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, have the
respective system inspected immediately.

indicator light illuminates when the
ignition is first turned to the ON
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 to On board
diagnostics (OBD-II) in the Maintenance 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.

light is functional, it will

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
