ECU CADILLAC XLR 2005 1.G Owner's Manual

Programming the HomeLink®
Transmitter
Do not use the HomeLink®Transmitter 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. If you have a newer
garage door opener with rolling codes, please be
sure to follow Steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on
the internet at: www.homelink.com or by calling
1-800-355-3515.Be sure that people and objects are clear of the
garage door or gate operator you are programming.
When programming a garage door, it is advised to
park outside of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Programming HomeLink®
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
®
buttons while keeping the indicator light in view.

Rear Storage Area
There is a cargo divider located in the trunk to keep
cargo from getting in the way of the retractable hardtop.
The cargo divider must be in place for the top to move.To install the cargo divider, snap the bottom of the
divider onto the snaps (B) located on the oor of the
trunk. Then, swing the divider up and place the pins on
each side of the divider into the notches (A) on either
side of the trunk.
There is also a storage compartment located in the
trunk on the passenger’s side.
To access the storage compartment, unsnap the lid.
To reinstall the lid, line up the opening in the lid over the
snap and push down into place.
Convenience Net
Your vehicle is equipped with a convenience net.
The convenience net attaches to the oor of the trunk.
Put small loads, like grocery bags, behind the net.
The net is not for larger, heavier loads. Store them in
the trunk as far forward as you can. When not using the
net, hook the net to the tabs securing it to the sill plate.

{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbags, it means
that something may be wrong with the airbag
system. The passenger’s airbags could inate
even though the switch is off. If this ever
happens, do not let anyone whom the national
government has identied as a member of a
passenger airbag risk group sit in the
passenger’s position (for example, do not
secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced.
SeeAirbag Off Switch on page 1-44.
Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of your
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, your instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when your vehicle is at 10 volts or below. Have
it checked right away. Driving with the voltmeter reading
at 10 volts or below could drain your battery and
disable your vehicle.
