The cigarette lighter is on the left of the engine cover console. To use the
lighter, press it in all the way and let go. When it’s ready, it will
pop back by
itself.
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.
To remove the smaller
ashtrays on each
sidewall, press down
on the tabs inside and
pull out.
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.

Standard Cluster Digital Cluster
If you have the standard cluster, you have a gage that shows the engine
coolant temperature. If the gage pointer moves to the
“H” (red) side, your
engine is
too hot!
It means that your engine coolant has overheated. If you have been
operating your vehicle under normal driving conditions, you should pull off
the road, stop your vehicle and turn
off the engine as soon as possible.
If you have
a digital cluster, a box around the temperature symbol will also
flash when your engine is too hot.
In “Problems on
the Road,” this manual explains what to do. See “Engine
Overheating”
in the Index.

Downloaded from www.Manualslib.com manuals search engine DEFROST-The setting with the defrost symbol operates the defroster. Most
of the air comes out near the windshield, with some going to the floor vents and
front side windows. Use
this when you get fog or ice on the windshield.
HTR (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. This is best for cold weather.
VENT
- The air comes out at the vents on your instrument panel.
BLEND (Position
1) - With this setting, the heated outside air comes out
both
the heater vents and defroster vents. The lever can be positioned
anywhere between to adjust the proportion of air coming through each
vent.
Adjust the temperature lever for warmer or cooler air.
BLEND (Position
2) - With this setting, the heated outside air comes out
both the instrument panel vents and heater vents. The lever can be
positioned anywhere between
to adjust the proportion of air coming through
each
vent. Adjust the temperature lever for warmer or cooler air.
Heater/Air Conditioning Controls
If your vehicle has air
conditioning, your
heatinghir
conditioning controls
will
look like this.
Before using your vehicle’s air conditioning, open the windows to clear the
vehicle
of hot air. Close the windows when using the system.
Fan Lever- The top lever has five positions.
To increase the air flow, move the
lever toward
HIGH. To decrease the air flow, move the lever toward OFF.
Temperature Lever
- This lever is below the fan lever and selects the
temperature of the air flowing into your vehicle. Move the lever up for
warmer air. Move the lever down for cooler air.
Function Lever
- This lever is below the fan lever and can be moved to
seven different functions.
DEFROST
- The setting with the defrost symbol operates the defroster.
Most of the air comes out near the windshield,
with some going to the floor
vents and side window defrost vents. Use this when you get fog or ice on
the windshield. The A/C compressor may operate in this setting to
dehumidify the air.

Downloaded from www.Manualslib.com manuals search engine BLEND - With this setting, the heated outside air comes out both the
heater
vents and defroster vents, with some air coming through the side
window vents. Adjust the temperature lever
for warmer or cooler air. This
setting
is useful for cold weather with a large number of passengers or very
humid conditions
to help keep the windshield clear. The A/C compressor
may operate in this setting
to dehumidify the air.
HTR (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. This
is best for cold weather.
VENT
- The air comes out at the vents on your instrument panel. The air
conditioner will not run. Adjust the temperature lever for warmer or cooler air.
BI-LEV A/C - With this, outside air comes out through the heater floor
vent and the instrument panel vents. If you move your temperature control
lever between cold and hot, cooler air
will come out of the upper vents
while warmer air comes
out of the floor vent. This setting is useful in cool
weather with bright sunlight.
NORM A/C - This setting cools the outside air. If you first used MAX
A/C, use NORM A/C
as soon as the vehicle has cooled down, so outside air
will be going through your vehicle.
MAX A/C -This cools the air the fastest. Move
the other lever all the way to
Cold. MAX A/C lets in only a little air from the outside. You can use MAX A/C
at first when
it's really hot outside and you need to cool off quickly.
When
the air conditioning, defrost or BLEND is on, you may notice a slight
increase or decrease in engine speed, due
to compressor operation.
Engine Coolant Heater (Option)
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.
Rear Heater (Option)
You may have the
optional rear heater.
The three speed fan
switch is above the
radio. Slide
the lever
toward
HI for warmer
air in the rear area.
Move the switch to
OFF to turn the
system off.

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 transmission overheating.
When towing at high altitude
on steep uphill grades, consider the following:
Engine coolant will boil at
a lower temperature than at normal altitudes. If
you turn your engine off immediately after towing at high altitude on steep
uphill grades, your vehicle may show signs similar to engine overheating.
To avoid this, let the engine run while parked (preferably on level ground)
with the automatic transmission
in PARK (P) for a few minutes before
turning the engine off. If you do get the overheat warning, see “Engine
Overheating”
in the Index.
Parking on Hills
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) yet. Turn your
wheels into the curb when facing downhill and away from the curb
when facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel 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 to
5. Release the regular brakes.
PARK (P).
When You Are Ready to Leave After Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.

Downloaded from www.Manualslib.com manuals search engine What to Use
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants”
in the Index.
Engine Coolant
The following explains your cooling system and how to add coolant when it
is low. If you have a problem with engine overheating, see “Engine
Overheating”
in the Index.
The proper coolant
for your vehicle will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 262 OF ( 1 28 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.
What to Use
Use a mixture of one-half clean wafer (preferably distilled) and one-half
antifreeze that meets
“GM Specification 6038-M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to “GM
Specification 6038-M. Use
GM Coolant Supplement (Sealer) with a
complete coolant flush and refill.
If you use this mixture, you don’t need to
add anything else.

Downloaded from www.Manualslib.com manuals search engine Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi (105 kPa) pressure-type cap and
must be tightly installed to prevent coolant
loss and possible
engine damage from overheating. Be sure the arrows on the cap \
line up with the overflow tube on the radiator filler neck.
Thermostat
~ When you replace
1 your radiator pressure cap, a
GM cap is
1 recommended. See
l “Service Replacement
I Parts and Filler
Recommendations” in
the Index.
Engine coolant temperature is controlled
by a thermostat in the engine
coolant system. The thermostat stops
the flow of coolant through the
radiator until the coolant reaches
a preset temperature.
When
you replace your thermostat, an AC@ thermostat is recommended.
