. Make sure the electrical
system is not wet. The system
could be wet if the vehicle was
driven through a deep puddle of
water. The condition is usually
corrected when the electrical
system dries out. A few driving
trips should turn the light off.
. Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and can
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 9‑48.
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 state/provincial and 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 left of 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.
. The critical emission
control systems have not
been completely diagnosed
by the system. This can
happen if the battery has
recently been replaced or
if the battery has run down.
