Front Lift System
A two-position lift actuator (one per damper)
with 35 mm (1.5 in) of stroke will
hydraulically raise the front of the vehicle to
provide approximately 50 mm (2 in) of
increased clearance in approximately
three seconds (height and time will vary by
vehicle). The Front Lift System will allow
you to lift the front of the vehicle to enter a
driveway, driving over curbs, speed bumps
or onto ramps or a trailer.
To use the Front Lift System, press the
button on the center console to raise or
lower the vehicle. This feature can be
operated at speeds up to 38 km/h (24 mph)
when the engine is running. The system
functions based on the vehicle’s state or
operating mode:
.The system will not raise up when the
doors or underhood storage compartment
is open.
.The system can be raised or lowered by
the pushbutton, when the vehicle is in
RUN or in accessory mode.
.If the vehicle is in the raised position and
is driven at speeds above 38 km/h
(24 mph), it will automatically lower.
.If the vehicle is turned off, it will
automatically lower.
.If a vehicle door is opened during
lowering, the movement will pause for
15 seconds then continue to lower, but at
a slower rate.
If equipped, the front height can be raised
automatically using GPS navigation in the
vehicle. The vehicle will automatically lift in
up to 1,000 programmable locations. Once
the button is pushed, a notification will
appear on the Driver Information Center
(DIC) and prompt the driver if they would
like to “Remember” the location. The driver
can select this function through the steering
wheel controls, see Steering Wheel Controls
0 119.
The driver can also delete stored locations
for the automatic lift.
If the vehicle is raised automatically using
GPS, it will automatically lower once the
vehicle is located about 60 meters (197 feet)
from the programmed location. To disable
this function, turn off the GPS location via
the vehicle Customization Settings. The Front
Lift System will now only operate using the
pushbutton command, and the “Auto Lift
Location Remembered” confirmation
message will not display.

Launch Control (Sport and Track
Mode Only)
A Launch Control feature is available, within
Competitive Driving mode or PTM, on all
vehicles to allow the driver to achieve high
levels of vehicle acceleration in a straight
line. Launch Control is a form of TCS that
manages tire spin, and transmissions clutch,
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.
Caution
The new vehicle break-in period should be
completed before using the launch
control feature, otherwise performance
will be limited and damage may occur to
the powertrain/engine. See New Vehicle
Break-In 0177. Launch Control is only available when the
following criteria are met:
.Competitive Driving mode or any of the
PTM modes are selected (if equipped). See
Driver Mode Control
0196.
.The steering wheel must be straight.
.The driver door must be closed.
.The vehicle must be in D (Drive) or
M (Manual mode).
.The parking brake must not be engaged.
Launching the Vehicle
.Ensure the vehicle is in Competitive
Driving mode or any of the PTM modes.
.The brake pedal must be firmly pressed
to the floor, equivalent to a panic brake
event.
.While maintaining the brake pedal, the
accelerator pedal is rapidly applied to
wide open throttle. If the vehicle rolls due
to wide open throttle or engine speed
does not exceed 3,000 Revolutions Per
Minute (RPM), release the throttle, press
the brake pedal more firmly, and reapply
the accelerator to wide open throttle.
.If the engine is cold, the vehicle may
be limited to 3000 rpm until
conditions are suitable for
acceleration.

pedal to activate Launch Control.
7. Fully press the accelerator. Release thebrake pedal to launch the vehicle.
Limited-Slip Differential
The standard mechanical limited-slip
differential provides more traction on snow,
mud, ice, sand, or gravel. It works like a
standard axle most of the time, but when traction is low, this feature allows the drive
wheel with the most traction to move the
vehicle. See
Performance Driving 0206 and
Maintenance Schedule 0316.
Stingray, E-Ray, and Z06 Models Only
The Electrical Limited-Slip Differential (eLSD)
located on the rear axle is a hydraulically
actuated clutch system. It can infinitely vary
the clutch engagement between 0 and
2250 N*m (1659 lb-ft) of breakaway torque
between the rear wheels. When necessary it
responds from open to full engagement in
fractions of a second. 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. It is fully
integrated with the Active Handling and
Performance Traction Management (PTM)
systems (if equipped).
There are unique calibrations based on the
Traction Control System (TCS) setting. eLSD
modes change automatically when the
traction control button is 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 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 remains on. Vehicle
stability is still the priority, while allowing
for optimized traction out of corners.

