Section ,I 3 Comfort Controls and Audio Systems
In this section you’ll find out how to operate the comfort
control and audio systems offered with your Pontiac. Be
sure
to read about the particular systems supplied with
your vehcle.
Comfort Controls
With this system, you can control the heating and
ventilation in your Pontiac.
If you have the air
conditioning option, you can also control cooling. Your
vehicle also has the flow-through ventilation
system described later in this section.
Fan Control Knob
FAN: Turn this knob to select the force of air
you want.
Temperature Control Knob
Turn the knob to change the temperature of the air
flowing from the heating system. Turn it to the right for
warmer air and
to the left for cooler air. The temperature
of the air cannot be less than the temperature of the
outside air.

Air Control Knob
OFF: The system is off.
3 VENE Air flows through the upper air vents.
12 BI-LEVEL: Air is directed through the upper air
vents
and the heater ducts.
12 HEATER: This setting directs most of the air
through the heater ducts and some of the air through the
windshield defroster vents.
9 BLEND: Air is directed through the windshield
defroster vents and
the heater ducts.
DEFROST: This setting directs most of the air
through
the windshield defroster vents and some of the
air through the heater ducts.
The air conditioning system uses the same controls as
the heating system, except that the air control knob has . .. 7 two extra settings, described below. _.
MAX: Provides maximum cooling or quick cool-down
on very hot days.
This setting recirculates most of the air
inside your vehicle. If it is used for long periods of time9
the air
may become dry. This setting directs air through
the upper air vents.
NC: Use for normal cooling on hot days. This setting
cools outside air and directs it through the upper air vents.

The air conditioner compressor operates in MAX, A/C,
BI-LEVEL, BLEND and DEFROST when the outside
temperature is above freezing. When the air conditioner
is on, you may sometimes notice slight changes
in your
vehicle’s engine speed and power. This is normal because
the system .is designed to cycle the compressor on and off
to keep
the desired cooling and help fuel economy.
Cooling
The air conditioner works best if you keep your
windows closed.
On very hot days, open the windows
just long enough for the hot air to escape.
1. Turn the air control knob to A/C for normal cooling.
2. Turn the temperature control knob to a

comfortable setting. During initial start-up
only, if your vehicle
is equipped
with an optional engine coolant heater, you can use it in
cold weather (around
+20 O F/-8 O C or lower) to improve
heater performance on start up. Because an engine
coolant heater warms the engine coolant, your vehicle’s
‘heating system can more efficiently provide heat for the
passenger area
of your vehicle. See “Engine Coolant
Heater” in the Index.
Bi-Level Heating
You may want to use bi-level heating on cool, but sunny
days. This setting directs cool air toward your body and
warmer air toward your feet.
1. Turn the air control knob to BI-LEVEL.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed.

The heater works best if you keep your windows closed
while using it.
1. Turn the air control knob to HEATER.

Pontiac's flow-through ventilation system
supplies outside air into the vehicle when it is moving.
Outside air will also enter the vehicle when the
blower
fan is running.
Ventilation Tips
0 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
fan control knob to the right for a few moments
before driving off. This helps clear the intake ducts
of snow and moisture, an'd 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.

If you drive regularly in steep country, or if you’re
planning
to visit there, here are some tips that can make
your trips safer and more enjoyable.
e Keep your vehicle in good shape. Check all fluid
levels and
also the brakes, tires, cooling system and
transmission. These parts
can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift
to a lower gear when you go
down a steep or long hill.
If you don’t shift down, your brakes could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going
down a hill.
You could crash. Shift down to let
your engine assist your brakes on a steep
downhill slope.
I
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have to
do all the work of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor
braking or even none going down a hill.
You could crash. Always have your engine running
and your vehicle
in gear when you go downhill.
Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transmission, and you can climb the hill better.
0 In hilly terrain, you may want to switch to the
PERFORMANCE mode for better performance.
Stay in your own lane when driving on two-lane
roads’in
hills or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you
stay in your own lane.

An electric fan under the hood can start up even
when the engine
is not running and can injure
you. Keep hands, clothing
and tools away from
any underhood electric fan,
If the coolant inside the coolant recovery tank is boiling,
don’t do anything
else until it cools down.
When it is cool, remove the coolant recovery tank cap
and
look at the dipstick.
The coolant level should be at FULL COLD. 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.

5-16
ProCarManuals.com

Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine if there is a leak.
If you run
the engine, it could lose all coolant. That could
cause
an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.

NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine fan is running. If the engine
is
overheating, the fan should be running. If it isn’t, your
vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD, add a 50/50 mixture of clean
water
(preferably distilled) and DEX-COOL TM
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant” in the Index for
more information.)
I A CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix
will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use a
50/50 mix of clean
water and
DEX-COOL TM antifreeze.
ProCarManuals.com

NOTICE:
.In cold weather, water can freeze and crack the
engine, radiator, heater core
and other parts.
Use the recommended coolant and the proper
coolant
mix.
- -
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn
if the engine parts are hot
enough. Don't
spill coolant on a hot engine.
When the coolant in the coolant recovery tank is at
FULL COLD, start your vehicle.
If the overheat warning continues, there's one more
thing you can try. You can add the proper coolant mix
directly to the radiator, but be sure the cooling system is
cool before you do it.
