WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Note:Some warning lights will display in the message center as words
and function the same as the warning light.
Note:Depending on which options your vehicle has, some indicators
may not be present in your vehicle.
Service engine soon:The service
engine soon indicator light
illuminates when the ignition is first
turned to the on position to check
the bulb and to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. Normally, the service engine soon
light will stay on until the engine is cranked, then turn itself off if no
malfunctions are present. However, if after 15 seconds the service engine
soon light blinks eight times, it means that the vehicle is not ready for
I/M testing. See theReadiness for Inspection/Maintenance (I/M)
testingin theMaintenance and Specificationschapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could

damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and contact your authorized dealer
as soon as possible.
If the light remains on while driving, the temperature of the engine may
be too high; refer toEngine coolantin theMaintenance and
Specificationschapter.
WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.
Powertrain malfunction
indicator:Illuminates when a
powertrain or an AWD fault has
been detected. Contact your
authorized dealer as soon as
possible.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
when the engine is not running, or in a position between on and start, or
by applying the parking brake when the ignition is turned to the on
position. If the brake system warning light does not illuminate at this
time, contact your authorized dealer as soon as possible. Illumination
after releasing the parking brake indicates low brake fluid level. Contact
your authorized dealer as soon as possible.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Contact your authorized dealer as soon as possible. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.

ABS light stays illuminated or
continues to flash, a malfunction has
been detected. Contact your
authorized dealer as soon as
possible. Normal braking is still functional unless the brake warning light
also is illuminated.
Airbag readiness:If this light fails
to illuminate when the ignition is
turned to on, continues to flash or
remains on, contact your authorized
dealer as soon as possible. A chime will sound if there is a malfunction in
the indicator light.
Safety belt:Reminds you to fasten
your safety belt. A Belt-Minder

chime will also sound to remind you
to fasten your safety belt. Refer to
theSeating and Safety Restraints
chapter to activate/deactivate the Belt-Minder
chime feature.
Charging system:Illuminates 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
your authorized dealer as soon as
possible. This indicates a problem
with the electrical system or a related component.
Engine oil pressure:Illuminates
when the oil pressure falls below the
normal range. Check the oil level
and add oil if needed. Refer to
Engine oilin theMaintenance and Specificationschapter.
Engine coolant temperature:
Illuminates when the engine coolant
temperature is high. Stop the
vehicle as soon as possible, switch
off the engine and let cool. Refer to