not need service. Turn LKA off if these
conditions continue.
Fuel
Top Tier Fuel
GM recommends the use of TOP TIER
Detergent Gasoline to keep the engine clean,
reduce engine deposits, and maintain
optimal vehicle performance. Look for the
TOP TIER Logo or see www.toptiergas.com
for a list of TOP TIER Detergent Gasoline
marketers and applicable countries.
Recommended Fuel
Premium unleaded gasoline meeting ASTM
specification D4814 with a posted octane
rating (R+M)/2 of 91 or greater is required.
The use of the correct fuel is an important
part of the proper maintenance of the
vehicle and a condition of the vehicle
warranty. If heavy knocking is heard when
using gasoline rated at 91 or greater, the
engine needs service.
Do not use any fuel labeled E85 or FlexFuel.
Do not use gasoline with ethanol levels
greater than 15% by volume.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:
.For vehicles that are not FlexFuel, fuel
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.
.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
life of the emissions catalyst.

Warning (Continued)
3. Turn off the engine.
To be even more certain the vehicle will
not move, put blocks in front of and
behind the wheels.
{Warning
Getting under a vehicle when it is lifted
on a jack is dangerous. If the vehicle slips
off the jack, you could be badly injured
or killed. Never get under a vehicle when
it is supported only by a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can damage the
vehicle or the vehicle may fall and cause
injury to you or others.
If a jack is used to lift the vehicle, follow the
instructions that came with the jack, and be
sure to use the correct lifting points to
avoid damaging the vehicle.
Caution
Lifting the vehicle improperly can damage
it and result in costly repairs not covered
by the vehicle warranty. To lift the
vehicle properly and prevent vehicle
damage:
.Be sure to place a block or pad
between the jack and the vehicle.
.Lift only in the areas shown in the
following illustrations.
For additional information, see your
dealer and the service manual.
Caution
The front jack pads must not contact the
rocker panels, the front fenders, or the
floor pan. If they do, damage may occur. Lifting from the Front
–Frame
Use only a service jack with a lifting pad
diameter of 64 mm (2.5 in) or smaller, and

246 Vehicle Care
Engine Oil (5.5L LT6 Engine)
To ensure proper engine performance and
long life, pay careful attention to engine oil.
Follow these important steps:
.Use engine oil approved to the proper
specification and of the proper viscosity
grade. See“Selecting the Right Engine
Oil” later 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” later in this section.
.Change the engine oil at the appropriate
time. SeeEngine Oil Life System 0252.
.Always dispose of engine oil properly. See
“What to Do with Used Oil” in this
section.
Checking the Engine Oil
1. Engine Oil Dipstick
2. Engine Oil Fill Cap
Check the engine oil level regularly, every
650 km (400 mi), especially prior to a long
trip. To get an accurate reading, the vehicle
must be parked on a level ground.
The engine oil dipstick handle is a loop. See
Engine Compartment Overview 0238 for the
location.
The vehicle has a racetrack-ready dry sump
engine lubrication system. This high
performance system operates differently
than a standard engine lubrication system
and requires a special procedure when
checking the engine oil level. Follow this
procedure closely.
The engine oil level must be checked when
the engine is warm. Cold oil level in the dry
sump tank may not indicate the actual
amount of oil in the system. Engine oil is
contained in an external tank, separate from
the engine. Under normal operating
conditions, the oil pan under the engine
does not store any oil. If the vehicle has
been parked for an extended period without
the engine being started, some oil will seep
back into the oil pan. This will reduce the
amount of oil held in the dry sump tank and there could be no engine oil on the
dipstick. This is normal since the dipstick is
designed to read the engine oil level only
after the engine has run long enough to
reach normal operating temperature. Do not
add engine oil based on cold engine dipstick
readings. The engine oil level on the dipstick
must be checked while the engine is running
at idle.
To check the engine oil:
1. Turn the engine on and let it warm up to at least 80 °C (175 °F).
2. Once the engine is warm, check the oil while the engine is running at idle.
{Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
3. Remove the dipstick and wipe it with a clean lint-free paper towel or a cloth.
Re-insert the dipstick and push it all the
way in until it stops.
