I NOTICE:
If you drive too quickly through deep puddles or standing water,
water can come in through your engine's air intake and badly
damage your engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you can't avoid
deep puddles
or standing water, drive through them very slowly.
Engine Coolant Heater (Option)
4.3 Liter:
A. Engine coolant heater cord strap
B. Engine coolant heater cord cap
In very cold weather, 0°F (-1 8 "C) or colder, the engine coolant heater can
help. You'll get easier starting and better fuel economy during engine
warm-up. Usually, the coolant heater should be plugged in a mi\
nimum
of
four hours prior to starting your vehicle.
To
use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 1 10-volt outlet.

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 your
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
c There are several
different positions for
your shift lever.
If your vehicle is equipped with automatic transmission, it now features an
electronic shift position indicator within the instrument cluster. This display
must be powered anytime the shift lever is capable of being moved out of
the
PARK (P) position. This means that if your key is in the OFF position,
but not locked, there will be a small current drain on your battery which
could discharge your battery over a period of time. If
you have a need to

warmer air. Turn the knob counterclockwise for cooler air.
The lower knob selects the heater
or air conditioning function and
determines which outlets the air will flow through (instrument panel,
defroster, heater, etc
.).
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.
MAX A/C - Air inside your vehicle is recirculated to maximize your air
conditioner’s performance and your vehicle’s fuel economy. This setting
cools the air the fastest and should be used to keep “unwanted odors” and/or
dust from entering the vehicle.
NORM A/C - This setting cools outside air and directs it through the
instrument panel vents. This setting is useful for normal cooling on hot
days.
BI-LEV A/C
- Air is delivered through the heater floor vents as well as
the instrument panel vents. This setting is useful in cool weather with bright
sunlight.
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. The air conditioner
does not run.
HEAT
- Heated air comes out through the heater floor vents and
windshield defroster vents. This setting is useful for cold weather.
BLEND
- Airflow is divided equally between the heater floor vent and the
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.
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.

L
L
I‘ -a
Your vehicle’s ventilation system supplies outside air to the insi\
de 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.
0 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.
0 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 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 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.
Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle is stationary or anchored.
NOTICE:
Operating a power winch with an automatic transmission in
PARK (P) or a manual transmission in gear may damage the
transmission. Always put the transmission in a Neutral position \
while operating a power winch.
I
Use the regular brakes, set the parking brake or block the wheels to keep
your vehicle from rolling.
If your vehicle is equipped with an airbag, see "Adding Equipment to Your
Air Bag-Equipped Vehicle" in the Index.

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:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
0 Idle for long periods in traffic.
e 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:
1. 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
- AUTOMATIC OVERDRIVE (@) or
DRIVE (D) for automatic transmissions.
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 oflthe 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.

Downloaded from www.Manualslib.com manuals search engine If the coolant inside the coolant recovery tank is boiling, don’\
t do anything
else until
it cools down.
The coolant level should be at 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.

Downloaded from www.Manualslib.com manuals search 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 ADD, 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.) ..
NOTICE:
In cold weather, water can freeze and crack the engine, radiat\
or,
heater core and other parts. Use the recommended coolant.
