If
the
Lipht
Is
On
Steady
YOU
may
be
ame to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If
so,
reinstall the
fuel
cap, making sure to fully install
the cap. The diagnostic system can determine
if
the fuel
cap has been
left
off or improperly installed.
A
loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A
few driving trips with the cap properly
installed should turn the light
off.
Did you just drive through a deep puddle of water?
If
so,
your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A
few driving trips should turn the light off.
Have you recently changed brands of fuel?
If
so,
be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index).
Poor
fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change
the
fuel brand
you
use. It will require at least
one full tank of the proper fuel to
turn
the light off.
If none of
the
above steps have made the light turn off,
have your retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
