alarm NISSAN SENTRA 2021 Owners Manual

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

or the trunk with the mechanical key (if so

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:
