Engine Overheating
You will find a coolant temperature gage on your
Aurora’s instrunlent panel. Your information center
will
also display messages about engine overheating. See
“Coolant Temperature Gage“
in the Index.
Overheated Engine Protection Operating Mode
Should a low coolant condition exist and the message
HOT STOP ENGINE display, an overheat protection
mode which alternates firing groups of four cylinders
helps prevent engine damage. This operating mode
allows
YOLIP vehicle to be driven to a safe place in an
emergency; you may drive
up to 50 miles (80 km).
Towing a trailer in the overheat protection lnode should
be avoided.
NOTICE:
After driving in the “Overheated Engine
Protection Operating Mode,” to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be
severely degraded. Change the oil and reset the
oil life indicator. See “Engine Oil, When to
Change” in the Index.

Fuels in Foreign Countries
If you plan on driving in another country outside the
U.S. or Canada, unleaded fuel may be hard to find. Do
not use leaded gasoline. If you use even one tankful,
your emission controls won't work well or at
all. With
continuous use, spark
plugs can get fouled, the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle's oxygen sensor
will be damaged.
All of that means costly repairs that 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
LIS where you're going and give your
Vehicle Identification Number
(VIN).

Engine Oil
If the CHECK 01L 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
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.

To Check 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 of the proper quality for your vehicle can be
identified by looking for the ‘bStarburst” symbol. The
“Starburst” symbol indicates that the oil has been
certified by the American Petroleum Institute (API), and
is preferred for use in your gasoline engine.
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:
RECOMMENDED SAE VlSCOSlTV GRADE ENGINE OILS
FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
SAE VISCOSITY GRADE OIL
FOR THE EXPECTED TEMPERATURE RANGE.
HOT
WEATHER
LOOK
FOR MIS
SYMBOL
I-.
SAE lunl-30 PREFERRED
DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
I
6-12
ProCarManuals.com

As shown in the chart, SAE 10W-30 is best for your
vehicle. However,
you can use SAE SW-30 if it’s going
to be colder than
60°F (16°C) before your next oil
change. When it‘s very cold. you should use
SAE
SW-30. These numbers on an oil container show its
viscosity,
or thickness. Do not use other viscosity oils,
such
X SAE 2OW-SO.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to use the proper oil
can result in engine damage not covered by your
warranty.
GM Goodwrench@ oil (in Canada, GM Engine Oil)
meets all the requirements for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your Aurora retailer is
ready
to advise if you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
0 Most trips are less than 5 to I0 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.
0 You frequently tow a trailer or use a carrier on top of
your vehicle.
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 comes 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 SO0 km) or 12 months -- whichever
colnes first. (See “Change Oil Message’‘
in the Index.)
Always reset the engine oil life to 100% after every oil
change.

Engine Coolant Heater
An engine coolant heater can be a big help if you have
to park outside
in very cold weather, 0°F (- 18°C) or
colder.
If your vehicle has this option, see “Engine
Coolant Heater”
in the Index.
Air Cleaner
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.
To Check or Replace the Air Filter
1. Remove hose (A) from resonator channel.
2. Release tension of the wing screw clamp (B) on the
air intake duct where
it attaches to the air cleaner
cover near the top of
the engine. Just turn the wing
screw counterclockwise, then detach the duct from
the air cleaner cover.
3. Push the duct and resonator assembly (C) rearward
and up, and hold out of the way.

Refer to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services” in the Index.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
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. Refer to the
Maintenance Schedule to determine when
to change
your fluid. 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 Retail Facility
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.
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.
