The security light will come on if there is a problem with
arming or disarming the theft-deterrent system.
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, there may be a
problem with your theft-deterrent system. Turn the
ignition off and try again.
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, see Fuses and
Circuit Breakers
on page 6‑104. If the engine still does
not start with the other key, your vehicle needs service.
If your vehicle does start, the first key may be faulty.
See your dealer 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 10 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 or a locksmith
who can service PASS-Key
®III+ to have keys made
and programmed to the system. See your dealer 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 for service.
3. After the engine has started, turn the key to LOCK/OFF, and remove the key.
4. Insert the new key to be programmed and turn it to the ON/RUN position within five seconds of turning
the original key to LOCK/OFF.
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 lose or damage your PASS-Key
®III+ key,
see your dealer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

A (STOPPING THE ENGINE/LOCK/OFF):When the
vehicle is stopped, turn the ignition switch to LOCK/OFF
to turn the engine off. Retained Accessory Power (RAP)
will remain active. See Retained Accessory Power
(RAP) on page 3‑24.
This is the only position in which the ignition key can be
inserted or removed. This position locks the ignition and
transmission and steering column.
Do not turn the engine off when the vehicle is moving.
This will cause a loss of power assist in the brake and
steering systems and disable the airbags.
In an emergency:
1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This may deplete
power assist, requiring increased brake pedal
force.
2. Shift the vehicle to neutral. This can be done while the vehicle is moving. After shifting to neutral,
firmly apply the brakes and steer the vehicle to a
safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition to LOCK/OFF. On vehicles with
an automatic transmission, the shift lever must
be in P (Park) to turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake
on
page 3‑29. The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from right to
left while turning the key to ACC/ACCESSORY. If this
doesn't work, the vehicle needs service.
B (ACC/ACCESSORY):
This position lets the radio
and windshield wipers operate while the engine is off.
To use ACC/ACCESSORY, turn the key clockwise.
C (ON/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 ACC/ACCESSORY or ON/RUN position with the
engine off. You may not be able to start the 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 door is opened if the ignition is in LOCK/OFF,
ACC/ACCESSORY and the key is in the ignition. See
DIC Warnings and Messages
on page 4‑65for more
information.

3 (Third):This position is also used for normal driving.
However, it reduces vehicle speed more than D (Drive)
without using the brakes. You might choose 3 (Third)
instead of D (Drive) when driving on hilly, winding roads,
when towing a trailer, so there is less shifting between
gears and when going down a steep hill.
2 (Second): This position reduces vehicle speed more
than 3 (Third) without using the brakes. You can use
2 (Second) on hills. It can help control vehicle speed as
you go down steep mountain roads, but then you would
also want to use the brakes off and on.
Notice: Do not shift into 2 (Second) unless you are
going slower than 65 mph (105 km/h), or you can
damage the engine and/or transmission.
1 (First): This position reduces vehicle speed even
more than 2 (Second) without using the brakes. You can
use it on very steep hills, or in deep snow or mud. If the
shift lever is put in 1 (First) while the vehicle is moving
forward, the transmission will not shift into first 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 transmission. The repair will not be
covered by the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.Performance Shifting
If the vehicle has this feature, it can detect a change in
driving patterns. If you make an aggressive driving
maneuver, the vehicle's transmission 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 door.
To set the parking brake, hold the regular brake pedal
down, then push the parking brake pedal down.
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 the vehicle serviced.
3-29
Black plate (30,1)Cadillac DTS Owner Manual - 2011
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 4‑50for more
information.
To release the parking brake, hold the regular brake
pedal down, then push the parking brake pedal down.
When you lift your foot off the parking brake pedal, the
pedal will follow your foot 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. Make sure
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,
see Towing a Trailer on page 5‑26.
Shifting Into Park
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, use the steps that follow.
If you are pulling a trailer, see Towing a Trailer
on
page 5‑26
.
Steering Column Shift Lever
If the vehicle has a steering column shift lever, use this
procedure to shift the vehicle into P (Park):
1. Hold the brake pedal down.
2. Move the shift lever into P (Park) by pulling the shift lever toward you and moving it up as far as it
will go.
3. With your foot still holding the brake pedal down, set the parking brake. See Parking Brake
on
page 3‑29for more information.

