8. External Light Failure Indicator — If Equipped
The External Light Failure Indicator will come on when a
failure to one of the following lights is detected:•Side Marker Lights
• Brake Lights
• Direction Indicators
• Backup Lights
• Parking Lights
• Headlights
• Tail Lights
• D.R.L.
• Clearance Lights
• License Plate Lights
The failure relating to these lights could be: one or more

electrical connection. 9. Door Ajar Indicator
This indicator will illuminate when one or more door(s)
are not fully closed.
10. Glow Plug Light — If Equipped
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. The Glow Plug
light will flash during in cold weather for up to 10 sec-
onds. An externally powered electric engine block heater
is available as optional equipment or from your autho-
rizeddealer.
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.

of the vehicle by applying the brake of the appropriate
wheel to assist in counteracting the over/under steer
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 match
the 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!
The Electronic Stability Control System (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
all accidents, including those resulting from exces-
sive speed in turns, driving on very slippery surfaces,
or hydroplaning. ESC also cannot prevent accidents
resulting from loss of vehicle control due to inappro-
priate driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ESC equipped vehicle must
never be exploited in a reckless or dangerous manner
which could jeopardize the user ’s safety or the safety
of others.

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 off.Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. Note that TSC cannot stop
all trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue weight
recommendations. Refer to “Trailer Towing” in this sec-
tion for further information. When TSC is functioning,
the “ESC Activation/Malfunction Indicator Light” will
flash, the engine power may be reduced and you may
feel the brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is disabled
when the ESC system is in the “Partial Off” mode.
