ZR1 FEB suspension equipped
vehicles can be lowered 12 mm in
the front for optimal track
performance. Lowering the vehicle
should be completed prior to the
track suspension alignment. The
front spring outboard ends must be
unloaded from the front control arms
in order to adjust the spring cushion
adjuster screws upward by
approximately 6–9 mm to achieve
the lowered condition. Driving on
the public roads in this condition is
not recommended.
Caution
Failure to unload the front spring
outboard ends before adjusting
the spring cushion adjuster
screws could damage the spring.If the vehicle is a Z51, Grand Sport,
Z06, or ZR1, the racing and
competitive driving wheel alignment
settings should be set as
described here:
.
Z51 Performance
Package –remove one washer
from each upper control arm to
body bolt attachment (both front
and rear).
. Grand Sport, Z06, and
ZR1 models –do not remove
washers from front or rear upper
control arm bolts.
Proceed by adjusting the lower
control arm cam bolts until
alignment is within specifications.
Alignment values are targets. See
your dealer for tolerances.
After track use, reinstall washers
and reset to factory alignment
settings.

Rear Axle Fluid
Caution
During a first time track or racing
event, high rear axle
temperatures can occur. Damage
could be caused to the rear 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.
Axles must have 2414 km (1,500 mi)
before being used in track driving.
The rear axle fluid temperatures
may be higher than when driving in
severe conditions. Drain and refill
with new fluid after the first racing or
competitive driving event, and then

Starting and
Operating
New Vehicle Break-In
Follow these recommended
guidelines during the first 2 414 km
(1,500 mi) of driving this vehicle.
Parts have a break-in period and
performance will be better in the
long run.
For the first 322 km (200 mi):
.To break in new tires, drive at
moderate speeds and avoid hard
cornering.
. New brake linings also need a
break-in period. Avoid making
hard stops. This is
recommended every time brake
linings are replaced.
For the first 800 km (500 mi):
. Avoid full throttle starts and
abrupt stops.
. Do not exceed 4000 rpm. .
Avoid driving at any one
constant speed, fast or slow,
including the use of cruise
control.
. Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.
. Do not let the engine labor.
Never lug the engine. With a
manual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
. If equipped with a dry sump
engine (Stingray with Z51,
Grand Sport, and Z06), the initial
oil and filter change must be
performed at 800 km (500 mi).
For the first 2 414 km (1,500 mi):
. Do not participate in track
events, sport driving schools,
or similar activities.
. Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal.
Front Air Dam
If equipped, the front air dam has
minimal ground clearance.
Under normal operation, the
components will occasionally
contact some road surfaces (speed
bumps, driveway ramps, etc.). This
can be heard inside the vehicle as a
scraping noise. This is normal and
does not indicate a problem.
Use care when approaching bumps
or objects on road surfaces and
avoid them when possible.
Composite Materials
This vehicle may be equipped with
parts containing carbon fiber,
sheet-molding compound, or other
composite materials.
Dealer-installed accessories may
also contain composite materials.
These parts and accessories may
include the splitter or rocker
extensions.

Driver Mode Selector Attributes
Affected
Instrument Cluster Display
Configures the gauge cluster
display for each mode when linked
(default):
.Tour: Modern theme which
features displays for audio and
navigation.
. Sport: Classic easy to read
Sports Car gauges.
. Track: Gauges design based on
Corvette Racing display with lap

Throttle Progression
Adjusts throttle sensitivity by
selecting how quickly or slowly the
throttle reacts to input.
For ZR1 automatics, some
customers may hear a clicking noise
or feel a detent when pressing the
accelerator pedal all the way down
to the end of travel. This is normal
operation. The accelerator pedal
has a wide open throttle detent
button which provides the customer with a tactile feedback when they
have reached full accelerator pedal
travel. Depressing the pedal through
the detent button provides driver
feedback of an upcoming vehicle
downshift in normal driving
conditions. The detent feedback
window is reduced while operating
in Performance Algorithm Liftfoot
(PAL) or Performance Algorithm
Shift (PAS).
Transmission Shift Mode
−Paddle
Shift Automatic
. Adjusts to either a smoother or
firmer shift.
. Sport –Performance Algorithm
Liftfoot (PAL) recognizes
aggressive throttle maneuvers
and holds lower gears for
greater engine braking and
enhanced vehicle control when
not using paddles. (Available in
Sport or Track Mode.)
. Track –Performance Algorithm
Shift (PAS) recognizes
aggressive cornering, heavy braking, and high acceleration to
select and hold lower gears
when not using paddles.
Active Fuel Management (except
ZR1) (engine cylinder shuts off)
4-Cylinder Mode
. Normal with automatic
transmission: The engine uses
8-cylinder mode when
accelerating, but changes to
4-cylinder mode when coasting.
. With manual transmission:
Active Fuel Management only
active in Eco Mode.
. Off in Manual Mode with
automatic transmission unless in
Eco Mode.
. Eco keeps the engine in
4-cylinder mode unless heavy
acceleration is needed.
Exhaust (variable mode exhaust
system)
Changes when the variable exhaust
valves open.

Steering (Assist Effort)
Adjusts from a lighter steering feel
to reduced assist for more
steering feel.
Magnetic Ride Control (if
equipped)
Adjusts the shock dampening
firmness based on driving
conditions to improve comfort and
performance.
Launch Control
Available only in Track Mode for
maximum“off-the-line” acceleration
when in Competitive or PTM modes.
Stability Control
. Competitive Driving Mode allows
less computer control to permit
some slide and drift and is
selected with
g–only available
in Sport or Track Mode.
. StabiliTrak/ESC can be turned
off by pressing and holding
gfor
10 seconds. PTM (Performance Traction
Management) (if equipped)
.
Available in Track Mode.
. There are five selectable
settings if Competitive Driving
Mode is activated.
Competitive Driving Mode
If equipped, Competitive Driving
Mode, Performance Traction
Management, and Launch Control
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 System
(TCS) and StabiliTrak/Electronic
Stability Control (ESC) system 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
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.
Launch Control is available if in
Track Mode. Adjust your driving
style to account for the available
engine power. See “Launch Control”
later in this section.
