light CADILLAC DTS PROFESSIONAL 2007 1.G Owner's Manual

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.

PASS-Key®III+
The PASS-Key®III+ system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry
Canada.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1. This device may not cause harmful
interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.PASS-Key
®III+ uses a radio frequency
transponder in the key that matches a decoder in
your vehicle.
PASS-Key®III+ Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent
system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not
have to do anything special to arm or disarm the
system. It works when you insert or remove
the key from the ignition or transition the key from
RUN, ACCESSORY, or START from the off
position.
When the PASS-Key
®III+ system senses that
someone is using the wrong key, it prevents the
vehicle from starting. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of
electrical key codes.
If the engine does not start and the security light
comes on when trying to start the vehicle, the
key may have a damaged transponder. Turn the
ignition off and try again.
115

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 452.Ifthe
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/retailer who
can service the PASS-Key
®III+ to have a new key
made. In an emergency, contact Roadside
Assistance.
It is possible for the PASS-Key
®III+ decoder to
“learn” the transponder value of a new or
replacement key. Up to nine additional keys may be
programmed for the vehicle. The following
procedure is for programming additional keys only.
If all the currently programmed keys are lost or do
not operate, you must see your dealer/retailer or a
locksmith who can service PASS-Key
®III+ to have
keys made and programmed to the system.
See your dealer/retailer or a locksmith who can
service PASS-Key
®III+ to get a new key blank that
is cut exactly as the ignition key that operates the
system.To program the new key:
1. Verify that the new key has a
1stamped
on it.
2. Insert the original, already programmed, key
in the ignition and start the engine. If the
engine will not start, see your dealer/retailer
for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the new key to be programmed
and turn it to the RUN position within
ve seconds of removing the original key.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys
are to be programmed.
If you are driving and the security light comes on
and stays on, you may be able to restart your
engine. Your PASS-Key
®III+ system, however,
may not be working properly and must be serviced
by your dealer/retailer.

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.
118

FIRST (1):This position reduces vehicle speed
even more than SECOND (2) without using your
brakes. You can use it on very steep hills, or in
deep snow or mud. If the shift lever is put in
FIRST (1) while the vehicle is moving forward, the
transaxle will not shift into rst gear until the vehicle
is going slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle. If
you are stuck, do not spin the tires. When
stopping on a hill, use the brakes, or parking
brake to hold the vehicle in place.
Performance Shifting
If your vehicle has this feature, it can detect a
change in driving patterns. If you make an
aggressive driving maneuver, the vehicle’s
transaxle automatically shifts to the lowest possible
gear to maximize vehicle performance. The
vehicle will automatically return to normal operation
when you return to normal driving patterns.
Parking Brake
The parking brake pedal
is located to the left of
the regular brake pedal,
near the driver’s door.
To set the parking brake, hold the regular brake
pedal down with your right foot and push the
parking brake pedal down with your left foot.
If the ignition is on, the brake system warning light
on the instrument panel cluster should come
on. If it does not, you need to have your vehicle
serviced.
125

A warning chime will sound if the parking brake is
set, the ignition is on, and the vehicle speed is
greater than 5 mph (8 km/h). The brake light
will come on and stay on until the parking brake is
released. SeeBrake System Warning Light on
page 229for more information.
To release the parking brake, hold the regular
brake pedal down with your right foot and push the
parking brake pedal down with your left foot.
When you lift your left foot, the parking brake pedal
will follow it to the released position.
Notice:Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake system
parts. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
If you are towing a trailer and are parking on any
hill, seeTowing a Trailer on page 342.Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 342.

compass heading (for example, N for North),
there may be a strong magnetic eld interfering
with the compass. Such interference may be
caused by a magnetic antenna mount, magnetic
note pad holder or a similar magnetic item. If
the letter C should ever appear in the compass
window, the compass may need calibration.
The mirror can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the
display reads a direction.
The compass can be placed in calibration mode
manually by pressing and holding the on/off button
untilaCisshown in the compass display.
