Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑54.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park the vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep the interior
temperature cool.
.Keep your eyes moving —scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.

Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
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
cannot be seen or smelled. It can
cause unconsciousness and even
death.
(Continued)
WARNING (Continued)
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.
.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.(Continued)
WARNING (Continued)
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.
Run the engine for short periods
only as needed to keep warm,
but be careful.

Driving and Operating 9-19
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 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 2414 km (1500 mi):
.Do not participate in track
events, sport driving schools,
or similar activities during the
first 2414 km (1500 mi).
.Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2414 km (1500 mi).
Front Air Dam
The vehicle is equipped with a front
air dam which has minimal ground
clearance.
Vehicles with the ZR1 package,
or Z06 vehicles with RPO CFZ,
also come with a splitter made from
carbon fiber.
{WARNING
ZR1s, and Z06s with RPO CFZ,
contain parts made from carbon
fiber.
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.

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.
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 RKE 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.

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. SeeAntilock
Brake System (ABS) Warning Light
on page 5‑22. 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 that 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
the driver 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 might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.

Black plate (49,1)Chevrolet Corvette Owner Manual - 2012
Driving and Operating 9-49
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
(U.S. and Canada Only)
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. See
Fuel 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 5‑19. 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
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.
