If the 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 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 have recently refueled your

vehicle, the indicator coming on

could be due to a loose or missing

fuel fill cap. Tighten the cap until it

clicks at least once. Tightening the

cap will not turn the indicator off

immediately; it can take several days

of normal driving.

The indicator may also come on with

the ‘‘D’’ indicator.

You will also see a ‘‘CHECK

EMISSION SYSTEM’’ message on

the multi-information display (see

page ).

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 the battery in your vehicle 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 an emissions

test until the readiness codes are set.

Refer to for

more information (see page ).
