2009 CADILLAC XLR change key battery

Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
If there is a decrease in the keyless access transmitter
range, try this:
Check the distance. The transmitter may be too far
from the vehicle. It may be necessary 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 the transmitter’s battery. See “Battery
Replacement” underKeyless Access System
Operation on page 2-5.
Make sure that an electronic device such as a
cellular phone or lap top computer is not causing
interference.
If the transmitter is still not working correctly, see
your dealer/retailer or a qualied technician for
service.
Keyless Access System Operation
The Keyless Access System transmitter functions
work up to 100 feet (30 m) away from the vehicle.
Keyless Unlocking
Press the door handle sensor to unlock and open the
doors if the keyless access transmitter is within range.
SeeDoor Locks on page 2-10and “Passive Unlocking”
underDIC Vehicle Personalization on page 3-72for
additional information.
Keyless Locking
The doors lock after several seconds if all doors are
closed and at least one keyless access transmitter
has been removed from the interior of the vehicle.
To customize whether the doors automatically lock when
exiting the vehicle, see″Passive Locking″underDIC
Vehicle Personalization on page 3-72for additional
information.

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.
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.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. Once cranking has been
initiated, the engine continues cranking for a few
seconds or until the vehicle starts. If the engine does
not start, cranking automatically stops after 15 seconds
to prevent cranking motor damage. To prevent gear
damage, this system also prevents cranking if the
engine is already running.Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the engine
operates. Before adding electrical equipment, check
with your dealer/retailer. If you do not, the engine
might not perform properly. Any resulting damage
would not be covered by the vehicle warranty.
Stopping the Engine
Move the shift lever to P (Park) and press the Acc. button
located on the instrument panel. If the shifter is not in
P (Park), the engine shuts off and the vehicle goes into
the Accessory Mode. The DIC displays SHIFT TO PARK.
Once the shifter is moved to P (Park), the vehicle
turns off.
The DIC displays NO FOB, OFF OR RUN?, if the
keyless access transmitter is not detected inside the
vehicle when it is turned off.
SeeDIC Warnings and Messages on page 3-60for
more information.

Charging System Light
This light comes on briey
when the ignition key is
turned to START, but
the engine is not running,
as a check to show it
is working.
If it does not, have the vehicle serviced by your
dealer/retailer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
SeeDIC Warnings and Messages on page 3-60for more
information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.
Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of the
battery. When the engine
is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, the instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when the vehicle is at 10 volts or below. Have it checked
right away. Driving with the voltmeter reading at
10 volts or below could drain the battery and disable
the vehicle.