Compass
Compass Operation
PressOorAUTO 3, depending on the vehicle, to
turn the compass on or off.
When the ignition and the compass feature are on, after
a few seconds, the mirror will display the compass
heading. The compass automatically calibrates as the
vehicle is driven.
Compass Calibration
If after a few seconds, the display does not show the
correct direction, (for example, N for North), there may
be a strong magnetic field interfering with the compass.
Interference can be caused by a magnetic antenna
mount, magnetic note pad holder or a similar
magnetic item.
The compass can be placed in calibration mode
manually by pressing and holding
OorAUTO 3,
depending on the vehicle, until a C is shown in the
compass display.
The compass can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.

{WARNING:
The Ultrasonic Front and Rear Park Assist
(UFRPA) system does not replace driver vision.
It cannot detect:
.objects that are below the bumper, underneath
the vehicle, or if they are too close or far from
the vehicle
.children, pedestrians, bicyclists, or pets.
If you do not use proper care before moving
forward and while backing; vehicle damage, injury,
or death could occur. Even with UFRPA, always
check in front of the vehicle before moving
forward and behind the vehicle before backing up.
While moving forward and backing, be sure to
look for objects and check the vehicle's mirrors.
Front Parking Assist Display
Rear Parking AssistDisplay
The front display is located on top of the instrument
panel to the right of the driver. The front display will
have either three or six lights to provide distance and
system information. With Adaptive Cruise control (ACC),
it will have three lights along with the ACC lights.
Without ACC, it will have six lights. High-toned beeps
from the front speakers are for objects detected near
the front bumper.
The rear display is located near the rear window and
can be seen by looking over your right shoulder. The
rear display uses three color-coded lights to provide
distance and system information. Low-toned beeps from
the rear speakers are for the rear bumper.
3-39
Black plate (40,1)Cadillac DTS Owner Manual - 2011
How the System Works
UFRPA comes on automatically when the shift lever is
moved out of P (Park). The system does not work at a
forward or reverse speed greater than 5 mph (8 km/h).
To be detected, objects must be at least 25.4 cm (10 in.)
off the ground and below hood or trunk level. Objects
must also be within 1.2 m (4 ft.) in front of the vehicle
and 2.5 m (8 ft.) from the rear bumper. This distance
may be less during warmer or humid weather.
When backing up, if objects are detected at the same
time near both the front and rear bumpers, both
color-coded light displays will notify you of objects close
to each bumper. If there are objects detected near both
bumpers, the beeps will only be sounded to notify that
objects are close to the rear bumper. However, if while
the vehicle is backing up and an object comes within
0.3 m (1 ft.) of the front bumper, and at the same time
there is another object further than 0.3 m (1 ft.) from the
rear bumper, then the beeps will only be sounded to
notify you of the closer object that is near the front
bumper.
The system can be disabled using the Driver
Information Center (DIC). See“Parking Assist”under
DIC Operation and Displays
on page 4‑60for more
information.
Moving Forward
When the vehicle is started, the front display will briefly
illuminate to let you know the system is working.
The following describes what will occur with the front
display as you get closer to a object detected in the
front of the vehicle:

The system can be disabled through the Driver
Information Center (DIC). See
“Parking Assist”under
DIC Operation and Displays
on page 4‑60for more
information.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and 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 driver disables the system.
.The ultrasonic sensors are not clean. Keep the
vehicle's rear bumper free of mud, dirt, snow, ice
and slush. For cleaning instructions, see Washing
Your Vehicle on page 6‑98.
.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.
.A tow bar is attached to the vehicle.
.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 25 km/h (15 mph), take the vehicle to your dealer.
