tion.NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer system will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using a registered key
(for example, when interference is caused by
another registered key, an automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedure:
1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake and clutch fluid(if so equipped) ,
and windshield-washer fluid as frequently as
possible, or at least whenever you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Lock all doors.
● Position seat and adjust head
restraints/headrests.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is placed in the ON posi-
tion. See “Warning/indicator lights and au-
dible reminders” in the “Instruments and
controls” section of this manual.

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 lever to N (Neu-
tral) . For CVT models, move the shift
lever 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.
●
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.
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.
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.
