WARNING
●Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use.
● The Intelligent Key transmits radio
waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraft navigation and communi-
cation systems. Do not operate the In-
telligent Key while on an airplane. Make
sure the buttons are not operated unin-
tentionally when the unit is stored for a
flight.
The Intelligent Key can operate all the door locks
using the remote controller function or pushing
the request switch on the vehicle without taking
the key out from a pocket or purse. The operating
environment and/or conditions may affect the
Intelligent Key operation.
Be sure to read the following before using the
Intelligent Key:
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 system 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 almost dis-
charged, insert the Intelligent Key into the Intelli-
gent Key port to start the Hybrid System. Replace
the discharged battery with a new one as soon as
possible. For more details, see “Push-button ig-
nition switch” in the “Starting and driving” sec-
tion.
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.

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
●This vehicle has high voltage DC and AC
systems as well as a 12-volt system. DC
and AC high voltage is very dangerous
and can cause severe burns and electric
shock that may result in serious injury
or death.
● Never touch, disassemble, remove or
replace the high voltage parts, cables
and their connectors. High voltage
cables are orange. Touching, disassem-
bling, removing or replacing those parts
and cables can cause severe burns or
electric shock that may result in serious
injury or death. ●
Never try to remove the service discon-
nect located in the trunk on the lower
right-hand side. The service disconnect
is used only when the vehicle is ser-
viced by trained technicians wearing
personal protection equipment and is
part of the high voltage system. Touch-
ing the service disconnect can cause
severe burns or electric shock that may
result in serious injury or death.
● The hybrid system uses high voltage up
to 650 V. The system can be hot while
and after starting. Be careful of both the
high voltage and the high temperature.
Obey the caution labels attached to the
vehicle.
● Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. 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. ●
The engine can start at any time without
warning when the Hybrid System is in
the READY mode. If you must work with
the Hybrid System in the READY mode,
keep your hands, clothing, hair and
tools away from fans, belts and any
other parts that can move.
● 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.

BATTERY REPLACEMENT
Maintenance and do-it-yourself8-23

Replace the battery in the Intelligent Key as fol-
lows:1. Remove the mechanical key from the Intelli- gent Key.
2. Insert a small screwdriver
Ainto the slitB
of the corner and twist it to separate the
upper part from the lower part. Use a cloth to
protect the casing.
3. Replace the battery with a new one. Recommended battery: CR2032 or equiva-
lent.
●Do not touch the internal circuit and elec-
tric terminals as doing so could cause a
malfunction.
● Hold the battery by the edges. Holding
the battery across the contact points will
seriously deplete the storage capacity.
● Make sure that the + side faces the bot-
tom of the case. 4. Close the lid securely as illustrated
CD.
5. Operate the buttons to check the operation.
See a NISSAN dealer if you need assistance for
replacement.
