Starting the Engine
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
The shift lever should be in NEUTRAL and the parking
brake engaged. Hold the clutch pedal to the oor and
start the engine. Your vehicle will not start if the clutch
pedal is not all the way down — that is a safety feature.
1. With your foot off the accelerator pedal, turn your
ignition key to START. Then, let go of the key; the
engine will start automatically. The idle speed
will go down as your engine gets warm. Do not race
the engine immediately after starting it. Operate
the engine and transmission gently until the
oil warms up and lubricates all moving parts.Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects the electrical system. If the
ignition key is turned to the START position,
and then released when the engine begins cranking,
the engine will continue cranking until the vehicle
starts or until it exceeds the maximum cranking time
allowed, approximately 15 seconds to prevent
cranking motor damage. To prevent starter-motor
gear damage, this system also prevents cranking if
the engine is already running. The engine cranking
can be stopped by turning the ignition switch to
the ACCESSORY or OFF position.
2. If your engine will not start, or starts but then stops,
it could be ooded with too much gasoline. Try
pushing your accelerator pedal all the way to the
oor and holding it there as you turn the key
to START. If the vehicle starts briey but then stops
again, do the same thing.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.

Using the Six-Disc CD Changer
The CD player can play the smaller 3 inch (8 cm) single
CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.
If playing a CD-R, the sound quality may be reduced due
to CD-R quality, the method of recording, the quality of
the music that has been recorded, and the way the CD-R
has been handled. There may be an increase in skipping,
difficulty in nding tracks, and/or difficulty in loading and
ejecting. If these problems occur, check the bottom
surface of the CD. If the surface of the CD is damaged,
such as cracked, broken, or scratched, the CD will not
play properly. If the surface of the CD is soiled, seeCare
of Your CDs on page 3-103for more information.
If there is no apparent damage, try a known good CD.
Do not add any label to a CD, it could get caught in the
CD player. If a CD is recorded on a personal computer
and a description label is needed, try labeling the top of
the recorded CD with a marking pen instead.
Notice:If you add any label to a CD, insert more
than one CD into the slot at a time, or attempt
to play scratched or damaged CDs, you could
damage the CD player. When using the CD player,
use only CDs in good condition without any
label, load one CD at a time, and keep the CD player
and the loading slot free of foreign materials,
liquids, and debris.

Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.
The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, your wheels
are not rolling. In the steering or cornering skid, too much
speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
A cornering skid is best handled by easing your foot
off the accelerator pedal.
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.
Competitive Driving
See your warranty book before using your vehicle for
competitive driving.
Notice:If you use your vehicle for 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
competitive driving and keep the level at or near 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 5-16.
4-18

Oils meeting these
requirements should
also have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certied by the American
Petroleum Institute (API).
You should look for this on the oil container, and
use only those oils that are identied as meeting
GM Standard GM4718M and have the starburst
symbol on the front of the oil container.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 the oil. The recommended
oils with the starburst symbol that meet GM standards
are all you will need for good performance and
engine protection.
5-19

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.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is necessary.
A change engine oil message in the Driver Information
Center (DIC) will come on. 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.
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 engine oil
message in the DIC being turned on, reset the system.
After the oil has been changed, the change engine
oil message and the oil life indicator must be reset.
To reset the message and indicator, use one of
the following procedures:
Base Audio System
Press the CLR button located to the right of the DIC
display to acknowledge the change engine oil message.
This will clear the message from the display and reset it.
To reset the oil life indicator, use the following steps:
1. Press the up or down arrow on the INFO button
located to the right of the DIC display to access
the DIC menu.
2. Once XXX% ENGINE OIL LIFE menu item is
highlighted, press and hold the CLR button.
The percentage will return to 100, and the oil life
indicator will be reset. Repeat the steps if the
percentage does not return to 100.
3. Turn the key to OFF.
5-20

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.
Navigation System
If you have the navigation system, see “Vehicle
Customization” in the Navigation System Manual for
how to reset the oil life indicator.
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
The engine air cleaner/lter is in the engine
compartment on the driver’s side of the vehicle, near
the front. SeeEngine Compartment Overview on
page 5-12for more information on location.CTS shown, CTS-V similar
