9-22 Driving and Operating
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.
To start the vehicle, do the following:
1. For vehicles with an automatictransmission, with your foot
on the brake pedal, press the
START button located on the
instrument panel. For vehicles
with a manual transmission, you
must also press in the clutch
pedal while pressing the START
button.
If there is not a keyless access
transmitter in the vehicle or if
there is something causing
interference with it, the DIC will
display NO FOBS DETECTED.
See Key and Lock Messages on
page 5‑42 for more information. 2. When the engine begins
cranking, let go of the button and
the engine cranks automatically
until it starts. If the battery in the
keyless access transmitter is
weak, the DIC displays FOB
BATTERY LOW. You can still
drive the vehicle.
See “Battery Replacement”
under Remote Keyless Entry
(RKE) System Operation on
page 2‑3 for more information.
If the fob battery is dead, you
need to insert the fob into
the fob slot to enable engine
starting. See “NO FOBS
DETECTED” underKey and
Lock Messages on page 5‑42.
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. 4. If the engine does not start and
no DIC message is displayed,
wait 15 seconds before trying
again to let the cranking motor
cool down.
If the engine does not start after
5-10 seconds, especially in very
cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor while cranking for up
to 15 seconds maximum. Wait at
least 15 seconds between each
try, to allow the cranking motor
to cool down. When the engine
starts, let go of the accelerator.
If the vehicle starts briefly but
then stops again, repeat these
steps. This clears the extra
gasoline from the engine.

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.

Black plate (50,1)Chevrolet Corvette Owner Manual - 2011
9-50 Driving and Operating
Fuel Additives
To provide cleaner air, all gasolines
in the United States are now
required to contain additives
that help prevent engine and fuel
system deposits from forming,
allowing the emission control
system to work properly. In most
cases, nothing should have to be
added to the fuel. However, some
gasolines contain only the minimum
amount of additive required to meet
U.S. Environmental Protection
Agency regulations. To help keep
fuel injectors and intake valves
clean, or if the vehicle experiences
problems due to dirty injectors or
valves, look for gasoline that is
advertised as TOP TIER Detergent
Gasoline. Look for the TOP TIER
label on the fuel pump to ensure
gasoline meets enhanced
detergency standards developed
by the auto companies. A list of
marketers providing TOP TIER
Detergent Gasoline can be found
at www.toptiergas.com.For customers who do not use
TOP TIER Detergent Gasoline
regularly, one bottle of GM Fuel
System Treatment PLUS, added
to the fuel tank at every engine oil
change, can help clean deposits
from fuel injectors and intake
valves. GM Fuel System Treatment
PLUS is the only gasoline additive
recommended by General Motors.
It is available at your dealer.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might
be available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
10% ethanol must not be used in
vehicles that were not designed for
those fuels.
Notice:
This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
the life of spark plugs and the
performance of the emission
control system could be affected.
The malfunction indicator lamp
might turn on. If this occurs, return
to your dealer for service.
