Lights-on Reminder
If the headlights, parking lights, or cargo lights are left on
after the ignition is turned OFF, a chime will sound when
the driver's door is opened.
Fog Lights Ð If Equipped
The fog lights are turned ON by placing the
headlight rotary control in the parking light or
headlight position and pushing in the headlight
rotary control. The fog lights will operate only when the
parking lights are on or when the vehicle headlights are
on low beam. An indicator light located in the instrument
cluster will illuminate when the fog lights are on. The fog
lights will turn off when the switch is pushed a second
time, when the headlight switch is rotated to the OFF
position, or the high beam is selected.
Cargo Light Ð If Equipped
The cargo lights are turned ON by pressing on the
CARGO button. The interior lights will also turn on
when the cargo lights are on. The cargo lights will also
turn ON for 30 seconds when a key fob UNLOCK is
pressed, as part of the illuminated entry feature.
Cargo Light Switch

release the Trip Odometer button on the instrument
cluster. To reset the oil change indicator system (after
performing the scheduled maintenance) refer to the fol-
lowing procedure.
1. Turn the ignition switch to the ON position(Do not
start the engine).
2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.
17. Front Fog Light Indicator Ð If Equipped
This light shows when the front fog lights are ON.18. Malfunction Indicator Light
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing, the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.

Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it's rainy or humid. In most cases
turning on the air conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using MIX Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. Higher blower
speeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarettesmoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. For proper coolant type,
refer to ªRecommended Fluids and Genuine Partsº in
Section 7.
When using the air conditioner in extremely heavy traffic
in hot weather, especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.

²Any time you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
NOTE:When reinstalling the IOD fuse push firmly until
fully seated; the gauges in the instrument cluster will do
a full sweep when the ignition key is cycled to RUN. This
is a normal condition.
NOTE:
When the vehicle is shipped from the factory, the
IOD fuse is in the up, or extracted position. If the radio,
interior lamps, keyless entry, or other features do not work
with the key OFF, check the position of the fuse (or check
to see if the fuse is blown) to ensure that it is fully seated.
When the IOD fuse is extracted, the instrument cluster in
the odometer window will display9NO FUSE.º
