Ashtray and Cigarette Lighter
(If Equipped)
To use the lighter, just push it in all the way and let go.
NOTICE:
Don't put papers and other things that burn
into your ashtrays. If you do, cigarettes or
other smoking materials could set them on fire,
causing damage.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
You can also remove the cigarette lighter to plug in
additional accessories. Be sure to follow the proper
installation instructions that are included with any
electrical accessory you install.
Sun Visors
To block out glare, you can swing down the visors. You
can also remove them from the center mount and swing
them to the side, to block out glare from the side.
Your vehicle is equipped with sun visors that can be
extended by sliding the visor on the support rod, to give
twice the coverage.
Visor Vanity Mirror
Swing down the sun visor and lift the cover to expose
the vanity mirror.

2-66 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into the
red area, the light comes on
and you hear a chime, your
engine is too hot. It means
that your engine coolant has
overheated.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
This light comes on briefly
when you turn your ignition
on.
If this light comes on and stays on and you hear a chime,
the coolant level in your vehicle is low. See ªEngine
Coolantº in the Index. If the light is on along with an
overheat warning, you may have a serious overheating
problem. See ªEngine Coolant Temperature Gageº listed
previously.
NOTICE:
Damage to your engine from neglected coolant
problems can be costly and is not covered by your
warranty.
See ªEngine Overheatingº in the Index for information
on what to do. Your vehicle should be serviced as soon
as possible.

Comfort Controls
With this system, you can control the air conditioning,
ventilation and heating in your vehicle. Your vehicle
also has the flow
-through ventilation system described
later in this section.
Climate Control System with Air Conditioning
Fan Knob
The left knob regulates the fan speed. To select the force
of air you want, turn the knob.
Temperature Knob
The center knob regulates the temperature of the air
coming through the system.Mode Knob
The right knob changes the functions of the system.
The available modes are the following:
(Vent): In this position most of the airflow comes
through the instrument panel outlets. A small amount of
air comes through the floor outlets. Set the center knob
to the desired temperature for comfort.
(Bi-Level): In this position the airflow comes
through the instrument panel outlets and through the
floor outlets. Set the center knob to the desired
temperature.
(Floor): In this position most of the airflow comes
through the floor outlets. The rest of the air comes
through the windshield and side window vents. Set the
center knob to the desired temperature for comfort.
(Defog): This position divides the airflow between
the floor outlets and the windshield defroster vent. The air
conditioning compressor will run automatically in this
position when it is needed to help dry the air in the vehicle.
(Front Defroster): This position directs most of
the airflow through the windshield defroster vent. Some
of the air goes to the floor outlets. The air conditioning
will run automatically in this position when it is needed
to help dry the air in the vehicle.

3-4
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 pressed in. The system
directs slightly warmer air to your lower body.
Heating
On cold days, use floor mode and the outside air button
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 outlets.
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 Windows
Your system has two settings for clearing the front and
side windows. For each setting, adjust the temperature
knob as desired.To defrost the front window quickly, turn the
temperature knob all the way in the red area. Use front
defroster and adjust the fan to the highest speed. To
warm passengers while keeping the front window clean,
use defog. When you switch to defog or defrost modes
your system will automatically move from recirculation
into outside air. When you move the mode knob back to
vent or bi±level, the system will move back into
recirculation. When the car is turned off and back on the
system will default to outside air automatically.
The recirculation setting in cold weather should be used
only for outside odor control so that fog formation on
the windows is reduced.
Your vehicle is equipped with side window defogger
vents. The side window defogger vents are located
above the side instrument panel vents. To defrost the
side windows, turn the temperature knob all the way in
the red area. Use floor mode and adjust the fan to the
highest speed.
To defog the side windows while using air conditioning,
use bi
-level and adjust the fan to the highest speed and
press the A/C button so that the indicator light is glowing.
For added airflow to the side windows, aim the side vents
toward the windows and close the center vents.

3-5 Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The button is located
at the bottom, on the right
of the climate controls.
Press the defogger button. The indicator light will glow.
The rear window defogger will turn itself off after about
10 minutes after the first time the button is pressed, and
after five minutes each additional time the button is
pressed. You can turn the defogger off by pressing the
button again or turning off the ignition.Do not attach a temporary vehicle license across the
defogger grid on the rear window.NOTICE:
Don't use a razor blade or anything else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use vent mode and direct outside air
through your vehicle. Your vehicle also has the
flow
-through ventilation system.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.

4-42 Driving On Grades
Reduce speed and shift to a lower gear before you
start down a long or steep downgrade. If you don't
shift down, you might have to use your brakes so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around 45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
Parking on Hills
CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but don't shift into
PARK (P) for an automatic transaxle or into a
gear for a manual transaxle, yet. When parking
uphill, turn your wheels away from the curb.
When parking downhill, turn your wheels into
the curb.
2. Have someone place chocks under the trailer wheels.
3. When the chocks are in place, release the regular
brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake and shift into PARK (P) for an automatic
transaxle or REVERSE (R) for a manual transaxle.
5. Release the regular brakes.
