This indicator should light when the
ignition switch is ON (II), and go out
after the engine starts. If it comes on
at any other time, it indicates one of
the engine's emissions control
systems may have a problem. Even
though you may feel no difference in
your car's performance, it can
reduce your fuel economy and cause
your car to put out excessive
emissions. Continued operation may
cause serious damage.

Taking Care of the Unexpected
If you have recently refueled your
L L A A M M P P
car, the cause of this indicator
coming on could be a loose or
missing fuel fill cap. Check the cap
and tighten it until it clicks several
times. Replace the fuel fill cap if it is
missing. Tightening the cap will not
make the indicator turn off
immediately; it takes at least one
driving trip.
If the indicator remains on, or the
fuel cap was not loose or missing,
have the car checked by the dealer
as soon as possible. Drive
moderately until the dealer has
inspected the problem. Avoid full-
throttle acceleration and driving at
high speed.
You should also have the dealer
inspect your car if this indicator
comes on repeatedly, even though it
may turn off as you continue driving.
If you keep driving with the
malf unction indicator lamp on, you can
damage your car's emissions controls
and engine. Those repairs may not be
covered by your car's warranties.
