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.

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 can not be less than
the temperature of the outside air.

During initial start-up only, if your
vehicle is eduipped with an optional
engine coolant heater, you can
use i't in
cold weather (around
+20°F/-8" C or
lower) to heat the passenger areq better
than without it. 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.

Air Conditioner Controls (OPTIoN)
The air conditioning system uses the same
controls
as the heating system, except that
the air control knob has two extra
settings, described below. For
an
explanation of all the controls, see
“Heater Controls” earlier in this part.
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 time, the air may become
dry. This
setting directs air through the upper air
vents.

A/C: Use for normal cooling on hot days
This setting cools outside air and directs
through the upper air vents.
The air conditioner comtxessor oDerates
in
“MAX,” “NC” and ii VJ , ,% and
9 when the outside temperature is
a6&e 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 desirec
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.

normal cooling. For faster cooling
move the knob to
‘“AX.”

Hill and Mountain
Roads
Driving on steep hills or mountains is
different from driving in flat or rolling
terrain. 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.
0 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.
0 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. 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.
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
you? own
lane.
As you go over the top of a hill, be
alert. There could be something in
your lane, like a stalled car or’an
accident.
You may see highway signs on
mountains that warn of special
problems. Examples are long grades,
passing or no-passing zones, a’ falling
rocks area, or winding roads. Be alert
to these and take appropriate action.

When You Are Ready to Leave after
Parking on a
Hill
1. Apply your regular brakes and hold
the pedal down while you:
0 Start your engine;
0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.

3. Drive slowly until the trailer is clear

store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often
when you're pulling a trailer. See the
Maintenance Schedule for more on this.
Things that are especially important in
trailer operation are automatic
transmission fluid (don't overfill), engine
oil, axle lubricant, belts, cooling system,
and brake adjustment. Each of these
is
covered in this manual, and the Index will
help you find them quickly. If you're
trailering, it's a good idea to review these
sections before you start your trip.
Check periodically to see that all hitch
nuts and bolts .are tight.

Problems on the Road
If your engine catches fire because
you keep driving with no coolant,
your vehicle can be badly darhaged.
The costly repairs would not be
covered by your warranty.
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 gel
a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer. If you
get the overheat warning with
no
sign of steam, try this for a minute or so:
1. If you have an air conditioner, turn it
2. Turn on your heater to full hot at the
off.
highest
fan speed and
open the
window as necessary.
3. Try to keep your engine under load
(in a drive gear where the engine runs
slower).
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,
you can
idle the engine for two or three minutes
while you’re parked, to see if the warning
stops. But then, if you still have the
warning, TURN
OFF THE 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.
Cooling System
When you decide it’s safe to lift the hood,
here’s what you’ll see on the V6 engine:
1. Coolant recovery tank
2. Radiator pressure cap
3. Electric engine fan
. . .I62
ProCarManuals.com

On the V8 engine you’ll see this:
1. Coolant recovery tank
2. Radiator pressure cap
3. Electric engine fans
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
or above
“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.
NOTICE:
Engine damage from running your
engine without coolant isn’t covered
by your warranty.
If there seems to be no leak, 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 or above the
“FULL COLD’ mark, 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:
I
In cold weather, water can freeze
and crack the engine, radiator,
heater core and other parts. Use the
recommended coolant. When the coolant
in the coolant recovery
tank is at or above the “FULL COLD’
mark, 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.

How to Add Coolant to the Radiator

I. You can remove the radiator pressure
cap when the cooling system,
including the radiator pressure cap
and upper radiator hose, is no longer
hot. Turn the pressure cap slowly to
the left until it first stops. (Don't pres:
down while turning the pressure cap.)
If you hear a hiss, wait for that to stor
A hiss means there is still some
pressure left.
2. Then keep turning the pressure cap,
but
now push down as you tum it.
Remove the pressure cap.
