2008 Cadillac DTS Owner ManualM

If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
Remove any additional material from the seat such as
blankets, cushions, seat covers, seat heaters or seat
massagers before reinstalling or securing the child
restraint.
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/retailer.
To remove the child restraint, unbuckle the vehicle’s
safety belt and let it go back all the way.Airbag System
Your vehicle has the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.
A seat-mounted side impact airbag for the driver.
A seat-mounted side impact airbag for the right front
passenger.
Your vehicle may also have the following airbags:
A roof-rail airbag for the driver and the passenger
seated directly behind the driver.
A roof-rail airbag for the right front passenger and
the passenger seated directly behind the right
front passenger.
All of the airbags in your vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
1-53

For frontal airbags, the word AIRBAG will appear on the
middle part of the steering wheel for the driver and
on the instrument panel for the right front passenger.
With seat-mounted side impact airbags, the word
AIRBAG will appear on the side of the seatback closest
to the door.
With roof-rail airbags, the word AIRBAG will appear
along the headliner or trim.
Airbags are designed to supplement the protection
provided by safety belts. Even though today’s airbags
are also designed to help reduce the risk of injury
from the force of an inating bag, all airbags must inate
very quickly to do their job.Here are the most important things to know about the
airbag system:
{CAUTION:
You can be severely injured or killed in a crash
if you are not wearing your safety belt — even
if you have airbags. Wearing your safety belt
during a crash helps reduce your chance of
hitting things inside the vehicle or being
ejected from it. Airbags are “supplemental
restraints” to the safety belts. All airbags are
designed to work with safety belts, but do not
replace them.
1-54

{CAUTION:
Frontal airbags are designed to deploy in
moderate to severe frontal and near frontal
crashes. They are not designed to inate in
rollover, rear crashes, or in many side crashes.
Seat-mounted side impact airbags and roof-rail
airbags are designed to inate in moderate to
severe crashes where something hits the side
of your vehicle. They are not designed to
inate in frontal, in rollover, or in rear crashes.
Everyone in your vehicle should wear a safety
belt properly — whether or not there is an
airbag for that person.
{CAUTION:
Airbags inate with great force, faster than the
blink of an eye. Anyone who is up against, or
very close to, any airbag when it inates can
be seriously injured or killed. Do not sit
unnecessarily close to the airbag, as you
would be if you were sitting on the edge of
your seat or leaning forward. Safety belts help
keep you in position before and during a
crash. Always wear your 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.
1-55

If your vehicle has roof-rail airbags for the driver, right
front passenger, and second row outboard passengers,
they are in the ceiling above the side windows.
{CAUTION:
If something is between an occupant and an
airbag, the airbag might not inate properly or
it might force the object into that person
causing severe injury or even death. The path
of an inating 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
ination 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 inating roof-rail airbag
will be blocked. Driver Side shown, Passenger Side similar
1-58

Your vehicle also has a dual-depth passenger airbag
that adjusts the restraint according to crash severity,
seat location, and safety belt status using electronic
frontal sensor(s) and other special sensors which enable
the sensing system to monitor the position of the front
passenger seat. The passenger airbag inates to a
reduced depth when the passenger seat is in a forward
position. For more rearward front seating positions,
the passenger airbag may inate to an increased depth
(a full deployment), based on safety belt status and
the crash severity measured early in the event. (Always
wear your safety belt, even with frontal airbags.)
Your vehicle has seat-mounted side impact airbags.
Your vehicle may have roof-rail airbags. SeeAirbag
System on page 1-53. Seat-mounted side impact and
roof-rail airbags are intended to inate in moderate
to severe side crashes. Seat-mounted side impact and
roof-rail airbags will inate if the crash severity is
above the system’s designed threshold level. The
threshold level can vary with specic vehicle design.Seat-mounted side impact and roof-rail airbags are not
intended to inate in frontal impacts, near-frontal
impacts, rollovers, or rear impacts. A seat-mounted side
impact airbag is intended to deploy on the side of the
vehicle that is struck. Both roof-rail airbags will
deploy when either side of the vehicle is struck.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, ination is determined by
what the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For seat-mounted
side impact and roof-rail airbags, deployment is
determined by the location and severity of the side
impact.
1-60

What Makes an Airbag Inate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from
the inator. Gas from the inator lls the airbag causing
the bag to break out of the cover and deploy. The
inator, the airbag, and related hardware are all part of
the airbag module.
Frontal airbag modules are located inside the steering
wheel and instrument panel. For vehicles with
seat-mounted side impact airbags, there are airbag
modules in the side of the front seatbacks closest to the
door. For vehicles with roof-rail airbags, there are
airbag modules in the ceiling of the vehicle, near the
side windows that have occupant seating positions.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the impact
more evenly over the occupant’s upper body, stopping
the occupant more gradually. Seat-mounted side impact
and roof-rail airbags distribute the force of the impact
more evenly over the occupant’s upper body.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-59for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
1-61

What Will You See After an Airbag
Inates?
After the frontal airbags and seat-mounted side impact
airbags inate, they quickly deate, so quickly that
some people may not even realize an airbag inated.
Roof-rail airbags may still be at least partially inated for
some time after they deploy. Some components of
the airbag module may be hot for several minutes. For
location of the airbag modules, seeWhat Makes an
Airbag Inflate? on page 1-61.
The parts of the airbag that come into contact with you
may be warm, but not too hot to touch. There may
be some smoke and dust coming from the vents in the
deated airbags. Airbag ination does not prevent
the driver from seeing out of the windshield or being
able to steer the vehicle, nor does it prevent people from
leaving the vehicle.
{CAUTION:
When an airbag inates, there may be dust in
the air. This dust could cause breathing
problems for people with a history of asthma
or other breathing trouble. To avoid this,
everyone in the vehicle should get out as soon
as it is safe to do so. If you have breathing
problems but cannot get out of the vehicle
after an airbag inates, then get fresh air by
opening a window or a door. If you experience
breathing problems following an airbag
deployment, you should seek medical
attention.
The vehicle has a feature that may automatically unlock
the doors, turn the interior lamps on, and turn the
hazard warning ashers on when the airbags inate.
You can lock the doors, turn the interior lamps off, and
turn the hazard warning ashers off by using the
controls for those features.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, overhead console, front
sensors, side impact sensors, or airbag wiring can
affect the operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger’s position, which
includes sensors that are part of the passenger’s
seat. The passenger sensing system may not
operate properly if the original seat trim is replaced
with non-GM covers, upholstery or trim, or with GM
covers, upholstery or trim designed for a different
vehicle. Any object, such as an aftermarket seat
heater or a comfort enhancing pad or device,
installed under or on top of the seat fabric, could alsointerfere with the operation of the passenger sensing
system. This could either prevent proper deployment
of the passenger airbag(s) or prevent the passenger
sensing system from properly turning off the
passenger airbag(s). SeePassenger Sensing
System on page 1-63.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. 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.
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: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. See
Customer Satisfaction Procedure on page 7-2.
In addition, your dealer/retailer and the service manual
have information about the location of the airbag
sensors, sensing and diagnostic module and airbag
wiring.
