Trip Computer
Oil Life Indicator
This feature lets you know when to change the engine
oil. It is based on the engine oil temperatures and
your driving patterns.
To see the display, press the information button
several times until OIL LIFE appears. If you see 99%
OIL LIFE, 99 percent of your current oil life remains.
The DIC may display a CHANGE OIL NOW message.
If you see CHANGE OIL NOW, it means the oil life
is gone. For more information, seeScheduled
Maintenance on page 7-4andEngine Oil on page 6-15.
When the oil is changed, you will need to reset the
system. SeeEngine Oil Life System on page 6-18.
Always keep a written record of the mileage and date
when you changed your oil.
Audio System(s)
Determine which radio your vehicle has and then read the
pages following to familiarize yourself with its features.
Driving without distraction is a necessity for a safer
driving experience. SeeDefensive Driving on page 5-2.
By taking a few moments to read this manual and get
familiar with your vehicle’s audio system, you can use it
with less effort, as well as take advantage of its features.
While your vehicle is parked, set up your audio system by
presetting your favorite radio stations, setting the tone
and adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite stations
using the presets and steering wheel controls if the
vehicle has them.
{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and you
or others can be injured or killed. Always keep
your eyes on the road and your mind on the
drive — avoid engaging in extended searching
while driving.

Remember: Any traction control system helps avoid only
the acceleration skid. If your traction control system is
off, then an acceleration skid is also best handled
by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety,
you will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try your
best to avoid sudden steering, acceleration, or braking,
including reducing vehicle speed by shifting to a lower
gear. Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until your
vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow on
the road to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Anti-Lock Brake System (ABS) helps
avoid only the braking skid.Racing or Other Competitive
Driving (XLR-V)
See your warranty book before using your vehicle for
racing or other competitive driving.
Notice:If you use your vehicle for racing or
other competitive driving, the engine may use
more oil than it would with normal use. Low oil
levels can damage the engine. Be sure to check the
oil level often during racing or other competitive
driving and keep the level at or near 2 quarts (2 L)
above the upper mark that shows the proper
operating range on the engine oil dipstick.
For information on how to add oil, seeEngine Oil
on page 6-15. After the competitive driving, remove
excess oil so that the level on the dipstick is not
above the upper mark that shows the proper
operating range.
5-18

Your vehicle’s engine is lled at the factory with a
Mobil 1®synthetic oil, which meets all requirements
for your vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
may not be available. You can add substitute oil
designated SAE 5W-30 with the starburst symbol at all
temperatures. Substitute oil not meeting GM Standard
GM4718M should not be used for an oil change.
Engine Oil Additives
Do not add anything to your oil. The recommended oils
with the starburst symbol that meet GM Standard
GM4718M are all you will need for good performance
and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you know
when to change the engine oil and lter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions, the
mileage at which an oil change will be indicated can vary
considerably. For the oil life system to work properly, you
must reset the system every time the oil is changed.Notice:If your vehicle is an XLR-V model, the
engine uses a special oil lter. The use of any other
engine oil lter could lead to lter failure and
result in severe engine damage. Damage caused by
use of the wrong engine oil lter would not be
covered by your new vehicle warranty.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is necessary.
A CHANGE OIL NOW message in the DIC will come on.
SeeDIC Warnings and Messages on page 3-67. Change
your oil 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 oil life system may not indicate that
an oil change 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 dealer
has GM-trained service people who will perform this work
using genuine GM parts and reset the system. It is also
important to check your oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.
6-18

How to Reset the Engine Oil Life
System and the Oil Life Indicator
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 OIL NOW message in the DIC being turned
on, reset the system.
After the oil has been changed, the CHANGE OIL NOW
message and the oil life indicator must be reset.
To reset the message use the following procedure:
1. Press the up or down arrow to scroll the DIC
to show OIL LIFE.
2. Once the XXX% ENGINE OIL LIFE menu item is
highlighted, press and hold the RESET button until
the percentage shows 100%.
If the percentage does not return to 100% or if
the CHANGE OIL NOW 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
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.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 6-12
for the location of the engine air cleaner/lters.
When to Inspect the Engine
Air Cleaner/Filters
Inspect the air cleaner/lters at the MaintenanceII
intervals and replace them at the rst oil change
after each 50,000 mile (83 000 km) interval. See
Scheduled Maintenance on page 7-4for more
information. If you are driving in dusty/dirty conditions,
inspect the lters at each engine oil change.
How to Inspect the Engine
Air Cleaner/Filters
To inspect the air cleaner/lters, remove the lters
from the vehicle and lightly shake the lters to release
loose dust and dirt. If the lters remain caked with
dirt, new lters are required.To inspect or replace the lters, do the following:
1. Flip the clasps on the top of the engine air
cleaner/lter cover forward to unlatch the cover.
2. Lift the front of the cover at an angle and remove.
This is necessary due to the four tabs located on
the rear of the cover.
3. Remove the engine air cleaner/lter element
and any loose debris that may be found in the
air cleaner base.
4. Inspect or replace the lter.
5. Repeat the procedure for the second
air cleaner/lter.

If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
2. Set the climate controls to the highest heat setting
and fan speed and open the windows as necessary.
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning does not come back on,
you can drive normally.
If the warning continues, pull over, stop, and park
your vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. If you still have the
warning, turn off the engine and get everyone out of
the vehicle until it cools down. Also, see “Overheated
Engine Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get service
help right away.Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be driven
to a safe place in an emergency situation. If an
overheated engine condition exists and the DIC
message ENGINE HOT, STOP ENGINE is displayed,
an overheat protection mode which alternates ring
groups of cylinders helps prevent engine damage.
In this mode, you will notice a signicant loss in
power and engine performance. Driving extended
miles (km) in the overheat protection mode 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 will be severely degraded.
Repair the cause of coolant loss, change the oil
and reset the oil life system. SeeEngine Oil
on page 6-15.

Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts or
wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts, or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts, and wheel nuts for replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire clearance to
the body and chassis.
{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 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.
{CAUTION:
Never use oil or grease on studs or the
threads of the wheel nuts. If you do, the wheel
nuts might come loose and the wheel could
fall off, causing a crash.
