Engine Oil Additives / Engine Oil
Flushes
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM Standard
GM6094M are all that is needed for good performance
and engine protection.
Engine oil system flushes are not recommended and
could cause engine damage not covered by the vehicle
warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that indicates when
to change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change is indicated can vary considerably.
For the oil life system to work properly, the system must
be reset every time the oil is changed.When the system has calculated that oil life has been
diminished, it indicates that an oil change is necessary.
A CHANGE OIL SOON message comes on. SeeDIC
Warnings and Messages on page 4-41. Change the oil
as soon as possible within the next 600 miles (1 000 km).
It is possible that, if driving under the best conditions, the
oil life system might not indicate that an oil change is
necessary for over a year. However, the engine oil and
filter must be changed at least once a year and at this
time the system must be reset. Your dealer/retailer has
trained service people who will perform this work using
genuine parts and reset the system. It is also important
to check the oil regularly and keep it at the proper level.
If the system is ever reset accidentally, the oil must be
changed at 3,000 miles (5 000 km) since the last oil
change. Remember to reset the oil life system whenever
the oil is changed.

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to change
the engine oil and filter based on vehicle use. Whenever
the oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation occurs
where the oil is changed prior to a CHANGE OIL SOON
message being turned on, reset the system.
After changing the engine oil and filter, the system must
be reset. To reset the oil life system:
1. Turn the ignition key to ON/RUN with the
engine off.
2. With the CHANGE OIL SOON message displayed,
press either of the DIC buttons to clear the message.
SeeDIC Warnings and Messages on page 4-41.
3. Display OIL LIFE RESET on the DIC.
4. Press and hold the INFO button for at least one
second. An ACKNOWLEDGED message displays
for three seconds or until the next button is pressed.
This tells you the system has been reset.
SeeDIC Vehicle Personalization on page 4-45.
5. Turn the key to LOCK/OFF.
If the CHANGE OIL SOON message comes back on
when the vehicle is started, the engine oil life system
has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that can 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
filter 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. Recycle it by taking it to a
place that collects used oil.

Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your vehicle is damaged in a crash, the
headlamp aim may be affected. Aim adjustment to the
low-beam headlamps may be necessary if oncoming
drivers flash their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be re-aimed, it is
recommended that you take the vehicle to your
dealer/retailer for service.
Bulb Replacement
For the proper type of replacement bulbs, see
Replacement Bulbs on page 6-42.
For any bulb changing procedure not listed in this
section, contact your dealer/retailer.

Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and follow
the instructions on the bulb package.

When rotating the vehicle’s tires, always use the
correct rotation pattern shown here.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the Tire
and Loading Information label. SeeIn ation - Tire
Pressure on page 6-49andLoading the Vehicle on
page 5-20.Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation on page 6-52.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications.
{WARNING:
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 a crash. 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.

Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service
for new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). SeeTire Inspection
and Rotation on page 6-55.
Scheduled Maintenance
When the Change Oil Soon Message
Displays
Change engine oil and filter. SeeEngine Oil on
page 6-15.An Emission Control Service.
When the Change Oil Soon message displays, service
is required for the vehicle as soon as possible, within
the next 1 000 km/600 miles. If driving under the best
conditions, the engine oil life system might not indicate
the need for vehicle service for more than a year.

year and the oil life system must be reset. Your dealer/
retailer has trained service technicians who will perform
this work and reset the system. If the engine oil life
system is reset accidentally, service the vehicle within
5 000 km/3,000 miles since the last service. Reset the
oil life system whenever the oil is changed. SeeEngine
Oil Life System on page 6-18.When the Change Oil Soon message displays,
certain services, checks, and inspections are required.
The services described for MaintenanceIshould be
performed at every engine oil change. The services
