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.

This warning light appears on the panel when the
engine oil level falls below the minimum recom -
mended value. Restore the correct engine oil level or
contact your authorized dealer for service.
Yellow Warning Lights
Anti-Lock Brake System (ABS) Warning Light

This light monitors the Anti-Lock Brake System (ABS).
The light will turn on when the ignition is placed in the
ON/RUN or MAR/ON/RUN position and may stay
on for as long as four seconds.

If the ABS light remains on or turns on while driving, then
the Anti-Lock portion of the brake system is not functioning
and service is required. However, the conventional brake
system will continue to operate normally if the brake
warning light is not on.
If the ABS light is on, the brake system should be serviced as
soon as possible to restore the benefits of Anti-Lock Brakes.
If the ABS light does not turn on when the ignition is placed
in the ON/RUN or MAR/ON/RUN position, have the light
inspected by an authorized dealer.
CAUTION!
Continuous driving with the Transmission Temperature
Warning Light illuminated will eventually cause severe
transmission damage or transmission failure.

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.

94 GETTING TO KNOW YOUR INSTRUMENT PANEL
ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating properly,
your vehicle will provide excellent performance and fuel
economy, as well as engine emissions well within current
government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see an
authorized dealer for service as soon as possible.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to access
this information to assist with the diagnosis and service of
your vehicle and emissions system.CAUTION!
• Prolonged driving with the MIL on could cause further damage to the emission control system. It could also
affect fuel economy and driveability. The vehicle must
be serviced before any emissions tests can be
performed.
• If the MIL is flashing while the vehicle is running, severe catalytic converter damage and power loss will
soon occur. Immediate service is required.

For further information, refer to “Cybersecurity” in
“Multimedia”.
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.

96 GETTING TO KNOW YOUR INSTRUMENT PANEL
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle's OBD II system is ready, you must do the following:
1. Cycle the ignition switch to the ON position, but do notcrank or start the engine.
NOTE:
If you crank or start the engine, you will have to start this test
over.
2. As soon as you cycle the ignition switch to the ON posi -
tion, you will see the “Malfunction Indicator Light (MIL)”
symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn OFF the igni -
tion or start the engine. This means that your vehicle's
OBD II system is not ready and you should not proceed
to the I/M station.
• The MIL will not flash at all and will remain fully illumi
-
nated until you place the ignition in the off position or
start the engine. This means that your vehicle's OBD II
system is ready and you can proceed to the I/M station.

If your OBD II system is not ready, you should see an autho -
rized dealer or repair facility. If your vehicle was recently
serviced or had a battery failure or replacement, you may
need to do nothing more than drive your vehicle as you
normally would in order for your OBD II system to update.
A recheck with the above test routine may then indicate that
the system is now ready.
Regardless of whether your vehicle's OBD II system is ready
or not, if the MIL is illuminated during normal vehicle
operation you should have your vehicle serviced before
going to the I/M station. The I/M station can fail your
vehicle because the MIL is on with the engine running.

SAFETY 99
(Continued)
Electronic Stability Control (ESC)
Electronic Stability Control (ESC) enhances directional
control and stability of the vehicle under various driving
conditions. ESC corrects for over/under steering 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 main-
tain 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 appro
-
priate for the steering wheel position.
• Understeer - when the vehicle is turning less than appro -
priate for the steering wheel position.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capabilities
of a BAS-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopardize
the user's safety or the safety of others.
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, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the condi -
tions. 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.4

100 SAFETY
ESC Activation/Malfunction Indicator Light And ESC
OFF Indicator Light The ESC Activation/Malfunction Indicator Light in
the instrument cluster will come on when the igni -
tion switch is turned to the MAR (ON/RUN) posi -
tion for four seconds. If the ESC Activation/Malfunction
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 (km) at speeds greater
than 30 mph (48 km/h), see an authorized dealer as soon as
possible to have the problem diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light (located in
the instrument cluster) starts to flash as soon as the tires lose
traction and the ESC system becomes active. The ESC Activa
-
tion/Malfunction Indicator Light also flashes when TCS is
active. If the ESC Activation/Malfunction Indicator Light
begins to flash during acceleration, 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 momentarily 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 OFF Indicator Light indicates the Electronic
Stability Control (ESC) is partially off.
• Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteristics
of your vehicle, and may negatively affect the perfor -
mance of the ESC system. Changes to the steering
system, suspension, braking system, tire type and size
or wheel size may adversely affect ESC performance.
Improperly inflated and unevenly worn tires may also
degrade ESC performance. Any vehicle modification or
poor vehicle maintenance that reduces the effective -
ness of the ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal injury and
death.
