Engine Exhaust
{WARNING
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
.The vehicle idles in areas
with poor ventilation (parking
garages, tunnels, deep snow
that may block underbody
airflow or tail pipes).
.The exhaust smells or
sounds strange or different.
.The exhaust system leaks
due to corrosion or damage.
.The vehicle exhaust system
has been modified, damaged,
or improperly repaired.(Continued)
WARNING (Continued)
.There are holes or openings
in the vehicle body from
damage or aftermarket
modifications that are not
completely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle:
.Drive it only with the windows
completely down.
.Have the vehicle repaired
immediately.
Never park the vehicle with the
engine running in an enclosed
area such as a garage or a
building that has no fresh air
ventilation.
Running the Vehicle
While Parked
It is better not to park with the
engine running.
If the vehicle is left with the engine
running, follow the proper steps to
be sure the vehicle will not move.
See Shifting Into Park (Automatic
Transmission) on page 9‑22 and
Engine Exhaust on page 9‑24. If the
vehicle has a manual transmission,
see Parking (Manual Transmission)
on page 9‑23.

Driving and Operating 9-25
Automatic
Transmission
There are several different positions
for the shift lever.
P (Park):This position locks the
rear wheels. It is the best position to
use when starting the engine
because the vehicle cannot move
easily.
{WARNING
It is 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.
Do not leave the vehicle when the
engine is running. 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,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park (Automatic
Transmission) on page 9‑22.
Be sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. You have to fully apply the
brakes and then press the shift lever
button before you can shift from
P (Park) when the vehicle is running. If you cannot shift out of
P (Park), ease pressure on the shift
lever and push the shift lever all the
way into P (Park) as you maintain
brake application. Then press the
shift lever button and move the shift
lever into another gear. See
Shifting
out of Park on page 9‑23.
R (Reverse): Use this gear to
back up.
Notice: Shifting to R (Reverse)
while the vehicle is moving
forward could damage the
transmission. The repairs would
not be covered by the vehicle
warranty. Shift to R (Reverse) only
after the vehicle is stopped.
To rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the transmission, see If
the Vehicle Is Stuck on page 9‑12.

9-26 Driving and Operating
N (Neutral):In this position, the
engine does not connect with the
wheels. To restart the engine when
the vehicle is already moving, use
N (Neutral) only. If the vehicle needs
towing, see Towing the Vehicle on
page 10‑79.
{WARNING
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Notice: Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle. D (Drive):
This position is for
normal driving. It provides the best
fuel economy. If you need more
power for passing, push the pedal
down to achieve the desired level of
acceleration.
Downshifting the transmission in
slippery road conditions could result
in skidding. See “Skidding”under
Loss of Control on page 9‑5.
S (Sport Mode): When in
S (Sport Mode), the transmission will
work as an automatic until you use
the Manual Paddle Shift Controls,
which activates driver manual gear
selection. See Manual Mode on
page 9‑26. While in S (Sport Mode),
the transmission will have more
noticeable upshifts for sportier
vehicle performance.
Manual Mode
Manual Paddle Shift
While in S (Sport Mode), the paddles
located on the steering wheel can
be used to manually up-shift or
down-shift the transmission.
The Manual Paddle Shift system is
activated from S (Sport Mode) by
pushing the paddle, above the
steering wheel spokes, to up-shift to
the next gear, or pulling on the
paddle, behind the steering wheel
spokes, to down-shift to the
next gear.

