2006 CADILLAC CTS trunk

The theft-deterrent system will not arm if you lock the
doors with a key or use the manual door lock. It
activates only if you use the RKE transmitter or the
power lock on the door.
To avoid activating the alarm by accident do the
following:
Lock the door with the key or the manual door lock
after the doors are closed if you do not want to arm
the theft-deterrent system.
Always unlock a door with a key or use the RKE
transmitter. Pressing the unlock button on the
RKE 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 RKE transmitter, or by
starting the vehicle with a valid key.
Testing the Alarm
1. 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 RKE 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.
The alarm can be turned off by unlocking the driver’s
door with the key, using the unlock button on the
RKE 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 5-104. 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.

Roof Rack
{CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier — like paneling, plywood, a mattress
and so forth — the wind can catch it as you
drive along. This can cause you to lose
control. What you are carrying could be
violently torn off, and this could cause you or
other drivers to have a collision, and of course
damage your vehicle. You may be able to carry
something like this inside. But, never carry
something longer or wider than the luggage
carrier on top of your vehicle.The vehicle has threaded nuts that are covered with a
plastic cap on the roof rails, that indicate the mounting
locations for a roof rack or luggage carrier. Open
the doors to access these locations. Remove the plastic
cap before attaching a roof rack or luggage carrier.
For more information on purchasing the rack/carrier as
well as installation information, contact your dealer.
Convenience Net
The convenience net attaches to the oor and back wall
of the trunk using four anchor points which allows the
net to be used two ways. It can be attached like a
hammock or anchored to lay at across the oor of the
trunk. Put small loads, like grocery bags, behind the
net. It can help keep them from falling over during sharp
turns or quick starts and stops.
The net is not for larger, heavier loads. Store them in the
trunk as far forward as you can. When not using the net,
hook the net to the tabs securing it to the sill plate.
