light CADILLAC DTS 2007 1.G Repair Manual

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 (ACC), 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.
205

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.
When you are backing the vehicle and 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 you are backing and an object comes
within 1 ft (0.3 m) of the front bumper, and at the
same time there is another object further than
1 ft (0.3 m) from the rear bumper, then the beeps
will only be sounded to notify you of the closer
object that is near the front bumper.When the System Does Not Seem to
Work Properly
If the UFRPA system will not activate due to a
temporary condition, the message PARKING
ASSIST OFF will be displayed on the DIC and a
red light will be shown on the rear UFRPA display
when the shift lever is moved into REVERSE (R).
This occurs under the following conditions:
The driver disables the system. SeeDIC
Controls and Displays on page 240.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your
trunk during your last drive when you turned off
the vehicle. If the attached objects are removed
from your vehicle before the start of your next
drive, the system will return to normal operation
unless an object is detected when the vehicle is
shifted out of park. If this occurs, you will have
to wait until the vehicle is driven forward above
15 mph (25 km/h) before UFRPA will return to
normal operation.

After the vehicle is started, the display will
show the interior temperature settings and the
outside temperature.
If the AUTO position is selected on the fan or mode
control, the system will automatically control the air
conditioning compressor. The A/C compressor will
run automatically even at cool outside temperatures
in order to dehumidify the air. The A/C indicator
light will be lit when the system is operating
automatically, even at near freezing outside
temperatures. Press the A/C button on the fan
control to turn off the A/C. For improved window
clearing performance in defog or defrost modes,
the A/C compressor will run automatically.
h(AUTO RECIRCULATION):If the AUTO
position is selected on either the fan or mode
control, the system will automatically control the air
inlet to supply fresh outside air or recirculate the
interior air to cool the car faster. The indicator light
on the recirculation button will light whenever the
system switches to recirculation. You may force
outside air by pressing the recirculation button
when the light is lit. For vehicles without rear climate
controls, press the outside air button to force
outside air. The next time AUTO fan or mode is
selected, the air inlet will reset back to AUTO
operation.
Manual Operation
9(Fan):Turn the left control either to the left or
right to adjust the fan speed. Turning this control
completely counterclockwise will turn on the
automatic fan operation. Turning this control to the
“O” position will turn the climate control system off.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment air
lter may need to be replaced. SeePassenger
Compartment Air Filter on page 220.
9(Off):Turn the left control to this position to
turn the entire climate control system off.
To change the current mode, select one of the
following positions using the right control:
AUTO:Turn the control to this position to turn on
the automatic delivery mode operation.
F(Vent):Turn the control to this mode to direct
air to the instrument panel outlets.
*(Bi-Level):Turn the control to this mode to
direct approximately half of the air to the instrument
panel outlets and most of the remaining air to the
oor outlets. In automatic operation, cooler air is
directed to the upper outlets and warmer air to the
oor outlets.
212

7(Floor):Turn the control to this mode to direct
most of the air to the oor outlets with some air
directed to the side window outlets and the
windshield.
The mode control can also be used to select
the oor/defog mode. In this mode, the system
will automatically use outside air. If recirculation
is selected, it will only stay on for three minutes
to reduce windshield fogging. Information on
defogging and defrosting can be found later in
this section.
:(Outside Air):Press this button to allow
outside air to come into the vehicle. It is used to
prevent the air inside the vehicle from becoming
too dry. Press this button to turn the outside
air mode on or off. When the button is pressed,
the indicator light will come on. Pressing the
recirculation button will cancel this mode.
?(Recirculation):Press this button to keep
outside air from coming in the vehicle. It is used
to prevent outside air and odors from entering the
vehicle or to help cool the air inside the vehicle
faster. Press this button to turn the recirculation
mode on or off. When the button is pressed,
an indicator light will come on.
wx(Driver’s Temperature Controls):Press
these buttons next to the fan control to manually
increase or decrease the temperature inside
your vehicle.
wx(Passenger’s Temperature Controls):
Press these buttons next to the mode control to
manually increase or decrease the temperature for
the front passenger. If the passenger’s climate
control system is off, pressing one of these buttons
will turn it on.
PASS (Passenger’s Climate Control):Press
this button to turn the passenger’s climate control
systems on or off. The temperature selected
by the front passenger will also control the rear
system air temperature unless the rear seat
passengers select their own comfort setting.
If the PASS button is pressed to turn the
passenger temperature setting off, the driver’s
temperature knob will control the temperature for
the entire vehicle.
213

