engine INFINITI QX80 2019 Service Manual

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.2-73).
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.
. 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.
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.

Pre-driving checks and adjustments3-17

WARNING
To avoid risk of injury or death, do not
use the remote engine start function
when the vehicle is in an enclosed area
such as a garage.
JVP0445X
The remote engine startbutton is on the
Intelligent Key if the vehicle has remote
engine start function. This function allows
the engine to start from outside the vehicle.
Some systems, such as the air conditioner
system, will turn on during a remote engine
start, if the system was on the last time the
ignition switch was turned off.
Laws in some local communities may restrict
the use of remote engine starters. For
example, some laws require a person using
remote engine start to have the vehicle in
view. Check local regulations for any re-
quirements.
Other conditions may affect the remote
engine start function. See “Conditions the remote engine start will not work” (P.3-20).
Other conditions can affect the performance
of the Intelligent Key transmitter. See “In-
telligent Key system” (P.3-7) for additional
information.
REMOTE ENGINE START OPER-
ATING RANGE
The remote engine start function can only be
used when the Intelligent Key is within the
specified operating range from the vehicle.
When the Intelligent Key battery is dis-
charged or other strong radio wave sources
are present near the operating location, the
Intelligent Key operating range becomes
narrower, and the Intelligent Key may not
function properly.
The remote engine start operating range is
approximately 197 ft (60 m) from the
vehicle.
REMOTE STARTING THE ENGINE
To use the remote engine start function to
start the engine, perform the following:
1. Aim the Intelligent Key at the vehicle.
2. Push the “LOCK”
button to lock all
doors.
3. Within 5 seconds push and hold the remote engine start
button until

19). Run time will be calculated as follows:
. The first 10 minute run time will start
when the remote engine start function is
performed.
. The second 10 minutes will start imme-
diately when the remote engine start function is performed. For example, if
the engine has been running for 5
minutes, and 10 minutes are added, the
engine will run for a total of 15 minutes.
. Extending engine run time will count
towards the two remote engine start
limit.
A maximum of two remote engine starts, or
a single start with an extension, are allowed
between ignition cycles.
The ignition switch must be cycled to the ON
position and then back to the OFF position

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.
