The HomeLink
®Universal Transceiver but-
ton has now been reprogrammed. The new
device can be activated by pushing the
HomeLink
®button that was just pro-
grammed. This procedure will not affect
any other programmed HomeLink
®buttons.
IF YOUR VEHICLE IS STOLEN
If your vehicle is stolen, you should change
the codes of any non-rolling code device that
has been programmed into HomeLink
®.
Consult the Owner’s Manual of each device
or call the manufacturer or retailer of those
devices for additional information.
When your vehicle is recovered, you will
need to reprogram the HomeLink
®Univer-
sal Transceiver with your new transmitter
information.

following two conditions: (1) This device
may not cause harmful interference, and (2)
this device must accept any interference
received, including interference that may
cause undesired operation. NOTE:
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user’s authority
to operate the equipment.
For Canada:
This device complies with Industry Canada
licence-exempt RSS standard(s). Operation
is subject to the following two conditions:
(1) this device may not cause interference,
and (2) this device must accept any inter-
ference, including interference that may

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 (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.
When the HomeLink
®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-
Instruments and controls2-75
HomeLink®UNIVERSAL
TRANSCEIVER (Type B) (if so equipped)

2-76Instruments and controls
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.
. Your vehicle’s engine should be
turned off while programming the
HomeLink
®Universal Transceiver.
Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death.
NOTE:
If your vehicle is equipped with Smart
Rearview Mirror, you may have to complete
additional programming to enable Two-
Way Communication. The mirror can pro- vide the status of your garage door (open/
close).
PROGRAMMING HomeLink®
The following steps show generic instruc-
tions how to program a HomeLink®button.
If you have any questions or are having
difficulty programming your HomeLink
®
buttons, refer to the HomeLink®web site
at: www.homelink.com/infiniti or call 1-
800-355-3515.
NOTE:
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-fre-
quency.

FUEL-FILLER CAP
WARNING
. Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or ser-
iously injured if it is misused or
mishandled. Always stop engine and
do not smoke or allow open flames or
sparks near the vehicle when refuel-
ing.
. Do not attempt to top off the fuel
tank after the fuel pump nozzle shuts
off automatically. Continued refuel-
ing may cause fuel overflow, resulting
in fuel spray and possibly a fire.
. Use only an original equipment type
fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious malfunction and possible injury. It
could also cause the malfunction
indicator light to come on.
. Never pour fuel into the throttle body
to attempt to start your vehicle.
. Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
— Always place the container on the ground when filling.
— Do not use electronic devices when filling.
— Keep the pump nozzle in contact with the container while you are
filling it.
— Use only approved portable fuel containers for flammable liquid.
CAUTION
. If fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage. .
Insert the cap straight into the fuel-
filler tube, then tighten until the fuel-
filler cap clicks. Failure to tighten the
fuel-filler cap properly may cause the
malfunction indicator light (MIL)
to illuminate. If thelight illumi-
nates because the fuel-filler cap is
loose or missing, tighten or install the
cap and continue to drive the vehicle.
The
light should turn off after a
few driving trips. If thelight does
not turn off after a few driving trips,
have the vehicle inspected. It is
recommended you visit an INFINITI
retailer for this service.
. The Loose Fuel Cap warning will
appear if the fuel-filler cap is not
properly tightened. It may take a few
driving trips for the message to be
displayed. Failure to tighten the fuel-
filler cap properly after the Loose
Fuel Cap warning appears may cause
the
Malfunction Indicator Light
(MIL) to illuminate.
Turn the cap counterclockwise to remove.
To tighten, turn the cap clockwise until a
single click is heard.

AROUND VIEW®MONITOR SYS-
TEM LIMITATIONS
WARNING
Listed below are the system limitations
for Around View®Monitor. Failure to
operate the vehicle in accordance with
these system limitations could result in
serious injury or death.
. Do not use the Around View
®Moni-
tor with the outside mirrors in the
stored position, and make sure that
the liftgate is securely closed when
operating the vehicle using the
Around View
®Monitor.
. The apparent distance between ob-
jects viewed on the Around View
®
Monitor differs from the actual dis-
tance.
. The cameras are installed on the
front grille, the outside mirrors and
above the rear license plate. Do not
put anything on the vehicle that
covers the cameras.
. When washing the vehicle with high
pressure water, be sure not to spray
it around the cameras. Otherwise,
water may enter the camera unit causing water condensation on the
lens, a malfunction, fire or an electric
shock.
. Do not strike the cameras. They are
precision instruments. Doing so could
cause a malfunction or cause damage
resulting in a fire or an electric shock.
