If the light continues to flash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see "If s On Steady" following. If the light is still the Light I flashing, follow the previous steps, and drive the vehicle to your dealer or qualified service center for service. Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 5-5. 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. 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. See Filling Your Tank on page 5-7. 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. 3-37

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.
See
Filling
Your
Tank
on
page
5-7.
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

the cap properly installed
should turn the light
off.
Did you just drive through a deep puddle of water?
Have you recently changed brands of fuel?
If
so,
be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page
5-5.
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.)

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.
If
so,
your electrical system
may be wet. The condition
will usually be corrected when the electrical system
dries out.
A
