2. Install the two closeout platesover the holes.
Install the two deflectors over
the holes, with the shorter one
in front.
3. Torque all the fasteners to 9Y (6.6 lb ft).
When the track event is complete,
remove the closeout plates and
deflectors and store them for the
next track event.
Rear Adjustable Performance
Wing (If Equipped)
The Rear Adjustable Performance
Wing can be adjusted up for greater
downforce during a track event.
To change the angle of the rear
wing, remove the rear attaching
bolts and move them to the upper
hole. Tighten the bolts to 9 Y
(6.6 lb ft). Return the wing to the
factory location following the track
event. Every time the wing is
adjusted, re-apply threadlocker to
the attachment bolts. See
Recommended Fluids and
Lubricants 0321.
Front Compartment Air
Deflector Panel
Prior to the track event, when
ambient temperatures are above 27
°C (80 °F), the panel between the
front fascia extension and the front
cradle can be removed to maximize
cooling air flow to the steering gear
power assist motor.
To remove the air deflector:
1. Remove the four front (2) and
three rear (4) front
compartment air deflector
screws.

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.

Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (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
may be heard while this test is going
on, and it may 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
0 117. 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.

. Sport: Classic easy to read
Sports Car gauges.
. Track: Gauges design based on

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.

Limited-Slip Differential
(Stingray without
Z51 Only)
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.
SeeCompetitive Driving Mode
0 203 andMaintenance Schedule
0 312.
Limited-Slip Differential
(ZR1, Z06, Grand Sport,
and Stingray with Z51)
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/ESC
For vehicles with eLSD, driven
under severe conditions, the rear
axle fluid should be changed.
See Competitive Driving Mode
0 203 andMaintenance Schedule
0 312.
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.

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 0237. .
Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil (Except
ZR1, Z06, Grand Sport, and
Stingray with Z51)
If the ENGINE OIL LOW–ADD OIL
message displays on the Driver
Information Center (DIC), check the
engine oil level right away.
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
0225 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.
