ECU INFINITI QX 2011 Service Manual

The system helps deter vehicle theft but cannot
prevent it, nor can it prevent the theft of interior
or exterior vehicle components 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 unat-
tended. Be aware of your surroundings, and
park in secure, well-lit areas whenever pos-
sible.
Many devices offering additional protection,
such as component locks, identification mark-
ers, and tracking systems, are available at auto
supply stores and specialty shops. Your INFINITI
retailer may also offer such equipment. Check
with your insurance company to see if you may
be eligible for discounts for various theft pro-
tection features.
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 posi-tion.
3. Remove the Intelligent Key from the ve- hicle.
4. Close all doors, hood and lift gate. 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 ve-
hicle security system is now pre-armed.
After about 30 seconds the vehicle secu-
rity system automatically shifts into the
armed phase. The security light begins to
flash once every approximately 3 sec-
onds. 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 lift gate locked with the igni-
tion 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 follow-
ing alarm:
● The headlights blink and the horn sounds
intermittently.
● The alarm automatically turns off after ap-
proximately 50 seconds. However, the alarm
reactivates if the vehicle is tampered with
again.
SIC2045
2-30Instruments and controls

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 Intelligent
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, have it checked by an INFINITI retailer.

and RSS-Gen of IC Rules. Operation is subject to
the following two conditions:
(1) this device may not cause interference, and
(2) this device must accept any interference, in-
cluding interference that may cause undesired

meter panel. It indicates the status of the
INFINITI Vehicle Immobilizer System.
The light blinks after the ignition switch was in
the ACC, OFF and LOCK position. This function
indicates the security systems equipped on the

WARNING
●Always make sure that the cargo is properly
secured. Use the suitable ropes and hooks.
● Unsecured cargo can become dangerous in
an accident or sudden stop.
● Never allow anyone to ride in the luggage
area. It is extremely dangerous to ride in a
cargo area inside of a vehicle. In a collision,
people riding in these areas are more likely
to be seriously injured or killed. ●
Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
● The child restraint top tether strap may be
damaged by contact with items in the cargo
area. Secure any items in the cargo area.
Your child could be seriously injured or killed
in a collision if the top tether strap is
damaged.
● Be sure everyone in your vehicle is in a seat
and using a seat belt properly.

ROOF RACK
Always distribute the luggage evenly on the roof
rack. Do not load more than 221 lb (100 kg) on
the roof rails. Observe the maximum load limit
shown on the crossbars or roof carriers when
you attach them on the roof rails. Contact an
INFINITI retailer for crossbar or other equipment
information.
Be careful that your vehicle does not exceed the
Gross Vehicle Weight Rating (GVWR) or its Gross
Axle Weight Rating (GAWR front and 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 more information re-
garding GVWR and GAWR, see “VEHICLE LOAD- ING INFORMATION” in the “9. Technical and
consumer information” section.
WARNING
●
Drive extra carefully when the vehicle is
loaded at or near the cargo carrying capac-
ity, especially if the significant portion of
that load is carried on the roof rack.
● Heavy loading of the roof rack has the poten-
tial to affect the vehicle stability and han-
dling 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 shift-
ing. In a sudden stop or collision, unsecured
cargo could cause personal injury.

Universal Transceiver provides 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) 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 vehi-
cle’s battery is discharged or is discon-
nected, HomeLink will retain all program-
ming.
Once HomeLink Universal Transceiver is pro-
grammed, retain the original transmitter for fu-
ture programming procedures (Example: new ve-
hicle purchases). Upon sale of the vehicle, the
programmed HomeLink Universal Transceiver
buttons should be erased for security purposes.

WARNING
●Do not use HomeLink Universal Transceiver
with any garage door opener that lacks
safety stop and reverse features as required
by federal 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
automatically stop and reverse, does not
meet current federal safety standards. Using
a garage door opener without these features
increases the risk of serious injury or death.
● During programming procedure, your garage
door or security gate may open or close.
Make sure that people and objects are clear
of the garage door, gate, etc. that you are
programming.
● Your vehicle’s engine should be turned off
while programming HomeLink Universal
Transceiver.
PROGRAMMING HOMELINK
To program your HomeLink Universal Trans-
ceiver to operate a garage door, gate, or entry
door opener, home or office lighting, you need
to be at the same location as the device. Note:
Garage door openers (manufactured after 1996)
have “rolling code protection”. To program a
garage door opener equipped with “rolling code
protection”; you will need to use a ladder to get
up to the garage door opener motor to be able
to access the “smart or learn” program button.
1. To begin, push and hold the 2 outer HomeLink buttons (to clear the memory)
until the indicator light
Ablinks (after 20
seconds). Release both buttons.
2. Position the end of the hand-held trans- mitter 1-3 inches away from the
HomeLink surface.
