Service Engine Soon
The
service engine soon
indicator light illuminates when the
ignition is first turned to the on position to check the bulb and to
indicate whether the vehicle is ready for Inspection/Maintenance
(I/M) testing. Normally, the “service engine soon” light will stay on until the
engine is cranked, then turn itself off if no malfunctions are present.
However, if after 15 seconds the “service engine soon” light blinks eight
times, it means that the vehicle is not ready for I/M testing. See the
Readiness for inspection/maintenance (I/M) testing
in the
Fuel and
Refueling
chapter.
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 the
Fuel and Refueling
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 by your
authorized dealer.
WARNING:
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.

the light remains on, have the system serviced immediately.
Stability Control System Off
Illuminates when AdvanceTrac®/Traction control has been
disabled by the driver.
Transmission Tow/Haul

Refer to the
Transmission
chapter for transmission function
and operation. If the light flashes steadily, have the system
serviced immediately, damage to the transmission could occur.
