This is an estimate of the oil’s remaining useful life.
It
will show 100% when the system is reset after an
oil change. It will alert you to change your oil on a
schedule consistent with your driving conditions. When the remaining
oil life or transaxle fluid
life is low,
the system
will alert you with a message:
CHANGE OIL

When the oil or transaxle fluid life is down to zero, you
will receive the message:
CHANGE OIL NOW or
CHANGE TRNS FLUID
NOW
To reset the OIL LIFE reminder after an oil change or the
TRNS FLUID LIFE reminder after a transaxle fluid change:
1. With the ignition on, press the ENG button so the
OIL LIFE percentage or the TRNS LIFE percentage
is displayed.
2. Press RESET and hold for five seconds. The word
RESET will appear, then OIL LIFE
100% or TRNS

Remember, you must reset the OIL LIFE or TRNS
FLUID yourself after each oil or transaxle fluid change.
It will not reset itself. Also, be careful not to reset the
OIL LIFE or TRNS FLUID accidentally at any time
other than when the oil or transaxle fluid has just been
changed. It can’t be reset accurately until the next oil or
transaxle fluid change.
The Driver Information Center does not replace the need
to maintain your vehicle as recommended in the
Maintenance Schedule in this manual. Also, the oil
change reminder will not detect dusty conditions or
engine malfunctions that may affect the oil. If you drive
in dusty areas, change your oil after every
3,000 miles
(5 000 km) or three months, whichever comes first,
unless the
DIC instructs you to do so sooner. Also, the
oil change reminder does not measure how much oil you
have in your engine.
So, be sure to check your oil level
often.. See “Engine Oil” in the Index.
Check Oil Level Warning
When CHECK OIL LEVEL appears, it indicates that the
engine oil level is
1 to 1 1/2 quarts (0.9 L to 1.4 L) low.
The message will appear only if the engine is running
and it’s been at least eight minutes since the engine was
last running. If the message appears, check the oil
dipstick level. If
it reads low, your oil level should be
brought up to the proper level (see “Engine Oil” in the\

Index). After bringing the oil to the proper level, the
ignition must be
off for eight minutes to allow the
majority of oil to drain into the oil pan.

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.

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.
