2-26 Keys, Doors, and Windows
If the engine still does not start and
the key appears to be undamaged
or the light continues to stay on, try
another key.
If the engine still does not start with
the other key, the vehicle needs
service. If the vehicle does start,
the first key may be damaged. See
your dealer who can service the
theft-deterrent system and have a
new key made.
It is possible for the theft-deterrent
system decoder to learn the
transponder value of a new or
replacement key. Up to 10 keys
can be programmed for the vehicle.
The following procedure is for
programming additional keys only.
To program a new key:
1. Verify that the new key has
1
stamped on it.
2. Insert the current 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 LOCK/OFF, and
remove the key.
4. Insert the key to be programmed and turn it to ON/RUN within
five seconds of the ignition being
turned to LOCK/OFF in Step 3.
5. The security light will turn off once the key has been
programmed. It may not be
apparent that the security light
went on due to how quickly the
key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to be
programmed.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
Immobilizer Operation
(Keyless Access)
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the ignition
control knob is turned to LOCK/OFF.
The immobilization system is
disarmed when the ignition control
knob is pushed in and a valid
transmitter is found in the vehicle.
The security light, located in the
instrument panel cluster, comes on
if there is a problem with arming or
disarming the theft-deterrent
system.

Keys, Doors, and Windows 2-27
One or more keyless access
transmitters can be matched to the
vehicle's immobilizer control unit.
Only a correctly matched keyless
access transmitter will start the
vehicle. If the keyless access
transmitter is ever damaged, you
may not be able to start your
vehicle.
When trying to start the vehicle, the
security light comes on briefly when
the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition control knob off and try
again.If the ignition control knob does not
rotate, and the keyless access
transmitter appears to be
undamaged, try another keyless
access transmitter. Or, you may try
placing the transmitter in the
transmitter pocket located in the
center console. See
“Electronic Key
Not Detected” underKey and Lock
Messages on page 5‑37.
If the ignition control knob still does
not rotate with the other transmitter,
the vehicle needs service. If the
ignition control knob does rotate, the
first transmitter may be faulty. See
your dealer who can service the
theft-deterrent system and have a
new keyless access transmitter
programmed to the vehicle. It is possible for the immobilizer
system to learn new or replacement
keyless access transmitters. Up to
four keyless access transmitters can
be programmed for the vehicle. To
program additional transmitters, see
“Programming Transmitters to the
Vehicle”
for keyless access under
Remote Keyless Entry (RKE)
System Operation (Key Access) on
page 2‑5 orRemote Keyless Entry
(RKE) System Operation (Keyless
Access) on page 2‑6.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.

3-14 Seats and Restraints
.Wear the shoulder belt over the
shoulder and across the chest.
These parts of the body are best
able to take belt restraining
forces. The shoulder belt locks if
there is a sudden stop or crash.
{WARNING
You can be seriously injured,
or even killed, by not wearing
your safety belt properly.
.Never allow the lap or
shoulder belt to become
loose or twisted.
.Never wear the shoulder belt
under both arms or behind
your back.
.Never route the lap or
shoulder belt over an
armrest.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat isadjustable, so you can sit up
straight. To see how, see “Seats”
in the Index.
2. Pick up the latch plate and pull the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
3. Push the latch plate into the
buckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3‑18.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster, move it to the
height that is right for you. See

Black plate (18,1)Cadillac CTS/CTS-V Owner Manual (Include Mex) - 2012
3-18 Seats and Restraints
To remove and store the comfort
guide, squeeze the belt edges
together so that the safety belt can
be removed from the guide. Pull the
guide upward to expose its storage
clip, and then slide the guide onto
the clip. Turn the guide and clip
inward and slide them in between
the seatback and the interior body,
leaving only the loop of the elastic
cord exposed.
Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.
The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child seats. To
wear it, attach it to the regular safety
belt. For more information, see the
instruction sheet that comes with
the extender.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors, and
anchorages are all working properly.

Seats and Restraints 3-21
{WARNING
Because airbags inflate with great
force and faster than the blink of
an eye, anyone who is up
against, or very close to any
airbag when it inflates can be
seriously injured or killed. Do not
sit unnecessarily close to any
airbag, as you would be if sitting
on the edge of the seat or leaning
forward. Safety belts help keep
you in position before and during
a crash. Always wear a safety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
{WARNING
Children who are up against,
or very close to, any airbag
when it inflates can be seriously
injured or killed. Airbags plus
lap-shoulder belts offer protection
for adults and older children, but
not for young children and infants.
Neither the vehicle's safety belt
system nor its airbag system is
designed for them. Young
children and infants need the
protection that a child restraint
system can provide. Always
secure children properly in the
vehicle. To read how, seeOlder
Children on page 3‑34 orInfants
and Young Children on
page 3‑37.
There is an airbag readiness light
on the instrument panel cluster,
which shows the airbag symbol. The
system checks the airbag electrical
system for malfunctions. The light
tells you if there is an electrical
problem. See Airbag Readiness
Light on page 5‑17 for more
information.

Seats and Restraints 3-23
Driver Side Shown, PassengerSide Similar
The roof-rail airbags for the driver,
front outboard passenger, and
second row outboard passengers
are in the ceiling above the side
windows.
{WARNING
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
that person causing severe injury
or even death. The path of an
inflating airbag must be kept
clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.
Do not use seat accessories that
block the inflation path of a
seat-mounted side impact airbag.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie‐down
through any door or window
opening. If you do, the path of an
inflating roof-rail airbag will be
blocked.
When Should an Airbag
Inflate?
Frontal airbags are designed to
inflate in moderate to severe frontal
or near frontal crashes to help
reduce the potential for severe
injuries mainly to the driver's or
outboard front passenger's head
and chest. However, they are only
designed to inflate if the impact
exceeds a predetermined
deployment threshold. Deployment
thresholds are used to predict how
severe a crash is likely to be in time
for the airbags to inflate and help
restrain the occupants.
Whether the frontal airbags will or
should deploy is not based primarily
on how fast the vehicle is traveling.
It depends largely on what is hit, the
direction of the impact, and how
quickly the vehicle slows down.

Black plate (28,1)Cadillac CTS/CTS-V Owner Manual (Include Mex) - 2012
3-28 Seats and Restraints
The passenger sensing system
works with sensors that are part of
the front outboard passenger seat.
The sensors are designed to detect
the presence of a properly-seated
occupant and determine if the front
outboard passenger frontal airbag
should be enabled (may inflate)
or not.
According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.
We recommend that children be
secured in a rear seat, including: an
infant or a child riding in a
rear-facing child restraint; a child
riding in a forward-facing child seat;
an older child riding in a booster
seat; and children, who are large
enough, using safety belts.
A label on the sun visor says,
“Never put a rear-facing child seat in
the front.”This is because the risk to
the rear-facing child is so great,
if the airbag deploys.{WARNING
A child in a rear-facing child
restraint can be seriously injured
or killed if the right front
passenger airbag inflates. This is
because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the right front
passenger airbag inflates and the
passenger seat is in a forward
position.
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag is turned off.
(Continued)
WARNING (Continued)
Secure rear-facing child
restraints in a rear seat, even if
the airbag is off. If you secure a
forward-facing child restraint in
the right front seat, always move
the front passenger seat as far
back as it will go. It is better to
secure the child restraint in a
rear seat.
The passenger sensing system is
designed to turn off the front
outboard passenger airbag if:
.The front outboard passenger
seat is unoccupied.
.The system determines an infant
is present in a child restraint.
.A front outboard passenger
takes his/her weight off of the
seat for a period of time.
.There is a critical problem with
the airbag system or the
passenger sensing system.
