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.
Check engine:TheCheck engine
indicator light illuminates when the
ignition is first turned to the ON
position to check the bulb. Solid

started indicates the On Board Diagnostics System (OBD-II) has
detected a malfunction. Refer toOn board diagnostics (OBD-II)in the

floor coverings or other vehicle components, possibly causing a fire.
