Dodge 2008 JS Avenger Sedan - Manual (Page 180)

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
(Refer to “Tire Inflation Pressures” under “Tires — Gen-
eral Information” and to “Tire Pressure Monitor System
(TPMS)” in Section 5 of this manual for more informa-
tion).
25. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors emissions, engine, and
automatic transaxle control systems. The light
will illuminate when the key is in the ON/RUN position
before engine start. If the bulb does not come on when
turning the key from LOCK/OFF to ON/RUN, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
If the Malfunction Indicator Light flashes when the
engine is running, serious conditions may exist that
