ment Panel” for further information. When the shift lever is
moved to REVERSE and the system is disabled, the EVIC
will display the “PARKSENSE OFF” message for as long as
the vehicle is in REVERSE.
NOTE:The ParkSense® system will automatically dis-
able when the system detects that a trailer with trailer
brakes has been connected to the Integrated Trailer Brake
Module. The EVIC will display “PARKSENSE OFF”
message for as long as the vehicle is in reverse.
The ParkSense® switch LED will be ON when
ParkSense® is disabled or defective. The ParkSense®
switch LED will be OFF when the system is enabled.
If the ParkSense switch is pressed, and the system is
disabled or requires service, the ParkSense switch LED
will blink momentarily, and then the LED will be ON.
Service The ParkSense® Rear Park Assist System
During vehicle start up, when the ParkSense® Rear Park
Assist System has detected a faulted condition, the
instrument cluster will actuate a single chime, once per
ignition cycle, and it will display the PARKSENSE
UNAVAILABLE WIPE REAR SENSORS or the
PARKSENSE UNAVAILABLE SERVICE REQUIRED 
message. Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” for
further information. When the shift lever is moved to
REVERSE and the system has detected a faulted condi-
tion, the EVIC will display the PARKSENSE UNAVAIL-
ABLE WIPE REAR SENSORS or thePARKSENSE UN-
AVAILABLE SERVICE REQUIRED message for as long
as the vehicle is in REVERSE. Under this condition,
ParkSense® will not operate.
If PARKSENSE UNAVAILABLE WIPE REAR SENSORS

Electronic Stability Control (ESC) — If Equipped
The ESC system enhances directional control and stabil-
ity of the vehicle under various driving conditions. ESC
corrects for oversteering or understeering of the vehicle
by applying the brake of the appropriate wheel to assist
in counteracting the oversteer or understeer condition.
Engine 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 matchthe intended path, ESC applies the brake of the appro-
priate 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.WARNING!
Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. ESC also cannot prevent accidents resulting

STARTING AND OPERATING 523

The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
NOTE:
•The “ESC Activation/Malfunction Indicator Light”
and the “ESC OFF Indicator Light” come on momen-
tarily each time the ignition switch is turned ON.
• Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.
•
The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop when ESC becomes inactive following the maneuver that
caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is partially
off.
Trailer Sway Control (TSC) — If Equipped
The TSC system uses sensors in the vehicle to recognize
an excessively swaying trailer and will take the appro-
priate actions to attempt to stop the sway. The system
may reduce engine power and apply the brake of the
appropriate wheel(s) to counteract the sway of the trailer.
TSC will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired to activate. Note that TSC cannot stop all trailers
from swaying. Always use caution when towing a trailer
and follow the trailer tongue weight recommendations.
