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 or
misfiring. 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.
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 and local governments
have or might begin programs
to inspect the emission control
equipment on the vehicle. Failure to
pass this inspection could prevent
getting a vehicle registration.
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 vehicle may not pass this
inspection if the malfunction
indicator lamp is on while the
vehicle is in ON/RUN, or if the
vehicle is placed in Service Only

Instruments and Controls
Mode and the malfunction
indicator lamp does not
come on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.
The vehicle may not pass
this inspection if the OBD II
(On-Board Diagnostics) system
determines that critical emission
control systems have not been
completely diagnosed by the
system. The vehicle would
be considered not ready for
inspection. This can happen if
the 12 volt battery has recently
been replaced or if the 12 volt
battery has run down. The
diagnostic system is designed to
evaluate critical emission control
systems during normal driving.
This can take several days of
routine driving. If this has been
done and the vehicle still does
not pass the inspection for lack
of OBD II system readiness, your
dealer can prepare the vehicle
for inspection.
