Malfunction Indicator Lamp
If you have recently refueled your
vehicle, the cause of this indicator
coming on could be a loose or
missing fuel fill cap. Check the cap
or replace it. Tightening the cap will
not make the indicator turn off
immediately; it takes several days of
normal driving.
If the indicator remains on or the
fuel cap was not loose or missing,
have the vehicle checked by the
dealer as soon as possible.
If you keep driving with the
Malf unction Indicator Lamp on, you
can damage your vehicle's emissions
controls and engine. Those repairs may
not be covered by your vehicle's
warranties. This indicator may also
come on with the ''D'' indicator.

Readiness Codes

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.
If your vehicle's 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 switch to the ON (II)
position, 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 five 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. Refer to
State
