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

The red charging
system light is above
your oil temperature
gage 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 t\
his 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.

GAGES
This amber CHECK
GAGES light is above
the
fuel gage 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, check your coolant
temperature and engine oil pressure gages to see
if they are in the warning
zones.

Engine Coolant Temperature Gage
I

0
rc E- -
This gage shows the
engine coolant
temperature.
If the
gage pointer moves into the red area, your
engine
is too hot!
It means that your engine coolant has overheated. If you have bee\
n
operating your vehicle under normal driving conditions, you shou\
ld pull off
the road, stop your vehicle and turn
off the engine as soon as possible.
Hot Coolant Can Burn you Badly! In Problems On The Road, this manual
explains what to do. See “Engine Overheating” in the Index.
Oil Pressure Gage
40
The oil pressure gage
shows the engine oil
pressure in psi (pounds per square
inch) when the engine
is running. Canadian
vehicles indicate
pressure in kPa (kilopascals).
Oil pressure may vary with engine speed, outside temperature and oil
viscosity, but readings above the low pressure zone indicate the normal
operating range.
A reading in the low pressure zone may be caused by a dangerously low oil
level or other problems causing low oil pressure.

Downloaded from www.Manualslib.com manuals search engine The upper knob changes the air temperature. Turn the knob clockwise for
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.

Here are some tips for winter driving:
Have your vehicle in good shape for winter. Be sure your engine
coolant mix is correct.
You may want to put winter emergency supplies in your vehicle.
Include an ice scraper, a small brush or broom, a supply of windshield
washer fluid, a rag, some winter outer clothing, a small shovel,
a flashlight,
a red cloth, and a couple of reflective warning triangles. And,
if you will be
driving under severe conditions, include a small bag
of sand, a piece of old
carpet or a couple
of burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the road probably have
good traction.
However, if there is snow or ice between your tires and the road,
you can
have a very slippery situation. You’ll have a lot less traction or “grip” and
will need to be very careful.

Downloaded from www.Manualslib.com manuals search engine 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) (or the manual transmission
out of gear and the parking brake applied) for a few minutes before turni\
ng
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, or into
gear for a manual transmission. Then turn your wheels into the curb if \
facing downhill or into traffic if 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 \
then
shift into PARK (P), or REVERSE
(R) for a manual transmission.
5. If you have a four-wheel-drive vehicle with a manual transfer case
shift lever, be sure
the transfer case is in a drive gear - not in
NEUTRAL
(N).
6. Release the parking brake.

If Steam Is Coming From Your Engine
NOTICE:
If your engine catches fire because you keep driving with no
coolant, your vehicle can be badly damaged. The costly repairs
would not be covered by your warranty.

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.
