2006 CADILLAC STS battery replacement

If you ever notice a decrease in the keyless access
transmitter range, try doing one of the following:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the left
or right, hold the transmitter higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Keyless Access System Operation on page 2-5.
Check to make sure that an electronic device such
as a cellular phone or lap top computer is not causing
interference.
If you are still having trouble, see your dealer or a
qualied technician for service.
Keyless Access System Operation
Your vehicle has a Keyless Access System that lets
you lock and unlock your vehicle’s doors, open the trunk
lid, remotely start the engine, and locate your vehicle,
or sound your vehicle’s alarm from a distance as
much as much as 30 feet (10 m) away.The Keyless Access System also lets you lock and
unlock the vehicle’s doors and access the trunk without
removing the remote transmitter from your pocket,
purse, briefcase, etc. The system operates when the
transmitter is located within 3 feet (1 m) of the door
or trunk of your vehicle. See “Keyless Doors Unlock”
and “Keyless Ft (Front) Door Unlock” underVehicle
Personalization on page 2-53.
Your vehicle comes with
two transmitters.
Q(Lock):Press this button to lock the doors. The lock
status light on the front doors will turn on for ve seconds
and the turn signal indicators will ash. If this button is
pressed twice, the doors will lock, the status light on
the door will turn on for ve seconds, the turn signal
indicators will ash twice, and the horn will sound once.
2-5

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.
2-9

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?
SeeDIC Warnings and Messages on page 3-79for
more information.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality GM brake parts.
When you replace parts of your braking system — for
example, when your brake linings wear down and you
need new ones put in — be sure you get new approved
replacement parts. If you do not, your brakes may no
longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the balance
between your front and rear brakes can change — for the
worse. The braking performance you have come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.
Battery
Your vehicle has a maintenance free battery. When it is
time for a new battery, get one that has the replacement
number shown on the original battery’s label. We
recommend an ACDelco
®replacement battery. See
Engine Compartment Overview on page 5-12for battery
location and access.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
Vehicle Storage
If you are not going to drive your vehicle for 25 days
or more, remove the black, negative (−) cable from
the battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
are not careful. SeeJump Starting on page 5-45
for tips on working around a battery without
getting hurt.
