running.
The reading will change as the rate of
:barge changes (with the engine speed,
?tc.), but readings between the red
warning zones indicate the normal
3perating range. Readings in either red
zone indicate a possible problem with
your charging system. Have your
Oldsmobile serviced immediately.
When the engine is not running but the
ignition
is on (in the Run position), the
display measures the voltage output of

Brake System Warning Light
Your Oldsmobile’s hydraulic brake
system is divided into two parts.
If one
part isn’t working, the other part can
still work and stop you. For good
braking, though, you need both parts
working well.
If the warning light comes on, there
could be a brake problem. Have your
brake system inspected right away.
This light should come on as you start
the vehicle. If it doesn’t come on then,
have it fixed
so it will be ready to warn
you if there’s a problem.
If the light comes on while you are
driving, pull off the road and stop
carefully.
You may notice that the pedal
is harder to push.

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.

Air Conditioner

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
A/C along with UPPER.

Towing from fhe Rear-Vehicle
HOOk-Up
Before hooking up to a tow truck, be
sure to read all the information
on
Towing Your Vehicle earlier in this
section.
1. Attach T-hook chains on both sides
in the slotted holes in the frame rails
just ahead
of the rear wheels.
I
2. Position the lower sling crossbar
directly under the rear bumper. No
4x4 wood beam is needed.
3. Attach a separate safety chain around
the end of each axle inboard
of the
spring.
4. Be certain your vehicle is towed no
faster than
35 rnph (56 ltm/h) and no
farther than
50 miles (80 ltm) to
avoid damage to your transaxle.
Engine Overheating
You will find a coolant temperature
gage on your Oldsmobile's instrument
panel. See the

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.

Engine Coolant
The following explains your cooling
system and how to add coolant when it
is
low. If you have a problem with
engine overheating, see
Engine
Overheating
in the Index.
The proper coolant for your Oldsmobile
will:
Give freezing protection down to-34”F
Give boiling protection up to 262°F
Protect against rust and corrosion.
Help keep the proper engine

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.
If you use this
mixture,
you don’t need to add anything

To Add Coolant
If you need more coolant, add the proper
mix
at the coolant recovery tank.
Add coolant mix at the recovery tank,
but be careful not to spill it.
Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi (105
kPa) pressure-type cap and must be
tightly installed to prevent coolant
loss and possible engine damage
from overheating. Be sure the
arrows on the cap line up with the
overflow tube on the radiator filler
neck.
When you replace your radiator
pressure cap, an AC8 cap is
recommended.
Thermostat
Engine coolant temperature is
controlled by a thermostat in the engine
coolant system. The thermostat stops
the flow of coolant through the radiator
until the coolant reaches a preset
temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
Power Steering Fluid
How To Check Power Steering
Fluid
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
When the engine compartment is hot,
the level should be at the
H (Hot)
mark.
When the engine compartment is
cool, the level should be at the
C
(Cold) mark.

Explanation of Scheduled
Maintenance Services
Following are explanations of the
services listed in Schedule I and
Schedule 11.
The proper fluids and lubricants to use
are listed in Section D. Make sure
whoever services your vehicle uses
these. All parts should be replaced and
all necessary repairs done before you or
anyone else drives the vehicle.
ITEM
NO. SERVICE
1. Engine Oil and Filter Change* -
Always use SH or SG Energy
Conserving
I1 oils of proper viscosity.
The
“SH” or “SG” designation may
be shown alone
or in combination
with others, such as “SH/CD,”
“SH,
SG, CD,” “SG/CD,” etc. To
determine the preferred viscosity for
your vehicle’s engine (e.g.,
SAE 5W-
30 or SAE 10W-30), see
Engine Oil
in the Index.
2. Chassis Lubrication - Lubricate
suspension and steering linkage.
Lubricate the transaxle shift linkage,
and parking brake cable guides,
underbody contact points and
linkage.
3. Tire and Wheel Rotation and
Inspection
- For proper wear and
maximum tire life, rotate your tires
following the instructions in this
manual. See
Tires, Inspection E.
Rotation in the Index. Check the
tires for uneven wear
or damage. If
you see irregular or premature wear,
check the wheel alignment. Check for
damaged wheels also.
Engine Accessory Drive Inspection
- Inspect the drive belt for cracks,
fraying, wear and proper tension.
Replace as needed.
I
Cooling System Servicee - Drain,
flush and refill the system with new
or approved recycled coolant
conforming to GM Specification
I
1825M. Keep coolant at the proper 1
mixture as specified. See Coolant in
the
Index. This provides proper
freeze and boil protection, corrosion

inhibitor level and maintains proper ’
engine operating temperature.
Inspect hoses
and replace if they are
cracked, swollen or deteriorated.
Tighten screw-type hose clamps.
Clean the outside of the radiator and
air conditioning condenser. Wash tht
pressure cap and neck.
To help ensure proper operation, we
recommend
a pressure test of both the
cooling system and the pressure cap.
