The charging system
light is on your
instrument cluster and will come on briefly
when you turn on the
ignition, but the
engine is not running,
as a check to show
you it is working.
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 charging system.
It could
indicate that you have problems with a 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.
Check Gages Light
This Check Gages
light is on the
instrument cluster and
will come on briefly
when you are starting
the engine.
If the light
comes on and stays on while you are driving,

Flow-Through Ventilation System
Your vehicle's flow-through ventilation system supplies outside a\
ir to the
inside of your vehicle when it is moving. With the side windows closed, air
will flow into the front air inlet grilles, through the vehicle, and out the rear
air exhaust valve. Outside air will also enter the vehicle whe\
n the heater
or
the air conditioning fan is running.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow, or any other
obstruction (such as leaves). The heater and defroster will w\
ork 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 HI for
a few moments before driving off. This helps clear the intake ducts of
snow and moisture, and reduces the chance of fogging the insid\
e 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 Air Vents
You will find air vents in the center and on the sides of your instrument
panel. 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.
Heater Controls
If your vehicle does
not have
air
conditioning, your
heater controls will
look like this.
The switch on the righthand side changes the fan speed. To increase the
fan
speed, push the switch upward toward HI. To decrease the fan speed, push
the switch downward toward
LO .
The upper knob changes the air temperature. Turn the knob right (clockwise)
for warmer
air. Turn the knob left (counterclockwise) for cooler air.
The lower knob changes the heater function and determines which\
outlets
the
air will flow through (instrument panel, defroster, heater, etc.).
3-3

Downloaded from www.Manualslib.com manuals search engine OFF: This setting turns off all heating functions. Some outside air will still
come out of the heater outlet whenever the vehicle is moving forward.
VENT Airflow is through the instrument panel vents. Set the upper knob to
the temperature desired. This setting is useful for mild outside temperatures,
when little heating
or cooling is desired.
BI-LEV: Outside air comes in through the heater floor vents and the
instrument panel vents. This setting is useful in cool weather \
with bright sunlight.
HEAT Heated air comes out through the heater floor vents and windsh\
ield
defroster vents. This setting is useful for cold weather.
BLEND: Airflow is divided equally between the heater floor vent and t\
he
windshield defroster vents. This setting is useful in cool weather when you
have fog or ice on the windshield or side windows.
DEF: This setting directs most air through the windshield defroster \
vents
and some through the heater vents. This setting is useful when\
you have fog
or ice on the windshield.
Heater/Air Conditioning Controls
If your vehicle has air
conditioning, your
heatedair conditioning
controls will look like
this.
Before using your vehicle's air conditioning, open the windows \
to clear the vehicle
of hot air.

speed, push the switch upward toward
HI. To decrease the fan speed, push
the switch downward toward

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:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam, try this for a minute
or
so:
1. If you have an air conditioner, turn it off.
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 “N” (Neutral).
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower for about ten 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 OFF THE ENGINE AND
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.
When you decide it’s safe to lift the hood,
here’s what you’ll see:
A. Coolant recovery tank
B. Radiator pressure
C. Engine fan
cap
If the coolant inside the coolant recovery tank is boiling, don’t do anything
else until it cools down.

level is lower, add more of the proper
mix through the filler neck until
the level reaches the base of the filler neck.
8. Then replace the
pressure cap.
At any time during
this
procedure if coolant begins to
flow out of the
filler neck,
reinstall the
pressure cap. Be sure the arrows
on pressure cap
line up like this.
P
' Engine Fan Noise
This vehicle has a clutched engine cooling fan. When the clutch is engaged,
the fan spins faster to provide more air
to cool the engine. In most every day
driving conditions the clutch is not engaged. This improves fuel economy
and reduces fan noise. Under heavy vehicle loading, trailer towing and/or
high outside temperatures, the fan speed increases when the clutch engages.
So you may hear an increase in fan noise. This is normal and should not be
mistaken as the transmission slipping or making extra shifts. It is merely the
cooling system functioning properly. The fan will slow down when
additional cooling is not required and the clutch disengages.
You may also hear this fan noise when you
start the engine. It will go away
as the
fan clutch disengages.
