2005 CADILLAC CTS V ECU

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.
This 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
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-38.

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 5-96. 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.

2-19

Immobilizer Operation
Your vehicle is equipped
with a passive
theft-deterrent system.
The system works when you turn the key to ON. The
key uses a transponder that matches an immobilizer
control unit in your vehicle. The correct key will start the
vehicle. If the key is ever damaged, you may not be
able to start your vehicle.
When trying to start the vehicle, if the engine does not
start and the security light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse. SeeFuses
and Circuit Breakers on page 5-96. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the rst key may be
faulty. See your dealer who can service the
theft-deterrent system to have a new key made.
It is possible for the theft-deterrent system decoder to
learn the transponder value of a new or replacement
key. Up to 10 additional keys may be programmed for
the vehicle. This procedure is for learning additional
keys only.
Canadian Owners:If you lose or damage your keys,
only a GM dealer can service the theft-deterrent system
to have new keys made. To program additional keys
you will require two current driver’s keys. You must add
a step to the following procedure. After Step 2, repeat
Steps 1 and 2 with the second current driver’s key. Then
continue with Step 3.
To program a new key do the following:
1. Verify that the new key has PK3+ stamped on it.
2. Insert the current driver’s key in the ignition
and start the engine. If the engine will not start see
your dealer for service.
2-20

3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to ON
within ten seconds of removing the previous key.
5. The security light will turn off once the key has been
programmed. It may not be apparent that the
security light went on due to how quickly the key is
programmed.
6. Repeat the Steps 1 through 4 if additional keys are
to be programmed.
If you are ever driving and the security light comes on
and stays on, you will be able to restart your engine
if you turn it off. The theft-deterrent system, however, is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Cadillac Roadside Service
®.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run
if you follow these guidelines for the rst
500 miles (805 km):
Do not drive at any one speed, fast or slow.
Do not exceed 70 mph (113 km/h).
Do not make full-throttle starts; also refrain
from using the full throttle while driving.
If these procedures are not followed, your engine,
axle, or other parts could be damaged.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this break-in guideline every
time you get new linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-40for more information.
