WARNING
Do not use or allow occupants to use the
climate controlled seats if you or the occu-
pants cannot monitor seat temperatures
or have an inability to feel pain in those
body parts in contact with the seat. Use of
the climate controlled seats by such people
could result in serious injury.
CAUTION
• The battery could run down if the climate
control seat is operated while the engine
is not running.
• Do not use the climate control seat for
extended periods or when no one is using
the seat.
• Do not put anything on the seat which
insulates heat, such as a blanket, cush-
ion, seat cover, etc. Otherwise, the seat
may become overheated.
• Do not place anything hard or heavy on
the seat or pierce it with a pin or similar
objects. This may result in damage to the
climate controlled seat.
• Any liquid spilled on the seat should be
removed immediately with a dry cloth.
• When cleaning the seat, never use gaso-
line, benzine, thinner, or any similar
materials.
• If any malfunctions are found or the cli-
mate controlled seat does not operate,
turn the switch off and have the system
checked. It is recommended that you
visit an INFINITI retailer for this service. The climate controlled seat cools down the
front seat by blowing cool air from under the
surface of the seat. The climate control
switch is located on the center console.
The climate controlled seat can be operated
as follows:
1. Place the ignition switch in the ON
position.
2. Push the climate controlled seat switches to cool the seat. The indicator light on the
corresponding switch will illuminate.
3. Adjust the desired amount of air by push- ing the switch again. The climate con-
trolled seat blower remains on low speed
for approximately 60 seconds after push-
ing the switch on.
4. When the vehicle's interior is warmed or cooled, or before you leave the vehicle, be
sure to turn off the climate controlled
seats. To turn off the climate controlled
seats, push the switch until the indicator
light does not illuminate.

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 dis-
connected, HomeLink® will retain all
programming.
When the HomeLink® Universal Transceiver is
programmed, retain the original transmitter
for future programming procedures (Example:
new vehicle purchases). Upon sale of the ve-
hicle, the programmed HomeLink® Universal
Transceiver buttons should be erased for se-
curity purposes. For additional information,
see “Programming HomeLink®” (P. 2-80).
WARNING
• 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.
• 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 dangerous. It can cause un-
consciousness or death.PROGRAMMING HOMELINK®
The following steps show generic instruc-
tions on 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 trans-
mission of the radio-frequency.
