cause personal injury.
1. Remove the engine compartment cover, if necessary. See “Engine com-
partment check locations” (P.8-3).
2. If the booster battery is in another vehicle
, position the two vehicles (and) to bring their batteries into
close proximity to each other. Do not allow the two vehicles to
touch.
3. Apply parking brake. Move the shift lever to the P (Park) position. Switch
off all unnecessary electrical systems
(light, heater, air conditioner, etc.).
4. Remove vent caps on the battery (if so equipped). Cover the battery with a
firmly wrung out moist cloth

8. After starting your engine, carefullydisconnect the negative cable and
then the positive cable (
???).
9. Replace the vent caps (if so equipped). Be sure to dispose of the cloth used to
cover the vent holes as it may be
contaminated with corrosive acid.
10. Put the battery cover on. Do not attempt to start the engine by
pushing.CAUTION
.
Automatic transmission models
cannot be push-started or tow-
started. Attempting to do so may
cause transmission damage.
. Three way catalyst equipped
models should not be started by
pushing since the three way cat-
alyst may be damaged.
. Never try to start the vehicle by
towing it; when the engine starts,
the forward surge could cause
the vehicle to collide with the
tow vehicle.
CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle
fire.
. To avoid the danger of being
scalded, never remove the radia-
tor cap or coolant reservoir cap
while the engine is still hot. When
the radiator cap or coolant reser-
voir cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc., take
the following steps:
1. Move the vehicle safely off the road, apply the parking brake and move the
shift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the heater and air condi- tioner. Open all the windows, move
the heater or air conditioner tempera-
ture control to maximum hot and fan

8-2Do-it-yourself
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 following are general precau-
tions which should be closely observed.
WARNING
.Park the vehicle on a level sur-
face, apply the parking brake
securely and block the wheels to
prevent the vehicle from moving.
Move the shift lever to P (Park).
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or auto-
matic transmission related com-
ponent harnesses disconnected
while the ignition switch is in the
ON position.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection
whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed 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 necessary to work under the
vehicle, support it with safety
stands.
. Keep smoking materials, flame
and sparks away from fuel tank
and the battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid
injury, always disconnect the ne-
gative battery cable before work-
ing near the fan. .
Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
you visit a NISSAN dealer for
service of the fuel filter or fuel
lines.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local regulations for
disposal of vehicle fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items
which are relatively easy for an owner to
perform.
A genuine NISSAN Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-40).)
You should be aware that incomplete or
improper servicing may result in operat-
ing difficulties or excessive emissions, and
MAINTENANCE PRECAUTIONS

could affect your warranty coverage.If in
doubt about any servicing, it is recom-
mended you have it done by a NISSAN
dealer.

ENGINE COMPARTMENT CHECK LOCATIONS

Add a washer solvent to the washer for
better cleaning. In the winter season, add
a windshield washer antifreeze. Follow
the manufacturer’s instructions for the
mixture ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of window washer fluid.
Recommended fluid is Genuine NISSAN
Windshield Washer Concentrate Cleaner
& Antifreeze or equivalent.
CAUTION
.Do not substitute engine anti-
freeze coolant for window
washer solution. This may result
in damage to the paint.
. Do not fill the window washer
reservoir tank with washer fluid
concentrates at full strength.
Some methyl alcohol based
washer fluid concentrates may
permanently stain the grille if
spilled while filling the window
washer reservoir tank.
. Pre-mix washer fluid concen-
trates with water to the manu-
facturer’s recommended levels
before pouring the fluid into the
window washer reservoir tank. Do not use the window washer re-
servoir tank to mix the washer
fluid concentrate and water.
.
Keep the battery surface clean and
dry. Clean the battery with a solution
of baking soda and water.
. Make certain the terminal connec-
tions are clean and securely tightened.
. If the vehicle is not to be used for 30
days or longer, disconnect the nega-
tive (−) battery terminal cable to pre-
vent discharging it.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start condi-
tions such as:
1. Installation or extended use of elec-
tronic accessories that consume
battery 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 or electrical sparks. Hy-
drogen gas generated by the
battery is explosive. Do not allow
battery fluid to contact your skin,

eyes, fabrics, or painted surfaces.
After 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, immedi-
ately flush with water 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 battery life,
and in some cases lead to an
explosion.
. When working on or near a bat-
tery, always wear suitable eye
protection and remove all jew-
elry.
. Battery posts, terminals and re-
lated accessories contain lead
and lead compounds. Wash
hands after handling.
. Keep the battery out of the reach
of children.
DI0137MA
Check the fluid level in each cell (Remove
the battery cover if it is necessary). It
should be between the UPPER LEVEL
and LOWER LEVELlines.
If it is necessary to add fluid, add only
distilled water to bring the level to the
indicator in each filler opening. Do not
overfill.
SDI1480C
1. Remove the cell plugs.
2. Add distilled water up to the UPPER LEVEL
line.
If the side of the battery is not clear,
check the distilled water level by
looking directly above the cell; the
condition
indicates OK and the
conditionsneeds more to be added.
3. Tighten cell plugs
.
Vehicles operated in high temperatures
or under severe conditions require fre-
quent checks of the battery fluid level.

JUMP STARTING
If jump starting is necessary, see “Jump
starting” (P.6-12). If the engine does not
start by jump starting, the battery may
have to be replaced. It is recommended
you visit a NISSAN dealer for this service.CAUTION
.Do not ground accessories di-
rectly to the battery terminal.
Doing so will bypass the variable
voltage control system and the
vehicle battery may not charge
completely.
. Use electrical accessories with
the engine running to avoid dis-
charging the vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.
