WARNING: (Continued)
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 and
seat-mounted side impact airbag (if equipped),
no system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though the airbag(s) are off.
Secure rear-facing child restraints in a rear seat,
even if the airbag(s) are 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 right front passenger airbag and seat‐mounted side
impact airbag if:
.The right front passenger seat is unoccupied.
.The system determines that an infant is present in
a rear-facing infant seat.
.The system determines that a small child is
present in a child restraint.
.The system determines that a small child is
present in a booster seat.
.A right front passenger takes his/her weight off of
the seat for a period of time.
.The right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints.
.Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
right front passenger frontal airbag and seat‐mounted
side impact airbag, the off indicator will light and stay lit
to remind you that the airbags are off. See Passenger
Airbag Status Indicator on page 4‑48.
The passenger sensing system is designed to turn on
(may inflate) the right front passenger frontal airbag and
seat‐mounted side impact airbag anytime the system
senses that a person of adult size is sitting properly in
the right front passenger seat.
When the passenger sensing system has allowed the
airbags to be enabled, the on indicator will light and
stay lit to remind you that the airbags are active.

Black plate (66,1)Cadillac DTS Owner Manual - 2011
For some children who have outgrown child restraints
and for very small adults, the passenger sensing
system may or may not turn off the right front passenger
frontal airbag and seat-mounted side impact airbag,
depending upon the person’s seating posture and body
build. Everyone in the vehicle who has outgrown child
restraints should wear a safety belt properly—whether
or not there is an airbag for that person.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. See Airbag Readiness Light
on page 4‑48
for more information, including important safety
information.
If the On Indicator is Lit for a Child
Restraint
If a child restraint has been installed and the on
indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle. 3. Remove any additional items from the seat such
as blankets, cushions, seat covers, seat heaters,
or seat massagers.
4. Reinstall the child restraint following the directions provided by the child restraint manufacturer and
refer to Securing a Child Restraint in the Right
Front Seat Position on page 2‑50.
5. If, after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, turn the
vehicle off. Then slightly recline the vehicle
seatback and adjust the seat cushion, if adjustable,
to make sure that the vehicle seatback is not
pushing the child restraint into the seat cushion.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint. See Head Restraints
on
page 2‑2.
6. Restart the vehicle. If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle,
and check with your dealer.

Content Theft-Deterrent
The security light
is located on the
instrument panel cluster. To arm the system:
1. Open the door.
2. Lock the door using the power door lock switch with the door open or the Remote Keyless Entry
(RKE) transmitter. The security light will flash.
3. Close all the doors. The security light will come on and stay on for approximately 30 seconds.
If a door or the trunk is opened without a key or a RKE
transmitter the horn will sound and the lamps will flash
for about 30 seconds.
The theft-deterrent system will not arm if you lock the
doors with a key or use the manual door lock. It arms
only if you use a power door lock with the door open or
the RKE transmitter.
