2007 CHEVROLET CORVETTE automatic transmission

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 PARK (P) if
your vehicle is moving. If you do, you could
damage the transmission. Shift to PARK (P)
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.
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 214for more
information.
91

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 73for 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” under
DIC Warnings and Messages on page 214.
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 pedalall 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.
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.
92

Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.
Stopping Your Engine
If your vehicle has an automatic transmission,
move the shift lever to PARK (P) and press the
Acc. (Off/Accessory) button located on the
instrument panel. 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 214for
more information.
Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged
in a minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use
of the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.

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.
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 (P) (Automatic
Transmission) on page 103.
Be sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transmission shift lock control system.
95

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. See
Shifting Out of Park (P) (Automatic Transmission)
on page 104.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage
the transmission. The repairs would not
be covered by your warranty. Shift to
REVERSE (R) only after your 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 308.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 315.
{CAUTION:
Shifting into a drive gear while your
engine is running at high speed is
dangerous. Unless your foot is rmly on
the brake pedal, your vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while your engine is running at
high speed.
Notice:Shifting out of PARK (P) or
NEUTRAL (N) with the engine running at high
speed may damage the transmission. The
repairs would not be covered by your warranty.
Be sure the engine is not running at high speed
when shifting your vehicle.
96

DRIVE (D):This position is for normal driving.
It provide 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 291.
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.
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.
97

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 and icy 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 281.
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.
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.
98

Shifting Into Park (P)
(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 102for 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 your vehicle
with the engine running. Your vehicle could
move suddenly if the shift lever is not fully
in PARK (P) 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 your 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).
