cooling PONTIAC GRAND AM 1997 Owners Manual

Synchronization Your Keyless Entry System is equipped with a security
system that prevents anyone from recording and playing
back your signal. The transmitter does not send the same
signal twice to the receiver. The receiver will not
respond
to a signal that has been sent to it more
than once.
Trunk
To resynchronize your transmitter and receiver, follow
these directions:
1. Stand close to your vehicle.
2. Press and hold the LOCK and UNLOCK buttons on
the transmitter at the same time.
3. Hold the buttons for five seconds. In this time, the
doors should lock and unlock once. This confirms
the resynchronization. If the doors do not lock and
unlock, see your dealer for service.
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder.
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle.
You can’t see or smell
CO.
It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

Comfort Controls
With this system, you can control the ventilation and
heating
in your vehicle.
Your vehicle also has the flow-through ventilation
system described later in this section.
Climate Control System
Fan Knob
The left control knob sets the fan speed. To select the
force of air you want, turn the knob. The fan is always
running unless the mode control is moved to
OFF.
Temperature Knob
The center control knob regulates the temperature of the
air coming through the system.
Mode Knob
The right control knob changes the functions of your
system.
2 VENT Use when outside temperatures are mild,
and little heating or cooling is needed. Airflow is
through the instrument panel outlets. Set the center
control knob to the temperature desired.
9 BI-LEVEL: Use on cool, but sunny days. This
setting brings in the outside air, but directs
it in two
ways. Cooler air
is directed to the upper portion of your
body through the instrument panel outlets; slightly
warmer air is directed through the heater ducts and
defroster vents. At times, this temperature difference
may be more apparent than others.
3-2

Mode Knob
The right control knob changes the functions of your
system.
MAX: Use for maximum cooling. This setting
recirculates much of the air inside your vehicle. It
maximizes your air conditioner’s performance and your
vehicle’s fuel economy.
A/C: Use for normal cooling on hot days. This setting
cools outside air and directs it through the instrument
panel outlets.
9 BI-LEVEL: Use on cool, but sunny days. This
setting brings in the outside air, but directs it in two
ways. Cooler air is directed to the upper portion
of your
body through the instrument panel outlets, but slightly
warmer air is directed through the heater ducts and
defroster vents. At times, this temperature difference
may be more apparent than others.
2 VENT Use when outside temperatures are mild,
and little heating or cooling is needed. Airflow is
through the instrument panel outlets. Set the center
control knob to the temperature desired.
‘!A HEATER: This setting brings heated air through
the heater ducts, and some through the windshield
defroster vents.
If you have the optional engine coolant heater (engine
block heater) and use it during cold weather,
0°F
(- 18 O C) or lower, your heating system will more quickly
provide heat because the engine coolant is already
warmed. See “Engine Coolant Heater” in the Index.
9 BLEND: This setting divides airflow equally
between the heater ducts and the windshield defroster
vents.
DEFROST This setting directs air through the
windshield defroster vents located on top of the
instrument panel.
3-4

Air Conditioning Heating
Turning
the right control knob to HEATER and the
center control knob clockwise sends some heated air
through the heater ducts toward your feet, and some
through the defroster vents.
On very
hot days, open the windows long enough to let
hot, inside air escape. This reduces the time
it takes for
your vehicle to cool down, which should help fuel
economy.
For quick cool-down on very hot days, use MAX with
the temperature knob all the way in the blue area.
If the
setting is used for long periods of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use
NC with the
temperature knob in the blue area. The system will bring
in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough. You
can use
BI-LEVEL with the temperature knob in the
middle. The system will bring in outside air and direct
it
to your upper body, while sending slightly warmed air to
your lower body. You may notice this temperature
difference more at some times than at others. VENT
and HEATER are economical positions because
the air conditioner compressor doesn’t run in these
two settings. This reduces engine load, resulting in
improved fuel economy.
If either setting fails to keep
you comfortable, or causes your windows to fog up, turn
the right control knob to one of the air conditioning
positions, or to DEFROST.
If you have the optional engine coolant heater
(engine block heater) and use
it during cold weather,
0 “F (- 18 O C) or lower, your heating system will more
quickly provide heat because the engine coolant is
already warmed. See “Engine Coolant Heater” in
the Index.
3-5

Ventilation System
Use when outside temperatures are mild, and little
heating or cooling
is needed. Turn the right knob to
VENT. Airflow is directed through the instrument panel
outlets. Set the center knob to the temperature desired.
Your 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 heater or the air
conditioning fan is running.
Adjust the direction
of
airflow by moving the
louvered vents.
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.
When you enter a vehicle in cold weather, turn the
fan control knob to the highest position for a few
moments before driving
off. This helps clear the
intake ducts
of snow and moisture, and reduces the
chance
of fogging the inside of your windows.
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.
0 Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. 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.
~ A CAUTION:
I
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.
A CAUTION:
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. Drive in the highest
gear possible.
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.
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.

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 a gear for a manual transaxle.
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 to PARK
(P), or REVERSE (R)
for a manual transaxle.
5. Release the regular brakes.
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;
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 of the chocks.
4. Stop and have someone pick up and 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 transaxle fluid (don’t overfill),
engine oil, belt, 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.

/II CAUTION:
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 surge tank is boiling,
don’t do anything else until it cools down.
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.
5-17

/11 CAUTION:
I
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don% 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.
I 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
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at or above
FULL COLD, add a 50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
coolant at the coolant surge tank, but be sure the cooling
system, including the coolant surge tank pressure cap,
is
cool before you do it. (See “Engine Coolant” in the
Index for more information.)
A CAUTION:
Steam and scalding lipuids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and
if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out
at high speed. Never turn the cap
when the cooling system, including the coolant
surge tank pressure cap, is hot. Wait for the
cooling system and coolant surge tank pressure
cap to cool if you ever have to turn the
pressure cap.
5-18

1 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@ coolant.
NOTICE:
r
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts,
So
use the recommended coolant. 1
