2004 CADILLAC CTS V ECU

{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 side impact airbag for the right front passenger and
the person seated directly behind that passenger is in
the ceiling above the side windows.
{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.

Programmable Automatic
Door Locks
If your vehicle has an automatic transmission, your
vehicle is programmed so that when the doors
are closed, the ignition is on and the shift lever is
moved out of PARK (P), all the doors will lock. The
doors will unlock every time you stop the vehicle and
move the shift lever back into PARK (P).
If your vehicle has a manual transmission, the vehicle is
programmed so that the doors will lock automatically
after the vehicle speed reaches 5 mph (8 km). The doors
will not automatically unlock until the ignition is turned
off and the key is removed from the ignition switch.
If someone needs to exit the vehicle once the doors are
locked, have that person use the manual lever or
power door lock switch. When the door is closed again,
it will not lock automatically. Use the manual lever or
the power door lock switch to lock the door.
The power door locks can be programmed through
prompts displayed on the Driver Information
Center (DIC). These prompts allow you to choose
various lock and unlock settings. For more information
on programming, seeDIC Vehicle Personalization
on page 3-88.
Rear Door Security Locks
Your vehicle is equipped with rear door security locks
that prevent passengers from opening the rear doors on
your vehicle from the inside.
The rear door security
locks are located on the
inside edge of each
rear door. You must
open the rear doors to
access them.
To use these locks, do the following:
1. Insert your key into the slot next to the rear door
security lock label and turn it to engage the lock.
2. Close the door.
3. Repeat the steps for the other rear door.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.
2-10

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, the front door power lock switch or
by lifting the rear door manual lock.
2. Then open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert your key into the slot next to the rear
door security lock label and turn it to disengage
the lock.
3. Repeat the steps for the other lock.
The rear door locks will now work normally.Lockout Protection
If you press the power door lock switch when the key is
in the ignition and any door is open, all the doors will
lock and only the driver’s door will unlock. If you
close the doors, you can lock them using the remote
keyless entry transmitter. Be sure to remove the
key from the ignition when locking your vehicle.
The anti-lockout feature can be overridden by pressing
the lock button on the remote keyless entry transmitter
or by pressing the power lock switch a second time.

trunk release handle.
3. Pull forward on the trunk release handle to open

Rear-Seat Pass Through
If your vehicle is equipped with the rear seat-pass
through door, you can access the trunk without opening
the trunk lid. This is especially useful when transporting
long items.
To open the door, pull down the rear seat armrest. Then
pull the lever all the way down to release the door.
To close the panel, push the door up and back
into place. Then try to open the door without pulling up
on the lever to make sure it is locked into place.
Emergency Trunk Release Handle
Notice:Using the emergency trunk release handle
as a tie-down or anchor point when securing
items in the trunk may damage it. Use the
emergency trunk release handle only to help you
open the trunk lid.
There is a glow-in-the-dark emergency trunk release
handle located on the back wall of the trunk. This handle
will glow following exposure to light. Pull the release
handle toward the front of the vehicle to open the trunk
from the inside.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Theft-Deterrent System
If your vehicle has this
feature, the security light is
located on the instrument
panel cluster.
If the ignition is off and a door is open, the security
light will ash, reminding you to arm the
theft-deterrent system.
To arm the system, do the following:
1. Lock the door using the remote keyless entry
transmitter or the power door lock switch.
2. Close all the doors. The security light will illuminate.
It should go off within approximately 30 seconds.
Your security system is now armed.If a door or a trunk is opened without a key or a remote
keyless entry transmitter, the horn will sound and the
lamps will ash for up to 30 seconds.
The theft-deterrent system won’t arm if you lock the
doors with a key or use the manual door lock. It
activates only if you use the remote keyless entry
transmitter or the power lock on the door.
To avoid activating the alarm by accident do
the following:The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don’t want to arm the theft-deterrent system.
Always unlock a door with a key or use the remote
keyless entry transmitter. Pressing the unlock
button on the remote keyless entry transmitter
disables the theft-deterrent system. Unlocking a
door any other way will activate the alarm when a
door or the trunk is opened.
If you activate the alarm by accident, unlock the driver’s
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter, or by starting the vehicle with a valid key.
2-18

Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock switch
or the remote keyless entry transmitter and
close the door. Wait approximately 30 seconds until
the security light goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the exterior lamps will ash.
You can turn off the alarm by unlocking the driver’s door
with your key, using the unlock button on the remote
keyless entry transmitter or by starting the car with
a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown. To
replace the fuse, seeFuses and Circuit Breakers on
page 5-100. If the fuse does not need to be replaced, you
may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.
