Notice: Modifications made to
the engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than those
of the same Tire Performance
Criteria (TPC) can affect the
vehicle’s emission controls and
can cause this light to come on.
Modifications to these systems
could lead to costly repairs not
covered by the vehicle warranty.
This could also result in a failure
to pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications on
page 5-3.
This light comes on during a
malfunction in one of two ways:
Light Flashing: A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
• Reduce vehicle speed.
• Avoid hard accelerations.
• Avoid steep uphill grades.
• If towing a trailer, reduce the
amount of cargo being hauled
as soon as it is possible.
If the light continues to flash, when
it is safe to do so, stop the
vehicle. Find a safe place to park
the vehicle. Turn the key off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and
see your dealer/retailer 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.
An emission system malfunction
might be corrected by:
• Make sure the fuel cap is fully
installed. See Filling the 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 allows fuel
to evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn
the light off.
• If the vehicle has been driven
through a deep puddle of
water, the vehicle’s electrical
system might be wet. The
condition is usually corrected
when the electrical system dries
out. A few driving trips should
turn the light off.
