Caution
During a first time track or racing
event, high axle temperatures can
occur. Damage could be caused
to the axle and would not be
covered by the vehicle warranty.
Do not drive as long or as fast the
first time the vehicle is driven on
the track or raced.

specification. If this oil is not
available, the following oils can be
used as an alternative: Valvoline
®
SYNPOWER MST 5W-40, Mobil®1
ESP Formula M 5W-40. See
Capacities and Specifications 0338.
This requires premium fuel, and
comes standard with a 10 qt sump,
air/oil separator, integrated oil
cooler, and other powertrain and
powertrain cooling components in
preparation for track use.
Check the oil level often during track
events and competitive driving and
keep the oil level at or near the
upper mark.
Brake Fluid
For track events and competitive
driving, it is recommended that the
brake fluid be replaced with a high
performance brake fluid that has a
dry boiling point greater than 279 °C
(534 °F). After conversion to the
high performance brake fluid, follow
the brake fluid service
recommendations outlined by the
fluid manufacturer. Do not use
silicone or DOT-5 brake fluids.
Caution
Removing the splash shield can
degrade wet braking
performance, as well as introduce
brake pedal pulsation, due to
brake disc exposure to road
debris. Only remove the front
brake disc splash shield and front
tire deflector when driving in track
events.
Brake cooling can be improved if
the front brake disc splash shield
and front tire deflector are removed.
Removing the shield will require that

To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0261.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle must be on level ground. The
engine oil dipstick handle is a loop.
See
Engine Compartment Overview
0 252 for the location of the engine
oil dipstick.
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
2. Pull out the dipstick and wipe it with a clean paper towel or
cloth, then push it back in all
the way. Remove it again,
keeping the tip down, and
check the level.

When to Add Engine Oil
2.0L LTG L4 Engine
3.6L LF3 V6 Twin Turbo
3.6L LGX V6 Engine Shown, 6.2LLT4 V8 Engine Similar
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
and then recheck the level. See “Selecting the Right Engine Oil”
in
this section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications 0338.
Caution
Do not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level above the
operating range, i.e., the engine
has so much oil that the oil level
gets above the cross-hatched
area that shows the proper
operating range, the engine could
be damaged. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
See Engine Compartment Overview
0 252 for the location of the engine
oil fill cap. Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
See
Recommended Fluids and
Lubricants 0333.
Specification
Ask for and use engine oils that
meet the dexos1™ specification.
Engine oils that have been
approved by GM as meeting the
dexos1 specification are marked
with the dexos1 approved logo.

system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and at this time the system must be
reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
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
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:1. Using the DIC buttons, display
REMAINING OIL LIFE on the
DIC. See Driver Information
Center (DIC) 0129 andEngine
Oil Messages 0138.
2. Press and hold SEL to clear the CHANGE ENGINE OIL
SOON message and reset the
oil life at 100%.
Be careful not to reset the oil
life display accidentally at any
time other than after the oil is
changed. It cannot be reset
accurately until the next oil
change.
The oil life system can also be reset
as follows: 1. Turn the ignition on with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
If the CHANGE ENGINE OIL
SOON message is not on, the
system is reset.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off. If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.

How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact your
dealer for additional information.
