Driving and Operating 9-11
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they 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. Always have the
engine running and the vehicle in
gear when going downhill.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in
your own lane.
.Be alert on top of hills,
something could be in your
lane (stalled car, accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C
(32°F) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
The
Antilock Brake System (ABS)
on page 9‑35 improves vehicle
stability during hard stops on
slippery roads, but apply the brakes
sooner than when on dry pavement.
Allow greater following distance on
any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
Turn off cruise control on slippery
surfaces.

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.
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.
(Continued)
WARNING (Continued)
.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.
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.

Driving and Operating 9-13
WARNING (Continued)
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.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart the vehicle and to signal for
help with the headlamps. Do this as
little as possible to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 55 km/h (35 mph).
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑80.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a forward
gear, or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out,
see Towing the Vehicle on
page 10‑86.

New Vehicle Break-In
Follow these recommended
guidelines during the first 2 414 km
(1,500 miles) 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 miles):
.To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first 322 km
(200 miles).
.New brake linings also need a
break- in period. Avoid making
hard stops during the first
322 km (200 miles). This is
recommended every time brake
linings are replaced.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 ZR1 package,
or Z06 vehicles with RPO CFZ, also
come with a splitter made from
carbon fiber.

Black plate (19,1)Chevrolet Corvette Owner Manual - 2012
Driving and Operating 9-19
{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.
Ignition Positions
The vehicle has an electronic
keyless ignition with a push-button
start.
In order to shift out of P (Park),
the vehicle must be running or in
Acc. mode and the regular brake
pedal must be applied.
/(START): Press this button
while your foot is on the brake for
an automatic transmission, or while
pressing in the clutch for a manual
transmission, to start the engine.
If the vehicle is in OFF or Retained Accessory Power (RAP) mode, the
Remote Keyless Entry (RKE)
transmitter must be inside the
vehicle to start the engine.
9Acc. (STOPPING THE ENGINE/
OFF/ACCESSORY): When the
vehicle is stopped with the engine
on, press the button once to turn
the engine off.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in
an emergency:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to neutral. This can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location.

3. Come to a complete stop. Shiftto P (Park) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition to OFF.
4. Set the parking brake. See Parking Brake on page 9‑36
{WARNING
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
turn the ignition to ACC/
ACCESSORY. When the engine is on or the
vehicle is in accessory power mode,
it is recommended that a manual
transmission be placed in
R (Reverse). An automatic
transmission must be placed in
P (Park). Then press the Acc. button
to turn the engine off and place the
vehicle in RAP. See
Retained
Accessory Power (RAP) on
page 9‑23 for more information.
If an automatic vehicle is not
correctly placed in P (Park) a SHIFT
TO PARK message will display on
the Driver Information Center (DIC).
For more information, see
Transmission Messages on
page 5‑53.
When the engine is off, press this
button to place the vehicle in
accessory mode. ACCESSORY
MODE ON will display on the Driver
Information Center (DIC). This mode
allows you to use things like the
radio and the power windows while
the engine is off. Use accessory
mode if you must have the vehicle in motion while the engine is off, for
example, if the vehicle is being
pushed or towed.
After being in accessory mode for
about 10 minutes, the vehicle will
automatically enter RAP or OFF,
depending on if the doors are
opened or closed.
Service Only Mode
This power mode is available for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. With the vehicle off,
pressing and holding the bottom of
the button for more than
five seconds will place the vehicle in
Service Only Mode. The instruments
and audio systems will operate as
they do when the engine is running,
but the vehicle will not be able to be
driven. The engine will not start in
Service Only Mode. Push the button
again to turn the vehicle off.

Starting the Engine
Move the shift lever to P (Park) or
N (Neutral) for an automatic
transmission. For a manual
transmission the vehicle can be
started in Neutral or any other gear
as long as the clutch pedal is
pressed. To restart a vehicle with a
manual transmission when you are
already moving, use the Neutral
position only. To restart a vehicle
with an automatic transmission
when you are already moving, use
N (Neutral).
Notice: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.
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.
To start the vehicle, do the following:
1. For vehicles with an automatic
transmission, 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 an RKE 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 5‑43 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
RKE 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 5‑43.
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 andno 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.
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?.

{WARNING
It can be dangerous to get out of
the vehicle if the shift lever is not
fully in P (Park) with the parking
brake firmly set. The vehicle can
roll. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, use the steps
that follow. 1. Hold the brake pedal down and
set the parking brake. See
Parking Brake on page 9‑36 for
more information.
2. Move the shift lever into P (Park) by holding in the button on the
lever and pushing the lever all
the way toward the front of the
vehicle.
3. Press the Acc. button (ignition switch) to turn the engine off.

Leaving the Vehicle with
the Engine Running
(Automatic Transmission)
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
firmly set. And, if you leave the
vehicle with the engine running, it
could overheat and even catch
fire. You or others could be
injured. Do not leave the vehicle
with the engine running.If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved
the shift lever into P (Park), hold
down the regular brake pedal. See if
you can move the shift lever away
from P (Park) without first pushing
the button on the lever. If you can, it
means that the shift lever was not
fully locked into P (Park).
Torque Lock (Automatic
Transmission)
If you are parking on a hill and you
do not shift the transmission into
P (Park) properly, the weight of
the vehicle may put too much
force on the parking pawl in the
transmission. You may find it difficult
to pull the shift lever out of P (Park). This is called
“torque lock.”
To prevent torque lock, set the
parking brake and then shift into
P (Park) properly before you leave
the driver seat. To find out how, see
“Shifting Into P (Park)” previously in
this section.
When you are ready to drive, move
the shift lever out of P (Park) before
you release the parking brake.
If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of
the pressure from the transmission
parking pawl, so you can pull the
shift lever out of P (Park).
