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. 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. ●
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition switch is in the OFF posi-
tion and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before working
near the fan.
● 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 automatic
transmission related component har-
nesses 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.
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.

KEYFOB (if so equipped)
Replace the battery in the keyfob as follows:
1Open the lid using a coinA.
2Remove the batteryB.
3Install a new batteryCwith the “+” facing
down.
● Hold the battery by the edges. Holding the
battery across the contact points will seri-
ously deplete the storage capacity. ●
Do not touch the internal circuit and electric
terminals as it could cause a malfunction.
● When changing the battery, do not let dust
or oil get on the keyfob.
● There is danger of explosion if a lithium bat-
tery is incorrectly replaced. Replace only
with the same or equivalent type.
Recommended battery: CR2025 or equivalent.
4Close the lid securely.
5. Press the
button, then thebutton two or three times to check the key-
fob operation.
If the battery is removed for any reason
other than replacement, perform step 5. ● An improperly disposed battery can
hurt the environment. Always confirm
local regulations for battery disposal.
● The keyfob is water-resistant; how-
ever, if it does get wet, immediately
wipe completely dry.
● The operational range of the keyfob
extends to approximately 33 ft (10 m)
from the vehicle. This range may vary
with conditions.
