●Keep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
● Make certain the terminal connections are
clean and securely tightened.
● If the vehicle is not to be used for 30 days or
longer, disconnect the negative (-) battery
terminal cable to prevent discharge.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as: 1. Installation or extended use of electronic accessories that consume battery power
when the engine is not running (Phone char-
gers, 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. Hydrogen
gas generated by the battery is explo-
sive. Explosive gases can cause blind-
ness or injury. Do not allow battery fluid
to contact your skin, eyes, fabrics or
painted surfaces. Sulfuric acid can
cause blindness or injury. After touch-
ing a battery or battery cap, do not
touch or rub your eyes. Thoroughly
wash your hands. If the acid contacts
your eyes, skin or clothing, immediately
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 battery, al-
ways wear suitable eye protection and
remove all jewelry.
● Battery posts, terminals and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling. ●
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 screwdriver asshown. Use a cloth to protect the battery
case.
2. Check the fluid level in each cell. If it isnecessary to add fluid, add only distilled
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 start-
ing” in the “In case of emergency” section 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 service.

CAUTION
●Do not ground accessories directly to
the 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 measures the
amount of electrical discharge from the battery
and controls voltage generated by the generator. The current sensor
Ais located near the battery
along the negative battery cable. If you add elec-
trical 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. Cooling fan pulley
4. Air conditioner compressor pulley
5. Crankshaft pulley
6. Generator pulley
WARNING
Be sure the ignition key is in the OFF or
LOCK position before servicing drive belt.
The engine could rotate unexpectedly.

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 key fob.
● There is danger of explosion if a lithium bat-
tery is incorrectly replaced. Replace only
with the same or equivalent type.

● The key fob is water-resistant; how-
ever, if it does get wet, immediately
wipe completely dry.
● The operational range of the key fob
extends to approximately 33 ft (10 m)
from the vehicle. This range may vary
with conditions.
