WARNING LIGHTS AND MESSAGES

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 precautionary
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
applicable. 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
Seat Belt Reminder Warning Light
When the ignition is first placed in the
ON/RUN or MAR/ON/RUN position, if
the driver’s seat belt is unbuckled, a
chime will sound and the light will turn
on. When driving, if the driver or front passenger
seat belt remains unbuckled, the Seat Belt
Reminder Light will flash or remain on
continuously and a chime will sound
Ú page 164.
Air Bag Warning Light
This light will turn on for four to eight
seconds as a bulb check when the
ignition is placed in the ON/RUN or
MAR/ON/RUN position. If the light is
either not on during startup, stays on, or turns
on while driving, have the system inspected at
an authorized dealer as soon as possible. This
light will illuminate with a single chime when a
fault with the Air Bag Warning Light has been
detected, it will stay on until the fault is cleared.
If the light comes on intermittently or remains
on while driving, have an authorized dealer
service the vehicle immediately.
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 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
transmission 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.
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.
Transmission Fault Warning Light
This light will illuminate (together with
a message in the instrument cluster
display and a buzzer) to indicate a
transmission fault. Contact an
authorized dealer if the message remains after
restarting the engine.
Engine Temperature Warning Light
This 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 light turns on while driving, safely pull over
and stop the vehicle. If the Air Conditioning (A/C)
system is on, turn it off. Also, shift the
transmission into NEUTRAL and idle the vehicle.
If the temperature reading does not return to
normal, turn the engine off immediately and call
for service
Ú
page 206.

Brake Warning Light
This warning light monitors various
brake functions, including brake fluid
level and parking brake application. If
the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a
problem with the Anti-Lock Brake System
reservoir.
If the light remains on when the parking brake
has been disengaged, and the fluid level is at
the full mark on the master cylinder reservoir, it
indicates a possible brake hydraulic system
malfunction or that a problem with the Brake
Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability
Control (ESC) system. In this case, the light will
remain on until the condition has been
corrected. If the problem is related to the brake
booster, the ABS pump will run when applying
the brake, and a brake pedal pulsation may be
felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in either
half of the dual brake system is indicated by the

Electronic Stability Control (ESC) Warning
Light
The ESC Indicator Light in the
instrument cluster will come on when
the ignition is placed in the ON/RUN
or MAR (ACC/ON/RUN) position, and
when ESC is activated. It should turn off 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 an authorized
dealer as soon as possible to have the problem
diagnosed and corrected.
The ESC OFF Indicator Light and the ESC Indi
-
cator Light come on momentarily each time
the ignition is placed in the ON/RUN or MAR
(ACC/ON/RUN) position.
Each time the ignition is turned to ON/RUN or
MAR (ACC/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
This light indicates the ESC is off.
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.
Engine Check/Malfunction Indicator
Warning Light
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 illuminate when the ignition is
in the ON/RUN position before engine start. If
the bulb does not come on when turning the
ignition switch from OFF to ON/RUN, have the
condition checked promptly.
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.
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 operation 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. Using aftermarket tire
sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire
sealant it is recommended that you take your
vehicle to an authorized dealer to have your
sensor function checked.

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 Maintenance (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.
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. 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. Switch the ignition to the ON position, but
do not crank 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 position, 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 ignition 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 illuminated 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 authorized 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.

Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
AVV/START or MAR/ACC/ON/RUN position. If
the ignition switch is in the STOP/OFF/LOCK
position the air bag system is not on and the air
bags will not inflate. The ORC contains a backup power supply
system that may deploy the air bag system even
if the battery loses power or it becomes
disconnected prior to deployment.

The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch
is in the MAR/ACC/ON/RUN position. After the
self-check, the Air Bag Warning Light will turn off.
If the ORC detects a malfunction in any part of the
system, it turns on the Air Bag Warning Light,
either momentarily or continuously. A single
chime will sound to alert you if the light comes on
again after initial startup.

The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While the
air bag system is designed to be maintenance
free, if any of the following occurs, have an
authorized dealer service the air bag system
immediately.
The Air Bag Warning Light does not come on
during the four to eight seconds when the
ignition switch is first in the MAR/ACC/ON/
RUN position.
The Air Bag Warning Light remains on after
the four to eight-second interval.
The Air Bag Warning Light comes on intermit
-
tently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be
disabled. In this condition the air bags may not
be ready to inflate for your protection. Have an
authorized dealer service the air bag system
immediately.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it
comes on as you drive, have an authorized
dealer service the air bag system
immediately.
