ECU CADILLAC XLR 2009 1.G Owner's Manual

Immobilizer Operation
The vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition is
turned off.
The immobilization system is disarmed when the ignition
is turned to OFF/ACCESSORY or START and a valid
transmitter is found in the vehicle.
You do not have to manually arm or disarm the system.
The security light comes on if there is a problem with
arming or disarming the theft-deterrent system.
The system has one or more keyless access transmitters
that are matched to an immobilizer control unit in the
vehicle. Only a correctly matched keyless access
transmitter starts the vehicle. The vehicle may not
start if the keyless access transmitter is damaged.
If the engine does not start and the security light comes
on, there may be a problem with the immobilizer system.
Press the START button again.If the vehicle does not start and the keyless access
transmitter appears to be undamaged, try another
keyless access transmitter. Or, place the transmitter in
the transmitter pocket. See “NO FOBS DETECTED”
underDIC Warnings and Messages on page 3-60for
additional information. Check the fuse. SeeFuses and
Circuit Breakers on page 6-83. If the engine still does not
start with the other transmitter, the vehicle needs service.
If the engine does start, the rst transmitter may be faulty.
See your dealer/retailer or have a new keyless access
transmitter programmed to the vehicle.
The immobilizer system can learn new or replacement
keyless access transmitters. Up to four keyless access
transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 2-5.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

OnStar®System
OnStar uses several innovative technologies and live
advisors to provide a wide range of safety, security,
information, and convenience services. If the airbags
deploy, the system is designed to make an automatic

emergency services be sent to your location. If the keys
are locked in the vehicle, call OnStar at 1-888-4-ONSTAR
to have a signal sent to unlock the doors. OnStar
Hands-Free Calling, including 30 trial minutes good

Turn-by-Turn Navigation service, with one trial route, is
available on most vehicles. Press the OnStar button to
have an OnStar advisor contact Roadside Service.OnStar service is provided subject to the OnStar Terms
and Conditions included in the OnStar Subscriber
glove box literature.
Some services such as Remote Door Unlock or Stolen
Vehicle Location Assistance may not be available until

Location information about the vehicle is only available
if the GPS satellite signals are unobstructed and
available.
The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.
Your Responsibility
Increase the volume of the radio if the OnStar advisor
cannot be heard. If the light next to the OnStar buttons
is red, the system may not be functioning properly.
Press the OnStar button and request a vehicle
diagnostic. If the light appears clear (no light is
appearing), your OnStar subscription has expired and
all services have been deactivated. Press the OnStar
button to conrm that the OnStar equipment is active.

Universal Home Remote System
Operation
On vehicles with this feature there are three round Light
Emitting Diode (LED) indicator lights above the Universal
Home Remote buttons, follow the instructions below.
This system provides a way to replace up to three remote
control transmitters used to activate devices such as
garage door openers, security systems, and home
automation devices.
Do not use this system with any garage door opener
that does not have the stop and reverse feature.
This includes any garage door opener model
manufactured before April 1, 1982.
Read the instructions completely before attempting to
program the transmitter. Because of the steps involved,
it may be helpful to have another person assist with
programming the transmitter.Be sure to keep the original remote control transmitter
for use in other vehicles, as well as, for future
programming. Only the original remote control
transmitter is needed for Fixed Code programming.
The programmed buttons should be erased when the
vehicle is sold or the lease ends. See “Erasing Universal
Home Remote Buttons” later in this section.
Park the vehicle outside of the garage when
programming a garage door. Be sure that people and
objects are clear of the garage door or gate that is being
programmed.Programming Universal Home
Remote — Rolling Code
For questions or help programming the Universal
Home Remote System, call 1-866-572-2728 or go to
learcar2u.com.
Most garage door openers sold after 1996 are Rolling
Code units.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before starting. Otherwise, the device will time out and
the procedure will have to be repeated.
