To check if they are set, turn the
ignition 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 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
for more information (see page
).
If your vehicle battery has been
disconnected or gone dead, these
codes are erased. If takes at least
three days of normal driving to set
the codes again.
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 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 multi-information display.
Tighten the cap until it clicks at least
once (see page
). Tightening the
cap will not turn the indicator off
immediately; it takes at least three
days of normal driving.
If this indicator comes on
while driving, or if you see
a ‘‘CHECK EMISSION
SYSTEM’’ message on the multi-
information display, 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 go off as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.
