How to Reset the CHANGE ENGINE OIL
Message
The GM 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
message in the Driver Information Center (DIC) being
turned on, reset the system.
After the oil has been changed, the CHANGE ENGINE
OIL message must be reset. To reset the message,
do the following:
1. Turn the key to the ON position without starting the
engine.
2. Press the INFO button on the Driver Information
Center (DIC) until ENGINE OIL LIFE is displayed.
3. Press and hold the INFO RESET button until 100%
ENGINE OIL LIFE is displayed. This resets the oil
life indicator.
4. Turn the key to OFF.
If the CHANGE ENGINE OIL message comes back on
when you start your vehicle, the engine oil life system
has not reset. Repeat the procedure.The percentage of oil life remaining may be checked at
any time by pressing the INFO button until ENGINE OIL
LIFE is displayed on the DIC. For more information on the
oil life indicator, seeOil Life Indicator on page 3-89.
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 good
hand 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 your used oil, ask your dealer, a
service station or a local recycling center for help.

Headlamp Aiming
Your vehicle has a visual optical headlamp aiming system
which may be equipped with horizontal aim indicators.
The aim has been preset at the factory and should need
no further adjustment. This is true even though your
horizontal aim indicators (if equipped) may not fall exactly
on the “0” (zero) marks on their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers (for
horizontal aim), or if oncoming drivers ash their high
beams at you (for vertical aim). If you believe your
headlamps need to be re-aimed, we recommend that
you take your vehicle to your dealer for service.
However, it is possible for you to re-aim your headlamps
as described in the following procedure.Notice:To make sure your headlamps are aimed
properly, read all the instructions before beginning.
Failure to follow these instructions could cause
damage to headlamp parts.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps are
25 ft. (7.6 m) from a light colored wall or other at
surface.
The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other at surface.
The vehicle should be placed so it is perpendicular
to the wall or other at surface.
The vehicle should not have any snow, ice or mud
attached to it.
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs. (75 kg)
on the driver’s seat.
Tires should be properly inated.
5-55

Notice:Do not use a tire sealant if your vehicle is
equipped with Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
Once a low or high tire pressure condition is detected,
the TPM system will display the CHECK TIRE
MESSAGE each time the engine is started, until the
tire(s) are set to the correct ination pressure.
The Tire-Loading Information Label, which is located on
the rear edge of the driver’s door, shows the correct
ination pressure for the tires on your vehicle.
The TPM system also allows the driver to check the air
pressure status of each road tire using the Driver
Information Center (DIC). Each tire’s air pressure will be
listed individually, in the following order: LF (left front
or driver’s side front tire), RF (right front or passenger’s
side front tire), RR (right rear or passenger’s side
rear tire) and LR (left rear or driver’s side rear tire). See
Ination - Tire Pressure on page 5-74for information
regarding correct tire ination. Also, seeDriver
Information Center (DIC) on page 3-62for information
on the DIC controls and displays.If the DIC display does not show tire pressures or the
SERVICE TPM SYSTEM message appears, see
your dealer for service. The TPM system may not work
properly while the compact spare tire is installed.
Anytime you replace one or more tires or rotate your
tires, the TPM system will need to be reset. A special
tool is needed to reset the sensor identication
codes. See your dealer for service.
Your vehicle was delivered from the factory with
aluminum valve stem caps. If you ever have to replace
the valve stem caps on your vehicle, you should
replace them with aluminum or plastic caps.
The TPM system can alert you about a low or high tire
pressure condition, but it does not replace normal
tire maintenance. SeeTires on page 5-66.
5-77

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 5-79andWheel Replacement
on page 5-82for 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 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 ination pressures as shown on the Tire and
Loading Information label.
Vehicles equipped with the Tire Pressure Monitor (TPM)
system will need to have the sensors reset after a tire
rotation is performed. A special tool is needed to
reset the sensor identication codes. See your dealer
for service.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-115.

If you want to get service information, seeService
Publications Ordering Information on page 7-12.
Owner Checks and Services on page 6-9tells you what
should be checked, when to check it and what you can
easily do to help keep your vehicle in good condition.
The proper replacement parts, uids and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 6-13andNormal Maintenance Replacement
Parts on page 6-14. When your vehicle is serviced,
make sure these are used. All parts should be replaced
and all necessary repairs done before you or anyone
else drives the vehicle. We recommend the use of
genuine GM parts.
Scheduled Maintenance
When the CHANGE ENGINE OIL 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 on page 5-15for information on the Engine
Oil Life System and resetting the system.
When the change engine oil 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 MaintenanceIIand that you
alternate MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.
MaintenanceI— Use MaintenanceIif the change
engine oil message comes on within ten months since
vehicle was purchased or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message comes on ten
months or more since the last service or if the message
has not come on at all for one year.
