2006 CADILLAC DTS cruise control

Alerting the Driver
The Adaptive Cruise
Control alert symbol is
located on the display at
the top of the instrument
panel to the right of
the driver.
The alert symbol will ash and a warning beep will
sound when driver action may be required. If Adaptive
Cruise Control is engaged, the alert symbol will
ash when:
Adaptive Cruise Control cannot apply sufficient
braking because you are approaching a vehicle
too rapidly.
The vehicle speed drops below about
20 mph (32 km/h).
A temporary condition prohibits Adaptive Cruise
Control from operating. SeeDIC Warnings and
Messages on page 3-76for more information.
A malfunction is detected in the system. SeeDIC
Warnings and Messages on page 3-76for more
information.
SeeDefensive Driving on page 4-2.
{CAUTION:
Adaptive Cruise Control has only limited
braking ability to slow your vehicle. In some
cases, Adaptive Cruise Control may not have
time to slow your vehicle enough to avoid a
collision. Be ready to take action and apply the
brakes yourself. SeeDefensive Driving on
page 4-2.
Approaching and Following a Vehicle
The Vehicle Ahead symbol is located on the top of the
instrument panel to the right of the driver.
The Vehicle Ahead symbol will only appear when a
vehicle is detected in your path.
3-25

If this symbol does not appear, or disappears briey,
Adaptive Cruise Control will not respond to vehicles you
may see ahead.
{CAUTION:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not detect
a vehicle ahead. Adaptive Cruise Control may
not have time to slow your vehicle enough to
avoid a collision. Do not use Adaptive Cruise
Control when the radar is blocked by snow,
ice, or dirt. Keep your radar clean. See
“Cleaning the System” later in this section.
Adaptive Cruise Control will automatically slow your
vehicle down when approaching a slower moving
vehicle. It will then adjust your speed to follow the
vehicle in front at the selected follow distance. Your
speed will increase or decrease to follow the vehicle
in front of you but will not exceed the set speed. It may
apply limited braking, if necessary. When braking is
active, your brake lights will come on. Braking may
feel or sound different than if you were applying
the brakes yourself. This is normal.
Stationary or Very Slow-Moving Objects
{CAUTION:
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. You could crash
into an object ahead of you. Do not use
Adaptive Cruise Control when approaching
stationary or slow-moving vehicles or other
objects.
{CAUTION:
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. Your vehicle may
accelerate toward objects, such as a stopped
vehicle that suddenly appears after the lead
vehicle changes lanes. Your complete attention
is always required while driving and you should
be ready to take action and apply the brakes.
3-26

Low-Speed Deactivation
If your speed falls below 20 mph (32 km/h) while
following a vehicle ahead, Adaptive Cruise Control will
begin to disengage. The Driver Alert symbol will
ash and the warning beep will sound. The driver must
take action since Adaptive Cruise Control will not
slow the vehicle to a stop.
Passing a Vehicle/Adaptive Cruise
Control Override
If you need to increase speed to pass a vehicle,
use the accelerator pedal. While you are doing this,
the system will not automatically apply the brakes.
A message will appear on the DIC. SeeDIC Warnings
and Messages on page 3-76. Once you remove
your foot from the accelerator pedal, Adaptive Cruise
Control will return to normal operation and be able
to apply the brakes, if needed.
{CAUTION:
If you rest your foot on the accelerator pedal,
the system will not automatically apply the
brakes. You could crash into a vehicle ahead
of you. Do not rest your foot on the accelerator
pedal when using Adaptive Cruise Control.
Curves in the Road
{CAUTION:
Due to Adaptive Cruise Control limitations in
curves, it may respond to a vehicle in another
lane, or may not have time to react to a vehicle
in your lane. You could crash into a vehicle
ahead of you, or lose control of your vehicle.
Give extra attention in curves and be ready
to use the brakes if necessary. Select an
appropriate speed while driving in curves.
Adaptive Cruise Control may operate differently in a
sharp curve. It may reduce your speed if the curve is
too sharp.
3-27

When following a vehicle and entering a curve, Adaptive
Cruise Control could lose track of the vehicle in your
lane and accelerate your vehicle. When this happens the
Vehicle Ahead symbol will not appear.Adaptive Cruise Control may detect a vehicle that is not
in your lane and apply the brakes.
Adaptive Cruise Control may, occasionally, provide
a driver alert and/or braking that you consider
unnecessary. It could respond to signs, guardrails, and
other stationary objects when entering or exiting a
curve. This is normal operation. Your vehicle does not
need service.
3-28

