How long should you keep the block
heater plugged in? The answer depends
on the weather, the kind
of oil you
have, and some other things. Instead of
trying to list everything here, we ask
that you contact an Oldsmobile dealer
in the area where you’ll be parking your
vehicle. The dealer can give you the best
advice for that particular area.
Shifting the Automatic
Transaxle
Your automatic transaxle may have a
shift lever located on the steering
column or on the console between the
seats. Both are shown above.
Maximum engine speed
is limited on
automatic transaxle vehicles when
you’re in
D (Drive) or N (Neutral), to
protect driveline components from
improper operation. There
are six shift positions, seven if you
have Overdrive. In this manual, these
are referred to by the commonly used
symbols in the right column below:

Climate Control
The air conditioner and heater work
best
if you keep your windows closed
while using them. Your vehicle also has
the flow-through ventilation system
described later in this section.
OFF: Press to turn the blower off.
Some air will still come from the outlets
at the floor. Press any function button
to turn the system
on.
Temperature Control Lever: This
lever changes the temperature of the air
coming through the system. The higher
the lever setting, the warmer the air.
3f: Selects the force of air you want.
Press
LO to lower the fan speed, HI to
raise
it.
Air Conditioning
On very hot days, open the windows
long enough to let hot inside air escape.
This reduces the time it tales for your
vehicle to cool down, which should help
fuel economy.
There are three air conditioning
settings:
MAX: Provides maximum cooling or
quick cool-down
on very hot days. This
setting also helps prevent outside odors
from entering your vehicle.
This setting recirculates much of the air
inside your vehicle, and it should not be
used for long periods because the air
may become too cold and
dry. This
setting is not recommended if an
occupant is smoking.
NORM: Use for normal cooling on hot
days. This setting brings in outside air,
cools it and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use on cool, but
sunny days. This setting brings in the
outside air, but directs it in two ways.
The cool air is directed to the upper
portion of your body through the
instrument panel outlets, but most
warmed air is directed through the
heater ducts and a little to the defrost
and side window vents. At times this
temperature difference may be more
apparent than others.

Heating and Venfilafion
When you don’t need to cool the outside
air, use these next settings.
You can
leave the air as it is or heat it.
The air conditioner compressor doesn’t
run in these settings. This reduces the
engine load, resulting in improved fuel
economy (gas mileage)
.
VENT: For mild outside temperatures,
when little heating or cooling is needed,
push
VENT. Air flow is through the
instrument panel outlets. Slide the
temperature control lever to a
comfortable level.
HEAT: When outside temperatures are
cold, push
HEAT. Slide the temper-
ature control lever to a comfortable
level. For maximum heating, slide it all
the way to the right.
This setting will send most of the heated
air through the ducts near the floor. The
rest will come out of the defroster vents
and side window defogger vents.
Defogging and Defrosting
There are two settings for clearing your
windows. For each setting, adjust the
temperature control
as desired. The air
conditioner compressor will run in
these settings to remove moisture from
the air when the temperature
is above
freezing.
tv th This setting allows half of
e air to flow to the floor
heater ducts, and half to
go to the windshield and
side window vents located
in the windshield pillars.
Use this setting to warm
passengers while keeping
the windshield clear. The
DEF setting directs 90% of
the air
through the defroster vents and the side
window vents, and
10% to the floor.

Directional Controls
When the following buttons are pressed,
an indicator light will glow above the
button.
BI-LEV (Bi-Level): Use on cool, but
sunny days. This setting brings in the
outside air, but directs it in two ways.
The cool air is directed to the upper
portion of your body through the
instrument panel outlets, but most
warmed air is directed through the
heater ducts and a little to the defrost
and side window vents. At times this
temperature difference may be more
apparent than others.
UPPER: Press to direct air flow
through the instrument panel outlets
only.
LOWER: Press to direct 90% of the air
flow through the heater ducts, and
10%
of the air flow through the windshield
defroster vents.
DEFOG: Press to direct half the air to
the windshield, and the other half
through the heater ducts.
DEF (Defrost): Press to direct 90% of
the air to the windshield and side
window vents, and
10% to the floor.
The fan will automatically go to high.
For a lower fan speed, press the fan
switch.
OFF: Press to turn off the system.
Some air will still come
from the outlets
at the floor.

Flow-Through Ventilation System
Your Oldsmobile'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. Ventilation Tips
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, set the blower fan to the
highest setting 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're Caught in a Blizzard
(CONT.)
Run your engine only as long as you
must. This saves fuel. When you run
the engine, male it go a little faster
than just idle. That is, push the
accelerator slightly. This
uses less fuel
for the heat that you get and it keeps
the battery charged. You will need a
well-charged battery to restart the
vehicle and possibly for signaling later
on with your headlights. Let the
heater run for a while.
Then, shut the engine
off and close
the window almost all the way to
preserve the heat. Start the engine
again and repeat this only when you
feel really uncomfortable from the
cold. But do it as little
as possible.
Preserve the fuel as long as you can.
To help keep warm, you can get out of
the vehicle and do some fairly
vigorous exercises every half-hour or
so until help comes.
If You're Stuck in Deep Snow
This manual explains how to get the
vehicle out of deep snow without
damaging it. See the

I A If vou don't use the correct "
, equipment and drive
properly, you can lose control when
you pull
a trailer. For example, if
the trailer is too heavy, the brakes
may not work well-or even at all.
You and your passengers could be
seriously injured. Pull a trailer
only
if you have followed all the steps in
this section.

Engine Overheating (CONTJ
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 get a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
198
If you get the overheat warning with no
sign of steam, try this for a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the
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 ab& 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.
f there's still no sign of steam, you can
dle the engine for two or three minutes
vhile you're parked, to see if the
varning stops.

Cooling System
When you decide it’s safe to lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan
If the coolant inside the coolant
recovery tank is boiling, don’t do
anything else until it cools down. The
coolant level should be at or above
the
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.
I
- 1
CAUTION I
Heater and radiator hoses,
and other engine parts, can
1;, ;cry 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
I
you drive the vehicle.
I
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
COLD, add a
50/50 mixture of clean
water (preferably distilled) and a proper
antifreeze at the coolant recovery
tank.
(See the Index under Engine Coolant
for more information abaut the proper
coolant
mix.)

3. After the engine cools, open the
coolant air bleed valve or valves.
3.1L V6 (VIN Code T or M): There
are two bleed valves. They are located
on the thermostat housing and the
thermostat bypass tube.
3.4L V6 (VIN Code X): There are
two bleed valves. They are located on
the thermostat housing and the
heater inlet pipe. 4. Fill the radiator with the proper mix,
up to the base of the filler neck.
If you see a stream of coolant coming
from
an air bleed valve, close the valve.
Otherwise, close the valve(s) after the
radiator is filled.
5. Rinse or wipe any spilled coolant
from the engine and compartment.
