If
the
Light
Is
On
Steady
You may be able
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 dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical
or
electrical
problems that may have developed.
