WARNING LIGHTS AND CHIMES
Low fuel
Illuminates as an early reminder of a
low fuel condition indicated on the
fuel gauge. The light comes on when
there is approximately 1/16th of a
tank indicated on the fuel gauge
(refer toFuel Gaugein this chapter for more information). The ignition
must be in the ON position for this lamp to illuminate. The lamp will also
illuminate for several seconds after the ignition is turned to the ON
position regardless of the fuel level.
Service engine soon
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This
system is commonly known as the
On Board Diagnostics System (OBD
II). The OBD II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD II system also assists the
service technician in properly servicing your vehicle.
TheService Engine Soonindicator light illuminates when the ignition is
first turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine's emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.

Safety belt
Momentarily illuminates when the
ignition is turned to the ON position
to remind you to fasten your safety
belts. For more information, refer to
theSeating and safety restraints
chapter.
Brake system warning
Momentarily illuminates when the
ignition is turned to the ON
position, the engine is off and the
parking brake is engaged. If the
brake warning lamp does not
illuminate at this time, seek service immediately. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately.
Anti-lock brake system (ABS)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If the light
remains on, continues to flash or
fails to illuminate, have the system
serviced immediately. With the ABS light on, the anti-lock brake system
is disabled and normal braking is still effective unless the brake warning
light also remains illuminated with parking brake released.
Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. If one or both of the
indicators stay on continuously or
flash faster, check for a burned-out
turn signal bulb. Refer toExterior bulbsin theMaintenance and care
chapter.

described below:
²First, at least 10 minutes of driving on an expressway or highway.
²Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
