window CADILLAC STS V 2007 1.G Owner's Guide

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 264.
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 (three minutes if a new car
has 15 miles (24 km) or less). Power will be
restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy
lamp switch is turned on.
222

The URPA display is
located inside the
vehicle, above the
rear window. It has
three color-coded lights
that can be seen
through the rearview
mirror or by turning
around.
How the System Works
URPA comes on automatically when the shift lever
is moved into REVERSE (R) and the vehicle
speed is less than 3 mph (5 km/h). When
the system turns on, the three lights on the display
will illuminate for one and a half seconds to let
you know that the system is working. If your
vehicle is moving in REVERSE (R) at a speed
greater than 3 mph (5 km/h), the red light will ash
to remind you that the system does not work at
a speed greater than 3 mph (5 km/h).If an object is detected at a REVERSE (R) speed
of less than 3 mph (5 km/h), one of the following
will occur:
Description English Metric
Amber light 5 ft 1.5 m
Amber/amber lights 40 in 1.0 m
Amber/amber/red lights &
continuous chime20 in 0.5 m
Amber/amber/red lights
ashing & continuous
chime1 ft 0.3 m
A chime will sound the rst time an object is
detected between 20 inches (0.5 m) and
5 feet (1.5 m) away.
URPA cannot detect objects that are above trunk
level. In order for the rear sensors to recognize
an object, it must be within detection range behind
the vehicle.

Manual Operation
yNz(Mode):Pressing the mode switch and
changing the mode cancels automatic operation
and allows the operator to manually select the air
delivery location. Press AUTO to return to
automatic operation.
The outboard air outlets always receive airow
regardless of the mode selected. SeeOutlet
Adjustment on page 237to change this airow
from the outboard outlets.
To change the current mode, select one of the
following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode directs about half of the
air to the instrument panel outlets, and then
directs 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.
[(Floor):This mode directs most of the air to
the oor outlets with some air directed to the
outboard outlets, and a little air directed to
the windshield and side windows.The mode switch can also be used to select the
defog mode. Information on defogging and
defrosting can be found later in this section.
yAz(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch
cancels automatic operation and allows the
operator to manually select the amount of airow.
Press AUTO to return to automatic operation.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 239andScheduled Maintenance on
page 505.
h(Recirculation):Press this button to control
the air source for the climate control system. If
in AUTO mode, press this button once to
select recirculation. This mode keeps outside air
from coming in the vehicle and recirculates the air
in the vehicle. It can be used to prevent outside
air and odors from entering the vehicle or to
help cool the air inside the vehicle more quickly.
232

Recirculation is not available in the defrost mode
and shuts off when defog mode is selected.
Both of these features are designed to limit fogging
in the vehicle. If recirculation is selected during
defog mode, it automatically turns off after
10 minutes to limit problems with fogging.
In some conditions, using recirculation for long
periods of time can cause the air inside the vehicle
to become too dry or stuffy. To prevent this from
happening, after the air in the vehicle has
cooled, select AUTO to return to automatic climate
control operation or push the recirculation button
again to select outside air.
Press this button a second time to select
outside air.
:(Outside Air):This mode forces the system
to pull air from outside the vehicle. It can be
used to bring fresh air into the vehicle.
Air Quality Sensor:Your vehicle could have an
air quality sensor to help limit the climate
control system from pulling in some harmfulexhaust fumes from older, poorly running, or
diesel-equipped vehicles that are driving near you.
This sensor, when active, monitors the air
quality in front of your vehicle and switches to air
recirculation when poor quality air is detected
outside your vehicle. Press the AUTO button on
the climate control to activate the air quality
sensor. The word AUTO comes on the center of
the climate control display. While the air quality
sensor senses poor quality air, the recirculation
graphic displays.
Under some conditions, the air quality sensor
system does not operate. In cold weather, the
system might not be active (even if AUTO is
displayed) because of concerns of fogging your
windows, which may occur by activating
recirculation mode. Also, the air quality sensor
system does not remain in recirculation mode for
extended periods of time that could cause stuffy or
very dry conditions in the vehicle. Following a
poorly running vehicle for an extended period of
time may not keep recirculation active indenitely.
233

Sensors
There is a solar sensor located on the instrument
panel, near the windshield.
There is also an interior temperature sensor
located next to the steering wheel on the
instrument panel.
These sensors monitor the solar radiation and the
air inside the vehicle, then use the information
to adjust the temperature, the fan speed and the
air delivery system, in order to maintain theselected temperature. The system may also
supply cooler air to the side of the vehicle facing
the sun. Do not cover the sensors or the automatic
climate control system will not work properly.
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 the windshield. Use
the 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.
yNz(Mode):Press this button until defog
appears on the display.
-(Defog):This mode directs the air between
the windshield and oor outlets with some
air supplied to the outboard panel outlets and side
window defogging outlets. When this mode is
selected, the system turns off recirculation
and runs the air-conditioning compressor unless
the outside temperature is at or below freezing.
235

