tone cycle remains constant if the
distance measured by the inner sensors is constant. If this
condition occurs for the external sensors, the signal is
turned 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 in-
strument panel warning icon and message displayed on
the Electronic Vehicle Information Center (EVIC) display.
The warning icon is illuminated and a message
is displayed on the EVIC display (if equipped).
Refer to#Electronic Vehicle Information Center
(EVIC)#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 EVIC shall indicate that the
Rear Park Assist system is unavailable, 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
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 temporarily de-
tected or not detected at all. Obstacles located
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 before
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 warning display turns on the single
flashing arc and 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.

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. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.
28. Electronic Vehicle Information Center (EVIC)
The EVIC features a driver-interactive display that is
located in the instrument cluster. For further information,
refer to “Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel.”

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and vehicle
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system, Brake Limited
Differential (BLD), functions similar to a limited slip
differential and controls the wheel spin across a driven
axle. If one wheel on a driven axle is spinning faster than
the other, the system will apply the brake of the spinning
wheel. This will allow more torque to be applied to the
wheel that is not spinning. This feature remains active
even if TCS and ESC are in the Partial Off mode. Refer to
“Electronic Stability Control (ESC)” in this section for
further information.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the oversteering or understeering condi-
tion. Vehicle power may also be reduced to help the
vehicle maintain the desired path. ESC uses sensors in
the vehicle to determine the vehicle path intended by the
driver and compares it to the actual path of the vehicle.
When the actual path does not match the intended path,
ESC applies the brake of the appropriate wheel to assist
in counteracting the oversteer or understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.
NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
•Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
•It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and
to maintain the proper pressure.
264 STARTING AND OPERATING

•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the level
to trigger illumination of the “Tire Pressure Monitor-
ing Telltale Light.”
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Premium TPM System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
The TPMS consists of the following components:
•Receiver module
•Four Tire Pressure Monitoring Sensors
•Various Tire Pressure Monitoring System messages,
which display in the Electronic Vehicle Information
Center (EVIC)
•Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime will
sound when tire pressure is low in one or more of the
four active road tires. In addition, the Electronic Vehicle
Information Center (EVIC) will display a graphic show-
ing the pressure values of each tire with the low tire
pressure tire highlighted in a different color.
