CADILLAC STS 2007 1.G Owners Manual

Reading Lamps
The reading lamps are located on the overhead
console. These lamps come on automatically when
any door is opened.
For manual operation, press the button next to
each lamp to turn it on or off.
If the reading lamps are left on, they automatically
shut off 10 minutes after the ignition has been
turned off.
Battery Load Management
The battery load management feature is designed
to monitor the vehicle’s electrical load and
determine when the battery is in a heavy discharge
condition. During times of high electrical loading,
the engine may idle at a higher
revolutions per minute (rpm) setting than normal to
make sure the battery charges. High electrical
loads may occur when several of the following are
on: headlamps, high beams, fog lamps, rear
window defogger, the climate control fan at high
speeds, heated seats and engine cooling fans.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 and the
fan may cut back to a lower speed. For more
battery saving information, see “Battery Saver
Active Message” underDIC Warnings and
Messages on page 264.
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.
221

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

Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high
in your eld of view, it may take you more
time to see things you need to see when it
is dark outside. Be sure to keep the HUD
image dim and placed low in your eld
of view.
If equipped, the Head-Up Display (HUD) allows
you to see some of the driver information that
appears on your instrument panel cluster on the
windshield.
The information may be displayed in English or
metric units and appears as an image focused out
toward the front of your vehicle. To change
from English to metric units, seeDIC Controls and
Displays on page 258.
The HUD consists of the following information:
Speedometer
Turn Signal Indicators
High-Beam Indicator Symbol
Driver Shift Control Transmission Feature,
seeAutomatic Transmission Operation on
page 116
Check Gages Icon
Adaptive Cruise Control Features and
Indicators (If Equipped), seeAdaptive Cruise
Control on page 197
Forward Collision Alert Features and
Indicators (If Equipped), seeForward Collision
Alert (FCA) System on page 184
Radio Features
United States version shown, Canada similar
223

Be sure to continue scanning your displays,
controls and driving environment just as you would
in a vehicle without HUD. If you never look at your
instrument panel cluster, you may not see
something important, such as a warning light.
Under important warning conditions, the CHECK
GAGES message will display in the HUD. View
your Driver Information Center (DIC) for more
information.
The HUD controls are
located to the left of the
steering wheel on the
DIC control panel.
~(Head-Up Display):Press this button to
change the position of the HUD on the windshield.
Press the top part of the button to move the
HUD image up. Press the bottom part of the button
to move the HUD image down.You can also adjust the brightness of the HUD
image. Press the knob on the center of the
DIC control panel in until it pops out and then pull
the knob until is completely extended. Turn the
knob clockwise or counter-clockwise to increase or
decrease the brightness. If you turn the knob all
the way to the left, the HUD image will turn off.
To adjust the HUD so you can see it properly,
do the following:
1. Adjust the seat to a comfortable driving
position. If you change your seat position later,
you may have to re-adjust your HUD.
2. Start your engine and press the top or bottom
of the HUD button to center the HUD image in
your view.
The HUD image can only be adjusted up and
down, not side-to-side.
3. Turn the knob on the DIC control panel to
adjust the brightness of the HUD image.
The brightness of the HUD image is determined
by the light conditions in the direction your vehicle
is facing and where you have the HUD set.
If you are facing a dark object or a heavily shaded
area, your HUD may anticipate that you are
entering a dark area and may begin to dim.
224

