2004 CADILLAC SEVILLE sensor

Rainsense™ II Wipers
Your vehicle may be equipped with Rainsense™ II
wipers. The moisture sensor for this feature is mounted
on the interior side of the windshield below the
rearview mirror and is used to automatically operate the
wipers by monitoring the amount of moisture build-up
on the windshield. Wipes occur as needed to clear
the windshield depending on driving conditions and the
sensitivity setting. In light rain or snow, fewer wipes
will occur. In heavy rain or snow, wipes will occur more
frequently. The Rainsense™ wipers operate in a
delay mode as well as a continuous low or high speed
as needed. If the system is left on for long periods
of time, occasional wipes may occur without any
moisture on the windshield. This is normal and indicates
that the Rainsense™ system is activated.
The Rainsense™ system can be activated by moving
the wiper stalk up to the INT position and turning the INT
ADJ band to one of the five sensitivity levels. The
bottom INT ADJ position is the lowest sensitivity setting,
level one. This allows more rain or snow to collect on
the windshield between wipes. Turning the INT ADJ
band away from you to the higher sensitivity levels
allows less rain or snow to collect on the windshield
between wipes.The top position is the highest sensitivity setting, level
five. A single wipe will occur each time you turn the INT
ADJ band to a higher sensitivity level to indicate that
the sensitivity level has been increased.
Notice:Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.
The MIST and “wash” cycles operate as normal and are
not affected by the Rainsense™ function. The
Rainsense™ system can be overridden at any time by
manually changing the wiper control to LO or HI speed.
While Rainsense™ is active, the headlamps will turn on
automatically. The headlamps will turn off again once
the wipers turn off if it is light enough outside. If it
is dark, they will remain on. See “Wiper-Activated
Headlamps” underExterior Lamps on page 3-16for
more information.
Notice:Do not place stickers or other items on the
exterior glass surface directly in front of the
moisture sensor. Doing this could cause the
moisture sensor to malfunction.

Light Sensor
The light sensor for the Daytime Running Lamps (DRL)
and the Twilight Sentinel®is located on the driver’s
side of the front defogger grille.
If you cover the sensor, it will read “dark” and the
exterior lamps or the HEADLAMPS SUGGESTED
message will be on whenever the ignition is on.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off approximately ten
minutes after the ignition is turned to OFF. This
protects against draining the battery in case you have
accidentally left the headlamps or parking lamps on. The
battery saver does not work if the headlamps are
turned on after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on. To delay the lamps from turning off, see
Twilight Sentinel
®listed previously in this section.
3-21

Entry Lighting
The entry lighting system automatically turns on the
courtesy lamps and the backlighting to the door switches
and to the exterior lamp control when a door is opened
or if you press the remote keyless entry transmitter
unlock button. If activated due to the transmitter,
the lighting will remain active for about 40 seconds.
Since the entry lighting system uses the light sensor, it
must be dark outside in order for the courtesy lamps
to turn on. The courtesy lamps turn off approximately
25 seconds after the last door is closed. They will dim to
off if the ignition key is placed in ON, or immediately
deactivate if the power locks are activated.
Parade Dimming
This feature prohibits dimming of the digital displays and
backlighting during daylight hours when the key is in
the ignition and the headlamps are on. This feature
operates with the light sensor for the Twilight
Sentinel
®and is fully automatic. When the light sensor
reads darkness outside and the parking lamps are
active, the digital displays can be adjusted by turning
the instrument panel brightness knob counterclockwise
to dim and clockwise to brighten lighting.
Reading Lamps
The front reading lamps are located in the overhead
console. These lamps and the interior courtesy lamps
come on when a door is opened and it is dark outside.
The rear reading lamps will not come on when a
front door is opened.
The rear courtesy lamps are located on the rear
headliner above the rear seat outboard positions. When
a rear door is opened, both the front and rear reading
lamps come on with the courtesy lamps.
Press the button near each lamp to turn it on and 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.

CAUTION: (Continued)
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using Rear Park Assist,
always check carefully behind your vehicle
before you back up and then watch closely as
you do.
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). When the system comes on,
the three lights on the display will briefly illuminate 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 flash to remind you the
system does not work at this speed.
The first time an object is detected while in
REVERSE (R), a chime will sound and the following will
occur in sequence, depending on the distance from
the object:
•At 5 feet (1.5 m) a chime will sound and one amber
light will be lit;
•at 40 inches (1.0 m) both amber lights will be lit;
•at 20 inches (0.5 m) a continuous chime will sound
and all three lights (amber/amber/red) will be lit; and
•at 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will flash.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the
rear sensors to recognize an object, it must be within
operating range.
3-25

If the URPA system is not functioning properly, the
display will flash red, indicating that there is a problem.
The light will also flash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or hanging out of your trunk. The light will
continue to flash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h).
It may also flash red if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper free of
mud, dirt, snow, ice and slush or materials such as
paint or the system may not work properly. If after
cleaning the rear bumper and driving forward at least
15 mph (25 km/h), the display continues to flash red, see
your dealer. For cleaning instructions, seeCleaning
the Outside of Your Vehicle on page 5-90.
It may also flash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h).
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.
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.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.
The accessory power outlets are located at the rear of
the center console and on the lower inboard carpeted
panel on the passenger’s side of the vehicle.
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.
The accessory power outlet will only operate when the
ignition is in ACC or ON and for 10 minutes after
turning the ignition OFF. If you would like the accessory
power outlet to operate regardless of ignition position,
and for extended periods of time, see your dealer
for more information.
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 plugs.

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.
When your vehicle is first started, the display will show
the driver’s temperature setting, the fan speed and
the air delivery mode.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
will show readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between them.
Manual Operation
SMODET: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.
To change the current mode, select one of the following:
G(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 floor 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 floor outlets.
8(Floor):This mode directs most of the air to the
floor outlets with some air directed to the outboard
outlets (for the side windows) a little air directed to the
windshield.
The MODE switch can also be used to select the
floor/defog mode. Information on defogging and
defrosting can be found later in this section.
y9z(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 airflow seems low when the fan speed is at
the highest setting, the passenger compartment air filter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-35
andScheduled Maintenance on page 6-4.
3-29

SensorsThe solar sensor on your vehicle monitors the solar
radiation inside your vehicle, then uses 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 solar sensor located in
the middle of the instrument panel, near the windshield
or the system will not work properly.
There is also an outside temperature sensor located
under the front bumper and an inside temperature
sensor located to the left of the ignition switch. These
sensors read the outside and inside air temperature and
help to maintain the selected temperature inside the
vehicle. If you cover these sensors, it could cause
a false reading in the temperature.
3-31

Engine Speed Limiter
This feature prevents the engine from operating at too
many revolutions per minute (rpm). When the engine’s
rpm are critically high, the fuel supply to the engine
is shut off. When the engine speed slows, the fuel
supply will come on again. This helps prevent damage
to the engine.
Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for several seconds to remind people to fasten
their safety belts.
The safety belt light will
also come on and stay on
for several seconds. If
the driver’s belt is already
buckled, the light will
come on briefly, but the
chime will not sound.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG or the air bag symbol. The
system checks the air bag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the air bag
sensors, the air bag modules, the wiring and the crash
sensing and diagnostic module. For more information
on the air bag system, seeSupplemental Inatable
Restraint (SIR) on page 1-41.
This light will come on when you start your vehicle, and
it will flash for a few seconds. Then the light should
go out. This means the system is ready.
