N (Neutral):In this position, the
engine does not connect with the
wheels. To restart the engine when
the vehicle is already moving, use
N (Neutral) only. If the vehicle needs
towing, see Towing the Vehicle on
page 10-83.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
{Caution
Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may

damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
D (Drive): This position is for
normal driving. It provides the best
fuel economy. If more power is
needed for passing, push the pedal
down to achieve the desired level of
acceleration.
Downshifting the transmission in
slippery road conditions could result
in skidding. See “Skidding”under
Loss of Control on page 9-4.
The transmission can be shifted like
a manual transmission using the
paddle shift controls while in
D (Drive). See Manual Mode on
page 9-29.
M (Manual Mode): In
M (Manual Mode), the transmission
can be shifted like a manual transmission using the paddle shift
controls. See
Manual Mode on
page 9-29.
Manual Mode
Manual Paddle Shift
When the shift lever is moved to
M (Manual Mode), the transmission
enters Manual Mode. The
transmission will hold the current
gear until a change is requested.
The paddles on the steering wheel
can be used to manually upshift or

Brakes
Antilock Brake
System (ABS)
This vehicle has ABS, an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
might be heard while this test is
going on, and it might even be
noticed that the brake pedal moves
a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5-22. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses the wheels are
slowing down. If one of the wheels
is about to stop rolling, the computer
will separately work the brakes at
each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You may hear the ABS
pump or motor operating and feel
the brake pedal pulsate. This is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.

more firmly, and re-apply the
accelerator 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
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 (except Z51 and Z06
with Magnetic Ride Control) or
Performance Traction Management
(Z51 and Z06 with Magnetic 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 and Z06)
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. For
vehicles with limited slip differential,
driven under severe conditions, the
rear axle fluid should be changed.
See Competitive Driving Mode on
page 9-44 andMaintenance
Schedule on page 11-2.
Limited-Slip Differential
(Z51 and Z06 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.
For vehicles with limited slip
differential, driven under severe
conditions, the rear axle fluid should
be changed. See Competitive
Driving Mode on page 9-44 and
Maintenance Schedule on
page 11-2.

Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more
can be maintained without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If equipped with a manual
transmission, the cruise control will
remain active when the gears are shifted. The cruise is disengaged if
the clutch is pressed for several
seconds.
If the Traction Control System (TCS)
begins to limit wheel spin while you
are using cruise control, the cruise
control automatically disengages.
See
Traction Control/Electronic
Stability Control on page 9-38.
When road conditions allow for
using safely again, cruise control
can be turned back on.
If the brakes are applied, cruise
control disengages.
1(On/Off): Press to turn cruise
control on or off. A white indicator
comes on in the instrument cluster
when cruise is turned on.
RES/+ (Resume/Accelerate): If
there is a set speed in memory,
press briefly to resume to that
speed or press and hold to
accelerate. If cruise control is
already active, use to increase
vehicle speed.
SET/– (Set/Coast): Press briefly to
set the speed and activate cruise
control. If cruise control is already
active, use to decrease vehicle
speed.
*(Cancel): Press to disengage
cruise control without erasing the
set speed from memory.

Vehicle Care 10-31
Rear
FrontZ06 models with the Z07 package
have an electronic brake pad wear
sensor system. When pads are
worn, the CHANGE BRAKE PADS
message displays in the Driver
Information Center (DIC). See
Brake
System Messages on page 5-34.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Brake linings should always be
replaced as complete axle sets.
Brake Rotor Wear
Z06 models may have ceramic
brake rotors. Visually inspect rotors
whenever the brake pads are
replaced. Weigh rotors before brake
pads are replaced to confirm that
the rotor mass is greater than the
wear-out mass printed on the rotor.
The rotor can be reused if the
weight of the rotor is above the
mass limit. See the service manual for rotor inspection and weighing
methods. See
Service Publications
Ordering Information on page 13-11.
Brake Rotor Protector
{Warning
Ceramic rotors will be very hot
after operation and touching them
may cause burns. Be sure brake
system is completely cool prior to
installation of protector, or coming
in contact with them.
{Caution
Rotors may be chipped if hard
contact is made with the wheel
during wheel installation or
removal. Always use the rotor
protectors. Follow the wheel
removal and installation
instructions.

10-32 Vehicle Care
A rotor protector should always be
installed before any wheel removal.
Install the protector by feeding itthrough the wheel spokes and
slipping it over the outer edge of the
rotor. Leave the protector in place,
over the rotor edge, until the wheel
is reinstalled. Rotor protectors are
available through your dealer.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement
parts. If this is not done, the brakes
may not work properly. The braking
performance expected can change
in many other ways if the wrong
replacement brake parts are
installed or parts are improperly
installed.
Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid. See
Engine Compartment Overview on
page 10-7
for the location of the
reservoir.
There are only two reasons why the
brake fluid level in the reservoir
might go down:
.The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.
.A fluid leak in the brake
hydraulic system can also cause
a low fluid level. Have the brake
hydraulic system fixed, since a
leak means that sooner or later
the brakes will not work well.

Vehicle Care 10-49
If using winter tires:
.Use tires of the same brand and
tread type on all four wheel
positions.
.Use only radial ply tires of the
same size, load range, and
speed rating as the original
equipment tires.
Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W, Y,
and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.
Run-Flat Tires
This vehicle, when new, had run-flat
tires. There is no spare tire, no tire
changing equipment, and no place
to store a tire in the vehicle.
The vehicle also has a Tire
Pressure Monitor System (TPMS)
that indicates a loss of tire pressure
in any of the tires.
{Warning
If the low tire warning light
displays on the instrument cluster,
the handling capabilities will be
reduced during severe
maneuvers. Driving too fast could
cause loss of control and you or
others could be injured. Do not
drive over 80 km/h (50 mph) when
the low tire warning light is
displayed. Drive cautiously and
check the tire pressures as soon
as possible.
Run-flat tires can be driven on with
no air pressure. There is no need to
stop on the side of the road to
change the tire. Continue driving;
however, do not drive too far or too
fast. Driving on the tire may not be
possible if there is permanent
damage. To prevent permanent
damage, the tire can be driven with
no air pressure for up to 80 km
(50 mi) at speeds slower than
80 km/h (50 mph). As soon as possible, contact the nearest
authorized GM or run-flat servicing
facility for inspection and repair or
replacement.
When driving on a deflated run-flat
tire, avoid potholes and other road
hazards that could damage the tire
and/or wheel beyond repair. When a
tire has been damaged, or if driven
any distance while deflated, check
with an authorized run-flat tire
service center to determine whether
the tire can be repaired or should be
replaced. To maintain the run-flat
feature, all replacement tires must
be run-flat tires.
To locate the nearest GM or run-flat
servicing facility, call Customer
Assistance.
The valve stems on run-flat tires
have sensors that are part of the
TPMS. See
Tire Pressure Monitor
System on page 10-59. These
sensors contain batteries that are
designed to last for 10 years under

alignment. SeeWhen It Is Time
for New Tires on page 10-63
and Wheel Replacement on
page 10-68.
Different tire sizes should not be
rotated front to rear.
Use this rotation pattern if the
vehicle has different size tires
on the front and rear.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after the tires have been rotated. See
Tire Pressure on page 10-57
and
Vehicle Load Limits on
page 9-15.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10-60.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications on
page 12-2.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
(Continued)
Warning (Continued)
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
When It Is Time for New
Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
