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, continued operation
may cause serious damage.
If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have your vehicle
checked by your 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.

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 can take several
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 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. Refer to
