WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive 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
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.

Check fuel cap:Illuminates when
the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Check
engine warning light to come on,
refer toFuel filler capin the
Maintenance and Specificationchapter.
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.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.
Air bag readiness:If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also sound when a malfunction in the
supplemental restraint system has been detected.

System warnings
System warnings alert you to possible problems or malfunctions in your
vehicle’s operating systems.
In the event of a multiple warning situation, the message center will
cycle the display to show all warnings by displaying each one for 4
seconds.
The message center will display the last selected feature if there are no
more warning messages. This allows you to use the full functionality of
the message center after you acknowledge the warning by pressing the
RESET control and clearing the warning message.
Warning messages that have been reset are divided into three categories:
•They will reappear on the display ten minutes from the reset.
•They will not reappear until an ignition OFF-ON cycle has been
completed.
•Warning returns upon another event.
This acts as a reminder that these warning conditions still exist within
the vehicle.