Highway Exit Ramps
{CAUTION:
Adaptive Cruise Control may lose track of the
vehicle ahead and accelerate up to your set
speed while entering or on highway exit ramps.
You could be startled by this acceleration and
even lose control of the vehicle. Disengage
Adaptive Cruise Control before entering a
highway exit ramp. Do not use Adaptive Cruise
Control while entering or on exit ramps.
Other Vehicle Lane Changes
If another vehicle enters the same lane as you, Adaptive
Cruise Control will not detect the vehicle until it is
completely in the lane. Be ready to take action and apply
the brakes yourself.
Using Adaptive Cruise Control on Hills
and When Towing a Trailer
How well Adaptive Cruise Control will work on hills and
when towing a trailer depends on your speed, vehicle
load, traffic conditions and the steepness of the hills.
It may not detect a vehicle in your lane while driving
on hills. When going up steep hills, you may want to use
the accelerator pedal to maintain your speed. When
going downhill, especially when towing a trailer, you may
want to brake to keep your speed down. Applying the
brake disengages the system. You may choose not
to use Adaptive Cruise Control on steep hills, especially
when towing a trailer.
3-29

Disengaging Adaptive Cruise Control
To disengage the system, apply the brake pedal, press
the cancel button, or press the Adaptive Cruise
Control button.
Erasing Set Speed Memory
When you press the Adaptive Cruise Control button or
turn the ignition off, the set speed memory is erased.
Other Messages
There are three additional messages that may appear
on the DIC. They are SERVICE RADAR CRUISE,
RADAR CRUISE NOT READY and CLEAN RADAR.
These messages will appear to indicate a problem with
the Adaptive Cruise Control. SeeDIC Warnings and
Messages on page 3-76for more information.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean the
lens. Remember, do not use Adaptive Cruise Control
in icy conditions, or when visibility is low, such as in fog,
rain or snow.
The emblem/lens is located in the center of the grille.
To clean the emblem/lens, wipe the surface with a
soft cloth. After cleaning the emblem/lens, try to engage
the Adaptive Cruise Control. If you are unable to do
so, see your dealer.
Exterior Lamps
The exterior lamps control
is located on the
instrument panel to the
left of the steering wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
Fog Lamps
The exterior lamps control has four positions:
O(Off):Turn the control to this position to turn off the
exterior lamps except for Daytime Running Lamps (DRL).

The front display is located on top of the instrument
panel to the right of the driver. The rear display is
located near the rear window and can be seen by
looking over your right shoulder. The rear display has
three color-coded lights. The front display will have
either three or six lights depending on whether
your vehicle is equipped with Adaptive Cruise Control
(ACC). If your vehicle has ACC, it will have three lights
along with the ACC lights. If your vehicle does not
have ACC, it will have six UFRPA lights.The UFRPA lights are used to provide distance and
system information, along with beeps played out either
the front or rear speakers. For objects detected near
the front bumper, high-toned beeps will be played
out the front speakers. For objects detected near the
rear bumper, low-toned beeps will be played out the
rear speakers.
How the System Works
When the vehicle is started, the front display will
briey illuminate to let you know the display is
operating correctly. When the shift lever is moved into
REVERSE (R), the rear display will briey illuminate
to let you know the display is operating correctly.
UFRPA comes on automatically when the shift lever is
moved out of PARK (P). The system does not work
at a forward speed greater than 5 mph (8 km/h), so
the front display indicators are turned off. The system
also does not work at a reverse speed greater than
5 mph (8 km/h). To remind you of this, the red light on
the rear display will ash.
The system can be disabled using the Driver Information
Center (DIC). SeeDIC Controls and Displays on
page 3-72. Front Parking Assist

How the System Works when
Moving Forward
When moving forward, the system detects objects only
near the front bumper.
If an object is detected at a forward speed of less
than 5 mph (8 km/h), or if you are already within a
4 ft (1.2 m) distance to a detected object when
UFRPA rst comes on, the following describes what
will occur according to your distance from an object
located in front of the vehicle:
At distances between 40 inches (1 m) and
4 ft (1.2 m), two amber lights will be lit. If you
have Adaptive Cruise Control, a single amber
light will be lit.
At distances between 23 inches (0.6 m) and
40 inches (1 m), four amber lights will be lit.
If you have Adaptive Cruise Control, two amber
lights will be lit.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all six lights (four amber lights/
two red lights) will be lit. If you have Adaptive Cruise
Control, all three lights (amber/amber/red) will be lit.
At distances less than 12 inches (0.3 m), a chime will
sound for a short time and all six lights (four amber
lights/two red lights) will be lit and ashing. If you
have Adaptive Cruise Control, a chime will sound for
a short time and all three lights (two amber lights/
one red light) will be lit and ashing.
How the System Works when Backing
When backing, UFRPA detects objects close to the
front and rear bumpers. The rst time an object
is detected a single chime will sound. If an object is
detected at a REVERSE (R) speed of less than 5 mph
(8 km/h), or if you are already within an 8 ft (2.5 m)
distance to a detected object when the system
rst comes on, the following describes what will occur
according to your distance from an object located behind
the vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will be lit.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be lit.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/amber/red)
will be lit.
At distances less than 12 inches (0.3 m), a chime
will sound for a short time and all three lights
(amber/amber/red) will be lit and ashing.
