2008 Chevrolet Corvette Owner ManualM

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

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.

Shift Speeds (Manual Transmission)
{CAUTION:
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Do not shift down
more than one gear at a time when you
downshift.
This chart shows when to shift to the next higher gear
for the best fuel economy.
Manual Transmission Recommended
Shift Speeds in mph (km/h)
EngineAcceleration Shift Speed
1to2 2to3 3to4 4to5 5to6
All
Engines15 (24) 25 (40) 40 (64) 45 (72) 50 (80)If your engine speed drops below 900 rpm, or if the
engine is not running smoothly, you should downshift to
the next lower gear. You may have to downshift two
or more gears to keep the engine running smoothly or
for good engine performance.
Notice:When shifting gears, do not move the shift
lever around unnecessarily. This may damage
the transmission. Shift directly into the next gear.
One to Four Shift Light
(Manual Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
SeeOne-to-Four Shift Light (Manual Transmission) on
page 3-40for more information.

Manual Paddle Shift Gear Indicator (If Equipped)
These displays on the HUD are for use when
using the manual paddle shift controls to shift
the transmission. See “Manual Paddle Shift” in
Automatic Transmission Operation on page 2-26.
Shift Light
This light is used for performance driving to indicate
that the vehicle’s best performance level has
been reached to shift the transmission into the next
higher gear. An arrow pointing up will light up on
the display just prior to reaching the engine fuel
cut-off mode. This cut-off is about 6,500 RPM for
the LS3 engine and 7,000 RPM for the LS7 engine.

x9w(Fan):Press the button with the fan symbol
to manually increase or decrease the fan speed.
Keep pressing the up or down arrow on this switch until
the desired fan speed appears on the display.
Pressing the arrows will delete AUTO from the digital
display. The fan graphics with the fan speed bars will be
shown. To increase the fan speed so that more air
ows into the vehicle, press the up arrow on the
fan switch. To decrease the fan speed and airow,
press the down arrow. The AUTO button must be
pressed to return to the automatic fan control.
If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter
may need to be replaced. For more information,
seePassenger Compartment Air Filter on page 3-32
andScheduled Maintenance on page 6-4.
?(Recirculation):Press this button to turn the
recirculation mode on or off. When the climate control
system is in recirculation mode an indicator light will
come on. This mode prevents outside air from entering
your vehicle. It can be used to prevent outside air and
odors from entering your vehicle and to help cool the air
inside your vehicle more quickly. Recirculation mode is
not available in defrost or defog mode.
^(Air Conditioning Off):Press this button to turn the
air conditioning compressor off. Press AUTO to return
to automatic operation. When in AUTO, the air
conditioning compressor will come on automatically,
as needed.
Air conditioning does not operate at temperatures below
about 35°F to 40°F (2°C to 4°C). In temperatures
above 40°F (4°C), the air conditioning cannot be turned
off in defrost and defog, as it helps to remove moisture
from the vehicle. It also helps to keep the windows clear.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
