WARNING
∙ Never allow anyone to ride in the cargo area or on the rear seat when it

these areas by passengers without
proper restraints could result in seri-
ous injury or death in an accident or
sudden stop. ∙ Properly secure all cargo with ropes or
straps to help prevent it from sliding
or shif ting. Do not place cargo higher
than the seatbacks. In a sudden stop
or collision, unsecured cargo could
cause personal injury.
∙ When returning the seatbacks to the upright position, be certain they are
completely secured in the latched po-
sition. If they are not completely se-
cured, passengers may be injured in
an accident or sudden stop.
∙ Closely supervise children when they are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
rear seatback and trunk lid securely
latched when not in use, and prevent
children’s access to car keys.

CAUTION
∙ Be sure to carry the Intelligent Keywith 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
broadcasting station.
∙ When in possession of wireless equip- ment, 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 control 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 park-
ing meter.
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, re-
fer to “Vehicle information display” in the
“Instruments and controls” section of this
manual.
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, refer to “Battery
replacement” in the “Do-it-yourself ” section
of this manual. As many as four Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, it is recom-
mended that you visit a NISSAN dealer.
CAUTION
Listed below are conditions or occur-
rences which will damage the Intelli-
gent 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 modif y the Intelli- gent 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
temperatures exceed 140°F (60°C).
3-8Pre-driving checks and adjustments

∙ Do not attach the Intelligent Key witha 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
Intelligent Key from the vehicle. This may
prevent the unauthorized use of the Intelli-
gent Key to operate the vehicle. For infor-
mation regarding the erasing procedure, it
is recommended that you visit 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 dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key system’s 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 oper-
ating range, it is possible for anyone, even
someone who does not carry the Intelli-
gent Key, to push the request switch to
lock/unlock the doors.

Lockout protection
To prevent the Intelligent Key from being
accidentally locked in the trunk, lockout
protection is equipped with the Intelligent

When all doors are locked and the trunk lid
is closed with the Intelligent Key inside the
trunk, the outside buzzer will sound and the
trunk will open.
HOW TO USE THE REMOTE
KEYLESS ENTRY FUNCTION
The remote keyless entry function can op-
erate all door locks using the remote key-
less function of the Intelligent Key. The re-
mote keyless function can operate at a
distance of 33 f t (10 m) away from the ve-
hicle. The operating distance depends
upon the conditions around the vehicle.
The remote keyless entry function may not
function under the following conditions:∙ When the Intelligent Key is not within the operational range.
∙ When the doors or the trunk are open or not closed securely.
∙ When the Intelligent Key battery is dis- charged.

3-14Pre-driving checks and adjustments

Intelligent Key button operation
light
The light blinks only when you push any
button on the Intelligent Key. The light illu-
mination only signifies that the key fob has
transmitted a signal. You may look and/or
listen to verif y that the vehicle has per-
formed the intended operation. The num-
ber of blinks identifies each registered key
(i.e. 1 blink = 1st key,...,4 blinks = 4th key) for
your own identification purposes.If the light does not blink, your battery may
be too weak to communicate to the ve-
hicle. If this occurs, the battery may need to
be replaced. For additional information re-
garding the replacement of a battery, refer
to “Battery replacement” in the “Do-it-
yourself ” section of this manual.
WARNING SIGNALS
To help prevent the vehicle from moving
unexpectedly by erroneous operation of
the Intelligent Key or to help prevent the
vehicle from being stolen, a chime or
buzzer sounds from inside and outside the
vehicle and a warning is displayed in the
instrument panel.
When a chime or beep sounds or a warning
is displayed, be sure to check the vehicle
and the Intelligent Key.
For additional information, refer to
“Troubleshooting guide” in this section and
“Vehicle information display” in the “Instru-
ments and controls” section of this manual.
TROUBLESHOOTING GUIDE
Verif y the location of all Intelligent Keys that
are programmed for the vehicle. If another
Intelligent Key is in range or inside the ve-
hicle, the vehicle system may respond dif-
ferently than expected.
