2009 CHEVROLET CORVETTE Owners Manual

Shift Speeds (Manual Transmission)
{CAUTION:
If you skip a gear when you downshift, you could
lose control of the 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)

All
Engines15 (24) 25 (40) 40 (64) 45 (72) 50 (80)If the 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
1 (First) to 4 (Fourth)
instead of 1 (First) to
2 (Second).
SeeOne-to-Four Shift Light (Manual Transmission) on
page 3-38for more information.

Downshifting (Manual Transmission)
Do not downshift into the gear shown below at a speed
greater than shown in the table:
1 (First) 50 mph (80 km/h)
2 (Second) 74 mph (119 km/h)
3 (Third) 101 mph (163 km/h)
4 (Fourth) 130 mph (209 km/h)
Notice:If you skip more than one gear when
you downshift, or if you race the engine when you
release the clutch pedal while downshifting, you
could damage the engine, clutch, driveshaft or the
transmission. Do not skip gears or race the engine
when downshifting.
The six-speed transmission has a spring that centers the
shift lever near 3 (Third) and 4 (Fourth). This spring helps
you know which gear you are in when you are shifting.
Be careful when shifting from 1 (First) to 2 (Second) or
downshifting from 6 (Sixth) to 5 (Fifth). The spring will try
to pull the shift lever toward 4 (Fourth) and 3 (Third).
Make sure you move the lever into 2 (Second) or
5 (Fifth). If you let the shift lever move in the direction
of the pulling, you may end up shifting from 1 (First) to
4 (Fourth) or from 6 (Sixth) to 3 (Third).
Parking Brake
The parking brake lever is located to the right of the
center console.
To set the parking brake, hold the brake pedal down.
Pull the parking brake lever up. If the ignition is on,
the brake system warning light will come on.
To release the parking brake, hold the brake pedal
down. Then push the release button in as you move
the parking brake lever all the way down.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.

Shifting Into Park
(Automatic Transmission)
{CAUTION:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake rmly 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 set the parking brake.
SeeParking Brake on page 2-32for 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)
{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 the vehicle with the engine running,
be sure the vehicle is in P (Park) and the parking brake is
rmly 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 rst pushing the button on the lever.
If you can, it means that the shift lever was not fully
locked into P (Park).
2-33

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 nd 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 nd out how, see “Shifting Into P (Park)”
listed 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).
Shifting Out of Park
Shift lock release prevents shifting out of P (Park)
unless the vehicle is running or in Accessory mode
and the brake pedal is applied.
The shift lock release is always functional except in
the case of an uncharged or low voltage (less than
9-volt) battery. SeeJump Starting on page 5-51
for more information.To shift out of P (Park) use the following:
1. Apply the brake pedal.
2. Press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park):
1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift
lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from P (Park),
consult your dealer/retailer or a professional towing
service.
Parking the Vehicle
(Manual Transmission)
Before you get out of the vehicle, move the shift lever
into R (Reverse) and rmly apply the parking brake.
Once the shift lever has been placed into R (Reverse)
with the clutch pedal pressed in, you can turn the ignition
off and release the clutch.

Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that
has no fresh air ventilation. For more information,
seeEngine Exhaust on page 2-35.
{CAUTION:
It can be dangerous to get out of the vehicle if
the automatic transmission shift lever is not fully

Mirrors
Automatic Dimming Rearview Mirror
The vehicle may have an automatic dimming inside
rearview mirror with a compass display and/or map
lamps, and OnStar
®. If the vehicle has OnStar, there are
three control buttons located at the bottom of the mirror.
SeeOnStar
®System on page 2-40for more information
on the services OnStar®provides.
Automatic Dimming Mirror Operation
The mirror automatically changes to reduce glare
from headlamps behind you. A time delay feature
prevents rapid changing from the day to night positions
while driving under lights and through traffic.
P(On/Off):The automatic dimming feature is activated
when the vehicle is started. Press and hold this button
for up to six seconds to turn this feature on or off.

off, press the button next to each lamp.
Cleaning the Mirror
Do not spray glass cleaner directly on the mirror.
Use a soft towel dampened with water.
Compass
Compass Operation
With the compass feature on, each time the vehicle
is started, the compass will take a few seconds to adjust
and display the current compass heading. For example,
NE is displayed for north-east.
2-37

Compass Calibration
PressPonce to turn the compass display on or off.
If after several seconds the display does not show
a compass heading, there may be a strong magnetic
eld interfering with the compass. Interference can
be caused by a magnetic antenna mount, note
pad holder or similar object. If the letter C or CAL
appears in the compass window, the compass needs
calibration.
Depending on the mirror, in order to calibrate, CAL must
be displayed in the mirror compass windows. If CAL is not
displayed, press
Pfor several seconds or until CAL is
displayed.
If the compass has map lamps, it can be placed in
calibration mode by pressing and holding the left map
light button until a C appears on the compass display.
The mirror compass can be calibrated by driving
the vehicle in circles at 5 mph (8 km/h) or less until
the display reads a direction.
Compass Variance
The mirror is set to zone eight. If you do not live in zone
eight or drive out of the area, the compass variance
needs to be changed to the appropriate zone.To adjust for compass variance:
1. Find your current location and variance zone
number on the zone map that follows.
2. Press and hold
Puntil a Z and a zone number
displays. The compass is now in zone mode.
