2004 BUICK RANDEZVOUS ECU

If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse. SeeFuses
and Circuit Breakers on page 5-109. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the rst key may be
faulty. See your dealer who can service the
PASS-Key
®III to have a new key made.
It is possible for the PASS-Key
®III decoder to program
the transponder value of a new or replacement key.
Up to 10 additional keys may be programmed for
the vehicle. This procedure is for programming additional
keys only. If all the currently programmed keys are
lost or do not operate, you must see your dealer or a
locksmith who can service PASS-Key
®III to have
keys made and programmed to the system.
See your dealer who can service PASS-Key
®III to get a
new key blank that is a cut exactly as the ignition key
that operates the system.
Canadian Owners:If you lose or damage your keys,
only a GM dealer can service PASS-Key
®III to
have new keys made. To program additional keys you
will need two current driver’s keys (black in color).
You must add a step to the following procedure. After
Step 3 repeat Steps 1 through 3 with the second current
driver’s key. Then continue with Step 4.To program the new PK3
®key do the following:
1. Verify the new key has PK3
®stamped on it.
2. Insert the original key in the ignition and start the
engine. If the engine will not start, see your dealer
for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to ON
within 10 seconds of removing the previous key.
5. The SECURITY message will turn off once the key
has been programmed. It may not be apparent that
the SECURITY message went on due to how
quickly the key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the SECURITY message
comes on and stays on, you will be able to restart your
engine if you turn it off. Your PASS-Key
®III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
®III system at this time.
If you lose or damage a PASS-Key
®III key, see your
dealer who can service PASS-Key®III to have a
new key made.

Outside Convex Mirror
Your passenger’s side mirror is convex. A convex
mirror’s surface is curved so you can see more from
the driver’s seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Heated Mirrors
If your vehicle has this feature, the outside rearview
mirrors are heated when you activate the rear window
defogger. See “Rear Window Defogger” under
Climate Control System on page 3-28.

HomeLink, a combined universal transmitter and
receiver, provides a way to replace up to three
hand−held transmitters used to activate devices such as
gate operators, garage door openers, entry door
locks, security systems and home lighting. Additional
HomeLink information can be found on the internet
at www.homelink.com or by calling 1−800−355−3515.
If your vehicle is equipped with the HomeLink
®
transmitter, it complies with Part 15 of the FCC Rules.

(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired
operation.This device complies with RSS-210 of Industry Canada.

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.
2-35

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.
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.3. Simultaneously press and hold both the desired
button on HomeLink
®and the hand-held transmitter
button. Do not release the buttons until Step 4
has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
4. The indicator light will ash slowly at rst and then
rapidly after HomeLink
®successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained HomeLink
®button
and observe the indicator light.
If the indicator light stays on constantly,
programming is complete and your device should
activate when the HomeLink
®button is pressed and
released.
To program the remaining two HomeLink
®buttons,
begin with Step 2 under “Programming HomeLink®.”
Do not repeat Step 1 as this will erase all of the
programmed channels.
If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps 6 through 8 following to complete the
programming of a rolling-code equipped device
(most commonly, a garage door opener).

Notice:Loading cargo on the luggage carrier that
weighs more than 220 lbs (100 kg) or hangs over the
rear or sides of the vehicle may damage your vehicle.
Load cargo so that it rests on the slats as far forward
as possible and against the side rails, making sure to
fasten it securely.
When you carry cargo on the luggage carrier of a
proper size and weight, put it on the slats and distribute
the weight evenly. Then slide the crossrail up against
the rear of the load to keep it from moving. You can then
tie it down. Cargo containers must be loaded on the
crossrails only.Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, seeLoading Your Vehicle on
page 0-0.
To prevent damage or loss of cargo as you’re driving,
check now and then to make sure the luggage
carrier and cargo are still securely fastened.
Loading things onto the luggage carrier can interfere with
the performance of your XM™ Satellite Radio System.
Your luggage carrier has release levers within the end
of each crossrail support.
