2007 CADILLAC XLR key fob battery

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 up. 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.

To start you vehicle, do the following:
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 FOB DETECTED. SeeDIC Warnings and
Messages on page 206for 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 68for 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 206.3. 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.
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
be stops after 15 seconds to prevent cranking
motor damage. To prevent gear damage,
this system also prevents cranking if the engine is
already running.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.Stopping Your Engine
Move the shift lever to PARK (P) and press the
Acc. (Off/Accessory) button located on the
instrument panel. If the shifter is not in PARK (P),
the engine shuts off and the vehicle goes into
the Accessory Mode. The DIC displays″SHIFT TO
PARK″. Once the shifter is moved to PARK (P),
the vehicle turns off.
If the keyless access transmitter is not detected
inside the vehicle when it is turned to off, the DIC
displays NO FOB – OFF OR RUN?.
SeeDIC Warnings and Messages on page 206for
more information.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 366. Poor fuel
quality will cause the engine not to run as
efficiently as designed. You may notice this as
stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is
warmed up.) This will be detected by the system
and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.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 88. 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.

NO FOB 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 your 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.
