2007 CADILLAC STS Owners Manual

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.
The vehicle does not have any cigarette lighters
for the rear seat passengers.
To activate the cigarette lighter, push it into the
heating element and let go. When the lighter
is ready it will pop back out by itself.
Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, and ventilation for the vehicle.
Automatic Operation

AUTO (Automatic):When this button is pressed
and the temperature is set, the system will
automatically control the inside temperature, the
air delivery mode, the air conditioning compressor,
and the fan speed. AUTO will appear on the
display next to the fan, mode indicators,
and recirculation indicator if your vehicle has a air
quality sensor.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable
setting, generally, between 70°F (21°C)
and 80°F (27°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or
cool any faster. If the system is set at
the warmest temperature setting, the system
will try to continuously heat the vehicle
and will not adjust the system down as the
vehicle warms up.In cold weather, the system can start at
reduced fan speeds to avoid blowing cold air
into the vehicle until warmer air is available.
The system starts out blowing air at the oor,
but can automatically change modes as
the vehicle warms up to maintain the chosen
temperature setting. The length of time
needed for warm up depends on the outside
temperature and the length of time that
has elapsed since the vehicle was last driven.
3. Wait for the system to regulate. This may take
from 10 to 30 minutes. Then adjust the
temperature, if necessary.
You can switch from English to metric units
through the Driver Information Center (DIC). See
DIC Controls and Displays on page 258.
The air-conditioning system removes moisture
from the air, so some water might drip underneath
the vehicle while idling or after turning off the
engine. This is normal.
231

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.
