sensor CADILLAC SEVILLE 2001 5.G Owners Manual

1-29
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inflate (if battery power is available). You can lock
the doors again and turn the interior lamps off by using
the door lock and interior lamp controls.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger air bag.

Air bags are designed to inflate only once. After an
air bag inflates, you'll need some new parts for your
air bag system. If you don't get them, the air bag
system won't be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for your
vehicle covers the need to replace other parts.

Your vehicle is equipped with an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also equipped
with a crash sensing and diagnostic module, which
records information about the frontal air bag system. The module records information about the readiness
of the system, when the system commands air bag
inflation and driver's safety belt usage at
deployment. The module also records speed, engine
rpm, brake and throttle data.

Let only qualified technicians work on your air
bag systems. Improper service can mean that an
air bag system won't work properly. See your dealer
for service.
NOTICE:
If you damage the covering for the driver's
or the right front passenger's air bag, or the
air bag covering on the driver's and right front
passenger's seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right
front passenger's air bag, or both the air bag
module and seatback for the driver's and right
front passenger's side impact air bag. Do not
open or break the air bag coverings.

1-30 Automatic Occupant Sensor (AOS) System
Your vehicle may have an automatic system that will turn
off the right front passenger's frontal and side impact air
bags under certain conditions. The driver's frontal and
side impact air bags are not part of the AOS system.
United States CanadaIf the rearview mirror in your vehicle has PASSENGER
AIR BAG on it, your vehicle has the AOS system.
When you turn the key to ON or START, the words ON
and OFF will come on in the rearview mirror. See
ªPASSENGER AIR BAG ON/OFF Lightº in the Index.
If your rearview mirror doesn't have the words
PASSENGER AIR BAG on it, your vehicle doesn't
have the AOS system.
The AOS system works with sensors that are part of the
right front passenger's seat. The sensors are designed
to detect the presence of an occupant on the seat and
determine if the passenger's frontal and side impact
air bags should be on or off.

1-44 Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors, therefore, recommends that child
restraints be secured in the rear seat including an infant
riding in a rear
-facing infant seat, a child riding in a
forward
-facing child seat and an older child riding in a
booster seat. Unless your vehicle has the Automatic
Occupant Sensor (AOS) system, never put a rear
-facing
child restraint in the front passenger seat. Here's why:
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates. This is because the
back of the rear
-facing child restraint would be
very close to the inflating air bag. Unless your
vehicle has the Automatic Occupant Sensor
(AOS) system, always secure a rear
-facing child
restraint in a rear seat.
CAUTION: (Continued)
CAUTION: (Continued)
You may secure a forward-facing child restraint
in the right front seat, but before you do, always
move the front passenger seat as far back as it
will go. It's better to secure the child restraint
in a rear seat.
Wherever you install it, be sure to secure the child
restraint properly.
Keep in mind that an unsecured child restraint can move
around in a collision or sudden stop and injure people
in the vehicle. Be sure to properly secure any child
restraint in your vehicle
-- even when no child is in it.

1-49 Securing a Child Restraint in the Right
Front Seat Position
Your vehicle has a right front passenger air bag. Unless
your vehicle has the Automatic Occupant Sensor (AOS)
system, never put a rear
-facing child restraint in this
seat. Here's why:
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates. This is because the
back of the rear
-facing child restraint would be
very close to the inflating air bag. Always secure
a rear
-facing child restraint in the rear seat.
Although a rear seat is a safer place, you can secure a
forward
-facing child restraint in the right front seat.
You'll be using the lap
-shoulder belt. See the earlier
part about the top strap if the child restraint has one.
Be sure to follow the instructions that came with the
child restraint. Secure the child in the child restraint
when and as the instructions say.
1. Your vehicle has a right front passenger's air bag.
If your vehicle has the Automatic Occupant Sensor
(AOS) system and you're using a rear
-facing child
restraint in this seat, make sure the air bag is turned
off by looking at the status indicator in the rearview
mirror before you drive. See ªAutomatic Occupant
Sensor (AOS) Systemº in the Index for more on
this, including important safety information. If your
vehicle doesn't have the AOS system and you're
using a forward
-facing child restraint, always move
the seat as far back as it will go before securing it in
this seat. See ªSeatsº in the Index.
2. Put the restraint on the seat.

1-51
6. To tighten the belt, feed the lap belt back into the
retractor while you push down on the child restraint.
You may find it helpful to use your knee to push
down on the child restraint as you tighten the belt.7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If your vehicle has the Automatic Occupant Sensor
(AOS) system, before you begin to drive, check to
be sure the right front passenger's frontal and side
impact air bags are off if you're using a rear
-facing
infant restraint. If the air bags are off, the word OFF
will appear in the rearview mirror.
If the word ON appears in the rearview mirror, the
frontal and side impact air bags have not been turned
off. If this ever happens, unbuckle the safety belt and
perform the steps to install the rear
-facing restraint
again. If the air bags still don't turn off, install the
infant restraint in a rear seat position and have your
vehicle serviced as soon as possible.

2-29
OVERDRIVE (D): 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 doesn't seem to shift gears as you accelerate,
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 OVERDRIVE (D) for
higher speeds.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than OVERDRIVE (D).
Here are examples for using THIRD (3) instead
of OVERDRIVE (D):

When driving on hilly, winding roads.

When going down a steep hill.
SECOND (2): This position gives you more power. You
can use SECOND (2) on hills. It can help control your
speed as you go down steep mountain roads, but then
you would also want to use your brakes off and on.
NOTICE:
Don't shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h), or you can
damage your engine.

2-41
LO or HI: Move the lever up to LO for steady wiping
at a slow speed. Move the lever higher to HI for steady
wiping at a high speed.
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 frequent 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.Rainsense
II Wipers
The moisture sensor 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 INT
ADJ band away from you to the higher sensitivity
levels. 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.

2-42
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 Rainsense function. The Rainsense
system can be overridden at any time by manually
changing the wiper control to LO or HI speed.
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 fluid you need.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
To spray washer fluid 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 fluid to the windshield and the wiper will
either stop or return to your original wiping speed.
To spray washer fluid on the windshield in the demand
mode, press and hold the button until you have enough
fluid, and the wipers will either stop or return to your
original wiping speed.
CHECK WASHER FLUID will be displayed on the DIC
when the washer fluid reaches a low level.

2-50
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 ªdarkº and the lamps will come 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 lamps control knob to
turn the lamps back on. To delay the lamps from
turning off, see ªTwilight Sentinelº in the Index.

2-52
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the driver's door switches
and to the ignition key when a door is opened or if you
press the Remote Keyless Entry (RKE) transmitter
unlock button. The illuminated entry system works with
the light sensor and it must be dark outside in order for
the courtesy lamps or backlighting to turn on. The
courtesy lamps turn off approximately 25 seconds after
the last door is closed or after the ignition key is turned
to ON or if the RKE transmitter lock button is pressed.
The courtesy lamps turn off approximately 40 seconds
after the doors are unlocked with the RKE transmitter if
no door is opened.
Parade Dimming
This feature prohibits the dimming of the instrument
panel lights during daylight while the parking lamps are
on. This feature works with the light sensor and is fully
automatic. When the light sensor reads darkness outside,
the instrument panel lights can be adjusted by following
the steps under ªInstrument Panel Intensity/Brightness
Control.º Backlighting to the instrument panel will also
turn on.
Reading Lamps
The reading lamps are located in the roof. These lamps
and the interior courtesy lamps come on when any door
is opened and it is dark outside. The rear lamps come on
when a rear door is opened. Press the button near the
lamps to turn them 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, high blower fan, heated seats and engine
cooling fans.
