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.

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.
Check fuel cap (if equipped):
Illuminates when the fuel cap may
not be properly installed. Continued
driving with this light on may cause
the Service engine soon light to
come on, refer toFuel filler capin theMaintenance and
Specificationschapter.
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 dealership. Illumination after releasing the parking brake
indicates low brake fluid level and the brake system should be inspected
immediately by your servicing dealership.
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 dealer immediately.
