ECU NISSAN MAXIMA 2021 Owner´s Manual

The system helps deter 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 Intelligent Key in the ve-
hicle, and always lock the vehicle when un-
attended. 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.(The system can be
armed even if the windows 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 or door handle request
switch.
4. Confirm that the
security indicator
light stays on for about 30 seconds. The
vehicle security system is now pre-
armed. The vehicle security system will
automatically shif t into the armed
phase. The
security light begins to
flash once every three seconds. If during
the pre-armed phase one of the follow-
ing occurs, the system will not arm:
• Any door is unlocked with the Intelligent Key or door request switch.
• Ignition switch is placed in ACC or ON position.
• Even when the driver and/or passen-
gers are in the vehicle, the system will
activate with all the doors, hood and
trunk lid locked with the ignition switch
placed in the LOCK position. When plac-
ing the ignition switch in the ACC or ON
position, the system will be released.
Vehicle security system activation
The vehicle security system will give the
following alarm:
• The headlights blink and the horn sounds intermittently but synchronously.
• 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 is activated by:
• opening any door or hood without using the Intelligent Key (even if the door is un-
locked by releasing the door inside lock
knob).
How to stop an activated alarm
The alarm stops only by pushing thebutton on the Intelligent Key, or pushing the
request switch on the driver's or passen-
ger'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 reoccurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. Never leave these keys in the vehicle.

PERSONAL LIGHTS
To turn the rear personal lights on, push the
switch. To turn them off, push the switch
again.The light illuminates when the trunk lid is
opened. When the trunk lid is closed, the
light goes off. For additional information,
see “Exterior and interior lights” (P. 8-24).
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
programming.
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, see “Programming HomeLink®”
(P. 2-74).

WARNING
• Your vehicle's engine should be
turned off while programming the
HomeLink® Universal Transceiver. For
additional information, see “Push-
button ignition switch” (P. 5-10). 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. •
During the programming procedure
your garage door or security gate will
open and close (if the transmitter is
within range). Make sure that people
or objects are clear of the garage
door, gate, etc., that you are
programming.
PROGRAMMING HOMELINK®
If you have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON or ACC
position (without starting the engine)
when programming HomeLink®. It is also
recommended that a new battery be
placed in the hand-held transmitter of
the device being programmed to
HomeLink® for quicker programming
and accurate transmission of the radio
frequency. 1. Position the end of your hand-held
transmitter 1–3 in (2–8 cm) away from
the HomeLink® surface, keeping the
HomeLink® indicator light
O1in view.

through unintended operation of the
vehicle and/or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-

locked, and then the Intelligent Key is put
inside the vehicle and all the doors are
closed, a warning chime will sound and the
doors will automatically unlock.
NOTE:
The doors may not lock when the Intelli-
gent Key is in the same hand that is op-
erating the request switch to lock the
door. Put the Intelligent Key in a purse,
pocket or your other hand.
CAUTION
The lockout protection may not func-
tion under the following conditions:
• When the Intelligent Key is placed on
top of the instrument panel.
• When the Intelligent Key is placed in-
side the glove box or a storage bin.
• When the Intelligent Key is placed in-

haust gas (carbon monoxide)”
(P. 5-4).
• Closely supervise children when they
are around cars to prevent them
from playing and becoming locked in
the trunk where they could be seri-
