2-43
A flashing DRL telltale indicates a possible burned out
headlamp, or that the vehicle may need service to repair
a stuck DRL relay.
When the DRL are on, only your high
-beam headlamps
will be on at reduced brightness. The taillamps,
sidemarker and other lamps won't be on. Your
instrument panel won't be lit up either.
When you turn on the headlamp switch, your high
-beam
headlamps will go out, and your headlamps will come
on. The other lamps that come on with your headlamps
will also come on.
When you turn off the headlamp switch, the regular
lamps will go off, and your high
-beam headlamps will
come on at reduced brightness.
To idle your vehicle with the DRL off, set the parking
brake. The DRL will stay off until you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps (If Equipped)
Use your fog lamps for better vision in foggy or
misty conditions.
The switch for your fog lamps is next to the instrument
panel intensity control.
Push the top of the switch to turn the fog lamps on. Push
the bottom of the switch to turn the fog lamps off.
When using fog lamps, the parking lamps or low
-beam
headlamps must be on.

2-66 Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag's electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensor, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see ªAir
Bagº in the Index.
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Charging System Light
The charging system light
will come on briefly when
you turn on the ignition, and
the engine is not running, as
a check to show you it
is working.
Then it should go out when the engine is started.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
It could indicate that you have a loose generator drive
belt, or another electrical problem. Have it checked right
away. Driving while this light is on could drain
your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.

This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.If the light stops flashing and remains on steady, see ªIf
the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index. The
diagnostic system can determine if the fuel cap has been
left off or improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the atmosphere. A
few driving trips with the cap properly installed should
turn the light off.
Did you just drive through a deep puddle of water?

Comfort Controls
This section tells you how to make your air system work
for you. The optional climate control system with air
conditioning uses ozone
-friendly R-134a refrigerant.
With these systems, you can control the ventilation
and heating in your vehicle. Your vehicle also has
the flow
-through ventilation system described later
in this section.
Standard Climate Control System
Fan Knob
The left knob selects the force of air you want. Turn the
knob clockwise to increase fan speed and
counterclockwise to decrease fan speed. To turn the fan
off, turn the mode knob all the way counterclockwise to
OFF. In any other setting, the fan will run continuously.
Temperature Knob
The center knob changes the temperature of the air
coming through the system. Turn this knob toward red
(clockwise) for warmer air. Turn it toward blue
(counterclockwise) for cooler air.
Mode Knob
The right knob has several settings to control the
direction of airflow. For each setting, set the temperature
to a comfortable setting.
VENT: This setting brings in outside air and
directs it through the instrument panel outlets.
BI-LEVEL: This setting brings in outside air and
directs it two ways. Some air is directed through the
instrument panel outlets. Most of the air is directed
through the floor ducts and a little to the defrost and side
window vents.

3-3
FLOOR: This setting sends most of the air
through the ducts near the floor. The rest comes out of
the defroster and side window vents.
DEFOG: This setting allows half of the air to go
to the floor ducts and half to the defroster and side
window vents.
DEFROST: This setting directs most of the air
through the defroster and side window vents. Some of
the air goes to the floor ducts.
Climate Control System with Air
Conditioning (If Equipped)
Fan Knob
The left knob selects the force of air you want. Turn the
knob clockwise to increase fan speed and
counterclockwise to decrease fan speed. To turn the fan
off, turn the mode knob all the way counterclockwise to
OFF. In any other setting, the fan will run continuously.
The fan must be on to run the air conditioning compressor.

the air in the vehicle.
Air Conditioning Compressor Button
Press the A/C button to operate the air conditioner
compressor. The indicator light above the button will
glow when the air conditioning compressor is running.
You don't have to press the button to run the compressor
in MAX or DEFROST.
Air Conditioning (If Equipped)
On very hot days, open the windows long enough to let hot,
inside air escape. This reduces the time it takes for your
vehicle to cool down, which should help fuel economy.
For quick cool
-down on very hot days, use MAX with
the temperature knob all the way in the blue area. If this
setting is used for long periods of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use VENT with the
temperature knob in the blue area and the A/C button
pushed in. The system will bring in outside air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI
-LEVEL with the temperature knob in
the middle and the A/C button pushed in. The system
will bring in outside air and direct slightly warmer air to
your lower body. You may notice this temperature
difference more at some times than others.

3-5 Heating
On cold days, use FLOOR with the temperature knob all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
Your vehicle has heat ducts that are directed toward the
rear seat. Keep the area under the front seats clear of
obstructions so the heated air can reach the rear
seat passengers.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
DEFROST with the temperature knob all the way in the
red area. To warm passengers while keeping the
windows clean, use DEFOG.
To defog the side windows, set the right control to
BI
-LEVEL and the fan control to the highest setting.To defog the side windows while using the air
conditioner, set the right control to BI
-LEVEL, the fan
control to the highest setting, and press the A/C button.
For both systems, aim the side vents toward the side
windows. For increased airflow to the side vents, close
the center vents.
Rear Window Defogger (If Equipped)
The rear window defogger
uses a warming grid to
remove fog from the
rear window.
Press the button to turn the
defogger on. It will turn
itself off after about
10 minutes.
If you turn it on again, the defogger will only run for
about five minutes before turning off. You can also turn
it off by pressing the button again.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
