Downloaded from www.Manualslib.com manuals search engine A CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in
PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is
running unless you have to. If you’ve left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won’t move, even when you’re on
fairly
level ground, always set your parking brake and
move the shift lever to
PARK (P).
Locking Rear Axle (Option)
If you have this feature, your locking rear axle can give
you additional traction on snow, mud, ice, sand or
gravel. It works like a standard axle most of the time,
but when one
of the rear wheels has no traction and the
other does, this feature will allow the wheel with
traction to move
the vehicle.
All-Wheel Drive (Option)
If your vehicle has
all-wheel drive, your
engine’s driving power
is sent to all four wheels
for extra traction.
Follow
the proper steps to be sure your vehicle won’t
move. See “Shifting Into
PARK (P)” in the Index.
If you’re pulling a trailer, see “Towing a Trailer’’ in
the Index.
This is like four-wheel drive, but there
is no separate
lever or switch
to engage or disengage the front axle.
It is fully automatic, and adjusts itself as needed for
road conditions.

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 heatedair conditioner.
Voltmeter
When your engine is not
running, but the ignition is
on (in the RUN position),
the gage shows your
battery’s state
of charge in
DC volts.
When the ignition is running, the gage shows the
condition
of the charging system. Readings between the
low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a
large number
of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system
to create maximum power.

Downloaded from www.Manualslib.com manuals search engine Comfort Controls
This section tells you how to make your air system
work for you. Your comfort control system uses
ozone-friendly
R- 134a 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/Air Conditioning System
If your vehicle has air conditioning, your heating/air
conditioning controls will look like this.
Fan Knob
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 selects the
temperature of the air flowing into your vehicle. Move
the knob toward the right for warmer air. Move the knob
toward the left for cooler air.
Function Knob
This knob is next to the temperature knob.
OFF: This setting turns the system off.
MAX NC: This cools the air the fastest, by
recirculating the inside air. Move the temperature knob
all the way to the left.
A/C: This setting brings in outside air and cools it.

+@ BI-LEVEL: This setting brings in outside air
and blows
it out through the heater floor vents and the
instrument panel
vents. If you move the temperature
knob between hot and cold, cooler air will come
out of
the upper vents while warmer air comes out of the floor
vent. The air conditioning compressor may operate in
this setting to cool the air.
/J VENT The air comes out at the vents on your
instrument panel. The air conditioning compressor will
not run in this position. Adjust the temperature knob for
warmer or cooler air.
+' HEATER: Most of the air comes out near the
floor. The rest comes
out from the defroster vents under
the windshield and at the front side windows.
+, BLEND: With this setting, the heated outside air
comes out both the heater vents and defroster vents.
Adjust the temperature knob for warmer or cooler air.
The air conditioning compressor may operate in this
setting
to dehumidify the air.

Downloaded from www.Manualslib.com manuals search engine Rear Air Conditioning System (Option) 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.
You may have rear air conditioning. The rear air
conditioning switch is located
to the right of the heater
controls. Turn the switch toward
HIGH for higher
airflow in the rear area. Turn the switch to the
OFF
position to turn the system off.
3-5

Downloaded from www.Manualslib.com manuals search engine If your vehicle has rear air conditioning, setting it on
LOW may enhance the front
A/C 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 keep the desired temperature.
Heating
On cold days, use HEATER with the temperature knob
in the red area. Outside air will be brought in through
the floor outlets. 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 “Engine Coolant Heater” 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.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use VENT
to direct outside air
through your vehicle. Air will flow through the
instrument panel vents.
Your vehicle’s flow-through ventilation system supplies
outside air to the inside of your vehicle when it is
moving. With the side windows closed, air will flow into
the front air inlet grilles at the base of the windshield,
through the vehicle and
out the rear air exhaust valve.
Outside air will also
enter the vehicle when the heater or
the air conditioning fan is running.
3-6

Downloaded from www.Manualslib.com manuals search engine Your vehicle has air vents near the center and on the
sides of the instrument panel that allow you to adjust the
direction and the amount of airflow inside the vehicle.
Move the dial on the vent up or down to direct airflow
to your preference. Increase or reduce the amount of
airflow by opening and closing the louvers. The vents
rotate to direct the airflow from side to side.
When you close a vent, it will increase the flow of air
coming out of any vents that are open. If you
have rear heating or rear air conditioning, you
will have adjustable vents in the rear of the vehicle to
help direct the airflow. The rear air conditioning vents are located in the headliner at the rear
of the vehicle.
The rear heating vents are located next to the second
and third seat
on the driver’s side of the vehicle, near the
floor.
You can move the vents to direct the flow of air,
or close the vents altogether. When you close a vent, it
will increase the flow of air coming out of any vents that
are open.
Ventilation Tips
e
e
a
Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work
far better, reducing the
chance
of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the
blower fan to HIGH for
a few moments before
driving off.
This helps clear the intake ducts of snow
and moisture, and reduces the chance of fogging the
inside of your windows.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

Downloaded from www.Manualslib.com manuals search engine If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
0 Tow a trailer. See “Driving on Grades” in the Index.
If
you get the overheat warning with no sign of steam,
try this for a minute or
so:
I. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- DRIVE (D).
If you no longer have the overheat warning, you
can drive. Just
to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
If
the warning continues, pull over, stop, and park
your vehicle right away.
If there’s still
no sign of steam, push the accelerator
until the engine speed is about twice as fast as normal
idle speed. Bring the engine speed back
to normal idle
speed after two or three minutes. Now see if the warning
stops. But then,
if you still have the warning, turn ofs
the engine nncl get everyone out of the vehicle until it
cools down.
You
may decide not to lift the hood but to get service
help right away.
