Theft-Deterrent Systems
This vehicle has theft-deterrent features, however, they
do not make it impossible to steal.
Theft-Deterrent System
Your vehicle has a theft-deterrent alarm system.
The security light is
located on the instrument
panel cluster.
If the ignition is off and a door is open, the security light
will flash, reminding you to arm the theft-deterrent
system.
To arm the system:
.Press the lock button on the keyless access
transmitter. If the door is closed when the lock
button is pressed, the security light will stay
illuminated for 30 seconds. After the security light
goes off, the theft‐deterrent system is armed.
Pressing the lock button twice will arm the system
immediately. 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 flash for 60 seconds and then turn off. 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.
.Exit the vehicle and lock the door with the power
door lock switch or lock button on the keyless
access transmitter. The security light should flash.
Close the door. The security light will stop flashing
and stay on. After 30 seconds the light should turn
off, the theft‐deterrent system is armed.
.If Passive Arming is activated through the vehicle
personalization feature, the system will arm
automatically after you close the door and take
at least one keyless access transmitter with you.
The security light will turn on. After 60 seconds the
light should turn off. The theft-deterrent system is
armed. See
Vehicle Personalization
on page 3‑59.

Black plate (23,1)Cadillac STS Owner Manual - 2011
If a door, hood, or the trunk is opened without the
keyless access transmitter, the horn will sound for
30 seconds and the lamps will flash for two minutes.
The vehicle cannot be started without a keyless access
transmitter.
The Theft-Deterrent system will not arm if :
.The key is used to turn the key cylinder to the lock
position.
.The driver's door is locked using the power door
lock switch after the doors are closed.
The vehicle can be programmed to automatically unlock
the doors and disarm the theft‐deterrent system when

will flash.
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, see Fuses and Circuit Breakers
on
page 6‑115. 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.

How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). The rear display briefly
illuminates to indicate the system is working.
URPA operates only at speeds less than 3 mph
(5 km/h). If the vehicle is above this speed, the red light
on the rear display will flash.
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below trunk level. Objects
must also be within 5 feet (1.5 m) from the rear bumper.
This distance may be less during warmer or humid
weather.
A single beep will sound the first time an object is
detected between 20 inches (0.5 m) and 5 feet (1.5 m)
away. Beeping will occur when the vehicle is closer than
20 inches (0.5 m) from the object.The following describes what will occur with the URPA
display as the vehicle gets closer to a detected object:
Description English Metric
amber light 5 ft 1.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights/ continuous beep 20 in 0.5 m
amber/amber/red lights flashing and
continuous beep 1 ft 0.3 m

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition a red light will be shown on the rear URPA
display when the shift lever is moved into R (Reverse).
This occurs under the following conditions:
.The ultrasonic sensors are not clean. Keep the
vehicle's rear bumper free of mud, dirt, snow, ice
and slush. For cleaning instructions, seeWashing
Your Vehicle on page 6‑109.
.A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during the
last drive cycle, the red light may illuminate in the
rear display. Once the attached object is removed,
URPA will return to normal operation.
.The vehicle's bumper is damaged. Take the vehicle
to your dealer to repair the system.
.Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 15 mph (25 km/h), take the vehicle to your dealer.

Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery's temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery's state of charge is low, the voltage is
raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gauge or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following are on, such as: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at high
speed, heated seats, engine cooling fans, trailer loads,
and loads plugged into accessory power outlets. EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator's output
and the vehicle's electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER ACTIVE
or BATTERY VOLTAGE LOW. If this message is
displayed, it is recommended that the driver reduce the
electrical loads as much as possible. See
DIC Warnings
and Messages on page 4‑76.
Inadvertent Power Battery Saver
This feature is designed to protect the vehicle's battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, or the garage door opener. When the
ignition is turned off, the power to these features will
automatically turn off after 10 minutes (three minutes if a
new car has 24 km (15 miles) or less). Power will be
restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy lamp switch
is turned on.
