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.

(
) blinks red and the outside buzzer
sounds, make sure the Intelligent Key is inside the
vehicle.
Warning for low battery power
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. This warning
is to let you know that the battery of the Intelligent
Key will run down soon. Replace it with a new
one. Refer to “Battery replacement” in the “Main-
tenance and do-it-yourself” section.
NISSAN recommends replacing the battery at a
NISSAN dealer.
Preventing the Intelligent Key from
being left in the vehicle
If you lock all doors using the power door lock
switch with the Intelligent Key in the vehicle, all of
the doors unlock immediately and the buzzer will
warn you when the door is closed.

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
●Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. For manual transmission
models, move the shift selector to N
(Neutral) . For CVT models, move the
shift selector to P (Park) .
●Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
●If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
●It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
●Always wear eye protection whenever
you work on your vehicle.●If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
●Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
●Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
●On gasoline engine models, the fuel
filter or fuel lines should be serviced by
a NISSAN dealer because the fuel lines
are under high pressure even when the
engine is off.
CAUTION
●Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
●Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.●Never leave the engine or the CVT re-
lated component harness connector
disconnected while the ignition switch
is in the ON position.
●Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
●Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition key is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A genuine NISSAN service manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “Technical and consumer
information” section of this manual.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage.If in doubt about any servicing,
have it done by a NISSAN dealer.
