Low tire pressure warning
If the vehicle is being driven with low tire
pressure, the warning light will illuminate. A
“Tire Pressure Low - Add Air” warning also
appears in the vehicle information display.
When the low tire pressure warning light il-
luminates, you should stop and adjust the
tire pressure of all four tires to the recom-
mended COLD tire pressure shown on the
Tire and Loading Information label located in
the driver's door opening. The low tire pres-
sure warning light does not automatically
turn off when the tire pressure is adjusted.
After the tire is inflated to the recommended
pressure, the vehicle must be driven at
speeds above 16 mph (25 km/h) to activate
the TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge to
check the tire pressure.
The “Tire Pressure Low - Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the low
tire pressure warning light remains
illuminated.
For additional information, see “Vehicle in-
formation display” (P. 2-19) and “Tire Pres-
sure Monitoring System (TPMS)” (P. 5-5) and
(P. 6-3).
TPMS malfunction
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is placed in the ON position. The light
will remain on after 1 minute. Have the sys-
tem checked. It is recommended that you visit
an INFINITI retailer for this service. The "Tire
Pressure Low — Add Air" warning does not
appear if the low tire pressure warning light
illuminates to indicate a TPMS malfunction.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” (P. 5-5) and “Tire
pressure” (P. 8-27).
WARNING
• Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
• If the light does not illuminate with the
ignition switch placed in the ON position,
have the vehicle checked as soon as pos-
sible. It is recommended that you visit an
INFINITI retailer for this service. •
If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location and
stop the vehicle as soon as possible. Driv-
ing with under-inflated tires may perma-
nently damage the tires and increase the
likelihood of tire failure. Serious vehicle
damage could occur and may lead to an
accident and could result in serious per-
sonal injury or death. Check the tire pres-
sure for all four tires. Adjust the tire
pressure to the recommended COLD tire
pressure show on the Tire and Loading
Information label located in the driver’s
door opening to turn the low tire pres-
sure warning light OFF. If the light still
illuminates while driving after adjusting
the tire pressure, a tire may be flat or the
TPMS may be malfunctioning. If you
have a flat tire, replace it with a replace-
ment tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service.

2-24Instruments and controls

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 devicessuch 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. 2-71).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. 5-14). 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.PROGRAMMING HOMELINK®
If you have any questions or are having diffi-
culty programming your HomeLink® but-
tons, refer to the HomeLink® web site at:
www.homelink.com or call

PROGRAMMING HOMELINK®
FOR CANADIAN CUSTOMERS
AND GATE OPENERS
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit) af-
ter several seconds of transmission – which
may not be long enough for HomeLink® to
pick up the signal during training. Similar to
this Canadian law, some U.S. gate operators
are designed to “timeout” in the same
manner.
If you live in Canada or you are having diffi-
culties training a gate operator orgarage
door opener by using the “Training” proce-
dures, replace “Programming HomeLink®”
step 2 with the following:
NOTE:
When programming a garage door opener,
etc., unplug the device during the “cycling”
process to prevent possible damage to the
garage door opener components.
1. For additional information, see “Program-
ming HomeLink®” step 1, (P. 2-71).
2.
Using both hands, simultaneously press and
hold the desired HomeLink® button and
the hand-held transmitter button. During
training, your hand-held transmitter may
automatically stop transmitting. Continue
to press and hold the desired HomeLink®
button while you press and re-press
(“cycle”) your hand-held transmitter every 2
seconds until the frequency signal has been
learned. The HomeLink® indicator light will
flash slowly and then rapidly after several
seconds upon successful training. DO NOT
release until the HomeLink® indicator light
flashes slowly and then rapidly. When the
indicator light flashes rapidly, both buttons
may be released. The rapid flashing indi-
cates successful training.
Proceed with “Programming HomeLink®”
step 3 to complete.
If the device was unplugged during the pro-
gramming procedure, remember to plug it
back in when programming is completed.
OPERATING THE HOMELINK®
UNIVERSAL TRANSCEIVER
The HomeLink® Universal Transceiver, after
it is programmed, can be used to activate the
programmed device. To operate, simply press
and release the appropriate programmed
HomeLink® Universal Transceiver button.
The amber indicator light will illuminate while
the signal is being transmitted.
For convenience, the hand-held transmitter
of the device may also be used at any time.
PROGRAMMING TROUBLE-
DIAGNOSIS
If the HomeLink® does not quickly learn the
hand-held transmitter information:
• replace the hand-held transmitter batteries with new batteries.
• position the hand-held transmitter with its battery area facing away from the
HomeLink® surface.
• press and hold both the HomeLink® and hand-held transmitter buttons without

•Make sure to engage the P (Park) posi-
tion and apply the parking brake when
parking your vehicle, riding on or off the
vehicle or loading luggage. Failure to do
so could cause the vehicle to move or roll
away unexpectedly and result in serious
personal injury or property damage.
The Intelligent Key system can operate all the
door locks using the remote control function
or pushing the request switch on the vehicle
without taking the key out from a pocket or
purse. The operating environment and/or
conditions may affect the Intelligent Key sys-
tem operation.
Be sure to read the following before using the
Intelligent Key system.
CAUTION
• Be sure to carry the Intelligent Key with
you when operating the vehicle.
• Never leave the Intelligent Key in the ve-
hicle when you leave the vehicle.
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 where
strong 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 appears in the
vehicle information display. For additional in-
formation, see “Vehicle information display
warnings and indicators” (P. 2-25).
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.
Pre-driving checks and adjustments3-7

•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.
OPERATING RANGE
The Intelligent Key functions can only be used
when the Intelligent Key is within the speci-
fied operating range from the door handle
request switch or the one touch unlock sen-
sor
O1. When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key operating range becomes narrower, and
the Intelligent Key may not function properly.
The operating range is within 31.5 in (80 cm)
from each request switch or one touch unlock
sensor
O1.
If the Intelligent Key is too close to the door
glass, handle or rear bumper, the request
switches or the one touch unlock sensor may
not function.
If any of the doors are recently closed and
locked, you must wait 2 seconds before you
can unlock the door with the one touch un-
lock sensor. Pulling the handle within 2 sec-
onds of locking the door will allow you time to
confirm that the door has been locked with-
out accidentally unlocking the door with the
one touch unlock sensor.
If you pull the door handle with your gloved
hand, the one touch unlock sensor operation
may not function.
When the Intelligent Key is within the operat-
ing range, it is possible for anyone, even
someone who does not carry the Intelligent
Key, to push the request switch or the one
touch unlock sensor to lock/unlock the door
within range.