To turn the HUD image off, turn the knob
counter-clockwise.
Polarized sunglasses could make the HUD image
harder to see.
As light shines out from the HUD, it is possible for
light to shine back in. In rare occurrences,
when the sun is at a specic angle and position,
the sun’s rays can shine back into the HUD. When
this occurs, the display device within the HUD
will be temporarily illuminated. The event will end
when the vehicle’s angle to the sun changes.
Clean the inside of the windshield as needed to
remove any dirt or lm that reduces the sharpness
or clarity of the HUD image.
To clean the HUD, spray household glass cleaner
on a soft, clean cloth. Wipe the HUD lens gently,
then dry it.
Notice:When cleaning, be careful not to
scratch the HUD or camera lenses. Do
not spray glass cleaner directly on the HUD
lens because the cleaner could leak inside the
unit and cause damage.
If the ignition is on and you cannot see the HUD
image, check to see if:
Something is covering the HUD unit.
The brightness is adjusted properly.
The HUD image is adjusted to the
proper height.
Ambient light in the direction your vehicle is
facing is low.
A fuse is blown. SeeFuses and Circuit
Breakers on page 487.
Keep in mind that your windshield is part of the
HUD system. SeeWindshield Replacement
on page 419.
The following Adaptive Cruise Control message
may appear in the HUD:
PEDAL APPLIED ACC OVERRIDE:This
message indicates that you are pressing your
foot on the accelerator pedal and overriding
Adaptive Cruise Control. While you are doing
this, the system will not automatically apply the
brakes. 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.
You may also see an Adaptive Cruise Control
active symbol, alert symbol or vehicle ahead
symbol. SeeAdaptive Cruise Control on page 197
for more information.

Ultrasonic Rear Parking
Assist (URPA)
The Ultrasonic Rear Parking Assist (URPA)
system is designed to help you park while the
vehicle is in REVERSE (R). It operates only at very
low speeds, less than 3 mph (5 km/h). URPA
can help make parking easier and help you avoid
colliding with objects such as parked vehicles.
The URPA system can detect objects up to
5 feet (1.5 m) behind the vehicle, and tell you how
close these objects are from your rear bumper.
{CAUTION:
The Ultrasonic Rear Park Assist (URPA)
system does not replace driver vision.
URPA does not:
Operate above speeds of 3 mph (5 km/h).
Detect objects more than 5 feet
(1.5 meters) behind the vehicle.
This distance may be less during
warmer or humid weather.
CAUTION: (Continued)
CAUTION: (Continued)

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
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 URPA system,
always check carefully before backing up
by checking behind your vehicle.
226

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.
227

When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R), if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper
free of mud, dirt, snow, ice and slush. Other
conditions that may affect system performance
include things like the vibrations from a jackhammer
or the compression of air brakes on a very large
truck. If after cleaning the rear bumper and then
driving forward at least 15 mph (25 km/h), the
display continues to ash red, see your dealer.
If a trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your trunk
during your last drive cycle, the light may also
ash red. The light will continue to ash whenever
in REVERSE (R) until your vehicle is driven
forward at least 15 mph (25 km/h) without any
obstructions behind the vehicle.
For cleaning instructions, seeWashing Your
Vehicle on page 480.
Accessory Power Outlet(s)
Your vehicle is equipped with accessory power
outlets. The outlets can be used to plug in
electrical equipment such as a cellular telephone,
CB radio, etc.
Your vehicle has one outlet in front of the center
console, one in the center console lid and
there may be an additional outlet in the rear of the
center console.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet. If it
does, when not using the outlet be sure to cover
it with the protective cap.
Notice:Leaving electrical equipment plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.
228

Certain accessory power plugs may not be
compatible to the accessory power outlet and
could result in blown vehicle or adapter fuses. If
you experience a problem, see your dealer
for additional information on the accessory
power outlets.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your
warranty. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer before adding electrical
equipment.
Follow the proper installation instructions that are
included with any electrical equipment you install.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.Ashtray(s) and Cigarette Lighter
Your vehicle may have an ashtray and
cigarette lighter.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle. Never
put ammable items in the ashtray.
Ashtray
The ashtray is located under the climate control
panel on the center console. Press on the door to
release the ashtray. The ashtray will automatically
slide open for use.
To empty the ashtray with the ashtray in full open
position, locate the release button to the right
of the ash receiver and slide it to the right (in the
direction of the arrow). The ash receiver will
unlock and lift slightly and can then be easily
removed from the housing. To replace the
ash receiver, place it into position in the ashtray
housing and push down rmly until it locks
into place.
229

Cigarette Lighter
Notice:Holding a cigarette lighter in while it
is heating will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in
while it is heating. Do not use equipment
exceeding maximum amperage rating of
15 amperes.
The cigarette lighter is located next to the ashtray.
