2008 CADILLAC STS battery replacement

Keyless Access System
Your vehicle has a Keyless Access System that
operates on a radio frequency subject to Federal
Communications Commission (FCC) Rules and with
Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.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 2-6.
Check to make sure that an electronic device such

Battery Replacement
Under normal use, the battery in your keyless access
transmitter should last about three years.
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 2-29, 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:
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. Carefully 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 inside the transmitter.
5. Test the transmitter.

Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
20 minutes after the engine is turned off:
Audio System
Audio Steering Wheel Controls
Power Windows
Power to these accessories will work up to 20 minutes
or until one of the front doors is opened. For an
additional 20 minutes of operation, close all the doors
and press Acc. to place the vehicle in accessory mode.
Press the button again to return to RAP.
Starting the Engine
To place the transmission in the proper gear:
Move the shift lever to PARK (P) or NEUTRAL (N).
To restart when you are already moving, use
NEUTRAL (N).
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.
The keyless access transmitter must be inside the
vehicle for the ignition to work.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 your 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 3-80for 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 3-80.
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.

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 brake parts.
When you replace parts of the braking system — for
example, when the brake linings wear down and you
need new ones put in — be sure you get new approved
replacement parts. If you do not, the brakes might not
work properly. For example, if someone puts in brake
linings that are wrong for your vehicle, the balance
between the 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, see your dealer/retailer
for one that has the replacement number shown on
the original battery’s label. SeeEngine Compartment
Overview on page 5-11for battery location.
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
{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 5-45for tips on working around a battery
without getting hurt.
Infrequent Usage: If you drive your vehicle infrequently,
remove the black, negative (−) cable from the battery.
This will help keep the battery from running down.
Extended Storage: For extended storage of your vehicle,
remove the black, negative (−) cable from the battery
or use a battery trickle charger. This will help maintain
the charge of the battery over an extended period
of time.

Vehicle Identication
Vehicle Identication Number (VIN)
This is the legal identier for your vehicle. It appears
on a plate in the front corner of the instrument panel,
on the driver side. You can see it if you look through the
windshield from outside your vehicle. The VIN also
appears on the Vehicle Certication and Service Parts
labels and the certicates of title and registration.
Engine Identication
The eighth character in the VIN is the engine code.
This code helps you identify your vehicle’s engine,
specications, and replacement parts.
Service Parts Identication Label
This label is on the spare tire cover. It is very helpful if
you ever need to order parts. The label has the
following information:
Vehicle Identication Number (VIN)
Model designation
Paint information
Production options and special equipment
Do not remove this label from the vehicle.
Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer/retailer
rst. Some electrical equipment can damage your
vehicle and the damage would not be covered by
your warranty. Some add-on electrical equipment can
keep other components from working as they should.
Add-on equipment can drain your vehicle’s battery, even
if your vehicle is not operating.
Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-64.
