2005 Cadillac STS Owner ManualM

6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the
lap portion of the belt and feed the shoulder
belt back into the retractor. You may nd it helpful
to use your knee to push down on the child
restraint as you tighten the belt.
7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.
Airbag System
Your vehicle has six airbags:
A frontal airbag for the driver and another frontal
airbag for the right front passenger,
a seat-mounted side impact airbag for the driver
and another for the right front passenger,
a roof-mounted side impact airbag for the driver
and passenger directly behind the driver, and
a roof-mounted side impact airbag for the right front
passenger and the person seated directly behind
that passenger.
Frontal airbags are designed to help reduce the risk of
injury from the force of an inating airbag. But these
airbags must inate very quickly to do their job
and comply with federal regulations.
1-45

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.
Frontal airbags for the driver and right front
passenger are designed to deploy only in
moderate to severe frontal and near frontal
crashes. They are not designed to inate in
rollover, rear or low-speed frontal crashes, or in
many side crashes. And, for some unrestrained
occupants, frontal airbags may provide less
protection in frontal crashes than more
forceful airbags have provided in the past.
The seat-mounted side impact airbags and
roof-mounted side impact airbags are designed
CAUTION: (Continued)
CAUTION: (Continued)
to inate only 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:
Both frontal and side impact airbags inate
with great force, faster than the blink of an
eye. If you are too close to an inating airbag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for airbag ination before
and during a crash. Always wear your safety
belt even with frontal 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.
1-46

{CAUTION:
If something is between an occupant and an
airbag, the bag 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. And, because your vehicle
has side impact airbags, never secure anything
to the roof of your vehicle by routing the rope
or tiedown through any door or window
opening. If you do, the path of an inating
side impact airbag will be blocked. The path
of an inating airbag must be kept clear.
{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 let seat covers block
the ination path of a side impact airbag.
1-51

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.

Sunroof
The vehicle may have a power sunroof.
The switches that operate
the sunroof are located on
the overhead console.
To open or close the sunroof, the ignition must be ON
or Retained Accessory Power (RAP) must be active.
SeeRetained Accessory Power (RAP) on page 2-23.Express Open:The express open feature will operate
from the closed or partially open position. To express
open the power sunroof, press the driver’s side sunroof
switch rearward once. To stop the sunroof glass in a
desired position other than to the express open position,
press the switch again, in either direction, to stop the
movement. If the sunshade is in the closed position, it
will open with the sunroof, or it can be opened manually.
Vent Open:To open the power sunroof to the vent
position from the closed position, press and hold
the passenger’s side sunroof switch forward. The rear of
the sunroof panel will tilt upward to the full vent
position. The sunshade must be opened manually.
Close:To close the power sunroof, operate the controls
according to one of the following:
From the open position, press and hold the driver’s
side sunroof switch forward. The sunshade must be
closed manually.
From the vent position, press and hold the
passenger’s side sunroof switch rearward.
2-46

Anti-Pinch:If an object is in the path of the sunroof
while it is closing, the anti-pinch feature will detect the
object and stop the sunroof from closing at the point
of the obstruction. The sunroof will then return to
the full-open or vent position. To close the sunroof once
it has re-opened, refer to the two options previously
described under the “Close” feature instructions.
Vehicle Personalization
Your vehicle is equipped with personalization that allows
you to program certain features to a preferred setting
for up to two people. The number of programmable
features varies depending upon which vehicle options
are purchased.
On all vehicles, features such as climate control
settings, radio and XM™ preset settings, exterior lighting
at unlock and remote lock unlock conrmation and
language have already been programmed for your
convenience. Your vehicle also has an automatic door
locking feature that is always on. You cannot turn
the automatic door locking feature off. See
Programmable Automatic Door Locks on page 2-12.Some vehicles are equipped with additional features
that can be programmed including the seat, steering
column, and outside rearview mirror position.
If your vehicle has the base audio system, the following
information explains the vehicle personalization on
your vehicle.
If your vehicle has the Navigation system, see
“Personalization” in the Index of the Navigation System
manual for information on vehicle personalization.
If your vehicle is equipped with the ability to program
additional personalization features, the driver’s
preferences are recalled by pressing any button on
the keyless access transmitter, 1 or 2 or by selecting
Driver 1 or 2 on the radio display. Certain features can
be programmed not to recall until the ignition is
turned off.
To change feature preferences, use the following
procedure.
