2003 CADILLAC SEVILLE sensor

REVERSE (R):Use this gear to backup.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage your transaxle.
Shift to REVERSE (R) only after your vehicle is
stopped.
Also use this gear to rock your vehicle back and forth to
get out of snow, ice or sand without damaging your
transaxle. See
If You Are Stuck: In Sand, Mud, Ice or
Snow on page 4-30for additional information.
NEUTRAL (N):In this position, the engine doesn't
connect with the wheels. To restart when you're already
moving, use NEUTRAL (N) only. Also use NEUTRAL (N)
when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is ®rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.AUTOMATIC OVERDRIVE (
X):This position is for
normal driving. If you need more power for passing,
and you're:
·Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
·Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transaxle will shift down to the next gear and
have more power.
Notice:If your vehicle seems to start up rather
slowly, or if it seems not to shift gears as you go
faster, something may be wrong with a transaxle
system sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens,
have your vehicle serviced right away. Until then,
you can use SECOND (2) when you are driving
less than 35 mph (55 km/h) and AUTOMATIC
OVERDRIVE (D) for higher speeds.

INT (Delay):Move the lever up to the INT position,
then turn the INT ADJ band, which is located on
the lever, to adjust the delay time. The higher you turn
the INT ADJ band, the more frequently the wipers
will operate.
OFF:Lower the lever to its resting position (OFF) to
turn off the wipers.
MIST:Pull the lever down once and release it for a
single wipe cycle. For more cycles, hold the lever down
in the MIST position longer.
To wash the windshield, press the button located at the
tip of the lever.
Be sure to clear ice and snow from the wiper blades
before using them. If they're frozen to the windshield,
carefully loosen or thaw them. If the blades do become
damaged, get new blades or blade inserts.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload.
Your vehicle is equipped with wiper-activated
headlamps. After the windshield wipers have been on
for approximately six seconds, the headlamps will
automatically turn on. See
Wiper Activated HeadlampsunderExterior Lamps on page 3-16for more
information.
RainsenseŸ II Wipers
Your vehicle may be equipped with RainsenseŸ 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 RainsenseŸ 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 RainsenseŸ system is activated.
The RainsenseŸ system can be activated by moving
the wiper stalk up to the INT position and turning the INT
ADJ band to one of the ®ve 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.
3-11

The top position is the highest sensitivity setting, level
®ve. 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:The wipers must be turned off when going
through a car wash to avoid damage.
The MIST and ªwashº cycles operate as normal and are
not affected by the RainsenseŸ function. The
RainsenseŸ system can be overridden at any time by
manually changing the wiper control to LO or HI speed.
While RainsenseŸ 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 ªWiper-Activated
Headlampsº under
Exterior 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.
Windshield Washer
The windshield washer has both a ªdemandº mode and
a ªprogrammedº mode, depending on the amount of
windshield washer ¯uid you need.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer ¯uid can form ice on the windshield,
blocking your vision.
To spray washer ¯uid on the windshield in the
programmed mode, press and release the button on the
tip of the lever. The washer will provide a measured
amount of ¯uid to the windshield and the wiper will either
stop or return to your original wiping speed. To spray
washer ¯uid on the windshield in the demand mode,
press and hold the button until you have enough ¯uid,
and the wipers will either stop or return to your
original wiping speed.
CHECK WASHER FLUID will be displayed on the Driver
Information Center (DIC) when the washer ¯uid
reaches a low level.

Light Sensor
The light sensor for the Daytime Running Lamps (DRL)
and the Twilight Sentinelžis located on the driver's
side of the front defogger grille.
If you cover the sensor, it will read ªdarkº 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 Sentinelžlisted previously in this section.
3-20

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
žand 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.

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 comes on,
the three lights on the display will illuminate to let you
know that the system is working. URPA senses
how close your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located on the
rear bumper. When you shift into REVERSE (R) and
an object is detected, 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 ¯ash.
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.If the URPA system is not functioning properly, the
display will ¯ash red, indicating that there is a problem.
The light will also ¯ash 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 ¯ash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h).
It may also ¯ash 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 ¯ash red, see
your dealer. For cleaning instructions, see
Cleaning
the Outside of Your Vehicle on page 5-86.
It may also ¯ash 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.

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 and
the fan speed. AUTO will appear on the display.1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70ÉF (21ÉC) and 80ÉF (27ÉC).
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.
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 ªSensorsº later in
this section.
3-28

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.
