2004 CADILLAC SRX Owners Manual

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 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 liftgate level.
In order for the rear sensors to recognize an object,
it must be within detection range behind the vehicle.
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 on the back of, or hanging out of your
liftgate 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, seeCleaning the Outside of
Your Vehicle on page 5-97.

Accessory Power Outlets
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 rear of the center console, one in
the rear compartment, 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 on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.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. 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.

Ashtrays and Cigarette Lighter
Your vehicle may have an ashtray and cigarette lighter.
Notice:If you put papers 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.
To empty the ashtray, remove it from the center
console by gripping the edges and pulling straight out.
To reinstall, push the tray back into place.
There may also be ashtrays in the rear doors.
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.
The cigarette lighter is located next to the ashtray.
The vehicle does not have any cigarette lighters for the
rear seat passengers.
Press the lighter all the way in and release it. It will pop
back out by itself once the element has heated for use.
Cigarette lighters can be used to provide power to
accessories. SeeAccessory Power Outlets on
page 3-24for more information.

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your 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.1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
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 you set the system at the warmest
temperature setting, the system will remain in
manual mode at that temperature and it will not go
into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting.
The length of time needed for warm up will depend
on the outside temperature and the length of
time that has elapsed since your 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). If you have the Base
audio system, seeDIC Main Menu on page 3-60.Ifyou
have the Navigation system, see “Setup Menu” in the
Index of the Entertainment and Navigation System
Supplement.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.
Manual Operation
yNz(Mode):Pressing the MODE switch and
changing the mode cancels automatic operation
and places the system in manual mode. Press AUTO to
return to automatic operation.
The outboard air outlets will always receive airow
regardless of the mode selected. SeeOutlet Adjustment
on page 3-31to 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 approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets.
Some air may be directed toward the windshield.
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 (for the side windows), and a little air directed to
the windshield.
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 places the system in manual
mode. 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, see
Passenger Compartment Air Filter on page 3-34
andScheduled Maintenance on page 6-4.
h(Recirculation):This mode keeps outside air
from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or
to help heat or cool the air inside your vehicle more
quickly. Press this button to turn the recirculation mode
on or off. The air-conditioning compressor also
comes on.
Recirculation is not available in the defrost mode and
will automatically turn off after 10 minutes when
defog is selected.Using recirculation for long periods of time may cause
the air inside your vehicle to become too dry or
stuffy. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
QPWRR(Power/Driver’s Temperature):Press
the PWR button located on the driver’s side of the
climate control panel to turn the entire climate control
system on or off. Press the up or down arrow on

Sensors
There is a solar sensor located on the instrument panel,
near the windshield.There is also an interior
temperature sensor
located to the right of the
steering wheel on the
instrument panel.
These sensors monitor the solar radiation and the
air inside your vehicle, then use the information to
maintain the selected temperature by initiating needed
adjustments to the temperature, the fan speed and the air
delivery system. The system may also supply cooler air to
the side of the vehicle facing the sun. The recirculation
mode will also be activated, as necessary. Do not cover
the sensors or the automatic climate control system will
not work properly.
3-29

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 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, oor outlets and side windows. 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 is cancelled when you enter
defog mode. If you select recirculation while in defog
mode, it will be cancelled after 10 minutes.If you have fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. SeeOutlet Adjustment on page 3-31
for more information.
0(Defrost):Pressing defrost directs most of the air
to the windshield, with some air directed to the side
windows. 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.
This mode may also cause the fan speed and air
temperature to increase.
If you have fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. SeeOutlet Adjustment on page 3-31
for more information. Do not drive the vehicle until all the
windows are clear.
