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 9-39. 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 9-38.
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).
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. See your
dealer for assistance in verifying
proper operation of the
malfunction indicator lamp.
.The OBD II (On-Board
Diagnostics) system determines
that critical emission control

Lighting 6-3
The DRL system makes the
low-beam headlamps come on at a
reduced brightness when the
following conditions are met:
.The ignition is in the ON/
RUN mode.
.The exterior lamp control is
in AUTO.
.The engine is running.
When the DRL are on, only the
low-beam headlamps, at a reduced
level of brightness, will be on. The
taillamps, sidemarker, instrument
panel, and other lamps will not
be on.
The headlamps automatically
change from DRL to the regular
headlamps depending on the
darkness of the surroundings. The
other lamps that come on with the
headlamps will also come on.
When it is bright enough outside,
the headlamps go off and the DRL
come on. To turn the DRL lamps off or on
again, turn the exterior lamp control
to
Oand then release. For vehicles
first sold in Canada, the DRL lamps
cannot be turned off.
Automatic Headlamp
System
When it is dark enough outside and
the exterior lamp control is in the
automatic position, the headlamps
come on automatically. See Exterior
Lamp Controls on page 6-1.
The vehicle has a light sensor on
top of the instrument panel. Make
sure it is not covered, or the
headlamps will be on when they are
not needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.

If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for the
lamps coming on varies based on
wiper speed. When the wipers are
not operating, these lamps turn off.
Move the exterior lamp control to
P
or;to disable this feature.

[(Floor): Air is directed to the
floor outlets, with some air directed
to the rear outlets.
W(Defog): This mode clears the
windows of fog or moisture. Air is
directed to the floor, windshield, and
side window outlets.
1(Defrost): This mode clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield and side window outlets.
Do not drive the vehicle until all
windows are clear.
In defrost or defog mode, excessive
air conditioning use can cause the
windows to fog. If this happens,
change the air delivery mode to
Y
and reduce the fan speed.
#(Air Conditioning): If equipped

the following:
1. Open the windows to let hot air
escape.
2. Press
M.
3. Press
#.
4. Select the coolest temperature.
5. Select the highest
Aspeed.
Using these settings together for
long periods of time may cause the
air inside the vehicle to become too
dry. To prevent this from happening,
after the air in the vehicle has
cooled, turn the recirculation
mode off.
M(Recirculation): This mode
recirculates and helps to quickly
cool the air inside the vehicle. It can
be used to reduce the entry of
outside air and odors.
