iand StabiliTrak/ESC OFF
light
gwill go out.
Launch Control
If equipped, Launch Control is available
within Competitive Driving Mode and
Performance Traction Management (PTM) to
allow high levels of vehicle acceleration in a
straight line. Launch Control is a form of
traction control that manages tire spin while
launching the vehicle. This feature is
intended for use during closed course race
events where consistent zero to
60 and quarter mile times are desirable.
Launch Control is only available when the
following criteria are met:
.Competitive Driving Mode is selected or
any of the Performance Traction
Management modes are selected. The
traction off light comes on in the
instrument cluster and the appropriate
Driver Information Center (DIC) message
displays.
.The vehicle is not moving.
.The steering wheel is pointing straight.
Manual Transmissions
.The clutch is fully pressed and the
transmission is in 1 (First) gear.
.The accelerator pedal is rapidly applied
and held to wide open throttle. Launch Control will initially limit engine
speed as you rapidly apply the accelerator
pedal to wide open throttle. Allow the
engine rpm to stabilize. A smooth, quick
release of the clutch, while maintaining the
fully pressed accelerator pedal, will manage
wheel slip.
Automatic Transmissions
.The brake pedal is firmly pressed to the
floor, equivalent to a panic brake event.
.The accelerator pedal is rapidly applied to
wide open throttle. If the vehicle rolls due
to wide open throttle, release the
throttle, press the brake pedal more
firmly, and re-apply the accelerator to
wide open throttle.
Launch Control will initially limit engine
speed as you rapidly apply the accelerator
pedal to wide open throttle. Allow the
engine rpm to stabilize. A smooth, quick
release of the brake pedal, while
maintaining the fully pressed accelerator
pedal, will manage wheel slip.
After the vehicle is launched, the system
continues in Competitive Driving Mode
or PTM.

24 Driving and Operating
Competitive Driving Mode, PTM, and Launch
Control are systems designed for a closed
course race track and not intended for use
on public roads. The systems are not
intended to compensate for lack of driver
experience or familiarity with the race track.
Custom Launch Control may be available
through the Settings menu, if equipped. See
“Custom Launch Control”in Track Events and
Competitive Driving in the owner’s manual.
Limited-Slip Differential
The Electronic Limited-Slip Differential (eLSD)
is a hydraulically actuated clutch system.
It can infinitely vary the clutch engagement
between 0 and 2000 Y(1475 lb ft) of
breakaway torque between the rear wheels.
It responds to full engagement within
0.150 seconds when necessary. Smaller
clutch adjustments happen even faster.
The eLSD:
.Uses the vehicle sensors and driver inputs
to determine the optimum amount of
clutch engagement for the conditions.
.Improves traction while cornering by
changing the engagement to achieve a
balance between directional control and
acceleration.
.Provides optimal engagement for
high-speed control and stability without
affecting precise steering and turn-in.
.Improves vehicle stability during spirited
driving and evasive maneuvers. Is fully
integrated with the Active Handling and
Performance Traction Management (PTM)
systems.
There are unique calibrations based on the
Traction Control System (TCS) setting. eLSD
modes change automatically when
Yis
pressed. No unique input from the driver is
required.
.Mode 1 is the standard mode when the
vehicle is started. It provides a touring
calibration with an emphasis on vehicle
stability. Mode 1 is also used in PTM
Wet mode.
.Mode 2 is engaged when both TCS and
StabiliTrak/Electronic Stability Control
(ESC) are turned off. This calibration
provides more nimble corner turn-in, and
is biased for better traction out of
corners.
.Mode 3 is engaged when PTM is engaged
in Dry, Sport 1 & 2, and Race modes. This
is a nimble calibration with similar
functionality as eLSD Mode 2, however, it
is integrated to work with PTM.
.Mode 4 is engaged when TCS is selected
off, but StabiliTrak/ESC remains on.
Vehicle stability is still the priority, while
allowing for optimized traction out of
corners.
The ZL1 1LE, ZL1 coupe, and SS 1LE are
calibrated uniquely and optimized for their
unique powertrain and chassis combinations.

labeled greater than 15% ethanol by
volume, such as mid-level ethanol
blends (16–50% ethanol), E85,
or FlexFuel.
.Fuel with any amount of methanol,
methylal, ferrocene, and aniline. These
fuels can corrode metal fuel system
parts or damage plastic and rubber
parts.
(Continued)
Caution (Continued)
.Fuel containing metals such as
methylcyclopentadienyl manganese
tricarbonyl (MMT), which can damage
the emissions control system and
spark plugs.
.Fuel with a posted octane rating of
less than the recommended fuel. Using
this fuel will lower fuel economy and
performance, and may decrease the

Engine Oil
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” in the
owner’s manual.
.Always dispose of engine oil properly. See
“What to Do with Used Oil” in this
section.
Checking Engine Oil
Check the engine oil level regularly, every
650 km (400 mi), especially prior to a long
trip. The engine oil dipstick handle is a loop.
See Engine Compartment Overview 027 for
the location.
{Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
If a low oil Driver Information Center (DIC)
message displays, check the oil level.
Follow these guidelines:
.To get an accurate reading, park the
vehicle on level ground. Check the engine
oil level after the engine has been off for
at least two hours. Checking the engine
oil level on steep grades or too soon after
engine shutoff can result in incorrect readings. Accuracy improves when
checking a cold engine prior to starting.
Remove the dipstick and check the level.
.If unable to wait two hours, the engine
must be off for at least 15 minutes if the
engine is warm, or at least 30 minutes if
the engine is not warm. Pull out the
dipstick, 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
If the oil is below the cross-hatched area at
the tip of the dipstick and the engine has
been off for at least 15 minutes, add 1 L (1
qt) of the recommended oil and then
recheck the level. See
“Selecting the Right
Engine Oil” later in this section for an
explanation of what kind of oil to use. For
engine oil crankcase capacity, see Capacities
and Specifications 043.

Vehicle Care 29
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 the oil level is 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. Drain the excess oil or limit
driving of the vehicle, and seek a service
professional to remove the excess oil.
See Engine Compartment Overview 027 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 041. Specification
Use engine oils that meet the dexos2
specification. Engine oils that have been
approved by GM as meeting the dexos2
specification are marked with the dexos2
approved logo. See www.gmdexos.com.
Caution
Failure to use the recommended engine
oil or equivalent can result in engine
damage not covered by the vehicle
warranty.
Viscosity Grade
Use SAE 0W-40 viscosity grade engine oil for
the LT1 and LT4 engines.
When selecting an oil of the appropriate
viscosity grade, it is recommended to select
an oil of the correct specification. See
“Specification” earlier in this section. If 0W-40 dexos2 oil is not available, SAE
5W-30 dexos1 full synthetic engine oil may
be used for street use.
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the dexos
specification 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.
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 or pouring it on the ground, into
