2007 CHEVROLET CORVETTE battery replacement

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.

Power Windows
The power window
switches are located
on each door.
Pull up on the front of the switch to raise the
window. Press down on the front of the switch
to lower the window.
Your vehicle has Retained Accessory Power
(RAP) that allows you to use the power windows
when the ignition is off. For more information,
seeRetained Accessory Power (RAP) on page 91.
Express-Down Window
This feature is on both power windows. Press
the front of the switch to the second position to
activate the express-down feature. If you want to
stop the window as it is lowering, press the
switch again.
Window Indexing
This feature automatically lowers the window a
small amount when the door is opened. Then, when
the door is closed, the window will raise to its full up
position. If either window does not index properly,
it could be due to loss of power. Before returning to
your dealer for service, perform the power window
initialize procedure following.
Power Window Initialize
After a power reconnect such as battery
replacement, the window index-up feature will
not function until the system is initialized. Once
power is restored, do the following:
1. Close the door.
2. Raise the window by pulling up the switch.
3. Hold the up switch for three seconds after the
window is closed. Release the switch.
4. Hold the up switch again for three seconds
and release.

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.

Replacing Brake System Parts
The braking system on a vehicle is complex.
Its many parts have to be of top quality and work
well together if the vehicle is to have really good
braking. Your vehicle was designed and tested
with top-quality brake parts. When you replace
parts of the braking system — for example, when
the brake linings wear down and you need new
ones put in — be sure you get new approved
replacement parts. If you do not, the brakes might
not work properly. For example, if someone puts
in brake linings that are wrong for your vehicle,
the balance between the front and rear brakes can
change — for the worse. The braking performance
you have come to expect can change in many other
ways if someone puts in the wrong replacement
brake parts.
Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that
has the replacement number shown on the
original battery’s label. We recommend an
ACDelco
®replacement battery.For battery replacement, see your dealer or the
service manual. To purchase a service manual,
seeService and Owner PublicationsinService
Publications Ordering Information on page 468.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
Vehicle Storage
If you are not going to drive your vehicle for
25 days or more, remove the black, negative (−)
cable from the battery. This will help keep
your battery from running down.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. SeeJump
Starting on page 365for tips on working
around a battery without getting hurt.
