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.

If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.

This indicator may also come on
along with the ‘‘D’’ indicator.

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.

To check if they are set, turn the
ignition switch 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
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
for more information (see page

).

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. You will also see a ‘‘CHECK
FUEL CAP’’ message on the
odometer display. 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.
