Instruments and Controls

5-23

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.

To 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, 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:

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:

Check that the fuel cap is fully
installed. See

Filling the Tank on

page 9-71

. 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 may require at least one full tank
of the proper fuel to turn the light off.

See

Fuel on page 9-68

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

Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).
