9-12 Driving and Operating
Blizzard Conditions
Being stuck in snow can be in a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program (United States
and Canada) on page 13‑8 or
Roadside Assistance Program
(Mexico) on page 13‑10. To get
help and keep everyone in the
vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
Carbon Monoxide (CO) which
(Continued)
WARNING (Continued)
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets
on or under the instrument
panel.(Continued)
WARNING (Continued)
.Adjust the climate control
system to a setting that
circulates the air inside
the vehicle and set the fan
speed to the highest setting.
See Climate Control System
in the Index.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑26.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (Carbon
Monoxide) gas to get inside.
CO could overcome you and kill
you. You cannot see it or smell it,
so you might not know it is in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust.

Driving and Operating 9-19
For the first 80 km (500 miles):
.Avoid full throttle starts and
abrupt stops.
.Do not exceed 4,000 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 in high
gear at low speeds. With a
manual transmission, shift to
the next lower gear. This rule
applies at all times, not just
during the break-in period.For the first 2 414 km (1,500 miles):
.Do not participate in track
events, sport driving schools,
or similar activities during the
first 2 414 km (1,500 miles).
.Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 414 km (1,500 miles).
Front Air Dam
The vehicle is equipped with a front
air dam which has minimal ground
clearance.
Vehicles with the ZR-1 package,
or Z‐06 vehicles with RPO ULZ,
also come with a splitter made from
carbon fiber.
{WARNING
ZR‐1s, and Z‐06s with RPO ULZ,
contain parts made from carbon
fiber.
(Continued)
WARNING (Continued)
When damaged, the exposed
edges can be very sharp.
A person could be injured
by these sharp edges. Use
caution when washing the
vehicle, coming in contact with,
or removing damaged carbon
fiber parts. See your dealer for
replacement.
Under normal operation, these
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.

Black plate (23,1)Chevrolet Corvette Owner Manual - 2011
Driving and Operating 9-23
Notice:Cranking the engine for
long periods of time, by pressing
the START button immediately
after cranking has ended, can
overheat and damage the
cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
The vehicle has a
Computer-Controlled
Cranking System. This feature
assists in starting the engine
and protects components.
Once cranking has been initiated,
the engine continues cranking
for a few seconds or until the vehicle
starts. If the engine does not start,
cranking automatically stops after
15 seconds to prevent cranking
motor damage. To prevent gear
damage, this system also prevents
cranking if the engine is already
running. Notice:
The engine is designed
to work with the electronics in
the vehicle. If electrical parts
or accessories are added, you
could change the way the engine
operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.
Stopping the Engine
If the vehicle has an automatic
transmission, move the shift lever
to P (Park) and press and hold the
Acc. (Off/Accessory) button, located
on the instrument panel, until the
engine shuts off. If the shift lever
is not in P (Park), the engine shuts off and the vehicle goes into the
Accessory Mode. The DIC displays
SHIFT TO PARK. Once the shifter is
moved to P (Park), the vehicle turns
off. If the vehicle has a manual
transmission, it is recommended
that you move the shift lever to
R (Reverse) and set the parking
brake after you turn off the engine
by pressing and holding the Acc.
(Off/Accessory) button.
If the keyless access transmitter is
not detected inside the vehicle when
it is turned to off, the DIC displays
NO FOB
–OFF OR RUN?.
See Key and Lock Messages on
page 5‑42 for more information.

9-34 Driving and Operating
Downshifting
(Manual Transmission)
Do not downshift into the gear
shown below at a speed greater
than shown in the table:1 (First) 80 km/h (50 mph)
2 (Second) 119 km/h (74 mph)
3 (Third) 163 km/h
(101 mph)
4 (Fourth) 209 km/h
(130 mph)
Notice: If you skip more than one
gear when you downshift, or if
you race the engine when you
release the clutch pedal while
downshifting, you could damage
the engine, clutch, driveshaft or
the transmission. Do not skip
gears or race the engine when
downshifting. The six-speed transmission has
a spring that centers the shift
lever near 3 (Third) and 4 (Fourth).
This spring helps you know which
gear you are in when you are
shifting. Be careful when shifting
from 1 (First) to 2 (Second) or
downshifting from 6 (Sixth) to
5 (Fifth). The spring will try to pull
the shift lever toward 4 (Fourth) and
3 (Third). Make sure you move the
lever into 2 (Second) or 5 (Fifth).
If you let the shift lever move in the
direction of the pulling, you may end
up shifting from 1 (First) to 4 (Fourth)
or from 6 (Sixth) to 3 (Third).
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock
Brake System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and
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. See
Antilock
Brake System (ABS) Warning Light
on page 5‑22.

Black plate (49,1)Chevrolet Corvette Owner Manual - 2011
Driving and Operating 9-49
If the vehicle has the 6.2L V8 engine
(VIN Code T) or the 7.0L V8 engine
(VIN Code E), use premium
unleaded gasoline with a posted
octane rating of 91 or higher.
For best performance, use premium
unleaded gasoline with a posted
octane rating of 93. In an
emergency, you can use regular
unleaded gasoline with an octane
rating of 87 or higher. If 87 octane
fuel is used, do not perform any
aggressive driving maneuvers such
as wide open throttle applications.
You might also hear audible spark
knock during acceleration. Refill the
tank with premium fuel as soon as
possible to avoid damaging the
engine. If heavy knocking is heard
when using gasoline rated at
91 octane or higher, the engine
needs service.Gasoline Specifications
At a minimum, gasoline
should meet ASTM specification
D 4814 in the United States or
CAN/CGSB‐3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeFuel Additives
on page 9‑50 for additional
information.
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 might fail a smog‐check test.
See
Malfunction Indicator Lamp on
page 5‑18. 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 might not be covered by the
vehicle warranty.
Fuels in Foreign
Countries
If you plan on driving in another
country outside the United States or
Canada, the proper fuel might be
hard to find. Never use leaded
gasoline or any other fuel not
recommended in the previous text
on fuel. Costly repairs caused by
use of improper fuel would not be
covered by the vehicle warranty.
To check the fuel availability, ask
an auto club, or contact a major oil
company that does business in the
country where you will be driving.

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:
.Always use engine oil approved
to the proper specification and
of the proper viscosity grade.
See “Selecting the Right
Engine Oil.”
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil.”
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10‑22.
.Always dispose of engine oil
properly. See “What to Do With
Used Oil.”

Checking Engine Oil (Except
ZO6, ZR1, and Grand Sport)
If the CHECK OIL LEVEL message
displays on the Driver Information
Center (DIC), check the engine
oil level right away. For more
information, seeEngine Oil
Messages on page 5‑40. Check
the engine oil level regularly;
this is an added reminder.
It is a good idea to check the engine
oil level at each fuel fill. In order
to get an accurate reading, the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. See Engine
Compartment Overview on
page 10‑10 for the location
of the engine oil dipstick. Obtaining an accurate oil level
reading is essential:
1. If the engine has been running
recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking your oil level too soon
after engine shut off will not
provide an accurate oil level
reading.
2. Pull the dipstick and clean it with a paper towel or cloth, then push
it back in all the way. Remove it
again, keeping the tip down, and
check the level.
When to Add Engine Oil
(Except ZO6, ZR1, and Grand
Sport)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
one liter/quart of the recommended
oil and then recheck the level.
See “Selecting the Right Engine Oil”
for an explanation of what kind of
oil to use. For engine oil crankcase
capacity, see Capacities and
Specifications on page 12‑2.
