WARNING LIGHTS AND CHIMES
Standard instrument cluster
Optional instrument cluster
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.
Service engine soon:TheService
engine soonindicator 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 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 (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.
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.

of the following conditions has
occurred:
•The engine coolant temperature
is high.
•The engine oil pressure is low.
•The fuel gauge is at or near empty.
Low tire warning (if equipped
with the Tire Pressure
Monitoring System):Illuminates
when your tire pressure is low. If
the light remains on at start up or
while driving, the tire pressure should be checked. Refer toInspecting
and Inflating Your Tiresin theTires, Wheels and Loadingchapter.
When the ignition is first turned to ON, the light will illuminate for 3
seconds to ensure the bulb is working. If the light does not turn ON,
have the system inspected by your servicing dealership. For more
information on this system, refer toUnderstanding Your Tire Pressure
Monitoring Systemin theTires, Wheels and Loadingchapter.
Electronic throttle control:
Illuminates when the engine has
defaulted to a ’limp-home’ operation.
Report the fault to a dealer at the
earliest opportunity.
