Downloaded from www.Manualslib.com manuals search engine NOTICE:
After you’ve used the coolant heater, be sure to 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 weather, the kind of oil you have, and some other things.
Instead
of trying to list everything here, we ask that you contact a GM
dealer in the area where you’ll be parking your vehicle. The dealer can give
you the best advice for that particular area.
Automatic Transmission
.. . ...
There are several
different positions for
your shift lever.
P (Park) - This locks your rear wheels. It’s the best position to use
when you start your engine because your vehicle can’t move easily.

Flow-Through Ventilation System
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, 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.
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 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 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 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 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.
If your vehicle does not have air conditioning, there are air vents in each
kick panel below the instrument panel. Each vent has a handle to open and
close it.
Heater Controls
If your vehicle does
not have air
conditioning, your
heater controls will
look like this.
Fan Lever:
The lever at the top of the system has four positions. To increase the air
flow, move the lever toward HI. To decrease the air flow, move it toward
OFF.

Downloaded from www.Manualslib.com manuals search engine Temperature Lever:
The lever on the left of the system lets you select the temperature of the air
flowing into your vehicle. Move the lever up for warmer air. Move the lever
down for cooler air.
Mode Function Lever:
The lever on the right of the system can be moved to three different heating
functions.
DEFROST: This setting 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.
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 and at your
front side windows.
Heating/Air Conditioning Controls
If your vehicle has air
conditioning, your
heating/air
conditioning controls
will look like this.
Before using
your vehicle’s air conditioning, open the windows to clear me
vehicle of hot air.
Fan Lever:
The lever at the top has four positions. To increase the air flow, move the
lever toward
HI. To decrease the air flow, move it toward LO.

BI-LEV A/C: With this, outside air comes in through the heater floor vent
and the instrument panel vents. This setting is useful
in cool weather with
bright sunlight.
NORM A/C: This setting cools the outside air. If you first use MAX, use
NORM 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 lets in only a little air from the outside. You can use MAX at
first when it’s really hot outside and you need to cool off quickly.
NOTICE:
If vehicle is parked with function lever in MAX A/C position
and on an incline with the right side lower than the left, t\
hen water may leak into the passenger compartment in an unusually
heavy rain.
J
OFF: The blower is off, but air still will come from outlets at the front of
your vehicle. The system
will try to keep the air at the chosen temperature.
Engine Coolant Heater (Engine Block Heater)
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 Window Defogger
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 first.

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This saves fuel. When you run
the engine, make it go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat that
you get and it keeps
the battery charged. You will need a well-charged battery (or batteries)
to
restart the vehicle, and possibly for signaling later on with your headlights.
Let the heater run for awhile.
Then, shut the engine
off and close the window almost all the way to
preserve the heat. Start the engine again and repeat this only when you feel
really uncomfortable from the cold. But
do it as little as possible. Preserve
the fuel as long as you can.
To help keep warm, you can get out of the
vehicle and do some fairly vigorous exercises every half hour or
so until
help comes.
Recreational Vehicle To wing
(Four-wheel Drive
Only)
If your vehicle has 4-wheel drive, you may tow it behind another vehicle
providing it does
not have the optional electronic shift transfer case.
Recreational vehicle towing is not recommended for vehicles
with the optional electronic shift transfer case because the
electronic shift has no neutral position.

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.
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
3. If you’re in a traffic jam, shift to “N” (Neutral).
window as
necessary.
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
B. Radiator pressure
C. Engine fan tank
cap
If the
coolant inside the coolant recovery tank is boiling, don’t do anything
else until
it cools down.

Downloaded from www.Manualslib.com manuals search engine B'
The coolant level should be at or above the ADD mark. If it isn't, you may
have a leak
in the radiator hoses, heater hoses, radiator, water pump or
somewhere else
in the cooling system.
NOTICE:
Engine damage from running your engine without coolant isn't
covered by your warranty.
If there seems to be no leak, start the engine again. See if the fan speed
increases when idle speed is doubled
by pushing the accelerator pedal down.
If
it doesn't, your vehicle needs service. Turn off the engine.
How to Add Coolant to the Coolant Recovery Tank
If you haven't found a problem yet, but the coolant level isn't at or above
the
ADD mark, add a 50/50 mixture of clean water (preferably distilled)
and a proper antifreeze at the coolant recovery tank. (See "Engine Coolant"
in the Index for more information about the proper coolant mix.)
