CHEVROLET CORVETTE 2007 6.G Owners Manual

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.

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 195for more information.
101

Downshifting (Manual Transmission)
Do not downshift into the gear shown below
at a speed greater than shown in the table:
FIRST (1) 50 mph (80 km/h)
SECOND (2) 74 mph (119 km/h)
THIRD (3) 101 mph (163 km/h)
FOURTH (4) 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 THIRD (3) and
FOURTH (4). This spring helps you know which
gear you are in when you are shifting. Be careful
when shifting from FIRST (1) to SECOND (2)
or downshifting from SIXTH (6) to FIFTH (5).The spring will try to pull the shift lever toward
FOURTH (4) and THIRD (3). Make sure you move
the lever into SECOND (2) or FIFTH (5). If you let
the shift lever move in the direction of the pulling,
you may end up shifting from FIRST (1) to
FOURTH (4) or from SIXTH (6) to THIRD (3).
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. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
102

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).
103

Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift your
transmission into PARK (P) 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 PARK (P). This is called
“torque lock.” To prevent torque lock, set the
parking brake and then shift into PARK (P) properly
before you leave the driver’s seat. To nd out how,
see “Shifting Into PARK (P)” listed previously in this
section.
When you are ready to drive, move the shift lever
out of PARK (P) 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 PARK (P).
Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift
lock control system which locks the shift lever
in PARK (P) when the ignition is off. In addition,
you have to fully apply your regular brake
before you can shift from PARK (P) when the
ignition is on. SeeAutomatic Transmission
Operation on page 95.
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) and release the shift lever
button as you maintain brake application.
Then press the shift lever button and move
the shift lever into the gear you wish.
104

If you ever hold the brake pedal down but still
cannot shift out of PARK (P), try this:
1. Press the regular brake.
2. Press the Acc. button twice to place the
ignition in accessory mode. SeeIgnition
Positions on page 90for more information.
3. Apply and hold the brake until the end of
Step 4.
4. Shift to NEUTRAL (N).
5. Start the engine and then shift to the drive
gear you want.
6. Have your vehicle inspected by your
dealer/retailer as soon as possible.
Parking Your Vehicle
(Manual Transmission)
Before you get out of your vehicle, move the shift
lever into REVERSE (R) and rmly apply the
parking brake. Once the shift lever has been
placed into REVERSE (R) with the clutch pedal
pressed in, you can turn the ignition off and
release the clutch.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
105

Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the
gas carbon monoxide (CO), which you
cannot see or smell. It can cause
unconsciousness and death.
You might have exhaust coming in if:
The exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a
collision.
CAUTION: (Continued)
CAUTION: (Continued)

Your vehicle was damaged when
driving over high points on the road
or over road debris.
Repairs were not done correctly.
Your vehicle or the exhaust system
has been modied improperly.
If you ever suspect exhaust is coming into
your vehicle:
Drive it only with all the windows
down to blow out any CO; and
Have your vehicle xed immediately.
106

Running the Engine 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 the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 106.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is
at the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park
in a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 304.
{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. 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 the parking brake and move
the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P)
(Automatic Transmission) on page 103.

Mirrors
Manual Rearview Mirror
When you are sitting in a comfortable driving
position, adjust the mirror so you can see clearly
behind your vehicle. Grip the mirror in the center to
move it up or down and side to side. The day/night
control, located at the bottom of the mirror, lessens
glare from the headlamps behind your vehicle when
in the night position. Turn the control to the right for
the night position and to the left for the day position.
Two buttons under the rearview mirror control
map lamps. Push each button to turn each map
lamp on or off.
Automatic Dimming Rearview Mirror
with OnStar
®and Compass
The vehicle may have an automatic dimming
rearview mirror with OnStar®, a compass and map
lamps. Three OnStar®buttons are at the bottom
of the mirror. SeeOnStar®System on page 114
for more information on the services OnStar®
provides.
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. The automatic
dimming feature is turned on or off by pressing this
button located on the lower part of the mirror. Press
and hold the button for up to three seconds to turn
this feature on or off.
T(Indicator Light):This light will turn on when
the automatic dimming feature is active.
Map Lamps
The mirror has map lamps located at the bottom
of the mirror. To manually turn the lamps on or off,
press the button next to each lamp.
108

Compass Operation
The mirror has an eight-point compass display in
the bottom of the mirror face.
When the ignition and the compass feature are
on, the compass will show two character boxes for
approximately two seconds. After two seconds,
the mirror will display the current compass
heading. For example, NE is displayed for
north-east.
Compass Calibration
If after two seconds the display does not show a
compass heading, there may be a strong magnetic
eld interfering with the compass. Such interference
may be caused by a magnetic antenna mount, note
pad holder or similar object. If the letter C appears
in the compass window, the compass needs
calibration.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.
The compass can be placed in calibration
mode by pressing and holding the left map light
button until a C appears on the compass display.
Compass Variance
Compass variance is the difference between
earth’s magnetic north and true geographic
north. If the mirror is not adjusted for compass
variance, your compass could give false readings.
The mirror is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if you live
outside zone eight. Under certain circumstances,
such as a long distance, cross-country trip, it
will be necessary to adjust the compass variance.
109

To adjust for compass variance, do the following:
1. Find your current location and variance
zone number on the zone map that follows.
2. Press and hold the on/off button untilaZand
a zone number appears on the display. The
compass is now in zone mode.3. Once the zone number appears on the display,
press the on/off button quickly until you reach
the correct zone number. Stop pressing the
button and the mirror will return to normal
operation. If C appears in the compass
window, the compass may need calibration.
See “Compass Calibration” listed previously.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or
similar material dampened with glass cleaner.
Do not spray glass cleaner directly on the mirror
as that may cause the liquid cleaner to enter
the mirror housing.
Automatic Dimming Rearview
Mirror with Compass
If the vehicle has this feature, an automatic
dimming mirror automatically dims to the proper
level to minimize glare at night from lights
behind your vehicle.
The mirror also includes a compass display in
the upper right corner of the mirror face.
P(On/Off):This is the on/off button.
