2005 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 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 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 coin or similar object into the slot on the
back of the transmitter and gently pry apart the
front and back.
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.

Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
The keyless access transmitter must be in the vehicle
for the ignition to work.
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.
1. With your foot on the brake pedal, press the
START button. When the engine begins cranking,
let go of the button. The idle speed will go down as
your engine gets warm.
If the battery in the keyless access transmitter is
weak, the DIC will display FOB BATTERY LOW.
You can still drive the vehicle. See “Battery
Replacement” underKeyless Access System
Operation on page 2-5for more information.
2. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again.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.
Stopping Your Engine
Move the shift lever to PARK (P) and press the ACC
button. If the shifter is not in PARK (P), the vehicle will
go into accessory mode and the DIC will display
SHIFT TO PARK. Once the shifter is moved to
PARK (P), the vehicle will turn off.
If the keyless access transmitter is not detected while
going to off, the DIC will display NO FOB – OFF
OR RUN?.
SeeDIC Warnings and Messages on page 3-64
for more information.

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 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 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 your battery or if your
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 GM dealer can prepare the
vehicle for inspection.

LOW OIL PRESSURE:If this message appears while
the engine is running, stop the engine and do not
operate it until the cause of low oil pressure is corrected.
Severe damage to the engine can result. A multiple
chime will sound when this message is displayed.
LOW VOLTAGE:This message will appear when the
electrical system is charging less than 10 volts or if
the battery has been drained. If this message appears
immediately after starting, it is possible that the
generator can still recharge the battery. The battery
should recharge while driving but may take a few hours
to do so. Consider using an auxiliary charger (be
sure to follow the manufacturer’s instructions) to boost
the battery after returning home or to a nal destination.
If this message appears while driving or after starting
your vehicle and stays on, have it checked immediately
by your GM dealer to determine the cause of this
problem. To help the generator recharge the battery
quickly, you can reduce the load on the electrical system
by turning off the accessories. You can monitor battery
voltage on the DIC by pressing the INFO button.
The normal range is 11.5 to 15.5 volts.
LOW WASHER FLUID:This message means that your
vehicle is low on windshield washer uid. See
Windshield Washer Fluid on page 6-32.MAX SPEED XX MPH (XX KM/H):A failure in the
magnetic ride control system has occurred when this
message appears. The Powertrain Control Module
(PCM) determines the speed to which your vehicle is
limited. Have your vehicle serviced by your GM dealer if
this message appears.
NO FOB DETECTED:This message is displayed 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, such as two-way radios or
power inverters, is causing interference. Try moving
the keyless access transmitter away from these
devices when starting the vehicle.
The vehicle is experiencing Electro-Magnetic
Interference (EMI). Some locations, such as airports
or 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.
