GM Oil Life System
: Press the SELECT button
until OIL LIFE appears in the display. The OIL LIFE
NORMAL display will show an estimate of the oil's
remaining useful life. When the oil life index is less than
10%, an ENGINE OIL CHANGE SOON message will
be displayed and the oil life display will show OIL LIFE
CHANGE. When you have the oil changed according to
the maintenance schedule, you will have to reset the Oil
Life System. To reset the Oil Life System, see ªOil Life
Systemº in the Index. Also, see ªEngine Oil, When to
Changeº and ªMaintenance Scheduleº in the Index.
Tire Pressure Status: Press the SELECT button until
TIRE PRESSURE appears in the display. TIRE
PRESSURE NORMAL is displayed when the Check
Tire Pressure System believes your vehicle's tire
pressures are normal. If a potential problem is detected,
the display will show CHECK TIRE PRESSURE and
the tire pressure status will show TIRE PRESSURE
LOW. If you see the CHECK TIRE PRESSURE
message, you should stop as soon as you can and check
all your tires for damage. (If a tire is flat, see ªIf a Tire
Goes Flatº in the Index.) Also check the tire pressure in
all four tires as soon as you can. See ªInflation
-- Tire
Pressureº and ªCheck Tire Pressure Systemº in
the Index.
DIC Warnings and Messages
Other messages or warnings may appear in the DIC display.
For Canadian drivers, in addition to the DIC message your

If none of them is true, use the long trip/highway
maintenance schedule. 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.
When to Change Engine Oil (Vehicles With
the GM Oil Life System
Option)
If so equipped, your vehicle has a computer that lets you
know when to change your engine oil. This is not based
on mileage, but on engine revolutions and engine
operating temperature. When the computer has calculated
that the oil needs changing, the GM Oil Life System

will indicate that a change is necessary. The mileage
between oil and filter changes will vary depending on how
you drive your vehicle
-- usually between 3,000 miles
(5 000 km) and 10,000 miles (16 000 km) since your last
oil and filter change. Under severe conditions, the system
may come on before 3,000 miles (5 000 km). Never drive
your vehicle more than 10,000 miles (16 000 km) or
12 months (whichever occurs first) without an oil change.
The system won't detect dust in the oil. So, if you drive
in a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner. Remember to
reset the Oil Life System whenever the oil is changed.How to Reset the Oil Life System (If Equipped)
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Oil Life
System, press and hold the RESET button for more than
five seconds while the OIL LIFE is being displayed on
the DIC. The oil life will change to 100%.
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 dealer, a service station or a local recycling
center for help.

6-48 Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See ªWhen It's Time for New Tiresº and
ªWheel Replacementº later in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See ªScheduled
Maintenance Servicesº in the Index for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.Don't include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire
-Loading
Information label. Reset the Check Tire Pressure
System. See ªCheck Tire Pressure Systemº in the Index.
Make certain that all wheel nuts are properly tightened.
See ªWheel Nut Torqueº in the Index.
CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later, if
you need to, to get all the rust or dirt off.
See ªChanging a Flat Tireº in the Index.

Footnotes

The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle's useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.* If your vehicle has a GM Oil Life System, the system
will show you when to change the oil
-- usually between
3,000 miles (5 000 km) and 10,000 miles (16 000 km)
since your last oil change. Under severe conditions, the
indicator may come on before 3,000 miles (5 000 km).
Never drive your vehicle more than 10,000 miles
(16 000 km) or 12 months, (whichever occurs first),
without an oil and filter change.
The system won't detect dust in the oil. So if you drive in a
dusty area be sure to change your oil every 3,000 miles
(5 000 km) or sooner if the ENGINE OIL CHANGE SOON
message appears on the Driver Information Center (DIC).
Remember to reset the Oil Life System whenever the oil is
changed. For more information, see ªOil Life Systemº
in the Index.
+ A good time to check your brakes is during tire rotation.
See ªBrake System Inspectionº under ªPeriodic
Maintenance Inspectionsº in Part C of this schedule.
@ Whenever the tires are rotated, the Check Tire
Pressure System must be reset.
