Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on,
the exterior lamps will turn off about 10 minutes after
the ignition is turned to OFF. This protects against
draining the battery in case the headlamps or parking
lamps have been left on. The battery saver does
not work if the headlamps are turned on after the
ignition is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn
the lamps back on.
Instrument Panel Brightness
The lever for this
feature is located on the
overhead console.
Slide the lever toward the symbol to brighten the lights
or away from it to dim them.
If you slide the lever all the way toward the symbol past
the resistance point, the interior lamps will come on.
To turn them off, slide the lever back toward the
minimum brightness setting.

Entry Lighting
The entry lighting system turns on the reading and dome
lamps and the backlighting to the exterior lamp control
when a door is opened or if the Remote Keyless Entry
(RKE) transmitter unlock button is pressed. If activated by
the (RKE), the lighting will remain active for about
25 seconds. The entry lighting system uses the light
sensor on the instrument panel; so it must be dark
outside in order for the lamps to turn on. The lamps turn
off about 25 seconds after the last door is closed. They
will dim to off if the ignition key is turned to ON, or
immediately turn off if the power locks are used.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when
the key is in the ignition and the headlamps are on.
This feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness outside
and the parking lamps are active, the instrument
panel displays can be adjusted by sliding the instrument
panel brightness lever toward the symbol to brighten
or away from the symbol to dim the lighting.
Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door is
opened.
For manual operation, press the button next to each
lamp to turn it on or off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Accessory Power Outlet(s)
With accessory power outlets, you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
The front accessory power outlet is located in the
ashtray on the instrument panel below the climate
control system. The outlet will have a cigarette lighter if
your vehicle has this option. Remove the cigarette
lighter to access the outlet.
The rear accessory power outlet is located on the back
of the center console.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet. If it

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog from
your windshield. Use the defog mode to clear the
windows of fog or moisture and warm the passengers.
Use the defrost mode to remove fog or frost from
the windshield more quickly.
yNz(Mode):Press this button until defog appears
on the display.
-(Defog):This mode directs the air between the
windshield, oor outlets and side windows. When this
mode is selected, the system turns off recirculation and
runs the air-conditioning compressor unless the outside
temperature is at or below freezing. If recirculation mode
is selected while in defog mode, it will be cancelled after
10 minutes.
If there is fog on the side windows, turn the thumbwheel
on the outboard outlets to the side window defog position.
SeeOutlet Adjustment on page 3-28for more
information.
0(Defrost):Pressing defrost directs most of the air
to the windshield, with some air directed to the side
windows. In this mode, the system will automatically turn
off recirculation and run the air-conditioning compressor,
unless the outside temperature is at or below freezing.
This mode may also cause the fan speed and air
temperature to increase.
If there is fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. SeeOutlet Adjustment on page 3-28
for more information. Do not drive the vehicle until all the
windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in ON.

Passenger Compartment Air Filter
The passenger compartment air lter traps most of the
pollen from the air entering your vehicle. Like your
vehicle’s engine air cleaner/lter, it needs to be changed
periodically. SeeScheduled Maintenance on page 6-4.
Using the climate control system without the passenger
air lter installed may allow water or other debris to
enter the system. This could cause a water leak
or noises. Make sure to install a new air lter after
removing the old one.
The passenger compartment air lter is located
underneath the hood below the windshield wiper arm on
the passenger’s side of the vehicle. SeeEngine
Compartment Overview on page 5-12for more
information on location.Use the procedure listed below to replace the passenger
compartment air lter:
1. Turn the ignition to ON with the engine off.
2. Turn on the windshield wipers and turn them off
again when the wipers are straight on the
windshield.
This allows you access to the leaf screen. The
passenger compartment air lter is located under
the leaf screen.
3. Open the hood to access the engine compartment.
SeeHood Release on page 5-11for more
information.
4. Remove the four screws that hold the leaf screen in
place and lift off the screen by lifting and sliding
toward the center of the vehicle.
5. Pull out on the two tabs located on each end of the
lter cover.
6. Lift the lter cover off by pulling it straight upward.
7. Remove the old lter and insert a new one.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which monitors
operation of the fuel,
ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
