2008 CADILLAC XLR battery

A thick layer of additional material, such as a blanket or
cushion, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers can affect
how well the passenger sensing system operates.
We recommend that you not use seat covers or other
aftermarket equipment other than any that GM has
approved for your specic vehicle. SeeAdding
Equipment to Your Airbag-Equipped Vehicle on
page 1-51for more information about modications that
can affect how the system operates.
{CAUTION:
Stowing of articles under the passenger’s seat
or between the passenger’s seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the service
manual have information about servicing your vehicle
and the airbag system. To purchase a service manual,
seeService Publications Ordering Information on
page 8-16.
{CAUTION:
For up to 10 seconds after the ignition is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.

If you have additional transmitters to program, take
transmitter 1 out of the transmitter pocket and place
transmitter 2 in the pocket. This can be done repeatedly
until up to 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 Acc. button.
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 down. 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.

Power Window Initialize
After a power reconnect such as battery replacement,
the express-up and index-up features will not function
until the system is initialized. Once power is restored,
do the following:
1. Close the door.
2. Raise the window by holding the up arrow on
the power window switch.
3. Hold the up arrow for three seconds after
the window is closed. Release the switch.
Then hold the up arrow again for three seconds.
The express-up system must be initialized to operate
the windows with the door open.
Express-Down Window
This feature is on both power windows. Press the
down arrow on the switch to the second position to
activate the express-down feature. If you want to stop
the window as it is lowering, press the switch again.
Express-Up Window
This feature is on both power windows. Press the up
arrow on the switch to the second position to activate
the express-up feature. If you want to stop the window
as it is raising, press the switch again.
Express Window Anti-Pinch Feature
If any object is in the path of the window when
the express-up is active, the window will stop at the
obstruction and auto-reverse to a preset factory position.
Weather conditions such as severe icing may also
cause the window to auto-reverse. The window
will return to normal operation once the obstruction or
condition is removed.
{CAUTION:
If express override is activated, the window will
not reverse automatically. You or others could
be injured and the window could be damaged.
Before you use express override, make sure
that all people and obstructions are clear of the
window path.
Express Window Anti-Pinch Override
In an emergency, the anti-pinch feature can be
overridden in a supervised mode. Hold the window switch
all the way down in the express position. The window will
rise for as long as the switch is held. Once the switch is
released, the express mode is re-activated.
In this mode, the window can still close on an object in
its path. Use care when using the override mode.

Arming the System
To arm the system:
Press the lock button on the keyless access
transmitter.
Open the door. Lock the door with the power
door lock switch. The security light should
ash. Remove the keyless access transmitter
from the interior of the vehicle and close the door.
The security light will stop ashing and stay on.
After 30 seconds, the light should turn off.
The vehicle can be programmed to automatically
lock the doors and arm the system when you
exit the vehicle. SeeDIC Vehicle Personalization
on page 3-76.
Now, if a door or the trunk lid is opened without the
keyless access transmitter, the alarm will go off. Your
horn will sound for two minutes, then it will go off to save
battery power. And, your vehicle will not start without
a keyless transmitter present.
The theft-deterrent system will not arm if you lock the
driver’s door with the power door lock switch after
the doors are closed.
If your passenger stays in the vehicle when you leave
with the keyless access transmitter, have the passenger
lock the vehicle after the doors are closed. This way the
alarm will not arm, and your passenger will not set it off.
Testing the Alarm
To test the system:
1. Make sure the trunk lid is latched.
2. Lower the window on the driver’s door.
3. Manually arm the system.
4. Close the doors and wait 30 seconds.
5. Reach through the open window and manually
pull the release lever on the oor.
6. Turn off the alarm by pressing the unlock button
on the transmitter.
If the alarm is inoperative, check to see if the horn
works. If not, check the horn fuse. SeeFuses and
Circuit Breakers on page 6-90. If the horn works, but
the alarm doesn’t go off, see your dealer/retailer.
Disarming the System
Always use your keyless access transmitter to unlock
a door either by pressing the unlock button on the
transmitter or by squeezing the door handle sensor while
you have the transmitter with you. Unlocking a door any
other way will set off the alarm. If your alarm sounds,
press the unlock button on the keyless access transmitter
to disarm it.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

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 you 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 3-63for 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 3-63.3. 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.

Torque Lock
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may nd it difficult to pull the
shift lever out of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave the
driver’s seat. To nd out how, see “Shifting Into
PARK (P)” listed previously in this section.
When you are ready to drive, move the shift lever out
of PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission,
so you can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
This vehicle is equipped with an electronic shift lock
release system. The shift lock release is designed to:
Prevent shifting out of PARK (P) unless the
vehicle is running or in Accessory mode and
the regular brake pedal is applied.
The shift lock release is always functional except in the
case of an uncharged or low voltage (less than 9 volt)
battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 6-41
To shift out of PARK (P) use the following:
1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of PARK (P):
1. Fully release the shift lever button.
2. While holding down the brake pedal, press the
shift lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from PARK (P),
consult your dealer/retailer or a professional towing
service.
