Malfunction Indicator Lamp
If this indicator comes on
while driving, it means one
of the engine's emissions control
systems may have a problem. Even
though you may feel no difference in
your vehicle's performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damage.
If you have recently refueled your
vehicle, the indicator could come on
because of a loose or missing fuel fill
cap. Tighten the cap until it clicks at
least three times. Tightening the cap
will not turn the indicator turn off
immediately; it takes at least three
days of normal driving.

If the indicator remains on past
three days of normal driving, or
comes on repeatedly, even
though it may turn off as you
continue driving, have the
vehicle checked by the dealer as
soon as possible.
NOTICE: If you keep driving with the
Malf unction Indicator Lamp on, you
can damage your vehicle's emission
controls and the engine. Those repairs
may not be covered by your vehicle's
warranties.
Readiness Code
Your vehicle has certain ''readiness
codes'' that are part of the on-board
diagnostics for the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
Malfunction Indicator Lamp
If your vehicle battery has been
disconnected or gone dead, these
codes are erased. It takes at least
three days of driving under various
conditions to set the codes again.
To check if they are set, turn the
ignition to ON (II), without starting
the engine. The Malfunction
Indicator Lamp will come on for 20
seconds. If it then goes off, the
readiness codes are set. If it blinks 5
times, the readiness codes are not
set. If possible, do not take your
vehicle for a state emissions test
until the readiness codes are set.
