Driving and Operating 9-37
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of the
vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. SeeCruise Control on
page 9-47.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle. It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See
If the Vehicle Is Stuck on
page 9-13 and“Turning the
Systems Off and On” later in this
section.
The indicator light for both systems
is in the instrument cluster. This
light will:
.Flash when TCS is limiting
wheel spin.
.Flash when StabiliTrak is
activated.
.Turn on and stay on when either
system is not working. If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on
and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.

are systems designed to allow
increased performance while
accelerating and/or cornering. This
is accomplished by regulating and
optimizing the engine, brakes, and suspension performance. These
modes are for use at a closed
course race track and are not
intended for use on public roads.
They will not compensate for driver
inexperience or lack of familiarity
with the race track. Drivers who
prefer to allow the system to have
more control of the engine, brake,
and suspension are advised to turn
the normal traction control and
StabiliTrak systems on.
{Caution
Attempting to shift when the drive
wheels are spinning and do not
have traction may cause damage
to the transmission. Damage
caused by misuse of the vehicle
is not covered by the vehicle
warranty. Do not attempt to shift
when the drive wheels do not
have traction.
Competitive Driving Mode
(Except Z51 with Magnetic
Selective Ride Control)
Competitive Driving Mode allows full
engine power while StabiliTrak
helps maintain directional control of
the vehicle by selective brake
application. In this mode, TCS is off
and Launch Control is available.

Launch Control (Track
Mode Only)
A Launch Control feature is
available, within Competitive Driving
Mode (except Z51 with Magnetic
Selective Ride Control) or Performance Traction Management
(Z51 with Magnetic Selective Ride
Control), on all vehicles to allow the
driver to achieve 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 (except Z51 with
Magnetic Selective Ride Control)
or any of the Performance
Traction Management modes
are selected (Z51 with Magnetic
Selective Ride Control). The
TCS light comes on the
instrument panel and the
appropriate DIC message
displays.
.The vehicle is not moving.
.The steering wheel is pointing
straight.
Manual Transmissions
.The clutch is pressed and the
vehicle is in 1 (First) gear.
.The accelerator pedal is rapidly
applied to wide open throttle.
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies 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. Complete shifts

manage wheel slip.
After the vehicle is launched, the
system continues in Competitive
Mode (except Z51 with Magnetic
Selective Ride Control) or Performance Traction Management
(Z51 with Magnetic Selective Ride
Control).
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.
Limited-Slip Differential
(Except Z51)
If equipped, the mechanical
limited-slip differential can give 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.
Limited-Slip Differential
(Z51 Only)
If equipped, the Electronic Limited
Slip Differential (ELSD) is
automatically activated. ELSD
actively monitors vehicle sensors
and driver inputs to determine the
amount of change for the
conditions. With ELSD, the
vehicle has:
.Enhanced high-speed control.
.Improved traction through
corners, allowing more
acceleration.
.More precise steering.
.Increased vehicle agility.
.Integration with StabiliTrak.

Fuel
Use of the recommended fuel is an
important part of the proper
maintenance of this vehicle. When
driving in the U.S. and Canada, to
help keep the engine clean and
maintain optimum vehicle
performance, we recommend TOP
TIER Detergent Gasolines. See
www.toptiergas.com for a list of TOP
TIER Detergent Gasolines.

Black plate (52,1)Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
6007198) - 2014 - CRC - 2/5/14
9-52 Driving and Operating
Use premium unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 91 or
higher. If the octane is less than 91,
damage to the engine may occur
and may void the vehicle warranty.
If heavy knocking is heard when
using gasoline rated at 91 octane or
higher, the engine needs service.
Use of Seasonal Fuels
Use summer and winter fuels in the
appropriate season. The fuels
industry automatically modifies the
fuel for the appropriate season.
If fuel is left in the vehicle tank for
long periods of time, driving or
starting could be affected. Drive the
vehicle until the fuel is at one-half
tank or less, then refuel with the
current seasonal fuel.Prohibited Fuels
Gasolines containing oxygenates
such as ethers and ethanol, as well
as reformulated gasolines, are
available in some cities. If these
gasolines comply with the
previously described specification,
then they are acceptable to use.
However, E85 (85% ethanol) and
other fuels containing more than
15% ethanol must be used only in
FlexFuel vehicles.
{Caution
Do not use fuel containing
methanol. It can corrode metal
parts in the fuel system and also
damage plastic and rubber parts.
That damage would not be
covered under the vehicle
warranty.Some gasolines, mainly high octane
racing gasolines, can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use
gasolines and/or fuel additives with
MMT as they can reduce spark plug
life and affect emission control
system performance. The
malfunction indicator lamp may turn
on. If this occurs, see your dealer
for service.
Gasoline Specifications
At a minimum, gasoline should meet
ASTM specification D 4814. Some
gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. See
“Prohibited
Fuels" in Fuel on page 9-51.

Driving and Operating 9-53
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle may not pass a smog-check
test. SeeMalfunction Indicator
Lamp on page 5-15. If this occurs,
return to your authorized dealer for
diagnosis. If it is determined that the
condition is caused by the type of
fuel used, repairs may not be
covered by the vehicle warranty.
Fuels in Foreign
Countries
If planning to drive in countries
outside the U.S. or Canada, the
proper fuel might be hard to find.
Check regional auto club or fuel
retail brand websites for availability
in the country where driving. Never
use leaded gasoline, fuel containing
methanol, manganese, or any other
fuel not recommended. Costly
repairs caused by use of improper
fuel would not be covered by the
vehicle warranty.
Fuel Additives
To keep fuel systems clean, TOP
TIER Detergent Gasoline is
recommended. See Fuel on
page 9-51.
If TOP TIER Detergent Gasoline is
not available, one bottle of Fuel
System Treatment PLUS added to
the fuel tank at every engine oil
change, can help. Fuel System
Treatment PLUS is the only gasoline additive recommended by
General Motors. It is available at
your dealer.
Filling the Tank
{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
.To help avoid injuries to you
and others, read and follow
all the instructions on the fuel
pump island.
.Turn off the engine when
refueling.
.Keep sparks, flames, and
smoking materials away
from fuel.
.Do not leave the fuel pump
unattended.
.Do not reenter the vehicle
while pumping fuel.
