CADILLAC STS 2005 1.G Repair Manual

In many crashes severe enough to inate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for
your airbag system. If you do not get them,
the airbag system will not be there to help protect
you in another crash. A new system will include
airbag modules and possibly other parts. The
service manual for your vehicle covers the need to
replace other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module which records information after
a crash. SeeVehicle Data Collection and Event
Data Recorders on page 7-8.
Let only qualied technicians work on your airbag
system. Improper service can mean that an
airbag system will not work properly. See your
dealer for service.Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, or the airbag
covering on the driver’s and right front passenger’s
seatback, or the side impact airbag covering on
the ceiling near the side windows, the bag may not
work properly. You may have to replace the
airbag module in the steering wheel, both the airbag
module and the instrument panel for the right
front passenger’s airbag, the airbag module and
seatback for the driver’s and right front passenger’s
seat-mounted side impact airbags, or side impact
airbag module and ceiling covering for the
roof-mounted side impact airbag. Do not open or
break the airbag coverings.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
airbag system. To purchase a service manual, see
Service Publications Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are too close to an
airbag when it inates. Avoid wires wrapped
with yellow tape, yellow coverings or yellow
connectors. They are probably part of the
airbag systems. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
The airbag system does not need regular maintenance.
Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)

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 have 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 was not being used at the time of
the collision.
If an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
If the frontal airbags inate, you will also need to
replace the driver’s and right front passenger’s safety
belt buckle assembly. Be sure to do so. Then the
new buckle assembly will be there to help protect you
in a collision.
After a crash you may need to replace the driver and
front passenger’s safety belt buckle assemblies, even
if the frontal airbags have not deployed. The driver and
front passenger’s safety belt buckle assemblies
contain the safety belt pretensioners. Have your safety
belt pretensioners checked if your vehicle has been
in a collision, or if your airbag readiness light stays on
after you start your vehicle or while you are driving.
SeeAirbag Readiness Light on page 3-63.

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
Keyless Access System Operation on page 2-4.
Check to make sure that an electronic device such
as a cellular phone or lap top computer is not
causing interference.
If you are still having trouble, see your dealer or a
qualied technician for service.
Keyless Access System Operation

as much as 30 feet (10 m) away.
The Keyless Access System also lets you lock and
unlock the vehicle’s doors and access the trunk without
removing the remote transmitter from your pocket,
purse, briefcase, etc. The system operates when the
transmitter is located within 3 feet (1 m) of the door or

Matching Transmitter(s) to Your
Vehicle
Each Keyless Access System is coded to allow only
transmitters programmed to your vehicle to work.
If a transmitter is lost or stolen, a replacement can be
purchased and programmed through your GM
dealer. Your GM dealer can reprogram your vehicle so
lost or stolen transmitters no longer work with your
vehicle. Each vehicle can have a maximum of
four transmitters matched to it.
To match a new transmitter to your vehicle when you
have a recognized transmitter, do the following.
Two recognized transmitters are required for Canadian
owners.
1. The vehicle must be off.
2. Have the recognized transmitter and the new,
unrecognized transmitter(s) with you.
3. Insert the vehicle key into the key lock cylinder
located on the outside of the driver’s door.
4. Turn the key to the unlock position ve times within
ve seconds.
5. The Driver Information Center (DIC) will display
READY FOR FOB #X, where X can be 2, 3 or 4.6. Place the new, unrecognized transmitter into the
transmitter pocket with the transmitter buttons
facing the front of the vehicle. The transmitter
pocket is inside the console bin located between
the driver and front passenger seats.
7. Once the transmitter is programmed, a beep will
sound. The DIC will display READY FOR #X,
where X can be 3 or 4, or MAX # FOBS LEARNED.
8. Remove the transmitter from the transmitter pocket
and press the unlock button on the keyless access
transmitter two times.
