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 TM antifreeze.

may fail a smog-check test. If this occurs, return to your
authorized Aurora retailer for diagnosis to determine the
cause of failure. In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may not be covered by your warranty.
Some Canadian gasolines contain an octane enhancing
additive called methlycyclopentadienyl manganese
tricarbonyl (MMT).
If such fuels are used, your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on.
If this occurs, return to your
authorized Aurora retailer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming in your engine and fuel system, allowing your
emission control system to function properly. Therefore,
you should not have to add anything to the fuel. In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available in your area to help clean the air. General
Motors recommends that you use these gasolines if they
comply with the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
Lf you plan on driving in another country outside the United
States or Canada, the proper fuel may
be hard to find.
Never use leaded gasoline or any other fuel not recommended
in the previous text on fuel. Costly repairs caused by use
of improper
fuel wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your

Engine Oil
OIL
If the CHECK OIL
LEVEL message or
the oil warning 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.
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.

When to Add Oil
If the oil is at or below the ADD line, then you’ll need to
add some oil. But you must use the right kind.
This part
explains what
kind of oil to use. For crankcase capacity,
see “Capacities and Specifications”
in the Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
Just fill it enough to put the level somewhere in the
proper operating range. Push the dipstick all the way
back in when you’re through.
What Kind of Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute
(API). Do not use any oil which
does not carry this Starburst symbol.
If you change your
own oil, be sure you
use
oil that has the
Starburst symbol on
the front of the oil
container. If you have
your oil changed for
you, be sure the oil put
into your engine is
American Petroleum
Institute certified for
gasoline engines.
You should also use the proper viscosity oil
for your
vehicle,
as shown in the following chart:

going to be colder than
60" F (1 6 O C) before your
next oil change. When it's very cold, you should use
SAE 5W-30. These numbers on an oil container show
its viscosity,
or thickness. Do not use other viscosity
oils, such as
SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines "Starburst" symbol. Failure to use the
recommended oil can result in engine damage
not covered by your warranty.
GM Goodwrench@ oil meets all the requirements for

When to Change Engine Oil

Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil
to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first. (See “Change Oil Message” in the Index.)
If
the CHANGE OIL NOW message appears in the Driver
Information Center, you should change your oil.
If none of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever occurs first. Driving a vehicle
with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
(See “Change Oil Message” in the Index.) Always reset
the engine oil life
to 100% after every oil change.
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.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level
is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90 OF (32 O C) or higher.
In hilly or mountainous terrain.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services” in the Index.
How to Check
Because this operation can be a little difficult, you
may choose to have this done at your Aurora retailer
Service Department.
If
you do it yourself, be sure to follow all the instructions
here, or
you could get a false reading on the dipstick.
I NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to
get an accurate reading
if you check your
transaxle fluid.

Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles (1 66 000 km),
whichever occurs first.
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.
A
50/50 mixture of water and the proper coolant for
your Aurora will:
0 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.
NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If
silicated coolant 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.
What to Use
Use a mixture of one-half cEean, water (preferably
distilled) and one-half
DEX-COOL TM (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. 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.
