SIC2132
Your vehicle has two types of security
systems, as follows:
.Vehicle security system
. INFINITI Vehicle Immobilizer System
The security condition will be shown by the
security indicator light.
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual
and audio alarm signals if someone opens
the doors, hood, or trunk lid 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 compo-
nents in all situations. Always secure your
vehicle even if parking for a brief period.
Never leave your Intelligent Key(s) in the
vehicle, and always lock it 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 INFINITI retailer may also offer such
equipment. Check with your insurance com-
pany to see if you may be eligible for
discounts for various theft protection fea-
tures.
SECURITY SYSTEMS

SIC2045
How to arm the vehicle security
system
1. Close all windows.The system can be armed even if the
windows are open.
2. Push the ignition switch to the OFF position.
3. Remove the Intelligent Key from the vehicle.
4. Close all doors, hood and trunk. Lock all doors. The doors can be locked with the
Intelligent Key, door handle request
switch, power door lock switch or me-
chanical key. 5. Confirm that the security indicator light
comes on. The security indicator light
stays on for about 30 seconds. The
vehicle security system is now pre-
armed. After about 30 seconds the
vehicle security system automatically
shifts into the armed phase. The security
light begins to flash once every approxi-
mately 3 seconds. If, during this 30-
second pre-arm time period, the door is
unlocked, or the ignition switch is pushed
to ACC or ON, the system will not arm.
Even when the driver and/or passengers
are in the vehicle, the system will activate
with all doors, hood, and trunk lid locked
with the ignition switch in the LOCK
position. When pushing the ignition switch
to 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.
. The alarm automatically turns off after
approximately 1 minute. However, the
alarm reactivates if the vehicle is tam-
pered with again. The alarm is activated by:
.
Unlocking the door or opening the trunk
lid without using the button on the
Intelligent Key, the door handle request
switch, one touch unlock sensor or the
mechanical key. (Even if the door is
opened by releasing the door inside lock
knob, the alarm will activate.)
. Opening the hood.
How to stop an activated alarm
The alarm will stop by unlocking a door by
pushing the UNLOCK button on the Intelli-
gent Key, the door handle request switch,
touching the one touch unlock sensor or
using the mechanical key. The alarm will not
stop if the ignition switch is placed in the
ACC or ON position.
If the system does not operate as described
above, it is recommended you have it
checked by an INFINITI retailer.
INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered Intelligent Key.
Never leave these keys in the vehicle.
Instruments and controls2-31

for extended periods of time, other-
wise the battery will be discharged.
. Never leave the light switch on when
the engine is not running for a period
of time even if the headlights turn off
automatically.
Daytime running light system
The daytime running lights automatically
illuminate when the engine is started with
the parking brake released. The daytime
running lights operate with the headlight
switch in the OFF, AUTO or
position.
Turn the headlight switch to theposition
for full illumination when driving at night.
If the parking brake is applied before the
engine is started, the daytime running lights
do not illuminate. The daytime running lights
illuminate once the parking brake is released.
The daytime running lights will remain on
until the ignition switch is pushed to the OFF
position.
WARNING
When the daytime running light system
is active, tail lights on your vehicle are
not on. It is necessary at dusk to turn on
your headlights. Failure to do so could
cause an accident injuring yourself and others.
Adaptive Front lighting System
(AFS) (if so equipped)
The Adaptive Front lighting System (AFS)
will automatically adjust the headlights (low
beam) toward the turning direction to
improve the driver’s view. When the head-
light switch is ON and the driver operates
the steering wheel in a turn, the AFS system
will be activated.
The AFS will operate:
.
when the headlight switch is ON.
. when the shift lever is in any position
other than P (Park) or R (Reverse).
. when the vehicle is driven at above 3
MPH (5 km/h) for the left-side head-
light. Note that the right-side low beam
headlight will swivel but the left-side
headlight will not swivel when the vehicle
is below 3 MPH (5 km/h) and the
steering wheel is turned.
AFS will also adjust the headlight to a proper
axis automatically, depending on the number
of occupants in the vehicle, the load the
vehicle is carrying and the road conditions.
If the AFS warning appears in the vehicle
information display after the ignition switch
has been pushed to the ON position, this may indicate that the AFS is not functioning
properly. Have the system checked. It is
recommended you visit an INFINITI retailer
for this service. When the engine is started,
the headlights will vibrate to check the
system condition. This is not a malfunction.

conditions, the heater will not turn on even if
AUTO is selected. The settings for the AUTO
mode can be changed. For details, see the
INFINITI InTouch
TMOwner’s Manual.

WARNING
.Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use.
. The Intelligent Key transmits radio
waves when the buttons are pushed.
The FAA advises that the radio
waves may affect aircraft navigation
and communication systems. Do not
operate the Intelligent Key while on
an airplane. Make sure the buttons
are not operated unintentionally
when the unit is stored during a
flight.
The Intelligent Key system can operate all
the doors and the trunk lid using the remote
controller function, using one touch unlock
function or pushing the request switch on
the vehicle without taking the key out from a
pocket or purse. The operating environment
and/or conditions may affect the Intelligent
Key system operation.
Be sure to read the following before using
the Intelligent Key system.
CAUTION
. Be sure to carry the Intelligent Key
with you when operating the vehicle.
. Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key is always communicating
with the vehicle as it receives radio waves.
The Intelligent Key system transmits weak
radio waves. Environmental conditions may
interfere with the operation of the Intelligent
Key system under the following operating
conditions.
. When operating near a location where
strong radio waves are transmitted, such
as a TV tower, power station and broad-
casting station.
. When in possession of wireless equip-
ment, such as a cellular telephone,
transceiver, and CB radio.
. When the Intelligent Key is in contact
with or covered by metallic materials.
. When any type of radio wave remote
control is used nearby.
. When the Intelligent Key is placed near
an electric appliance such as a personal
computer. .
When the vehicle is parked near a parking
meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies
depending on the operating conditions, the
battery’s life is approximately 2 years. If the
battery is discharged, replace it with a new
one.
When the Intelligent Key battery is almost
discharged, see “Intelligent Key battery dis-
charge” (P.5-14) to start the engine.
Since the Intelligent Key is continuously
receiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and
personal computer, the battery life may
become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery replace-
ment” (P.8-26).
As many as 4 Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, contact an
INFINITI retailer.
