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 coming on
could be due to a loose or missing
fuel fill cap. You will also see a ‘‘ CHECK FUEL CAP ’’message on
the information display. 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. 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 malfunction
indicator lamp on, you can damage
your vehicle's emissions controls and
engine. Those repairs may not be
covered by your vehicle's warranties.
If your vehicle has an automatic
transmission, the malfunction
indicator lamp 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 the battery in your vehicle has been
disconnected or gone dead, these
codes may be 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 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 Emissions Testing for more
information (see page 319).

If something electrical in your
vehicle stops working, check for a
blown fuse first. Determine from the
chart on pages 301 and 302, or the
diagram on the fuse box lid, which
fuse or fuses control that device.
Check those fuses first, but check all
the fuses before deciding that a
blown fuse is the cause. Replace any
blown fuses, and check if the deviceworks.
1. Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are off.
