Towing Your Vehicle
Try to have an Oldsmobile retailer or a professional
towing service tow your Aurora. See “Roadside
Assistance” in the Index.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero-skirting, or special tires and wheels, these
instructions and illustrations may not be correct.
Before you
do anything, turn on the hazard
warning flashers.
When you call, tell the towing service:
0 That your vehicle can only be towed from the front
with sling-type equipment.
0 That your vehicle has front-wheel drive.
0 The make, model and year of your vehicle.
0 Whether you can still move the shift lever.
0 If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains detailed towing
instructions and illustrations. The operator may want
to
see them.

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.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
Tow a trailer.
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.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 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.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if
the warning stops. But then, if you still have the
warning,
turn 0fSth.e engine and get everyone out
of the vehicle until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously in
this section.
You may decide not to lift the hood but to eet service
help right away.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or THIRD (3).

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:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
~~ ~ ~
You
can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.

Ckanging a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
Changing
a tire can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people. You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won't move,
you can put blocks
at the front and rear of the
tire farthest
away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end.

OIL
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
-cloth, ,then push it back in all the way. Remove it again,
keeping the tip down, and check the level. If the CHECK OIL LEVEL
message or the
oil warnkg
light on the instrument
panel comes on, it means
you need to check your
engine oil level right away.
For more information, see “Check
Oil Level Message”
or “Oil Pressure Warning Light” in the Index. You
should check your engine
oil level regularly; this is an
added reminder.
It’s a good idea to check your engine
oil every time you
get
fuel. In order to get an accurate reading, the oil must
be warm
and the vehicle must be on level ground.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstick
might not show the actual level.

What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your
skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If
you have a problem properly disposing of your used oil,
ask your retailer, a service station or a local recycling
center for help.
Air Cleaner
To Check or Replace the Air Filter:
1. Remove hose from resonator channel.

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.
3. After adding fluid, recheck the fluid level as
described under “How to Check.”
4. When the correct fluid level is obtained, push the
dipstick back
in all the way.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant
is designed
to remain
in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX-COOL@ extended life coolant.
Lx
It doesn’t take much fluid, generally less than one pint The following explains
Your cooling system and how to
(0.5 L). Don’t overjill. add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating” in
the Index.
NOTICE: A 50/50 mixture of water and DEX-COOL’
coolant will:
We recommend you use only fluid labeled
DEXRON’III, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than
DEXRON@III
is not covered by your new vehicle warranty.
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature,
Let the warning lights and gages work as
they should.

What to Use I
NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@ is added to
the system, premature engine, heater core or
radiator corrosion may result.
In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs
first. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum
parts. If you use this mixture,
you don’t need to add anything else. A special procedure
is required for adding sealer; see the Aurora Service
Manual.
(To order a service manual, see “Service
Publications’’ in the Index.)

There are only two reasons why the brake fluid level in the
reservoir might go down. The first
is that the brake fluid
goes down to
an acceptable level during normal brake
lining wear. When new linings are put in, the fluid level
goes back up. The other reason is that fluid is leaking out
of the brake system. If it is, you should have your brake
system fixed, since a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top ofi?’ your brake fluid.
Adding brake fluid won’t correct a leak.
If you add fluid
when your linings are worn, then you’ll have too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done on
the brake hydraulic system. When
your brake fluid falls to a low level, your brake
warning light will come on.
A chime will sound if you
try
to drive with this warning light on. See “Brake
System Warning Light”
in the Index.
What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 1 I @ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing
it. This will help keep
dirt from entering
the reservoir.
If you have too much brake fluid, it can spill on the
engine. The fluid will burn
if the engine is hot
enough.
You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work is done on the brake hydraulic system. With the wronb -4nd
of fluid in your
brake
system, your brakes may not work well, or they
may not even work at all. This could cause
a
crash. Always use the proper brake fluid.

NOTICE:
Using the wrong fluid can badly damage
brake system parts. For example, just
a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index.
Brake Wear
Your Aurora has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when
the brake pads are worn
and new pads are needed. The sound may come and go or
be heard all the time your vehicle is moving (except when
you are pushing on the brake pedal fiily).
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
