BUICK REGAL 2004 Repair Manual

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system may
not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.If you’ve had a crash, do you need new belts or LATCH
system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system wasn’t being used at the time of
the collision.
If an air bag inates, you’ll need to replace air bag
system parts. See the part on the air bag system earlier
in this section.

{CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. They
could operate the power windows or other
controls or even make the vehicle move. The
children or others could be badly injured or
even killed. Do not leave the keys in a vehicle
with children.
2-2

The vehicle has two keys that are used for separate
functions.
The ignition key is for the
ignition only.
The door key is for the
driver door and all
other locks.The keys have unique codes embedded in them to help
prevent theft. SeePASS-Key®II on page 2-16for
more information.
Your dealer or Buick Roadside Assistance can provide
the correct codes for the keys. Contact your dealer
or seeRoadside Assistance Program on page 7-6for
more information.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If the vehicle has the OnStar
®system with an active
subscription, and the keys were locked inside, a
command could be sent by the OnStar
®system to
unlock the vehicle. SeeOnStar®System on page 2-34
for more information.
Remote Keyless Entry System
Your keyless entry system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
2-3

This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need 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 to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer or a
qualied technician for service.

vehicle. The ignition must be off for this feature to
work. The interior lamps will stay on until either the
ignition is turned to RUN or until 40 seconds has
elapsed. If a door is opened during this time, the timed
lighting will be canceled, and the interior lamps will
remain on. Also see “Entry Lighting” underInterior
Lamps on page 3-14for more information.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is uniquely coded
to prevent another transmitter from unlocking your
vehicle. If a transmitter is lost or stolen, a replacement
can be purchased through your dealer. Remember
to bring any additional transmitters so they also can be
re-coded to match the new transmitter. Once your
dealer has coded the new transmitter, the lost
transmitter cannot unlock the vehicle. The vehicle can
have a maximum of four transmitters coded to it.
2-7

Battery Replacement
The battery in your remote keyless entry transmitter
should last about three years.
If the battery is weak the transmitter will not work within
its normal range. It is probably time to change the
battery if you have to be very close to the vehicle before
the transmitter works.
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.To replace the battery do the following:
1. Insert a at object like a thin coin into the slot on
the back of the transmitter and pry apart the front
and back.
2. Remove the old battery, but do not use a metal
object to do this. Make sure the new battery is a
type CR2032 or equivalent, and that the positive (+)
side of the battery is facing down.
3. Snap the front and back of the transmitter together.
4. Resynchronize and test the operation of the
transmitter with the vehicle.
Resynchronization
After the battery has been changed in the remote
keyless transmitter, it will need to be resynchronized. To
do this, press and hold both the LOCK and UNLOCK
buttons until you hear one horn chirp.
