2008 CHEVROLET CORVETTE automatic transmission

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 windshield wipers while the engine is off. Use
accessory mode if you must have your vehicle in motion
while the engine is off, for example, if your 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.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
These features continue to work up to 10 minutes after
the engine is turned off or until either door is opened.
If a door is opened, the power windows and audio
system will shut off.
Starting the Engine
Move the shift lever to PARK (P) or NEUTRAL (N) for
an automatic transmission. For a manual transmission
the vehicle can be started in NEUTRAL or any other
gear as long as the clutch is depressed. To restart
a manual transmission when you are already moving,
use the NEUTRAL position only. To restart an automatic
transmission when you are already moving, use
NEUTRAL (N).
Notice:Do not try to shift to P (Park) if your vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when your
vehicle is stopped.
The keyless access 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.
2-23

To start your vehicle, do the following:
1. For an automatic transmission, with your foot on the
brake pedal, press the START button located on
the instrument panel. For a manual transmission,
while pressing in the clutch, press 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.
SeeDIC Warnings and Messages on page 3-57
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” underKeyless Access
System Operation on page 2-6for 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” underDIC Warnings and
Messages on page 3-57.3. 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 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
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 briey
but then stops again, do the same thing. 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.
2-24

Your 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/retailer. If you
do not, the engine might not perform properly.
Any resulting damage would not be covered by the
vehicle warranty.Stopping Your Engine
If your vehicle has an automatic transmission, move the
shift lever to PARK (P) 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
PARK (P), the engine shuts off and the vehicle goes
into the Accessory Mode. The DIC displays SHIFT TO
PARK. Once the shifter is moved to PARK (P), the
vehicle turns off. If your vehicle has a manual
transmission, it is recommended that you move the
shift lever to REVERSE (R) and set the parking
brake after you turn off the engine by pressing 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?.
SeeDIC Warnings and Messages on page 3-57for
more information.

Automatic Transmission Operation
There are several different
positions for your shift
lever.
PARK (P):This position locks your rear wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
CAUTION: (Continued)
CAUTION: (Continued)
Do not leave your vehicle when the engine is
running unless you have to. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move, even
when you are on fairly level ground, always set
your parking brake and move the shift lever to
PARK (P). SeeShifting Into Park (Automatic
Transmission) on page 2-33.
Be sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system.
You have to fully apply your regular brakes rst and
then press the shift lever button before you can
shift from PARK (P) when the vehicle is running. If you
cannot shift out of PARK (P), ease pressure on the
shift lever and push the shift lever all the way into
PARK (P) as you maintain brake application. Then press
the shift lever button and move the shift lever into
another gear. SeeShifting Out of Park on page 2-34.
2-26

REVERSE (R):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 your vehicle back and forth to get out of snow,
ice, or sand without damaging your transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-23.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. If your vehicle
needs towing, seeTowing Your Vehicle on page 4-29.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless
your foot is rmly 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.
DRIVE (D):This position is for normal driving.
It provides the best fuel economy for your vehicle.
If you need more power for passing, and you are:
Going less than about 35 mph (56 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (56 km/h) or more, push the
accelerator all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-13.
SPORT MODE (S):When in SPORT MODE (S), the
transmission will work as an automatic until you use the
Manual Paddle Shift Controls, which activates the
driver manual gear selection. See Manual Paddle Shift
later in this section. While in automatic SPORT
MODE (S), the transmission computer determines when
the vehicle is being driven in a competitive manner
and will select and hold the transmission in lower gears
and have more noticeable upshifts for sportier vehicle
performance.
2-27

Manual Paddle Shift
While in the SPORT MODE (S) position, the paddles
located on the steering wheel, can be used to manually
up-shift or down-shift the transmission.
While in the SPORT MODE (S) mode, push the paddle
above the steering wheel spokes to up-shift to the
next gear, or pull on the paddle behind the steering
wheel spokes to down-shift to the next gear.
To use the system, shift from PARK (P) position to
SPORT MODE (S) while stopped and with the engine
running, or from DRIVE (D) with the vehicle moving.
When accelerating your vehicle from a stop in snowy andicy conditions, you may want to shift to second (2) or
third (3) gear. A higher gear allows you to gain more
traction on slippery surfaces. If the traction control is
active, upshifts are delayed to increase your control of the
vehicle. SeeTraction Control System (TCS) on page 4-6.
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 second gear as the vehicle stops. From a stop,
the vehicle will start from and hold second (2) gear unless
the driver manually paddle shifts into a different gear or
selects DRIVE (D). The driver can select rst (1) gear for
maximum acceleration from a stop.
When using the Manual
Paddle Shift Feature while
in the SPORT MODE (S),
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 your vehicle has a Navigation system, see “Head-Up
Display (HUD)” in the Index of the navigation manual.
2-28

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 Fourth (4)
or higher gear
If up-shifting does not occur when needed, the vehicle
speed will be limited to protect the engine.
The transmission will also automatically down-shift as
the vehicle slows down and comes to a stop.
When the transmission gear does not respond to a shift
change, the DIC will show an X over the gear display.
When a requested shift is
denied due to the speed
restrictions shown, the DIC
will momentarily show
an X over the gear display
and a chime will sound.
If the vehicle has a HUD, and the transmission gear
does not respond to a shift change, then a chime
will sound and the HUD will momentarily show an X
over the gear display.Manual Paddle Shift operation is available for use with
Cruise Control, seeCruise Control on page 3-11for
more information.
The vehicle speeds required for Manual Paddle Shift
up-shifts depend on several vehicle inputs, which
will vary the allowed up-shift speed by a few mph (km/h).
Up-shifts to Fourth (4) gear require approximately
22 mph (35 km/h).
Up-shifts to Fifth (5) gear require approximately
28 mph (45 km/h).
Up-shifts to Sixth (6) gear require approximately
41 mph (65 km/h).
To prevent damage to the powertrain, Manual Paddle
downshifts to a lower gear cannot be done above certain
speeds. The maximum speed allowed for downshifting
of gears one (1) through fourth (4) are:
Into Fourth (4) gear over 168 mph (270 km/h)
Into Third (3) gear over 124 mph (200 km/h)
Into Second (2) gear over 81 mph (130 km/h)
Into First (1) gear over 45 mph (72 km/h).
If the driver does not request an upshift as the engine
speed approaches fuel shut off RPM, the engine
speed will be limited to protect the engine. See
Tachometer on page 3-36for more information.

Shifting Into Park
(Automatic Transmission)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when you are on fairly level
ground, use the steps that follow.
1. Hold the brake pedal down with your right foot and
set the parking brake.
SeeParking Brake on page 2-32for more
information.
2. Move the shift lever into PARK (P) 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 Your Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
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 rmly set. And,
if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
the vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold down
the regular brake pedal. See if you can move the
shift lever away from PARK (P) without rst pulling it
toward you. If you can, it means that the shift lever was
not fully locked into PARK (P).
