The warning/indicator lights will illuminate in the instrument
panel together with a dedicated message and/or acoustic signal
when applicable. These indications are indicative and precau-
tionary and as such must not be considered as exhaustive and/
or alternative to the information contained in the Owner’s
Manual, which you are advised to read carefully in all cases.
Always refer to the information in this chapter in the event of a
failure indication. All active telltales will display first if appli -
cable. The system check menu may appear different based upon
equipment options and current vehicle status. Some telltales are
optional and may not appear.

Red Warning Lights

86 GETTING TO KNOW YOUR INSTRUMENT PANEL

Operation of the Brake Warning Light can be checked by turning
the ignition switch from the OFF position to the ON/RUN posi-
tion. The light should illuminate for approximately two seconds.
The light should then turn off unless the parking brake is applied
or a brake fault is detected. If the light does not illuminate, have
the light inspected by an authorized dealer.

The light also will turn on when the parking brake is applied
with the ignition switch in the ON/RUN position.
NOTE:
This light shows only that the parking brake is applied. It
does not show the degree of brake application.
Battery Charge Warning Light
This warning light will illuminate when the battery
is not charging properly. If it stays on while the
engine is running, there may be a malfunction with
the charging system. Contact an authorized dealer as soon as
possible.
This indicates a possible problem with the electrical system
or a related component. Door Open Warning Light
This indicator will illuminate when one or more
door(s) are not fully closed.
NOTE:
If the vehicle is moving and a door is opened, there will also
be a single chime.
Electronic Throttle Control (ETC) Warning Light This warning light will illuminate to inform of a
problem with the Electronic Throttle Control (ETC)
system. If a problem is detected while the vehicle is
running, the light will either stay on or flash depending on
the nature of the problem. Cycle the ignition when the
vehicle is safely and completely stopped and the transmis -
sion is placed in the PARK (P) position. The light should turn
off. If the light remains on with the vehicle running, your
vehicle will usually be drivable; however, see an authorized
dealer for service as soon as possible.

GETTING TO KNOW YOUR INSTRUMENT PANEL 87
If the light continues to flash when the vehicle is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is placed in the ON/RUN or
MAR/ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting, have the
system checked by an authorized dealer.
Engine Coolant Temperature Warning Light This warning light warns of an overheated engine
condition. If the engine coolant temperature is too
high, this indicator will illuminate and a single
chime will sound. If the temperature reaches the upper limit,
a continuous chime will sound for four minutes or until the
engine is able to cool, whichever comes first.
If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift the
transmission into NEUTRAL (N) and idle the vehicle. If the
temperature reading does not return to normal, turn the
engine off immediately and call for service.
Refer to “If Your Engine Overheats” in “In Case Of Emer -
gency” for further information. Oil Pressure Warning Light
This warning light will illuminate to indicate low
engine oil pressure. If the light turns on while
driving, stop the vehicle, shut off the engine as soon
as possible, and contact an authorized dealer. A chime will
sound 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.
Transmission Temperature Warning Light — If Equipped
This warning light will illuminate to warn of a high
transmission fluid temperature. This may occur with
strenuous usage such as trailer towing. If this light
turns on, stop the vehicle and run the engine at idle or
slightly faster, with the transmission in PARK (P) or
NEUTRAL (N), until the light turns off. Once the light turns
off, you may continue to drive normally.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illuminated
you could cause the fluid to boil over, come in contact
with hot engine or exhaust components and cause a fire.

Low Fuel Warning LightWhen the fuel level reaches approximately 2–3 gal
(9–11 L) this light will turn on, and remain on until
fuel is added.
Generic Warning Light The Generic Warning Light will illuminate if any of
the following conditions occur: Engine Oil Pressure
Sensor Failure, External Light Failure, Parking
Sensor Failure, Fuel Cut-Off Fail/Intervention, Generic
Failure on Trailer, or Air Bag telltale recovery.
The telltale will blink in case of an Air Bag Warning Light
Failure. Contact an authorized dealer immediately for
service.
Tire Pressure Monitoring System (TPMS) Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is lower
than the recommended value and/or that slow pres -
sure loss is occurring. In these cases, optimal tire duration
and fuel consumption may not be guaranteed. Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.
As an added safety feature, your vehicle has been equipped
with a Tire Pressure Monitoring System (TPMS) that illumi
-
nates a low tire pressure telltale when one or more of your
tires is significantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them to the
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.

Engine Check/Malfunction Indicator Warning Light (MIL)
The Engine Check/Malfunction Indicator Light
(MIL) is a part of an Onboard Diagnostic System
called OBD II that monitors engine and automatic
transmission control systems. This warning light will illu -
minate when the ignition is in the ON/RUN position before
engine start. After placing the ignition to the ON/RUN
position, if there is a problem with the Sentry Key System,
the Vehicle Security Light will turn on. This condition will
result in the engine being shut off after two seconds. If the
bulb does not come on when turning the ignition switch
from OFF to ON/RUN, have the condition checked
promptly.

NOTE:
This warning light will illuminate when the vehicle security
alarm system has detected an attempt to break into the
vehicle.
Certain conditions, such as a loose or missing gas cap, poor
quality fuel, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through
several typical driving styles. In most situations, the vehicle
will drive normally and will not require towing. When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced by an authorized dealer as soon as
possible if this occurs.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you drive
slowly or park over flammable substances such as dry
plants, wood, cardboard, etc. This could result in death
or serious injury to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction Indicator Light
(MIL) on could cause damage to the vehicle control
system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.3

Electronic Stability Control (ESC) Warning Light — If
Equipped
The Electronic Stability Control (ESC) Indicator Light in
the instrument cluster will come on when the ignition is
placed in the ON/RUN or MAR/ON/RUN position, and
when ESC is activated. It should go out with the engine running. If
the “ESC Indicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the vehicle has
been driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see your authorized dealer as soon as possible
to have the problem diagnosed and corrected.

• The “ESC OFF Indicator Light” and the “ESC Indicator Light” come on momentarily each time the ignition is
placed in the ON/RUN or MAR/ON/RUN position.

• Each time the ignition is turned to ON/RUN or MAR/ON/ RUN, 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.
• This light will come on when the vehicle is in an ESC event. Electronic Stability Control (ESC) OFF Warning Light —
If Equipped
This warning light indicates the Electronic Stability
Control (ESC) is off.

Each time the ignition is turned to ON/RUN or ACC/ON/RUN,
the ESC system will be on, even if it was turned off previously.

Green Indicator Lights
Turn Signal Indicator Lights When the left or right turn signal is activated, the
turn signal indicator will flash independently and
the corresponding exterior turn signal lamps will
flash. Turn signals can be activated when the multifunction
lever is moved down (left) or up (right).
NOTE:
• A continuous chime will sound if the vehicle is driven more than 1 mile (1.6 km) with either turn signal on.
• Check for an inoperative outside light bulb if either indicator flashes at a rapid rate.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle's emissions control system. Failure
to pass could prevent vehicle registration.For states that require an Inspection and Mainte -
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not on
when the engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a depleted battery or a battery
replacement. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
WARNING!
• ONLY an authorized service technician should connect equipment to the OBD II connection port in order to
read the VIN, diagnose, or service your vehicle.
• If unauthorized equipment is connected to the OBD II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information stored in your vehicle systems, including personal
information.