AUX:If your vehicle has a rear climate control
system, press this button to turn the rear climate
control fan on for automatic operation. After
the AUX button is pressed, the indicator light
will come on. Press the button again to turn the
auxiliary fan off. SeeRear Climate Control System
on page 218.
#(Air Conditioning):Press the center of the
left control to override the automatic system
and turn the air conditioning system on or off.
When in AUTO, the air conditioning compressor
will come on automatically, as necessary.
The air conditioning system removes moisture from
the air, so you may notice a small amount of water
dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
Sensors
The solar sensor, located in the defrost grille,
middle of the instrument panel, monitors the solar
radiation. Do not cover the solar sensor or the
system will not work properly.
214

Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to
clear fog from your windshield. Use the oor/defog
mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more
quickly.
W(Floor/Defog):Turn the control to this mode
to direct approximately half of the air to the
oor outlets and the remaining air is directed to
the side window outlets and to the windshield.
When you select this mode, the system turns
off recirculation and runs the air conditioning
compressor unless the outside temperature is
at or below freezing. The recirculation mode
cannot be selected while in the oor/defog mode.
0(Defrost):Turn the control to this mode to
direct most of the air to the windshield and the
side window outlets. In this mode, the system will
automatically turn off recirculation and run the
air conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation
cannot be selected while in the defrost mode.
Do not drive the vehicle until all the windows
are clear.
For professional vehicles, air will be allowed to
ow through the rear outlets. For quicker defrost,
press the AUX button on the front climate
control system so that the light is not lit.
216

Rear Climate Control System
If your vehicle has a rear climate-control system,
the rear-seat passengers can use it to adjust
the direction of the airow, the fan speed and
the temperature for the rear-seating area.
This system also works with the main
climate-control system in your vehicle.
The control panel for this system is located on the
back of the center console.If the AUX button located on the front climate
control panel is pressed, the rear climate control
system will be turned on. The rear system will
operate in automatic mode and the temperature
settings selected for the front climate control panel
will also be selected for the rear passengers.
If the rear passenger would like to adjust the
rear climate control system, they can select
a different temperature and a different mode
or fan speed.
Whenever the rear passengers have adjusted
settings on the rear climate control system,
the AUX light is lit on the front climate control
system. The driver can turn off the auxiliary fan
by pressing the AUX button.
When the front climate control system is turned
off or in defrost mode, the rear climate control
system is turned off. The rear system will turn
back on once another front mode is selected.
For more information on how to use the climate
control system, seeDual Climate Control System
on page 210. For more information on the air
outlets, seeOutlet Adjustment on page 217.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages on
your vehicle. The pictures help to locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to
cause an expensive repair or replacement. Paying
attention to the warning lights and gages could also
save you or others from injury.
Warning lights come on when there may be or is
a problem with one of your vehicle’s functions.
As the details show on the next few pages, some
warning lights come on briey when you start
the engine just to let you know they are working.
If you are familiar with this section, you should
not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions.
Often gages and warning lights work together
to let you know when there is a problem with
your vehicle.
When one of the warning lights comes on and
stays on as you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.
So please get to know your vehicle’s warning lights
and gages. They can be a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information Center
(DIC) on page 240for more information.

Safety Belt Reminder Light
When the key is turned to RUN or START, a chime
will sound for several seconds to remind you and
your passengers to buckle your safety belts. The
driver safety belt light will also come on and stay
on for several seconds, then it will ash for several
more. You should buckle your seat belt.
This chime and light
will be repeated if
the driver remains
unbuckled and
the vehicle is in
motion.
If the driver’s belt is buckled, neither the chime nor
the light will come on.
Passenger Safety Belt Reminder
Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds to
remind the front passenger to buckle their safety
belt. This would only occur if the passenger airbag
is enabled. SeePassenger Sensing System on
page 81for more information. The passenger
safety belt light will also come on and stay on for
several seconds, then it will ash for several more.
This chime and light
will be repeated if the
passenger remains
unbuckled and the
vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
