If the indicator remains on past three

inspect your vehicle if this indicator
comes on repeatedly, even though it
may turn of f as you continue driving.
This indicator comes on when you
turn the ignition switch ON (II), and
goes of f af ter the engine starts. If it
comes on at any other time, it
indicates one of the engine’s
emissions control systems may have
a problem. Even though you may
f eel no dif f erence in your vehicle’s
perf ormance, it can reduce your f uel
economy and cause your vehicle to
put out excessive emissions.
Continued operation may cause
serious damage. If you have recently ref ueled your
vehicle, the cause of this indicator
coming on could be a loose or
missing f uel f ill cap. Check the cap
and tighten it until it clicks several
times. Replace the f uel f ill cap if it is
missing. Tightening the cap will not
make the indicator turn of f
immediately; it takes at least three
driving trips.
This indicator may also come on
along with the ‘‘D ’’ indicator.