The recirculation mode is cancelled when the
system enters the defog mode. If recirculation is
selected while in the defog mode, it is cancelled
after 10 minutes.
If there is fogging on the side windows, remain in
defog or defrost mode until they clear.
0(Defrost):Press this button to direct most of
the air to the windshield, with some air directed
to the side windows and outboard panel outlets. In
this mode, the system automatically turns off
recirculation and runs the air-conditioning
compressor, unless the outside temperature is at
or below freezing. Recirculation cannot be
selected while in the defrost mode.
This mode can also cause the fan speed and air
temperature to increase.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger only works when the
ignition is on or during remote start, if
programmed. See “Personal Settings Menu” under
Vehicle Personalization on page 148for additional
information.
=(Rear Window Defogger):Press this button
to turn the rear window defogger on or off. Be
sure to clear as much snow from the rear window
as possible.
The rear window defogger turns off about
10 minutes after the button is pressed. If the
vehicle’s speed is above 30 mph (48 km/h), the
rear defogger stays on continuously. If turned
on again, the defogger only runs for about
ve minutes before turning off. The defogger can
also be turned off by pressing the button again
or by turning off the engine.
The heated outside rearview mirrors also heat to
help clear fog or frost from the surface of the
mirror when the rear window defogger is on. See
Outside Power Heated Mirrors on page 130.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.

BATTERY VOLTAGE HIGH
This symbol appears
with this message.
This message displays when the electrical
charging system is overcharging the battery.
When the system detects that the battery voltage
is above an estimated 16 volts, this message
displays.
To reduce the charging overload, use the vehicle’s
accessories. Turn on the exterior lamps and
radio, set the climate control on AUTO and the fan
speed on the highest setting, and turn the rear
window defogger on.
The normal battery voltage range is
11.5 to 15.5 volts when the engine is running.
You can monitor battery voltage on the DIC
by pressing the information button until you nd
BATTERY VOLTS.
BATTERY VOLTAGE LOW
This symbol appears
with this message.
This message displays when the electrical system
is charging less than 10 volts or the battery has
been drained.
If this message appears immediately after starting
the engine, it is possible that the generator can
still recharge the battery. The battery should
recharge while driving, but may take a few hours
to do so. Consider using an auxiliary charger
to boost the battery after returning home or to a
nal destination. Make sure you follow the
manufacturer’s instructions.
If this message appears while driving or after
starting your vehicle and stays on, have it checked
immediately to determine the cause of this problem.

Diversity Antenna System
The AM-FM antenna is integrated with the rear
window defogger, located in the rear window.
Make sure that the inside surface of the rear
window is not scratched and that the grid lines on
the glass are not damaged. If the inside surface
is damaged, it could interfere with radio reception.
Notice:Do not apply aftermarket glass tinting
with metallic lm. The metallic lm in some
tinting materials will interfere with or distort the
incoming radio reception. Any damage caused
to your antenna due to metallic tinting materials
will not be covered by your warranty.
Notice:Do not try to clear frost or other
material from the inside of the rear window
with a razor blade or anything else that
is sharp, as this may damage the rear window
defogger grid and affect your radio’s ability
to pick up stations clearly. The repairs would
not be covered by your warranty.If static is heard on the radio, when the rear
window defogger is turned on, it could mean that
a defogger grid line has been damaged. If this
is true, the grid line must be repaired.
If adding an aftermarket cellular telephone to your
vehicle, and the antenna needs to be attached
to the glass, make sure that the grid lines for the
AM-FM antennas are not damaged. Make sure
the cellular telephone antenna does not touch a
grid line.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
A vehicle with a sunroof might not get the
best performance from the XM™ system if the
sunroof is open.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.

Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the
lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
Maps:Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as highway
hypnosis? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch of road
with the same scenery, along with the hum of the
tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make
you sleepy. Do not let it happen to you! If it does,
your vehicle can leave the road in less than a
second, and you could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with
a comfortably cool interior.
Keep your eyes moving. Scan the road ahead
and to the sides. Check your rearview mirrors
and your instruments frequently.
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get
some exercise, or both. For safety, treat
drowsiness on the highway as an emergency.

You can run the engine to keep warm, but be
careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO
(carbon monoxide) gas to get inside. CO
could overcome you and kill you. You
cannot see it or smell it, so you might not
know it is in your vehicle. Clear away
snow from around the base of your
vehicle, especially any that is blocking the
exhaust pipe. And check around again
from time to time to be sure snow does
not collect there.
Open a window just a little on the side of
the vehicle that is away from the wind.
This will help keep CO out.
Run your engine only as long as you must. This
saves fuel. When you run the engine, make it go a
little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the
heat that you get and it keeps the battery charged.
