WARNING LIGHTS AND CHIMES
Vehicles equipped with a manual transmission
Vehicles equipped with an automatic transmission
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

bulbs work. If any light remains on after starting the vehicle, refer to the
respective system warning light description for additional information.
Note:Some Warning Lights are reconfigurable telltale (RTT) indicator
lights and will illuminate in the Message Center Display and function the
same as the warning light.
Check engine:TheCheck engine
indicator light illuminates when the
ignition is first turned to the RUN
position to check the bulb. 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.
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 to the RUN
position when the engine is not running, or in a position between RUN
and START, or by applying the parking brake when the ignition is turned
to the RUN 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 servicing authorized dealer.
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 immediately. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