Black plate (27,1)Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12
Driving and Operating 9-27
When accelerating the vehicle from
a stop in snowy and icy conditions,
you may want to shift to 2 (Second)
or 3 (Third) gear. A higher gear
allows you to gain more traction on
slippery surfaces. If traction control
is active, upshifts are delayed to
increase your control of the vehicle.
SeeTraction Control System (TCS)
on page 9‑34 Traction Control
System (TCS).
The Manual Paddle Shift system
can be deactivated by moving the
shift lever from S (Sport Mode) back
to D (Drive), or by holding either
up-shift paddle for more than
one second.
The driver may choose to briefly
activate the Manual Paddle Shift
system while in D (Drive). Tapping
either the upshift or downshift
controls will place the transmission
in Manual Paddle Shift mode. The
driver may then exit Manual Paddle
Shift mode by holding either upshift
control for more than one second.
The system will return to automatic
shifting after 10 seconds of cruising at a steady speed and no manual
shifts, or when the vehicle comes to
a stop.
While the Manual Paddle Shift gear
selection system is active, the
transmission will automatically
downshift through the gears as the
vehicle slows. The transmission will
select 2 (Second) gear as the
vehicle stops. From a stop, the
vehicle will start from and hold
2 (Second) gear unless the driver
manually paddle shifts into a
different gear or selects D (Drive).
The driver can select 1 (First) gear
for maximum acceleration from
a stop.
When using the Manual Paddle
Shift feature while in S (Sport Mode),
the current gear will be displayed in
the Driver Information (DIC), or the
Head-Up Display (HUD), if the
vehicle has either of these features.
If the vehicle has a Head-Up
Display (HUD), see
Head-Up
Display (HUD) on page 5‑30.
The Manual Paddle Shift system will
not allow either an up-shift or a
down-shift if the vehicle speed is too
fast or too slow, nor will it allow a
start from 4 (Fourth) or higher gear.
If up-shifting does not occur when
needed, vehicle speed will be
limited to protect the engine.
When the transmission gear does
not respond to a shift change, the
DIC will show an X over the gear
display.

spinning with a loss of traction, it
is possible to cause damage to
the transmission. Do not attempt
to shift when the drive wheels do
not have traction. Damage caused
by misuse of the vehicle is not
covered. See the warranty book
for additional information.
Adding non-dealer accessories can
affect the vehicle's performance.
See Accessories and Modifications
on page 10‑3 for more information.Active Handling System
The Active Handling System is a
computer controlled system that
helps the driver maintain directional
control of the vehicle in difficult
driving conditions. This is
accomplished by selectively
applying any one of the vehicle's
brakes.
The ACTIVE HANDLING message
will come on when the system is
operating. See Ride Control System
Messages on page 5‑42 for more
information. The system may be
heard or felt while it is working. This
is normal.
The SERVICE ACTIVE HANDLING
SYSTEM message is displayed on
the DIC, the Active Handling System light comes on, and a sound
is heard if there is a problem with
the system.
See
Ride Control System Messages
on page 5‑42 for more information.
When this light and the SERVICE
ACTIVE HANDLING SYSTEM
message are on, the system is not
operational. Adjust your driving
accordingly.
The Active Handling System comes
on automatically whenever the
vehicle is started. To help maintain
directional control of the vehicle, the
system should always be left on.
The system can be turned off if
needed. If the Active Handling
System is turned off, the Traction
Control System will also be turned
off. Adjust your driving accordingly.

.The Active Handling System will
feel different in aiding and
maintaining directional control.
Competitive Driving Mode
Competitive Driving Mode,
Performance Traction Management,
and Launch Control are systems
designed to allow increasedperformance while accelerating and/
or cornering. This is accomplished
by regulating and optimizing the
engine, brakes, and suspension
performance. These modes are for
use at a closed course race track
and are not intended for use on
public roads. They will not
compensate for driver inexperience
or lack of familiarity with the race
track. Drivers who prefer to allow
the system to have more control of
the engine, brake, and suspension
are advised to turn the normal
traction control and active handling
systems on. See
Racing or Other
Competitive Driving on page 9‑6.
Notice: Do not attempt to shift
when the drive wheels are
spinning and do not have
traction. This may cause damage
to the transmission. Damage
caused by misuse of the vehicle
is not covered by the vehicle
warranty. See the warranty book
for additional information.
