When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions 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 ve-
hicle from moving. Move the shif t le-
ver to P (Park)
∙ Be sure the ignition switch is in the OFF or LOCK position when perform-
ing 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 jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙
The automatic engine cooling fan (if so
equipped) may come on at any time
without warning, even if the ignition
switch is in the OFF position and the
engine is not running. To avoid injury,
always disconnect the negative bat-
tery 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, sup-
port it with safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ Because the fuel lines on gasoline en- gine models are under high pressure
even when the engine is off, it is rec-
ommended that you visit a NISSAN
dealer for service of the fuel filter or
fuel lines.
CAUTION
∙ Do not work under the hood while theengine 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 igni-
tion switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer 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, it is recommended
that you have it done by a NISSAN dealer.

8-4Do-it-yourself

∙ If the battery is labeled "do not open" itis maintenance free and battery fluid
should not be checked. It is recom-
mended that you visit a NISSAN dealer
or a qualified specialist workshop to
confirm the battery’s performance.
∙ Keep the battery surface clean and dry. Clean the battery with a solution of bak-
ing soda and water.
∙ Make certain the terminal connections are clean and securely tightened.
∙ Push the ignition switch to the OFF po- sition and wait 2 minutes before dis-
connecting the battery.
∙ If the vehicle is not to be used for 30 days or longer, disconnect the nega-
tive (-) battery terminal cable to prevent
discharge.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as: 1. Installation or extended use of elec-
tronic accessories that consume bat- tery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.).
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
WARNING
∙ Do not expose the battery to flames, an electrical spark or a cigarette. Hy-
drogen gas generated by the battery
is explosive. Explosive gases can
cause blindness or injury. Do not allow
battery fluid to contact your skin,
eyes, fabrics or painted surfaces. Sul-
furic acid can cause blindness or in-
jury. Af ter touching a battery or bat-
tery cap, do not touch or rub your
eyes. Thoroughly wash your hands. If
the acid contacts your eyes, skin or
clothing, immediately flush with wa-
ter for at least 15 minutes and seek
medical attention. ∙ Do not operate the vehicle if the fluid
in the battery is low. Low battery fluid
can cause a higher load on the battery
which can generate heat, reduce bat-
tery life, and in some cases lead to an
explosion.
∙ When working on or near a battery, always wear suitable eye protection
and remove all jewelry.
∙ Battery posts, terminals and related accessories contain lead and lead
compounds. Wash hands af ter
handling.
∙ This vehicle uses a special battery. If the 12-volt battery needs to be re-
placed, use a 12-volt battery of the
same design.
∙ Keep battery out of the reach of children.
∙ Do not tip the battery. Keep the vent caps tight and the battery level.

1. Remove the vent caps with a screw-driver as shown. Use a cloth to protect
the battery case.
2. Check the fluid level in each cell. If it isnecessary to add fluid, add only dis-
tilled water to bring the level up to the
bottom of the filler opening. Do not
overfill. Reinstall the vent caps. Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, refer to “Jump
starting” in the “In case of emergency” sec-
tion of this manual. If the engine does not
start by jump starting, the battery may
have to be replaced. It is recommended
that you visit a NISSAN dealer for this ser-
vice.

CAUTION
∙ Do not ground accessories directly tothe battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
∙ Use electrical accessories with the en- gine running to avoid discharging the
vehicle battery.
Your vehicle is equipped with a variable
voltage control system. This system mea-
sures the amount of electrical discharge
from the battery and controls voltage gen-
erated by the generator. The current sensor is located near the bat-
tery along the negative battery cable. If you
add electrical accessories to your vehicle,
be sure to ground them to a suitable body
ground such as the frame or engine block
area.1. Power steering fluid pump pulley
2. Automatic belt tensioner pulley
3. Water pump pulley
4. Cooling fan pulley
5. Air conditioner compressor pulley
6. Crankshaf t pulley
7. Generator pulley
WARNING
Be sure the ignition switch is in the OFF
or LOCK position before servicing drive
belt. The engine could rotate
unexpectedly.
