1997 BUICK PARK AVENUE cooling

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:
0 Make sure all windows are shut.
0 Tbrn the fan on your heating or cooling
system to its highest speed with the setting
on any airflow selection except RECIRC.
That will force outside
air into your vehicle.
See “Comfort Controls’’ in the Index.
0 If you have air outlets on or under the
instrument panel, open them all the way.
See “Engine Exhaust’’ in the Index.
Theft
Vehicle theft is big business, especially in some cities.
Although your Buick has a number
of theft-deterrent
features, we know that nothing
we put on it can make it
impossible to steal. However, there are ways you can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves
-- so
don’t do it.
With the ignition
off and the driver’s door open, you’ll
hear a chime reminding you to remove your key from
the ignition and take it with you. Always do this. Your
ignition and transaxle will be locked. And remember to
lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out
of sight.
Put them in a storage area, or take them with you.

Comfort Controls
This section tells you how to operate your comfort
controls. Your comfort control system uses
ozone-friendly
R- 134a refrigerant.
With these systems, you can control the heating, cooling
and ventilation in your Buick. Your vehicle also has a
flow-through ventilation system described later in
this section.
Personal Choice Comfort Controls
(If Equipped)
This feature allows two different drivers to store and
recall their own climate control settings for temperature, air delivery mode, fan and passenger climate control
(ordoff) status. The Personal Choice settings recalled
are determined by the transmitter used to enter the
vehicle. After the
UNLOCK button of a remote keyless
entry transmitter is pressed, and the ignition is in
RUN,
the climate control will adjust to the last settings of the
identified driver. The settings can also be changed by
briefly pressing one of the
MEMORY seat switches
located on the driver’s door panel. When adjustments
are made, the new settings
are automatically saved for
the driver.
Dual Automatic ComforTemp Climate Control
Your Buick has the dual automatic comfortemp climate
control system. The following information tells you how
it works.
You will hear a beep each time a button is pushed and a
small light on the button will indicate which buttons are
active. The lights are on all buttons except
TEMP, FAN
and
AIR FLOW. The display will show fan speed,
comfort level setting and airflow direction for a few seconds whenever any button, except for the rear
defog, is pushed, and then it will display the outside
temperature. The outside temperature reading is most
accurate when the vehicle is moving.
During stops, when driving slow, or when the engine is
first started after a short trip, the outside temperature
reading can be affected by road or engine heat. In order
to ensure proper automatic climate control operation, the outside temperature display may not update as quickly
as expected.

RECIRC: When RECIRC is selected, the system will
limit the amount of outside air entering your vehicle.
This is helpful when you
are trying to cool the interior
of the vehicle quickly or limit the amount of outside air
entering your vehicle for some other reason. RECIRC
and AUTO may be selected at the same time. The
system will remain in RECIRC until the ignition is
turned
off. The system will return back to the previously
selected mode when the car is turned back on. RECIRC
can be selected in all manual airflow modes except
FRONT defrost. RECIRC cannot be selected with the
VENT button.
FRONT This selection is used to defrost the
windshield by directing the airflow toward the windshield.
If FRONT is selected while in the AUTO mode, the fan
speed and the
air temperature from the front defroster will
vary.
If a manual fan speed setting is selected, the fan
speed will remain
at that selection until another fan speed
selection is made or the AUTO mode is selected. To turn
off FRONT, press the AUTO or AIR FLOW button.
FRONT defrost will work better if any
ice or snow is
cleared from the hood and the air inlet area between the
base of the windshield and the hood.
Air Conditioning
On 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. Then keep your windows closed
for the air conditioner to work its best.
On very hot days, the system will automatically enter
the RECIRC mode and the temperature door will be
positioned at the full cold position for maximum
cooling. If the system is not in the AUTO mode,
RECIRC should be selected to provide maximum
cooling.
You can choose the extreme comfort setting of
60°F (16"C), but the system will not cool any faster
by choosing the extreme comfort setting.
Heating
Press AUTO and adjust the temperature by pressing the
TEMP up or down arrow. You may also adjust the dual
automatic comfortemp system manually by pressing the
AIR FLOW button until FLOOR appears. Again, adjust
the temperature by pressing the TEMP up or down arrow.
Outside air will be brought in and sent through the
floor outlets. The heater works best if you keep your
windows closed.

Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle. Air will
flow through any of the
outlets depending on outside temperatures and comfort
level settings.
Your vehicle’s flow-through ventilation system supplies
outside air into the vehicle when it’s moving. When the
vehicle is not moving, you can get outside air to flow
through by selecting any air choice (except the rear
window defogger) and
any €an speed.
Adjust the direction
of
airflow by moving the
louvered vents. You have rear passenger comfortemp outlets that
you
can use to adjust the direction of the airflow to the rear
seating area. The temperature is controlled
by the front
passenger setting.

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.
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.
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.
-_ 1
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.
0 Know how to go uphill. Drive in the highest
gear possible.
0 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.

Driving On Grades
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 to
THIRD (3) and
reduce your speed to around
45 mph (70 km/h) to reduce
the possibility of engine and transaxle overheating.
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
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).
5. Release the regular brakes.
PARK (P) yet.
When You Are Ready to Leave After
Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
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, 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.

The coolant level should be at or above the FULL
COLD mark.
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.
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.
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 fans are running. If the engine
is overheating, both fans should be running.
If they
aren’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
DEX-COOL@ (silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant” in the Index for
more information.)
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.
I 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.
