2008 CADILLAC STS fuse

If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is open or
not closed completely, the security light will ash for
60 seconds and then turn off. At this time, the
theft-deterrent system is armed but the alarm will not
sound if the trunk lid, hood or door that was not closed
completely is tampered with or opened. The alarm
will sound for the trunk lid, hood or a door that was
completely closed at the time the vehicle was locked
using the keyless access transmitter.
The vehicle can be programmed to automatically unlock
the doors and disarm the theft-deterrent system when
you approach the vehicle and the keyless access
transmitter is with you. SeeVehicle Personalization
on page 2-60.
Pressing the unlock button on the keyless access
transmitter or using the key to unlock the driver’s door
disarms the theft-deterrent system. Unlocking a door any
other way while the system is armed will activate the
alarm.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 keyless access transmitter and close the
door. Wait about 30 seconds until the security light
goes off.
3. Reach in and open the door using the inside door
handle. The horn will sound and the exterior lamps
will ash.
You can turn off the alarm by pressing the unlock button
on the keyless access transmitter or by starting the car.
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 5-117. 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.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
2-24

If the vehicle does not start and the keyless access
transmitter appears to be undamaged, try another
keyless access transmitter. Or, you may try placing the
transmitter in the transmitter pocket. See “NO FOBS
DETECTED” underDIC Warnings and Messages
on page 3-80for additional information. At this time,
you may also want to check the fuse. SeeFuses and
Circuit Breakers on page 5-117. If the engine still
does not start with the other transmitter, your vehicle
needs service. If the engine does start, the rst
transmitter may be faulty. See your dealer/retailer
who can service the theft-deterrent system and have
a new keyless access transmitter programmed to
the vehicle.
It is possible for the immobilizer system to learn new
or replacement keyless access transmitters. Up to
4 keyless access transmitters can be programmed for
the vehicle. To program additional transmitters, see
“Matching transmitter(s) to Your Vehicle” underKeyless
Access System Operation on page 2-6.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.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:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer (Vehicles With Heavy Duty Cooling) on
page 4-34orTowing a Trailer (Vehicles Without
Heavy Duty Cooling) on page 4-40for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.

Raise or lower the lever until the arrow starts to ash
to signal a lane change. Hold it briey until the lane
change is complete. The arrow will automatically ash
three times The lever returns to its original position
when it is released.
Rapid ashing of arrows when signaling for a turn
or lane change can be caused by a burned-out signal
bulb. Other drivers will not see the signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse for burned-out bulbs
if the arrow fails to work when signaling a turn.
SeeFuses and Circuit Breakers on page 5-117
