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 are
reconfigurable telltale (RTT)
indicator lights and will illuminate in
the message center. These lights
function the same as the other
warning lights.
Service engine soon:The
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 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.
Powertrain malfunction/reduced
power (RTT) (if equipped):
Displays when the vehicle has
defaulted to a “limp-home”
operation. Report the fault to a dealer at the earliest opportunity.
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, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level 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.

chapter to activate/deactivate the Belt-Minder
chime feature.
Charging system (RTT):
Illuminates when the battery is not
charging properly. If it stays on

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.
Anti-theft system:Flashes when
the SecuriLock
Passive Anti-theft
System has been activated.
