WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive 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
bulbs work. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Service engine soon:TheService
engine soonindicator light
illuminates when the ignition is first
turned on to check the bulb and to
indicate whether the vehicle is ready for Inspection/Maintenance (I/M)
testing. Normally, theService engine soonlight will stay on until the
engine is cranked, then turn itself off if no malfunctions are present.
However, if after 15 seconds theService engine soonlight blinks eight
times, it means that the vehicle is not ready for I/M testing. See the
Readiness for Inspection/Maintenance (I/M) testingin the
Maintenance 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 have your vehicle serviced
immediately by your authorized dealer.

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.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned on 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 on. If the brake
system warning light does not illuminate at this time, seek service
immediately from your authorized dealer. Illumination after releasing the
parking brake indicates low brake fluid level or a brake system
malfunction and the brake system should be inspected immediately by
your authorized dealer.
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.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. 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 on, continues to flash or
remains on, have the system
serviced immediately by your authorized dealer. A chime will also sound
when a malfunction in the supplemental restraint system has been
detected.

is low. If the light remains on at
start up or while driving, the tire
pressure should be checked. Refer
toInflating your tiresin theTires, Wheels and Loadingchapter. When

to ensure the bulb is working. If the light does not turn on or begins to
flash, have the system inspected by your authorized dealer. For more
