2008 CADILLAC XLR key fob battery

If you have additional transmitters to program, take
transmitter 1 out of the transmitter pocket and place
transmitter 2 in the pocket. This can be done repeatedly
until up to four transmitters have been programmed.
The DIC will then display MAX # FOBS LEARNED and
will exit the programming mode.
When you are done programming transmitters, press
the Acc. button.
Battery Replacement
Under normal use, the battery in your keyless access
transmitter should last about three years.
You can tell 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 FOB DETECTED when you try to start the vehicle.
If this happens, place the transmitter in the glove box
transmitter pocket with the buttons facing to the right.
Then, with the vehicle in PARK (P) or NEUTRAL (N),
press the brake pedal 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 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.

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 you vehicle, do the following:
Starting Procedure
1. With your foot on the brake pedal, press the
START button located on the instrument panel.
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 3-63for 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 KEY 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 3-63.3. 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 2-23. 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.

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.
NO FOB, OFF OR RUN?
This message displays when a keyless access
transmitter is not detected inside the vehicle while you
are trying to turn the ignition off. Your vehicle may be
near a strong radio antenna signal causing the keyless
access system to be jammed. The vehicle will remain in
ACCESSORY until the vehicle is turned off or is restarted,
or ve minutes has expired. If you turn the ignition off and
you cannot nd the keyless access transmitter, you will
not be able to restart the vehicle. The keyless access
transmitter needs to be inside of the vehicle in order for
the vehicle to start. SeeStarting the Engine on page 2-24
for more information.
OVER SPEED WARNING
This message displays when the vehicle speed exceeds
a certain limit as required by some export countries.
A chime sounds when this message is displayed.
PRESS BRAKE TO START
This message displays to inform you that the brake
pedal must be applied to start the vehicle. Make sure
you are pressing the brake pedal all the way down.
