How to Reset the Engine Oil
Life System
The Engine Oil Life System calculates when to change
your engine oil and lter based on vehicle use.
Anytime your oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
CHANGE ENGINE OIL SOON message being
turned on, reset the system.
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Engine
Oil Life System, do the following:
1. Display the OIL LIFE REMAINING on the DIC.
2. Press and hold the SET/RESET button on the DIC
for more than ve seconds. The oil life will change
to 100%.
If the CHANGE ENGINE OIL SOON message comes
back on when you start your vehicle, the Engine Oil Life
System has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a goodhand cleaner. Wash or properly dispose of 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 threat to the environment. If you
change your own oil, be sure to drain all the oil from the
lter before disposal. Never 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 used oil, ask your
dealer, a service station, or a local recycling center
for help.
Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 5-12for
the location of the engine air cleaner/lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change after each
50,000 mile (83 000 km) interval. SeeScheduled
Maintenance on page 6-4for more information. If you
are driving in dusty/dirty conditions, inspect the lter
at each engine oil change.
5-19

The system can alert you about a low tire — but it does
not replace normal tire maintenance. SeeTires on
page 5-56.
When the tire pressure warning light and the CHECK
TIRE PRESSURE message comes on, you should stop
as soon as you can and check all your tires for
damage. If a tire is at, seeIf a Tire Goes Flat on
page 5-72. Also check the tire pressure in all four tires
as soon as you can. SeeInation - Tire Pressure
on page 5-62.
Any time you adjust a tire’s pressure or have one or
more tires repaired or replaced, you will need to reset
(calibrate) the check tire pressure system. You will
also need to reset the system whenever you rotate the
tires, buy new tires, and install or remove the compact
spare tire.
Do not reset the check tire pressure system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires to the
recommended amount. SeeInation - Tire Pressure on
page 5-62. If you reset the system when the tire
pressures are incorrect, the check tire pressure system
will not work properly and may not alert you when a
tire is low or high.To reset (calibrate) the system:
1. Turn the ignition switch to RUN, with the engine off.
2. Press the vehicle information button on the DIC
until the PRESS
VTO RESET TIRE SYSTEM
message appears on the display.
3. Press and hold the DIC Set/Reset button for about
ve seconds. After ve seconds, the display will
show TIRE PRESSURE SYSTEM RESET. If the
TIRE PRESSURE SYSTEM RESET message does
not appear in the display after about ve seconds,
repeat the procedure starting with Step 2. If it does
not work after two tries, see your dealer for service.
The system completes the calibration process during
driving. The system learns the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 20 and 45 minutes of
driving in each of the following speed ranges to learn tire
pressures: 25 to 40 mph (40 to 64 km/h), 40 to 60 mph
(64 to 96 km/h), and 60 to 85 mph (96 to 136 km/h). This
time may be longer depending on your individual driving
habits. Learning need not be accumulated during a single
trip. Once learned, the system will remember the tire
pressures until the system is reset.
5-64

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 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. SeeWhen It Is Time
for New Tires on page 5-66andWheel Replacement
on page 5-70for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeeScheduled Maintenance
on page 6-4.
When rotating your vehicle’s tires, always use the
correct rotation pattern shown here.
Do not include the compact spare tire in your vehicle’s
tire rotation.After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label. SeeLoading Your Vehicle on
page 4-29.
Reset the check tire pressure system, if your vehicle
one. SeeCheck Tire Pressure System on page 5-63for
additional information.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-101.
{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 needed, to get all
the rust or dirt off. SeeChanging a Flat Tire on
page 5-72.

Scheduled Maintenance
When the CHANGE ENGINE OIL SOON message in
the Driver Information Center (DIC) comes on, it means
that service is required for your vehicle. Have your
vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if you are
driving under the best conditions, the engine oil life
system may not indicate that vehicle service is
necessary for over a year. However, your engine oil and
lter must be changed at least once a year and at
this time the system must be reset. Your GM
Goodwrench
®dealer has GM-trained service technicians
who will perform this work using genuine GM parts
and reset the system.
If the engine oil life system is ever reset accidentally,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 5-18for information on
the Engine Oil Life System and resetting the system.When the CHANGE ENGINE OIL SOON message
appears, certain services, checks, and inspections are
required. Required services are described in the
following for “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that your rst service be
MaintenanceI, your second service be MaintenanceII,
and that you alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases, MaintenanceII
may be required more often.
MaintenanceI— Use MaintenanceIif the
CHANGE ENGINE OIL SOON message comes on
within 10 months since the vehicle was purchased or
MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message comes on
10 months or more since the last service or if the
message has not come on at all for one year.
