I Climate Control System
Your vehicle’s heater and air
conditioner work best if you keep your
windows closed. Your vehicle also has
flow-through ventilation, described late]
in this section, to bring outside air into
your vehicle.
If you have the optional engine coolant
heater and use it during cold weather,
0°F (-18°C) or lower, your heating
system will more quicldy provide heat
because the engine coolant is already
warmed. See the
Index under Engine
Coolant Heater.

system on.

glow).
Each time you turn on the ignition, the
air conditioner will default to the setting
you had selected before last turning off
the ignition.
When the air conditioner compressor is
on, you may sometimes notice slight
changes in your vehicle’s engine
performance and power. This is normal, because
the system is designed to help
fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture
from the air,
so you may sometimes
notice water dripping from under your
vehicle when it
is idling or after it has
been turned off. This is normal.
On very hot days, your vehicle will cool
down more quickly and economically if
you open the windows long enough to
let hot inside air escape. For all settings,
adjust the temperature control lever and
fan speed as desired.
Directional Controls
RECIRC (Recirculate): Press to get
maximum cooling or quick cool-down
on very hot days. This setting
recirculates much of the air inside your
vehicle. It should not be used for long
periods of time because the air may
become too cold and dry.
Slide the temperature control lever
down to the coolest setting and adjust
the fan speed as desired.
UPPER: For normal cooling on hot
days, press

There is something about an easy

along with the hum
of the tires on the
road, the drone

rush
of the wind against the vehicle that
can make you sleepy. Don’t let it
happen to you!
If it does, your vehicle
can leave the road in
less than a

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 countly,
or if you’re planning to visit there, here
are some tips that can make your trips
safer and more enjoyable.
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.

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
P (Park) yet.
2. Have someone place choclts under
the trailer wheels.
3. When the wheel chocks are in place,
release the regular brakes until the
chocks absorb the load.
apply your parking brake, and then
shift to
P (Park).
4. Reapply the regular brakes. Then
5. Release the regular brakes.
When You Are Ready to Leave
Affer Parking on a Hill
1. Apply your regular brakes and hold
the pedal down while
you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
4. Stop and have someone pick up and
of
the chocks.
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 quicltly. 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.

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, or fans if you
have the
3800 V6 engine.
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
FULL HOT 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.
ProCarManuals.com

When the coolant in the coolant
recovery tank is
at or above the FULL
HOT 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.
Yow 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 press down
while turning the pressure cap.)

How to Add Fluid
Refer to the Maintenance Schedule to
determine what kind of transaxle fluid
to use. See
Recommended Fluids and
Lubricants
in the Index.
If the fluid level is low, add only enough
of the proper fluid to bring the level into
the cross-hatched area
on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel: add
enough fluid at the dipstick hole to
bring it to the proper level.
It doesn’t take much fluid, generally less
than a pint
(OSL). Don’t overfill. We
recommend you use only fluid labeled
DEXRONo-I11 or DEXRON@-IIE,
because fluids with that label are made
especially for your automatic transaxle.
Damage caused by fluid other than
DEXRONo-I11 or DEXRONB-IIE is not
covered by your new vehicle warranty.
After adding fluid, recheck the fluid
level as described under
How to
Check.

the way.

system and how to add coolant when it
is

engine overheating, see
Engine

in the Index.
The proper coolant for your Oldsmobile
will:

Give boiling protection up to 262°F

What to Use
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets
“GM Specification
1825-M:” which won’t damage
aluminum parts.
You can also use a
recycled coolant conforming to
GM
Specification 1825-M with a complete
coolant flush and refill.

have been approved for use on General
~ Motors vehicles. All passenger type
(P Metric) tires must conform to
Federal safety requirements in addition
to these grades.
Wheel Alignment and Tire
Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to have
your wheels aligned again. However,
if
you notice unusual tire wear or your
vehicle pulling one way or the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels
may need
to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked
or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced.
If
the wheel leala air, replace it (except
some aluminum wheels, which can
sometimes be repaired). See your Oldsmobile dealer
if any of these
conditions exist.
Your dealer will know the kind of wheel
you need.
Each new wheel should have the same
load carrying capacity, diameter, width,
offset, and be mounted the same way as
the one it replaces.
If you need to replace any of your
wheels, wheel bolts, or wheel nuts,
replace them only with new GM
original equipment parts. This way, you
will be sure to have the right wheel,
wheel bolts, and wheel nuts for your
Oldsmobile model.
NOTICE:
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer/odometer
calibration, headlight aim, bumper
height, vehicle ground clearance,
and tire or tire chain clearance to
the body and chassis.
