2007 NISSAN SENTRA ecu

cOccupied passenger seat and the passen-
ger meet the conditions outlined in this sec-
tion: The light
oris OFF to in-
dicate that the front passenger air bag is
operational.
Front passenger air bag
The front passenger air bag is designed to auto-
matically turn OFF when the vehicle is operated
under some conditions as described below in
accordance with U.S. regulations. If the front
passenger air bag is OFF, it will not inflate in a
crash. The driver air bag and other air bags in your
vehicle are not part of this system.
The purpose of the regulation is to help reduce
the risk of injury or death from an inflating air bag
to certain front passenger seat occupants, such
as children, by requiring the air bag to be auto-
matically turned OFF. Certain sensors are used
to meet the requirements.
One sensor used is the occupant classification
sensor (pressure sensor) . It is in the bottom of the
front passenger seat cushion and is designed to
detect an occupant and objects on the seat by
weight. It works together with seat belt sensors
described later. For example, if a child is in the
front passenger seat, the advanced air bag sys-
tem is designed to turn the passenger air bag
OFF in accordance with the regulations. Also, if a
child restraint of the type specified in the regula-tions is on the seat, its weight and the child’s
weight can be detected and cause the air bag to
turn OFF. Occupant classification sensor opera-
tion can vary depending on the front passenger
seat belt sensors.
The front passenger seat belt sensors are de-
signed to detect if the seat belt is buckled and the
amount of tension on the seat belt, such as when
it is in the automatic locking mode (child restraint
mode) . Based on the weight on the seat detected
by the occupant classification sensor and the belt
tension detected on the seat belt, the advanced
air bag system determines whether the front pas-
senger air bag should be automatically turned
OFF as required by the regulations.
Front passenger seat adult occupants who are
properly seated and using the seat belt as out-
lined in this manual should not cause the passen-
ger air bag to be automatically turned OFF. For
small adults it may be turned OFF, however if the
occupant takes his/her weight off the seat cush-
ion (for example, by not sitting upright, by sitting
on an edge of the seat, or by otherwise being out
of position) , this could cause the sensor to turn
the air bag OFF. In addition, if the occupant
improperly uses the seat belt in the automatic
locking mode (child restraint mode) , this could
cause the air bag to be turned OFF. Always be
sure to be seated and wearing the seat beltproperly for the most effective protection by the
seat belt and supplemental air bag.
NISSAN recommends that pre-teens and chil-
dren be properly restrained in a rear seat.
NISSAN also recommends that appropriate child
restraints and booster seats be properly installed
in a rear seat. If this is not possible, the occupant
classification sensor and seat belt sensors are
designed to operate as described above to turn
the front passenger air bag OFF for specified
child restraints as required by the regulations.
Failing to properly secure child restraints and to
use the automatic locking mode (child restraint
mode) may allow the restraint to tip or move in an
accident or sudden stop. This can also result in
the passenger air bag inflating in a crash instead
of being OFF. See “Child restraints” earlier in this
section for proper use and installation.
If the front passenger seat is not occupied the
passenger air bag is designed not to inflate in a
crash. However, heavy objects placed on the
seat could result in air bag inflation, because of
the object’s weight detected by the occupant
classification sensor. Other conditions could also
result in air bag inflation, such as if a child is
standing on the seat, or if two children are on the
seat, contrary to the instructions in this manual.
Always be sure that you and all vehicle occupants
are seated and restrained properly.

Your vehicle may have two types of security sys-
tems:
cVehicle security system (if so equipped)
cNISSAN Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM (if so
equipped)
The vehicle security system provides visual and
audible alarm signals if someone opens the doors
when the system is armed. It is not, however, a
motion detection type system that activates when
a vehicle is moved or when a vibration occurs.The system helps deter vehicle theft but cannot
prevent it, nor can it prevent the theft of interior or
exterior vehicle components in all situations. Al-
ways secure your vehicle even if parking for a
brief period. Never leave your keys in the ignition,
and always lock the vehicle when unattended. Be
aware of your surroundings, and park in secure,
well-lit areas whenever possible.
Many devices offering additional protection, such
as component locks, identification markers, and
tracking systems, are available at auto supply
stores and specialty shops. Your NISSAN dealer
may also offer such equipment. Check with your
insurance company to see if you may be eligible
for discounts for various theft protection features.
How to arm the vehicle security
system
1. Close all windows.(The system can be
armed even if the windows are open.)
2. Turn the ignition switch to the LOCK posi-
tion and remove the key.
3. Close all doors. Lock all doors. The doors
can be locked with:
cthe power door lock switch (if the door is
opened, locked and then closed) .
cthe key — master or mechanical (Intelli-
gent Key models) .

tion later in this manual.
4. Confirm that the
indicator light comes
on. Thelight stays on for about 30
seconds. The vehicle security system is now
pre-armed. After about 30 seconds the ve-
hicle security system automatically shifts
into the armed phase. The
light begins
to flash once every 3 seconds. If, during the
30-second pre-arm time period, the driver’s
door is unlocked by the key, a request
switch, the keyfob or Intelligent Key, or if the
ignition switch is turned to ACC or ON, the
system will not arm.cIf the key is turned slowly when locking
the driver’s door, the system may not
arm. Furthermore, if the key is turned
beyond the vertical position toward the
unlock position to remove the key, the
system may be disarmed when the key
is removed. If the indicator light fails to
glow for 30 seconds, unlock the door
once and lock it again.
cEven when the driver and/or passen-
gers are in the vehicle, the system will
arm with all doors closed and locked
with the ignition key in the OFF posi-
tion.
Vehicle security system activation
The vehicle security system will give the following
alarm:
cThe headlights blink and the horn sounds
intermittently.
cThe alarm automatically turns off after ap-
proximately 50 seconds. However, the alarm
reactivates if the vehicle is tampered with
again. The alarm can be shut off by unlocking
the driver’s door with the key, a request
switch or by pressing the
button on
the keyfob or Intelligent Key.The alarm is activated by:
copening a door without using the key, a
request switch, keyfob or Intelligent Key
(even if the door is unlocked by using the
inside lock knob or the power door lock
switch) .
How to stop an activated alarm
The alarm stops only by unlocking the driver’s
door with the key, pressing thebutton on
the keyfob or Intelligent Key, or by unlocking all
doors with any request switch (Intelligent Key
models) .
NISSAN VEHICLE IMMOBILIZER
