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 overload, damaging the lighter and the heating element.
The ashtray must be completely pulled out
to open position
before the ashtray
cover opens and
smoking material can
be deposited.
Don’t put papers and other things that bum into your ashtray.
If you do,
cigarettes or other smoking materials could set them on fire causing
damage.
To remove the ashtray, lift the release tab as high as possib\
le, then remove
the tray.

If your vehicle has
four-wheel anti-lock
brakes, it will have
this yellow light.
3
With anti-lock, this light will go on when you start your engine and may
stay on for several seconds. That’s normal. If the light doesn’t come \
on,
have it fixed
so it will be ready to warn you if there is a problem.
If the light stays on, or comes on when you’re driving, your vehic\
le needs
service.
If the regular brake system warning light isn’t on, you still \
have
brakes, but you don’t have anti-lock brakes.
If the regular brake system
warning light is also on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System Warning Light”
earlier in this part.
Engine Coolant Temperature Gage
I 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 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.

come out of the heater outlet whenever the vehicle is moving forward.
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.
BI-LEV: Outside air comes in through the heater floor vents and the
instrument panel vents. This setting is useful in cool weather \
with bright sunlight.
HEAT Heated air comes out through the heater floor vents and windsh\
ield
defroster vents. This setting is useful for cold weather.
BLEND: Airflow is divided equally between the heater floor vent and t\
he
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.
Heater/Air Conditioning Controls
If your vehicle has air
conditioning, your
heatedair conditioning
controls will look like
this.
Before using your vehicle's air conditioning, open the windows \
to clear the vehicle
of hot air.
The switch on the righthand side changes the fan speed. To increase the fan
speed, push the switch upward toward
HI. To decrease the fan speed, push
the switch downward toward
LO .
The upper knob changes the air temperature. Turn the knob righ\
t (clockwise)
for warmer air. Turn the knob left (counterclockwise) for coo\
ler air.
The lower knob changes the heater function and determines which out\
lets
the air will flow through (instrument panel, defroster, heater, etc\
.).

If you use the optional engine coolant heater before starting your engine,
your heating system will produce warmer air faster, to heat th\
e passenger
compartment in cold weather. See “Engine Coolant Heater” in the Index.
Audio Systems
Your Delco@ audio system has been designed to operate easily and give
years of listening pleasure. But you will get the most enjoyment out of it if
you acquaint yourself with
it first. Find out what your Delco’ system can
do and how to operate
all its controls, to be sure you’re getting the most out
of the advanced engineering that went into it.
Be aware that hearing damage from loud noise is almost undetectable until
it is too late. Your hearing can adapt to higher volumes of sound. Sound that
seems normal can be loud and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe sound le\
vel before your
hearing adapts to it.

Reduce speed and shift to a lower gear before you start dawn 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.
If you have an automatic transmission, you should use “D” when towing a
trailer. Operating your vehicle
in “D” when towing a trailer will minimize
heat buildup and extend the life of your transmission.
Or, if you have a
rrianual transmission with fifth gear, it’s better not to use fifth gear, just
drive in fourth gear (or, as
you need to, a lower gear).
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 “P” (Park) yet, or into
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
gear
for
a manual transmission.
chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking brake, and \
then
shift into
“P” (Park), or “R” (Reverse) 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 “N” (Neutral).
6. Release the parking brakes,

You will find a coolant temperature gage on your vehicle’s instr\
ument
panel.
If Steam Is Coming From Your Engine
NOTICE:
If your engine catches fire because you keep driving with no
coolant, your vehicle cdh be badly damaged. The costly repairs
would not be covered by your warranty.

Downloaded from www.Manualslib.com manuals search engine If the differential is at operating temperature (w,arm), add enou\
gh lubricant
to raise the level to the bottom of the filler plug hole.
If the differential is cold, add enough lubricant to raise the level to 1/2 inch
(12
mm) below the filler plug hole.
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 -20 “F (-29” C), or -34°F (-37 “C) in
Canada and for vehicles with the cold climate option.
e Give boiling protection up to 258°F (125°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 mi,xture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 603%” or “GM Specification
6043-M ”for 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 ”for the 2.2L (LN2)
Code 4 engine with a complete coolant flush and refill.
If you use this
mixture, you don’t need to add anything else.

Radiator Pressure Cap
I 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.
When you replace
your radiator pressure cap, a
GM cap is
recommended. See
“Service Replacement
Part and Filter
Recommendations” in
the Index.
