2007 CADILLAC DTS PROFESSIONAL door lock

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 a power door lock
with the door open or the RKE transmitter.
To avoid activating the alarm by accident:
Lock the vehicle with the door key or the
manual door lock after the doors are closed.
Always unlock a door with a key or use the
RKE transmitter system. 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 system, or by starting the car
with a valid key.
Changes or modications made to this system by
other than an authorized service facility could
void authorization to use the theft system.
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 or the RKE system and close the
door. Wait 30 seconds until the security lamp
goes off.
3. Reach in and unlock the door using the
manual lock and open the door. The horn
will sound and the hazard lights will ash.
You can turn off the alarm by unlocking the driver’s
door with your 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 452. 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.

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
Notice:Using a tool to force the key from the
ignition switch could cause damage or
break the key. Use the correct key and turn the
key only with your hand. Make sure the key
is in all the way. If none of this works,
then your vehicle needs service.A (OFF):This is the only position in which the
ignition key can be inserted or removed. This
position locks the ignition and transaxle. It is a
theft-deterrent feature.
B (ACCESSORY):This position lets the radio and
windshield wipers operate while the engine is
off. To use ACCESSORY, turn the key clockwise.
C (RUN):This position is where the key returns
to after the vehicle is started. This position displays
some of the warning and indicator lights.
The battery could be drained if you leave the key
in the ACCESSORY or RUN position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver
Information Center (DIC) will display DRIVER
DOOR OPEN when the driver’s door is opened if
the ignition is in OFF, ACCESSORY and the
key is in the ignition. SeeDIC Warnings
and Messages on page 246for more information.

Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transaxle. Also, always remember
to lock the doors.
The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the ignition key is turned off:
Audio System
Audio Steering Wheel Controls
Power Windows
SunroofPower to these accessories will work up to
10 minutes or until the driver’s door is opened. For
an additional 10 minutes of power, close all the
doors and turn the key to RUN and then back
to OFF.
Starting the Engine
Place the transaxle in the proper gear.
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position – this is a safety feature. To
restart when you are already moving, use
NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as your engine gets warm. Do not
race the engine immediately after starting it.

Cornering Lamps
The cornering lamps come on when the
headlamps or parking lamps are on and you
signal a turn with the multifunction lever.
They provide more light for cornering.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have
been left on, the exterior lamps will turn off
approximately 10 minutes after the ignition is
turned to OFF. This protects against draining
the battery in case you have accidentally left the
headlamps or parking lamps on. The battery saver
does not work if the headlamps are turned on
after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to
turn the lamps back on.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel
lights.
The button for this control is located below the
exterior lamps control.
Push the button in and release to extend the button.
Turn the button clockwise for brightness of the
instrument panel lights and counter clockwise to
turn the brightness down.
Courtesy Lamps
The courtesy lamps are located on the headliner
above the rear seat. These lamps come on by
turning the instrument panel brightness knob fully
clockwise or when any door is opened and it is
dark outside. Puddle lamps are located on
the bottom of the front and rear door trim.
Professional vehicles have an additional dome
lamp and also opera lamps.
199

Entry Lighting
This feature turns on the courtesy lamps and the
backlighting to the door switches and to the exterior
lamp control when a door is opened or if you press
the remote keyless entry transmitter unlock button.
If activated due to the transmitter, the lighting will
remain active for about 40 seconds. Since the entry
lighting system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn
on. The courtesy lamps turn off approximately
25 seconds after the last door is closed. They will
dim to off if the ignition key is turned to RUN, or
immediately deactivate if the power locks are
activated.
Parade Dimming
This feature prohibits dimming of the digital
displays and backlighting during daylight hours
when the key is in the ignition and the headlamps
are on. This feature is fully automatic. When
the light sensor reads darkness outside and the
parking lamps are active, the digital displays
can be adjusted by turning the instrument panel
brightness knob counterclockwise to dim and
clockwise to brighten lighting.
Reading Lamps
The reading lamps are located on the overhead
console on the headliner and in the rear door
opening. These lamps come on automatically
when any door is opened and it is dark outside.
For manual operation, press the button to
turn them on. Press it again to turn them off.
If the reading lamps are left on, they automatically
shut off 10 minutes after the ignition has been
turned off.
Battery Load Management
The battery load management feature is
designed to monitor the vehicle’s electrical
load and determine when the battery is in a
heavy discharge condition. During times of high
electrical loading, the engine may idle at a higher
revolutions per minute (rpm) setting than normal
to make sure the battery charges. High electrical
loads may occur when several of the following are
on: headlamps, high beams, fog lamps, rear
window defogger, the climate control fan at high
speeds, heated seats and engine cooling fans.
