2022 INFINITI QX50 battery

For additional information, see “Exterior and
interior lights” (P. 8-24).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 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 vehi-
cle's battery is discharged or is discon-
nected, HomeLink® will retain all
programming.
When the HomeLink® Universal Transceiver
is programmed, retain the original transmit-
ter for future programming procedures (Ex-
ample: new vehicle purchases). Upon sale of
the vehicle, the programmed HomeLink®
Universal Transceiver buttons should be
erased for security purposes. For additional
information, see “Programming
HomeLink®” (P. 2-74).WARNING
• Your vehicle's engine should be turned
off while programming the HomeLink®
Universal Transceiver. For additional in-
formation, see “Push-button ignition
switch” (P. 5-13). Do not breathe ex-
haust gases; they contain colorless and
odorless carbon monoxide. Carbon mon-
oxide is dangerous. It can cause uncon-
sciousness or death.
• Do not use the HomeLink® Universal
Transceiver with any garage door opener
that lacks safety stop and reverse fea-
tures as required by federal safety stan-
dards. (These standards became effec-
tive 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 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 programming.

INFINITI INTELLIGENT KEY
Your vehicle can only be driven with the Intel-
ligent Keys which are registered to your vehi-
cle’s Intelligent Key System components and
INFINITI Vehicle Immobilizer System
components.Never leave the keys in the vehicle.
As many as four Intelligent Keys can be reg-
istered and used with one vehicle. The new
keys must be registered prior to use with the
Intelligent Key System and INFINITI Vehicle
Immobilizer System of your vehicle. It is rec-
ommended that you visit an INFINITI retailer
for this service. Since the registration process
requires erasing all memory in the Intelligent
Key components when registering new keys,
be sure to take all Intelligent Keys that you
have to an INFINITI retailer.A key number plate is supplied with your keys.
Record the key number and keep it in a safe
place (such as your wallet), not in the vehicle.
If you lose your keys, it is recommended that
you visit an INFINITI retailer for duplicates by
using the key number. INFINITI does not re-
cord key numbers so it is very important to
keep track of your key number plate.
A key number is only necessary when you
have lost all keys and do not have one to
duplicate from. If you still have a key, it can be
duplicated without knowing the key number.
CAUTION
Be sure to carry the Intelligent Key with
you when driving. The Intelligent Key is a
precision device with a built-in transmit-
ter. To avoid damaging it, please note the
following:
– The Intelligent Key is water resistant;
however, wetting may damage the In-
telligent Key. If the Intelligent Key gets
wet, immediately wipe until it is com-
pletely dry.
– Do not bend, drop or strike it against
another object.
– If the outside temperature is below 14°F
(-10°C), the battery of the Intelligent
Key may not function properly.LPD2848

3-2Pre-driving checks and adjustments

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 wherestrong radio waves are transmitted, such as
a TV tower, power station and broadcast-
ing station.
• When in possession of wireless equipment, such as a cellular telephone, transceiver or
a CB radio.
• When the Intelligent Key is in contact with or covered by metallic materials.
• When any type of radio wave remote con- trol 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 function
or use the mechanical key. Although the life of the battery varies de-
pending on the operating conditions, the bat-
tery’s life is approximately two years. If the
battery is discharged, replace it with a new
one.
When the Intelligent Key battery is low, a
“Key Battery Low” indicator illuminates in the
vehicle information display. For additional in-
formation, see “Vehicle information display
warnings and indicators” (P. 2-21).
Since the Intelligent Key is continuously re-
ceiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may become
shorter.
For additional information, see “Battery re-
placement” (P. 8-22).
CAUTION
Listed below are conditions or occurrences
which will damage the Intelligent Key:
• Do not allow the Intelligent Key, which
contains electrical components, to come
into contact with water or salt water.
This could affect the system function.
• Do not drop the Intelligent Key. •
Do not strike the Intelligent Key sharply
against another object.
• Do not change or modify the Intelligent
Key.
• Wetting may damage the Intelligent
Key. If the Intelligent Key gets wet, im-
mediately wipe until it is completely dry.
• Do not place the Intelligent Key for an
extended period in an area where tem-
peratures exceed 140°F (60°C).
• Do not attach the Intelligent Key with a
key holder that contains a magnet.
• Do not place the Intelligent Key near
equipment that produces a magnetic
field, such as a TV, audio equipment and
personal computers.
If an Intelligent Key is lost or stolen, INFINITI
recommends erasing the ID code of that In-
telligent Key from the vehicle. This may pre-
vent the unauthorized use of the Intelligent
Key to operate the vehicle. For information
regarding the erasing procedure, it is recom-
mended that you visit an INFINITI retailer.
