Engine Coolant Heater (If Equipped)
In very cold weather,
0
F (
-18
C) or colder,
the engine coolant
heater can help.
You'll get easier
starting and better
fuel economy during
engine warm
-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
'At temperatures above 32
F (0
C), use of the coolant
heater is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on the
driver's side of the engine compartment, near the
power steering fluid reservoir.3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach, use a
heavy
-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug and store
the cord as it was before to keep it away from moving
engine parts. If you don't, it could be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
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 Indicator Light
The charging system light
will come on briefly when
you turn the ignition on, but
the engine is not running, as
a check to show you the
light is working.
Then it should go out once the engine is running. 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 accessory 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 heater/air conditioner.

Comfort Controls
This section tells you how to make your air system work
for you. Your comfort control system with air
conditioning uses ozone
-friendly refrigerant.
With these systems, you can control the heating,
cooling and ventilation in your vehicle. Your vehicle
also has a flow
-through ventilation system described
later in this section.
Heating System
If your vehicle does not have air conditioning, your
heater controls will look like this.Fan Knob
The fan know is located on the left of the control
panel. This control has four positions. To increase
airflow, turn the knob toward HI. To decrease airflow,
move it toward LO.
Temperature Knob
This knob is next to the fan knob. It controls the
temperature of the air flowing into your vehicle. Turn
the knob clockwise for warmer air. Turn the knob
counterclockwise for cooler air.
Function Knob
This knob is on the right of the temperature knob.
The function knob allows you to choose the direction of
air delivery.
OFF: This setting turns the system off.
(Vent): The air comes out at the vents on your
instrument panel.

3-5 Rear Heating System (Option)
You may have the optional rear heater. The three-speed
fan thumbwheel is to the right of the radio. Turn the
thumbwheel toward HIGH for higher airflow in the
rear area. Turn the thumbwheel to OFF to turn the
system off.
Rear Air Conditioning System (Option)
You may have rear air conditioning. The rear air
conditioning thumbwheel is located to the right of the
heater controls. Turn the thumbwheel toward HIGH for
higher airflow in the rear area. Turn the switch to OFF
to turn the system off.

3-6 Air Conditioning
Before using your vehicle's air conditioning, open the
windows to clear the vehicle of hot air. This reduces the
time it takes for your vehicle to cool down. Then keep
your windows closed for the air conditioner to work at
its best.
You can use MAX A/C with the temperature knob in
the blue area when it's really hot outside and you need
to cool the inside air quickly. MAX A/C lets in only a
little air from the outside.
If you first use MAX A/C, you can then use A/C with
the temperature knob in the blue area as soon as the
vehicle has cooled down, so outside air will be going
through your vehicle.
If your vehicle has rear air conditioning, setting it on LOW
may enhance the front air conditioning performance by
allowing trapped refrigerant in the rear lines to circulate.
The rear air conditioning system will only send cooled
air if the front system is on. It can still be used to
circulate air, even if the front system is off.
When the air conditioning, defrost or blend is on, you
may notice a slight increase or decrease in engine speed,
due to compressor operation. This is normal because the
system is designed to cycle the compressor on and off to
maintain the desired temperature.
Heating
On cold days, use the floor setting with the temperature
knob in the red area. Outside air will be brought in
through the floor ducts. The heater works best if you
keep your windows closed while using it.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See ªEngine Coolant Heaterº in the Index.
Defrosting
Use defrost to remove fog or ice from the windshield
quickly in extremely cold conditions. The temperature
knob should be in the red area and the fan control
toward high. The air conditioning compressor may
operate in this setting to dehumidify the air.
The blend setting is useful for cold weather with a large
number of passengers or very humid conditions to help
keep the windshield clear.

3-7 Rear Window Defogger (Option)
If your vehicle has this option, the rear window will
have lines running across the glass. These lines heat
your window.
For best results, clear the window of as much snow or
ice as possible before using the rear window defogger.
To turn on the rear window
defogger, find the button
located to the left of the
heater controls with the
defog symbol on it.
Press the button until the light comes on, then release it.The rear window defogger will only work when the
ignition is in RUN.
You can turn the defogger off at any time by pressing
the button again. The defogger will shut itself off after
several minutes so that the glass does not get too hot.
If the window still isn't clear, turn the defogger on again.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the defogger and the repairs
would not be covered by your warranty.
