●When a spare tire is mounted or a wheel
is replaced tire pressure will not be in-
dicated, the TPMS will not function and
the low tire pressure warning light will
flash for approximately 1 minute. The
light will remain on after 1 minute. Con-
tact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
●Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
CAUTION
●The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
●If the vehicle is being driven at speeds
of less than 16 MPH (25 km/h) , the
TPMS may not operate correctly.
●Be sure to install the specified size of
tires to the 4 wheels correctly.

CAUTION
●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 communicating with
the vehicle as it receives radio waves. The Intel-
ligent Key transmits weak radio waves. Environ-
mental conditions may interfere with the opera-
tion of the Intelligent 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 broadcasting
station.
●When in possession of wireless equipment,
such as a cellular telephone, transceiver,
and CB radio.
●When the Intelligent Key is in contact with or
covered by metallic materials.
●When any type of radio wave remote control
is used nearby.
●When the Intelligent Key is placed near an
electric appliance such as a personal com-
puter.●When the vehicle is parked near a parking
meter.
In such cases, correct the operating conditions
before using the Intelligent Key function or use
the mechanical key.
Although the life of the battery varies depending
on the operating conditions, the battery’s life is
approximately 2 years. If the battery is dis-
charged, replace it with a new one.
When the Intelligent Key battery is low, the Intel-
ligent Key system warning light (
) will blink
green for about 30 seconds after the ignition
switch is placed in the ON position.
Since the Intelligent Key is continuously receiving
radio waves, if the key is left near equipment
which transmits strong radio waves, such as sig-
nals from a TV and personal computer, the bat-
tery life may become shorter.
For information regarding replacement of a bat-
tery, see “Battery replacement” in the “Mainte-
nance and do-it-yourself” section.
As many as 4 Intelligent Keys can be registered
and used with one vehicle. For information about
the purchase and use of additional Intelligent
Keys, contact a NISSAN dealer.
CAUTION
●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, NISSAN
recommends erasing the ID code of that Intelli-
gent Key from the vehicle. This may prevent the
unauthorized use of the Intelligent Key to operate
the vehicle. For information regarding the erasing
procedure, contact a NISSAN dealer.
OPERATING RANGE
The Intelligent Key functions can only be used
when the Intelligent Key is within the specified
operating range from the request switch
1.
When the Intelligent Key battery is discharged or
strong radio waves are present near the operat-
ing location, the Intelligent Key operating range
becomes narrower, and the Intelligent Key may
not function properly.
The operating range is within 31.50 in (80 cm)
from each request switch
1.If the Intelligent Key is too close to the door glass,
handle or rear bumper, the request switches may
not function.
When the Intelligent Key is within the operating
range, it is possible for anyone, even someone
who does not carry the Intelligent Key, to push the
request switch to lock/unlock the doors.

When installing a CB, ham radio or car phone in
your NISSAN, be sure to observe the following
precautions; otherwise, the new equipment may
adversely affect the engine control system and
other electronic parts.
WARNING
●A cellular telephone should not be used
while driving so full attention may be
given to vehicle operation. Some juris-
dictions prohibit the use of cellular tele-
phones while driving.
●If you must make a call while your ve-
hicle is in motion, the hands free cellu-
lar phone operational mode (if so
equipped) is highly recommended. Ex-
ercise extreme caution at all times so
full attention may be given to vehicle
operation.
●If you are unable to devote full attention
to vehicle operation while talking on
the phone, pull off the road to a safe
location and stop your vehicle.
CAUTION
●Keep the antenna as far away as pos-
sible from the electronic control
modules.
●Keep the antenna wire more than 8 in
(20 cm) away from the electronic con-
trol system harnesses. Do not route the
antenna wire next to any harness.
●Adjust the antenna standing-wave ratio
as recommended by the manufacturer.
●Connect the ground wire from the CB
radio chassis to the body.
●For details, consult a NISSAN dealer.
WARNING
●Use a phone after stopping your vehicle
in a safe location. If you have to use a
phone while driving, exercise extreme
caution at all times so full attention may
be given to vehicle operation.
●If you are unable to devote full attention
to vehicle operation while talking on
the phone, pull off the road to a safe
location and stop your vehicle.
CAUTION
To avoid discharging the vehicle battery,
use a phone after starting the engine.
