2006 CADILLAC STS key fob battery

If you have additional transmitters to program, this
process can be repeated until 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 unlock button on each keyless access transmitter
twice. After performing this process, transmitters
previously programmed will no longer work with your
vehicle and must be reprogrammed.
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. The DIC
may display KEY FOB BATTERY LOW.
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 center
console storage area transmitter pocket with the buttons
facing to the front of the vehicle. Then, with the vehicle in
PARK (P) or NEUTRAL (N), press the brake pedal and
the start button. SeeStarting the Engine on page 2-25,
for additional information about your vehicle’s electronic
keyless ignition with push button start.Although this will start the vehicle, it is recommended that
you replace the transmitter battery as soon as possible.
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.
To replace the battery, do the following:
1. Insert a coin or similar object into the slot on the
back of the transmitter and carefully pry apart the
front and back.
2. Carefully pull the battery out of the transmitter.

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 located on the instrument panel. If there is not
a keyless access transmitter present or if there is
something causing interference with it, the DIC will
display NO FOB DETECTED. SeeDIC Warnings
and Messages on page 3-79for more information.
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.
Notice:Holding the button in for longer than
15 seconds at a time will cause the vehicle’s battery
to be drained much sooner. This can also cause
damage to the starter motor. Wait 15 seconds
between each try to avoid draining your vehicle’s
battery or damaging the starter.
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. 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
button located on the instrument panel. If the shifter is
not in PARK (P), the vehicle will go into the accessory
mode, the engine will turn off and the DIC will display
SHIFT TO PARK. When the shifter is moved to
PARK (P), the vehicle will go into the RAP mode, if
all doors are closed. The ignition mode will change to
OFF, if a front door is opened. SeeRetained Accessory
Power (RAP) on page 2-25for more information.
If the keyless access transmitter is not detected while
going to off, the DIC will display NO FOB – OFF
OR RUN?

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 2-24. 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 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.
Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
