2007 CHEVROLET CORVETTE key battery

If you ever notice a decrease in the keyless
access transmitter range, try doing one of the
following:
Check the distance. You may be too far from
your vehicle. You may need to stand closer
during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps to
the left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement
is necessary. See “Battery Replacement” under
Keyless Access System Operation on page 73.
Check to make sure that an electronic device
such as a cellular phone or lap top computer is
not causing interference.
If you are still having trouble, see your dealer/
retailer or a qualied technician for service.
Keyless Access System Operation
Your vehicle has a keyless access system
that allows you to lock and unlock your doors,
unlock your hatch/trunk lid and disarm or arm
your theft-deterrent system. The range distance
is as much as 100 feet (30 m) away.
Your vehicle comes standard with two transmitters,
and up to four can be matched to your vehicle. See
“Matching Transmitter(s) to Your Vehicle” later in
this section.
Q(Lock):Press this button to lock the doors.
The light on the door will ash once. If this button
is pressed two times, the doors will lock, the
light will ash and the horn will sound.

Battery Replacement
Under normal use, the battery in your keyless
access transmitter should last about three years.
The battery is weak if the transmitter will not
work at the normal range in any location. If you
have to get close to your vehicle before the
transmitter works, it is probably time to change
the battery.
A weak battery may also cause the DIC to display
NO FOBS DETECTED when you try to start the
vehicle. If this happens, place the transmitter in
the glove box transmitter pocket with the buttons
facing towards the passenger’s side. Then, with the
vehicle in PARK (P) for an automatic transmission,
press the brake pedal and the START button. If
your vehicle has a manual transmission, press
the clutch and the START button. Although this
will start the vehicle, it is recommended that you
replace the transmitter battery as soon as possible.
The DIC may display FOB BATTERY LOW.
Notice:When replacing the battery, use
care not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.1. Insert a at object with a thin edge into the
slot on the side or back of the transmitter
and separate the bottom half from the top half.
2. Gently pull the battery out of the transmitter.
3. Put the new battery in the transmitter,
positive (+) side down. Use a battery,
type CR2032, or equivalent.
4. Reassemble the transmitter. Make sure to put
it together so water will not get in.
5. Test the transmitter.

If your vehicle has lost battery power, open the
hatch/trunk using the vehicle key. SeeKeys
on page 71for more information. The key lock
cylinder is located on the rear of the hatch/trunk lid
above the license plate. Turn the vehicle key
clockwise in the lock.
Closing the Rear Compartment (Coupe)
To assist in closing the rear compartment lid
of your coupe, use the pocket on the underside
of the lid on the passenger’s side of the vehicle.
When closing the lid, lower it until the power
pull down latch feature activates and it will close
the rest of the way and latch automatically.
Emergency Trunk Release Handle
(Convertible Only)
Notice:Do not use the emergency trunk
release handle as a tie-down or anchor point
when securing items in the trunk as it could
damage the handle. The emergency trunk
release handle is only intended to aid a person
trapped in a latched trunk, enabling them to
open the trunk from the inside.

Arming the System
To arm the system:
Press the lock button on the keyless access
transmitter.
Open the door. Lock the door with the power
door lock switch. The security light should ash.
Remove the keyless access transmitter from
inside the vehicle and close the door. The
security light will stop ashing and stay on.
After 30 seconds, the light should turn off.
The vehicle can be programmed to
automatically lock the doors and arm the
theft-deterrent system when you exit the
vehicle. SeeDIC Vehicle Personalization
on page 234.
Now, if a door or the hatch/trunk is opened without
the keyless access transmitter, the alarm will go off.
Your horn will sound for two minutes, then it will go
off to save battery power. Your vehicle will not start
without a keyless access transmitter present.
The theft-deterrent system will not arm if you
lock the driver’s door with the power door
lock switch after the doors are closed.If your passenger stays in the vehicle when you
leave with the keyless access transmitter, have the
passenger lock the vehicle after the doors are
closed. This way the alarm will not arm, and
your passenger will not set it off.Testing the Alarm
To test the system:
1. Make sure the trunk lid/hatch is latched.
2. Lower the window on the driver’s door.
3. Manually arm the system.
4. Close the doors and wait 30 seconds.
5. Reach through the open window and manually
pull the release lever on the oor.
6. Turn off the alarm by pressing the unlock
button on the transmitter.
If the alarm is inoperative, check to see if the horn
works. If not, check the horn fuse. SeeFuses and
Circuit Breakers on page 419. If the horn works, but
the alarm doesn’t go off, see your dealer/retailer.

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.

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.

the day, this knob will adjust the instrument panel
brightness and at night will adjust all interior
lighting.
Be sure not to have this knob turned all the way
down with the lamps on during the day. Your
Driver Information Center (DIC) may not be visible.
Courtesy Lamps
When any door or the hatch/trunk lid is opened,
the interior lamps will go on unless it is bright
outside.
You can also turn the courtesy lamps on and off
by pressing the instrument panel brightness knob.
Entry/Exit Lighting
With entry lighting, the interior lamps will come on
when entering the vehicle. The interior lamps
will come on for about 20 seconds when the
engine is off.
You can turn exit and entry lighting off by quickly
turning the courtesy lamps on and off.
Reading Lamps
The inside rearview mirror includes two reading
lamps. The lamps will go on when a door is
opened. When the doors are closed, each lamp
can be turned on individually by pressing the
switch for that lamp.
An ambient light is located in the passenger sun
visor clip. This light stays on while driving to
keep the cabin from being too dark.
Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained in case any of
the following lamps are left on; the underhood
lamp, if your vehicle has this feature, vanity mirror
lamps, cargo lamps, reading lamps, console or
glove box lamps. If any of these lamps are left on,
they will automatically time-out after about
10 minutes. To reset it, all of the above lamps
must be turned off or the ignition key on.

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is in
the passenger compartment. SeeIgnition Positions
on page 90. Press the bottom of the Acc. button on
the instrument panel and hold the button down for
ve seconds. The instrument panel, including the
check engine light, will light up and the ignition will
be on, but the engine will not start — if you pressthe bottom of the Acc. button only briey, less than
ve seconds, the accessory power mode will be
turned on, but not the ignition. After the bulb check,
be sure to press and release the Acc. button again
to turn the ignition off and avoid draining the
vehicle’s battery.
Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if you have recently replaced
the battery or if the battery has run down.
The diagnostic system is designed to evaluate
critical emission control systems during normal
driving. This may take several days of routine
driving. If you have done this and your vehicle
still does not pass the inspection for lack of
OBD system readiness, your dealer can prepare
the vehicle for inspection.
