MALFUNCTION INDICATOR LAMP

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.
If you have recently refueled your
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 three
driving trips.
Malfunction Indicator Lamp
If the indicator remains on past three
driving trips, 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.
