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 — 7 inch (18 cm) Type B”
(P. 2-34), and “Tire Pressure Monitoring Sys-
tem (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 af ter 1 minute. Have the
system checked. It is recommended that
you visit a NISSAN dealer 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 Pres-
sure Monitoring System (TPMS)” (P. 5-5) and
(P. 6-3).
WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
• If the light does not illuminate with
the ignition switch placed in the ON
position, have the vehicle checked as
soon as possible. It is recommended
that you visit a NISSAN dealer 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 loca-
tion and stop the vehicle as soon as
possible. Driving with under-inflated
tires may permanently damage the
tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an acci-
dent and could result in serious per-
sonal injury or death. Check the tire
pressure for all four tires. Adjust the
tire pressure to the recommended
COLD tire pressure show on the Tire
and Loading Information label lo-
cated in the driver’s door opening to turn the low tire pressure warning
light off. If the light still illuminates
while driving af ter 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 spare
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 a NISSAN
dealer for this service.
• When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for these services.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.

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 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 ve-
hicle's battery is discharged or is discon-
nected, HomeLink® will retain all
programming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming pro-
cedures (Example: new vehicle pur-
chases). Upon sale of the vehicle, the
programmed HomeLink® Universal
Transceiver buttons should be erased for
security purposes. For additional infor-
mation, see “Programming HomeLink®”
(P. 2-81).WARNING
• Your vehicle's engine should be
turned off while programming the
HomeLink® Universal Transceiver. For
additional information, see “Push-
button ignition switch” (P. 5-13). Do
not breathe exhaust gases; they con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconscious-
ness or death.
• Do not use the HomeLink® Universal
Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982.) A
garage door opener which cannot
detect an object in the path of a clos-
ing garage door and then automati-
cally stop and reverse does not meet
current federal safety standards. Us-
ing 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
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON posi-
tion (without starting the engine) when

1-800-355-3515.
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 “tim-
eout” 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 “Pro-
gramming HomeLink®” step 1, (P. 2-81). 2. Using both hands, simultaneously press
and hold the desired HomeLink® button
and the hand-held transmitter button.
During training, your hand-held trans-
mitter may automatically stop transmit-
ting. Continue to press and hold the de-
sired 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 af ter several
seconds upon successful training. DO
NOT release until the HomeLink® indica-
tor light flashes slowly and then rapidly.
When the indicator light flashes rapidly,
both buttons may be released. The rapid
flashing indicates successful training.
Proceed with “Programming
HomeLink®” step 3 to complete.
If the device was unplugged during the
programming procedure, remember to
plug it back in when programming is
completed.

• Be sure to carry the Intelligent Key
with you when operating the vehicle.
• Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key is always communicat-
ing with the vehicle as it receives radio
waves. The Intelligent Key transmits weak
radio waves. Environmental conditions
may interfere with the operation of the In-
telligent Key under the following operating
conditions:
• When operating near a location where strong radio waves are transmitted, such
as a TV tower, power station and broad-
casting station.
• When in possession of wireless equip- ment, such as a cellular telephone, trans-
ceiver 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

In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies de-
pending on the operating conditions, the
battery’s life is approximately two years. If
the battery is discharged, replace it with a
new one.
When the Intelligent Key battery is low, an
indicator illuminates in the vehicle informa-
tion display. For additional information, see
“Vehicle information display - 5 inch (13 cm)
Type A (if so equipped)” (P. 2-18) or “Vehicle
information display - 7 inch (18 cm) Type B (if
so equipped)” (P. 2-34).
Since the Intelligent Key is continuously re-
ceiving radio waves, if the key is lef t near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may be-
come shorter.
For additional information, see “Battery re-
placement” (P. 8-23).
As many as four Intelligent Keys can be
registered and used with one vehicle. For
