2021 NISSAN SENTRA trunk

Your vehicle may have two types of security
systems:
• Vehicle security system (if so equipped)
• NISSAN 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 detec-
tion type system that activates when a ve-
hicle is moved or when a vibration occurs.The system helps detect vehicle thef t but
cannot prevent it, nor can it prevent the
thef t of interior or exterior vehicle compo-
nents in all situations. Always 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 protec-
tion, such as component locks, identifica-
tion markers, and tracking systems, are
available at auto supply stores and spe-
cialty shops. A NISSAN dealer may also offer
such equipment. Check with your insur-
ance company to see if you may be eligible
for discounts for various thef t protection
features.
How to arm the vehicle security
system
1. Close all windows and the moonroof.
The system can be armed even if the
windows and moonroof are open.
2. Remove the Intelligent Key from the vehicle. 3. Close all doors, hood and trunk. Lock all
doors. The doors can be locked with the
Intelligent Key, door handle request
switch (if so equipped), power door lock
switch or mechanical key (if so
equipped).
4. Wait 30 seconds for the system to com- plete the pre-armed phase.
If during the pre-armed phase one of
the following occurs, the system will not
arm:
• Any door is unlocked with the me- chanical key (if so equipped), Intelli-
gent Key or door request switch (if so
equipped).
• The ignition switch is placed in the AUTO ACC or ON position.
• Even when the driver and/or passen-
gers are in the vehicle, the system will
activate when all the doors, hood and
trunk are locked with the ignition
switch placed in the LOCK position.
When placing the ignition switch in the
ON position, the system will be re-
leased.

Vehicle security system activation
The vehicle security system will give the
following alarm:
• The headlights blink and the horn soundsintermittently.
• The alarm automatically turns off af ter a period of time. However, the alarm reacti-
vates if the vehicle is tampered with
again. The alarm can be shut off by un-
locking the driver's door or trunk lid with
the key, or by pressing the
button on
the Intelligent Key.
The alarm is activated by:
• opening the door or trunk lid without us- ing the key or Intelligent Key (even if the
door is unlocked by releasing the door
inside lock switch).
How to stop an activated alarm
The alarm stops only by unlocking a door
or the trunk with the mechanical key (if so
equipped), pressing the
button on the
Intelligent Key, or pushing the request
switch (if so equipped) on the driver's or
passenger's door with the Intelligent Key in
range of the door handle.
NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of a registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedures:
1. Leave the ignition switch in the ON posi- tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices.
Never leave these keys in the vehicle. FCC Notice:

Instruments and controls2-53

When the Rear Door Alert system is acti-
vated:
• When the driver puts the vehicle in the P(Park) position, a notification message
appears in the vehicle information dis-
play with the options to “Dismiss Mes-
sage” or “Disable Alert” if desired.– Select “Disable Alert” to temporarily disable for that stop.
– No selection or ‘Dismiss Message” will keep the alert enabled for that stop.
• If the alert is enabled when a driver exits the vehicle, a message will appear in the
vehicle information display that states
“Check Rear Seat for All Articles.”
If “Horn & Alert” setting is selected:
– – An audible horn sound will occur af ter
a short time unless a rear door is
opened and closed within a short time
to deactivate the alert.
–– If the doors are locked before the alert is deactivated by opening a rear door,
the horn will sound.
–– If the trunk is opened before a rear door is opened, the horn will be delayed until
af ter the trunk is closed.NOTE:
If “Alert Only ” setting is selected, the
message alert will still be shown in the
vehicle information display but the horn
will not sound.
WARNING
• If the driver selects “Disable Alert”, no
audible alert will be provided regard-
less of rear door open/close status.
• There may be times when there is an
object or passenger in the rear
seat(s) but the audible alert does not
sound. For example, this may occur if
rear seat passengers enter or exit the
vehicle during a trip.
• The system does not directly detect
objects or passengers in the rear
seat(s). Instead, it can detect when a
rear door is opened and closed, indi-
cating that there may be something
in the rear seat(s).
NOTE:
There may be times when the horn
sounds but there are no objects or pas-
sengers in the rear seat(s). For additional information, refer to “Rear
Door Alert is activated” in this section.
Instruments and controls2-65

The light illuminates when the trunk lid is
opened. When the trunk lid is closed, the
light goes off.
The light will go off af ter a period of time if
the trunk lid is lef t open, unless the ignition
switch is placed in the ON position.
For additional information, refer to “Exterior
and interior lights” in the “Do-it-yourself ”
section of this manual.The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-
held transmitters into one built-in device.
HomeLink® Universal Transceiver:
• Will operate most radio frequency de-
vices such as garage doors, gates, home
and office lighting, entry door locks and
security systems.
• Is powered by your vehicle's battery. No separate batteries are required. If the ve-
hicle's battery is discharged or is discon-
nected, HomeLink® will retain all pro-
gramming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming pro-
cedures (Example: new vehicle pur-
chases). Upon sale of the vehicle, the
programmed HomeLink® Universal
Transceiver buttons should be erased for
security purposes. For additional infor-
mation, refer to “Programming
HomeLink®” in this section.WARNING
• Your vehicle's engine should be
turned off while programming the
HomeLink® Universal Transceiver. Do
not breathe exhaust gases; they con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconscious-
ness or death.
• Do not use the HomeLink® Universal
Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982). A
garage door opener which cannot
detect an object in the path of a clos-
ing garage door and then automati-
cally stop and reverse, does not meet
current federal safety standards. Us-
ing a garage door opener without
these features increases the risk of
serious injury or death.
