2008 CHEVROLET CORVETTE key fob battery

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 3-57
for 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 2-6for 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” underDIC Warnings and
Messages on page 3-57.3. 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 pedal all 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.

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might 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 2-22. 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 press the
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/retailer can prepare the vehicle for inspection.

NO FOBS DETECTED
This message displays if the vehicle does not detect the
presence of a keyless access transmitter when you
have attempted to start the vehicle or a vehicle door has
just closed. The following conditions may cause this
message to appear:
Driver-added equipment plugged into the accessory
power outlet on the center console is causing
interference. Examples of these devices are cell
phones and cell phone chargers, two-way radios,
power inverters, or similar items. Try moving
the keyless access transmitter away from these
devices when starting the vehicle. In addition,
PDA devices and remote garage and gate openers
may also generate Electromagnetic Interference
(EMI) that may interfere with the keyless access
transmitter. Do not carry the keyless access
transmitter in the same pocket or bag as these
devices.
The vehicle is experiencing Electromagnetic
Interference (EMI). Some locations, such as
airports, automatic toll booths, and some gas
stations have EMI elds which may interfere with
the keyless access transmitter.If moving the transmitter to different locations within
the vehicle does not help, place the transmitter in the
glove box transmitter pocket with the buttons facing to
the right and then press the START button.
The vehicle’s battery voltage is low. The battery
voltage must be above 10 volts for the keyless
access transmitter to be detected properly.
