Caution (Continued)
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 10-3.
This light can come on during a
malfunction in one of two ways:
Light Flashing (Gasoline Engine
Only): A misfire condition has been
detected and is present. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
To prevent more serious damage to
the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If the light continues to flash, find a
safe place to stop and park the
vehicle. 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 (All Engines): An
emission control system malfunction
has been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emission control system
malfunction:
For gasoline engines, check that
the gas cap is fully installed. See
Filling the Tank on page 9-61.
The diagnostic system can
determine if the gas cap has
Instruments and Controls
been left off or improperly
installed. A loose or missing gas
cap allows gasoline to evaporate
into the atmosphere. A few
driving trips with the cap
properly installed should turn the
light off.
For all engines, 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 may require at least one full tank
of the proper fuel to turn the light off.
