2004 Cadillac CTS/CTS-VOwner ManualM

Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3
Climate Controls in Section 3

{CAUTION:
Anyone who is up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Airbags plus lap-shoulder
belts offer the best protection for adults, 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 your vehicle. To read how,
seeOlder Children on page 1-29orInfants and
Young Children on page 1-32.
There is an airbag
readiness light on the
instrument panel, which
shows the airbag symbol.The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAirbag Readiness Light on page 3-42
for more information.Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
1-50

The right front passenger’s frontal airbag is in the
instrument panel on the passenger’s side.The driver’s seat-mounted side impact airbag is in the
side of the driver’s seatback closest to the door.
1-51

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
the angle of the impact and how quickly the vehicle
slows down in frontal and near-frontal impacts. For side
impact airbags, ination is determined by the location
and severity of the impact.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. For both
frontal and side impact airbags, the sensing system
triggers a release of gas from the inator, which inates
the airbag. The inator, airbag and related hardware
are all part of the airbag modules inside the steering
wheel, instrument panel, the side of the front seatbacks
closest to the door and the ceiling of the vehicle,
near the side windows.
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. The airbag supplements the protection
provided by safety belts. Airbags distribute the force
of the impact more evenly over the occupant’s
upper body, stopping the occupant more gradually.
But the frontal airbags would not help you in many types
of collisions, including rollovers, rear impacts, and
many side impacts, primarily because an occupant’s
motion is not toward the airbag. Side impact airbags
would not help you in many types of collisions, including
frontal or near frontal collisions, rollovers, and rear
impacts, primarily because an occupant’s motion is not
toward those airbags. Airbags should never be
regarded as anything more than a supplement to safety
belts, and then only in moderate to severe frontal or
near-frontal collisions for the driver’s and right front
passenger’s frontal airbags, and only in moderate to
severe side collisions for the side impact airbags.

What Will You See After an
Airbag Inates?
After the airbag inates, it quickly deates,
so quickly that some people may not even realize
the airbag inated. Some components of the airbag
module — the steering wheel hub for the driver’s airbag,
the instrument panel for the right front passenger’s
bag, the side of the seatback closest to the door for the
seat-mounted side impact airbags and the area along
the ceiling of your vehicle near the side windows — will
be hot for a short time. The parts of the bag that
come into contact with you may be warm, but not too
hot to touch. There will be some smoke and dust coming
from the vents in the deated airbags. Airbag ination
does not prevent the driver from seeing or being able to
steer the vehicle, nor does it stop people from leaving
the vehicle.
{CAUTION:
When an airbag inates, there is 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
can not 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.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the
airbags inate (if battery power is available). You can
lock the doors again and turn the interior lamps off
by using the door lock and interior lamp controls.
The hazard warning ashers will also come on when the
airbags deploy. If you want to turn them off, press the
hazard warning asher button twice.
1-56

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 7-9.
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.
