CADILLAC DTS 2007 1.G Owners Manual

If the battery continues to discharge, even with
the engine idling at a higher rpm setting, some
electrical loads will automatically be reduced. When
this occurs, the rear window defogger may take
slightly longer to clear the glass, the heated seats
may not get as warm as they usually do and the
climate control fan may cut back to a lower speed.
For more battery saving information, see “Battery
Saver Active Message” underDIC Warnings and
Messages on page 246.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature
and state of charge. It then adjusts the voltage for
best performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC),
you may see the voltage move up or down.
This is normal. If there is a problem, an alert
will be displayed.The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to produce
all the power that is needed for very high electrical
loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans,
trailer loads, and loads plugged into accessory
power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It can
increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action
may be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver reduce
the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 246.

Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s
battery against drainage from the interior lamps,
trunk lamp, glove box lamp, or the garage door
opener. When the ignition is turned off, the power
to these features will automatically turn off after
10 minutes. Power will be restored for an additional
10 minutes if any door or trunk is opened, or the
courtesy lamp switch is turned on.
Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained, if the interior courtesy
lamps, reading/map lamps, visor vanity lamps
or trunk lamp are accidentally left on. If any
of these lamps are left on, they will automatically
turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until
one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then
on again.
The headlamps will time out after 10 minutes,
if they are manually turned on before the ignition
is off.
Ultrasonic Front and Rear Parking
Assist (UFRPA)
If your vehicle is equipped, the Ultrasonic Front and
Rear Parking Assist (UFRPA) system is designed
to help you park. It operates only at speeds less
than 5 mph (8km/h). UFRPA helps make parking
easier and helps you avoid colliding with objects
such as parked vehicles. The UFRPA system
detects objects that are close to the vehicle which
are at least 10 inches (25.4 cm) off the ground and
below hood or trunk level. The system detects
objects up to 4 feet (1.2 m) in front of the vehicle
and up to 8 feet (2.5 m) behind your vehicle.
UFRPA determines how close these objects are
from your bumpers within this area. Four ultrasonic
sensors on the front and rear bumpers are used to
detect the distance to the object.
202

{CAUTION:
The Ultrasonic Front and Rear Park Assist
(UFRPA) system does not replace driver
vision. UFRPA does not:
Operate above speeds of
5 mph (8 km/h).
Detect objects more than 4 feet
(1.2 meters) in front of the vehicle and
more than 8 feet (2.5 meters) behind
the vehicle. This distance may be less
during warmer or humid weather.
Detect objects that are below the
bumper, underneath the vehicle,
or that are very close to the vehicle.
Detect children, pedestrians, bicyclists,
or pets.
So if you do not use proper care before
moving forward or backing up, you could
hit a vehicle, child, pedestrian, bicyclist,
or pet, resulting in vehicle damage, injury,
or death. Even though the vehicle has the
CAUTION: (Continued)
CAUTION: (Continued)
UFRPA system, always check carefully
before moving forward or backing up by
checking in front of and behind your
vehicle.
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.
Front Parking Assist
DisplayRear Parking Assist
Display
203

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 240.
204

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.
206

A bicycle or an object is attached to the front
bumper 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
unless an object is detected when the vehicle is
shifted out of park. If this occurs, UFRPA will
return to normal operation when the vehicle is
driven forward above 15 mph (25 km/h).
The ultrasonic sensors are not kept clean.
So be sure to keep your vehicle’s front and rear
bumpers free of mud, dirt, snow, ice and slush.
For cleaning instructions, seeWashing Your
Vehicle on page 444. If after cleaning the front
and rear bumpers and driving forward at a
speed of at least 15 mph (25 km/h), the DIC
displays the PARKING ASSIST OFF message,
see your dealer/retailer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air
brakes on a very large truck or other
mechanical devices that interfere with
UFRPA performance.
When UFRPA is disabled without driver action
and the driver attempts to turn UFRPA back
on using the Driver Information Center (DIC),
the PARKING ASSIST ON option will not be
selectable if the necessary conditions stated
above for normal system operation are not met.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being
sure to check for other vehicles, obstructions
and blind spots.
For Driver Information Center messages related
to UFRPA, seeDIC Warnings and Messages
on page 246.
If the bumper is damaged, your UFRPA system
may not work properly. Take the vehicle to
your dealer/retailer to repair the system.
