If the light continues to flash,
when it is safe to do so, stop the
vehicle. Find a safe place to park.
Turn the vehicle off, wait at least
10 seconds, and restart the engine.
If the light is still flashing, follow the
previous steps and see your dealer
for service as soon as possible.
Light On Steady: An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emissions system malfunction:
. Check that the fuel cap is fully
installed. See Filling the Tank on
page 9‑55. The diagnostic
system can determine if the
fuel cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn
the light off.
. Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand used.
It will require at least one full tank of
the proper fuel to turn the light off.
See Recommended Fuel on
page 9‑52.
If none of the above have made
the light turn off, your dealer can
check the vehicle. The dealer has
the proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
Emissions Inspection and
Maintenance Programs
Some local governments may have
programs to inspect the on-vehicle
emission control equipment.
For the inspection, the emission
system test equipment is
connected to the vehicle’s Data
Link Connector (DLC).
The DLC is under the instrument
panel to the next to the steering
wheel. See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
. The malfunction indicator lamp
is on with the engine running,
or if the light does not come on
when the ignition is turned to
ON/RUN while the engine is off.
