The red charging
system indicator 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 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.

Engine Coolant Temperature Gage
210
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 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.
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
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 aangerously low oil
level or other problems causing low oil pressure.

Downloaded from www.Manualslib.com manuals search engine 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.

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) (or the manual transmission
out of gear and the parking brake applied) for
a few minutes before turning
the engine
off. If you do get the overheat warning, see “Engine
Overheating” in the Index.
Parking on Hi//s
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. When parking uphill,
turn your wheels
away from the curb. When parking downhill,
turn your wheels into the
curb.
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-wheeldrive 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.

NOTICE:
Do not tow with sling-type equipment or the rear bumper
system will be damaged.
Use wheel lift or car-carrier equipment.
Additional ramping may be required for car-carrier equipment.
Use safety chains and wheel straps.
If your vehicle has the four-wheel drive option, a dolly MUST
be used under the front wheels when towing from the rear.
Engine Overheating
You will find a coolant temperature gage on your vehicle's instrument
panel.
If Steam Is Coming From Your Engine

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:
Give freezing protection down to -34°F (-37 “C).
Give boiling protection up to 262°F (128 “C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 6038-M,” or “GM Specification
6043-M’ with the 2.2L (LN2) Code 4 engine, which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to “GM
Specification 603%”’ or “GM Specification 6043-M” with the 2.2L
(LN2) Code 4 engine. 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.

your radiator pressure
cap, a
GM cap is
recommended. See
"Service Replacement
Part and Filter
Recommendations"
in
the Index.
Thermostat
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.
