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.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module (located under the driver’s seat), or
the inside rearview mirror can affect the operation
of the airbag system. If you have questions,
call Customer Assistance. The phone numbers
and addresses for Customer Assistance are in
Step Two of the Customer Satisfaction Procedure
in this manual. SeeCustomer Satisfaction
Procedure on page 7-2.

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.
1-65

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. See
Airbag Readiness Light on page 3-38.

One key works all of the
lock cylinders on the
vehicle.
Your vehicle has an Immobilizer Vehicle Theft-Deterrent
System. The key has a transponder in the key head
that matches a decoder in the vehicle’s steering column.
If a replacement key or any additional key is needed,
you must purchase it from your dealer. The key will have
PK3+ stamped on it. Keep the bar code tag that
came with the original keys. Give this tag to your dealer
if you need a new key made.
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.
In an emergency, contact Cadillac Roadside Service
®.
SeeRoadside Service on page 7-5.If your vehicle is equipped with the OnStar
®system with
an active subscription and you lock your keys inside
the vehicle, OnStar
®may be able to send a command to
unlock your vehicle. SeeOnStar®System (CTS) on
page 2-44for more information.

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 2-5.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
With this feature, you can lock and unlock the doors or
the trunk and turn on your vehicle’s interior lamps
from about 10 feet (3 m) away using the remote
keyless entry transmitter supplied with your vehicle.
Q(Lock):Press this
symbol on the remote
keyless entry transmitter to
lock the doors. This also
arms the theft-deterrent
system.
You can program your vehicle so that the exterior lamps
will ash and/or the horn will sound when you lock
the doors with the remote keyless entry transmitter.
SeeDIC Vehicle Personalization on page 3-74for more
information on programming this feature.
If your vehicle is programmed for remote conrmation,
the doors must be closed for this feature to work. If a door
is open, remote conrmation will be canceled.
W(Unlock):Press this symbol on the remote keyless
entry transmitter to unlock the driver’s door. This also
disarms the theft-deterrent system. Press the button
again to unlock the rest of the doors.
2-5

You can program your vehicle so that the exterior lamps
will ash when you unlock the doors with the remote
keyless entry transmitter. SeeDIC Vehicle
Personalization on page 3-74for more information on
programming this feature.
If your vehicle is programmed for remote conrmation,
the doors must be closed for this feature to work. If a door
is open, remote conrmation will be canceled.
L(Panic Alarm):The remote keyless entry transmitter
comes equipped with an instant panic alarm. Press
the horn symbol when the ignition is turned off. The horn
will sound and the exterior lamps will ash for up to
30 seconds. To stop the instant panic alarm, press the
symbol again or turn the ignition to ON.
V(Trunk):Press this button to open the trunk.
The remote keyless entry transmitter can be used to
recall the memory settings for up to two drivers.
For more information, seeDIC Vehicle Personalization
on page 3-74andMemory Seat and Mirrors on
page 2-52.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is 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 remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of
four transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
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.
