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 liftgate 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.

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 liftgate. Lock all doors. The doors can be locked with
the Intelligent Key, door handle request
switch, power door lock switch or me-
chanical key.
SECURITY SYSTEMS

5. Confirm that the security indicator lightcomes 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 liftgate 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 50 seconds. However, the
alarm reactivates if the vehicle is tam-
pered with again. The alarm is activated by:
.
Unlocking the door or opening the lift-
gate without using the button on the
Intelligent Key, the door handle request
switch 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 when a door is unlocked
by pushing the unlock button on the Intelli-
gent Key, the door handle request switch or
using the mechanical key, or when the
ignition switch is pushed to 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.

ROOF RACK
Do not apply any load directly to the roof
side rails. Cross bars must be installed before
applying load/cargo/luggage to the roof of
the vehicle. Genuine INFINITI accessory
cross bars are available through an INFINITI
retailer. It is recommended that you visit an
INFINITI retailer for additional information.
The service load capacity for the roof side
rails is 221 lb (100 kg), however do not
exceed the accessory cross bars load capa-
city.
Be careful that your vehicle does not exceed
the Gross Vehicle Weight Rating (GVWR) or
its Gross Axle Weight Rating (GAWR frontand rear). The GVWR and GAWR are
located on the F.M.V.S.S. or C.V.M.S.S.
certification label (located on the driver’s
door pillar). For additional information re-
garding GVWR and GAWR, refer to “Vehicle
loading information” (P.10-15).
WARNING
.
Always install the cross bars onto the
roof side rails before loading cargo of
any kind. Loading cargo directly onto
the roof side rails or the vehicle’s roof
may cause vehicle damage.
. Drive extra carefully when the vehicle
is loaded at or near the cargo carrying
capacity, especially if the significant
portion of that load is carried on the
roof rack.
. Heavy loading of the roof rack has
the potential to affect the vehicle
stability and handling during sudden
or unusual handling maneuvers.
. Roof rack load should be evenly
distributed.
. Do not exceed maximum roof rack
load weight capacity.
. Properly secure all cargo with ropes
or straps to help prevent it from
sliding or shifting. In a sudden stop or collision, unsecured cargo could
cause personal injury.

®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 (RF)
devices 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
vehicle’s battery is discharged or is
disconnected, HomeLink
®will retain all
programming.

®Universal Transceiver
is programmed, retain the original trans-
mitter for future programming procedures
(Example: new vehicle purchases). Upon
sale of the vehicle, the programmed
HomeLink
®Universal Transceiver buttons
should be erased for security purposes. For
additional information, refer to “Program-
ming HomeLink
®” (P.2-76).
WARNING
. Do not use the HomeLink®Universal
Transceiver with any garage door
opener that lacks safety stop and
reverse features as required by fed-
eral safety standards. (These stan- dards became effective for opener
models manufactured after April 1,
1982.) A garage door opener which
cannot detect an object in the path of
a closing garage door and then auto-
matically stop and reverse, does not
meet current federal safety stan-
dards. Using 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 pro-
gramming.
