Stingray without Z51 Performance
Package: Additional oil fill above the
upper mark on the dipstick is not
recommended for track events or
other competitive driving. Check the
oil level often during racing or other
competitive driving and keep the
level at or near the upper mark that
shows the proper operating range
on the engine oil dipstick. After the
competitive driving, remove excess
oil so that the level on the dipstick is
not above the upper mark that
shows the proper operating range.
Fuel
LT1 Engine :93 octane (or higher)
unleaded gasoline is required.
LT4 Engine : 93 octane (or higher)
unleaded gasoline is required.
100 octane (or higher) unleaded
gasoline is recommended at the
track when temperatures are above
30 °C (86 °F) to maximize
powertrain performance and
improve longevity of components
within the powertrain. LT5 Engine :
93 octane (or higher)
unleaded gasoline is required.
100 octane (or higher) unleaded
gasoline is recommended to
maximize powertrain performance
and improve longevity of
components within the powertrain.
Caution
Some high octane fuels contain
additives and compounds that
may damage the vehicle and void
the vehicle warranty. See
Prohibited Fuels 0213.
Automatic Transmission Fluid
Transmission fluid should be
changed after every 15 hours of
track usage. Any transmission level
set or change should be performed
at your dealer.
Manual Transmission Fluid
Manual transmission fluid should be
changed after every 15 hours of
track usage.
Load Limit
Z51 Performance Package Only:
Limit vehicle load to the driver only,
with no other cargo. Inflate tires to

after every 24 hours of racing or
competitive driving. See
Recommended Fluids and
Lubricants0321.
General Information
If reduced performance is
experienced during track events or
competitive driving, turning off the
A/C will help to improve engine
performance.
Maintain a mixture of 40%
DEX-COOL coolant and 60% clean,
drinkable water to optimize engine
performance.
The front license plate bracket or
aero panel should be removed for
track events and competitive driving
to improve engine performance.
Brakes
{Warning
Braking above 200 mph:
(Continued)
Warning (Continued)
Applying and sustaining full force
braking at speeds exceeding
200 mph (322 km/h) can cause
serious damage to the braking
system. At any speed, braking
must be performed in a smooth
and controlled manner, but at
these speeds specifically, lower
initial brake pedal efforts are
recommended.
Brake Cooling
If additional brake cooling is
required, the grille mesh in the lower
corners of the front grille in front of
the brake duct can be removed.
This is not reversible, and a
replacement grille will not be
covered by the vehicle warranty.
If this is done, it is recommended
that the gap between the fascia and
the cooling duct be taped over. Brake Fluid
Replace existing brake fluid with a
qualified high performance brake
fluid from a sealed container. Brake
fluid with a dry boiling point >310 °C
(590 °F) is qualified. If high
performance brake fluid is used,
replace it with GM approved brake
fluid before driving on public roads.
If high performance brake fluid is in
the vehicle and the age of the brake
fluid is over a month old or
unknown, replace the brake fluid
before track events and competitive
driving. Do not use silicone or
DOT-5 brake fluids.
Brake Burnishing
New brake pads must be burnished
before racing or other competitive
driving.
Caution
Performing the brake burnish
procedure on a base brake
system can result in brake
damage.

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.

182 Driving and Operating
Starting the Engine
Place the transmission in the
proper gear.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
SeeAdd-On Electrical Equipment
0 216.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). To restart the vehicle
when it is already moving, use
N (Neutral) only.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped. Manual Transmission
The shift lever should be in Neutral
and the parking brake engaged.
Hold the clutch pedal down to the
floor, press the brake pedal, and
start the engine.
Starting the Vehicle
The RKE transmitter must be inside
the vehicle for the ignition to work.
Cell phone chargers can interfere
with the operation of the Keyless
Access system. Battery chargers
should not be plugged in when
starting or turning off the engine.
1. For vehicles with an automatic transmission, press the brake
pedal, then press ENGINE
START/STOP on the
instrument panel. For vehicles
with a manual transmission,
hold the clutch pedal down to
the floor, press the brake pedal
and then press ENGINE
START/STOP.
If there is no RKE transmitter in
the vehicle or if there is
something causing interference with it, the Driver Information
Center (DIC) will display a
message.
2. When the engine begins cranking, let go of the button
and the engine cranks
automatically until it starts.
If the battery in the RKE
transmitter is weak, the DIC will
display a message. The vehicle
can still be driven.
See “Starting the Vehicle with a
Low Transmitter Battery” under
Remote Keyless Entry (RKE)
System Operation 027. If the
RKE transmitter battery is
dead, insert it into the steering
column transmitter pocket to
enable engine starting.
3. Do not race the engine immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.

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.
(Continued)
Warning (Continued)
.Do not leave the fuel pump
unattended.
. Avoid using electronic
devices while refueling.
. Do not reenter the vehicle
while pumping fuel.
. Keep children away from
the fuel pump and never let
children pump fuel.
. Fuel can spray out if the
refueling nozzle is inserted
too quickly. This spray can
happen if the tank is nearly
full, and is more likely in hot
weather. Insert the refueling
nozzle slowly and wait for
any hiss noise to stop prior
to beginning to flow fuel.
To open the fuel door, push and
release the rearward center edge of
the door. The fuel door is locked
when the vehicle doors are locked.
Press
Kon the RKE transmitter to
unlock. The driver door must be
opened before the fuel door will
unlock.
The vehicle has a capless refueling
system and does not have a fuel
cap. The filling nozzle must be fully
inserted and latched prior to starting
fuel flow.
