When checking or replacement is required, we
recommend your NISSAN dealer for servicing.
CAUTION
●Use Genuine NISSAN Matic S ATF. If
Genuine NISSAN Matic S ATF is not
available, Genuine NISSAN Matic J ATF
may also be used.
● Using automatic transmission fluid
other than Genuine NISSAN Matic S
ATF or Matic J ATF will cause deteriora-
tion in driveability and automatic trans-
mission durability, and may damage the
automatic transmission, which is not
covered by the NISSAN new vehicle lim-
ited warranty.
The specified automatic transmission fluid is also
described on caution labels located in the engine
compartment. The fluid level should be checked using the HOT
MAX range on the power steering fluid reservoir
at fluid temperatures of 122° - 176°F (50° -
80°C) or using the COLD MAX range on the
power steering fluid reservoir at fluid tempera-
tures of 32° - 86°F (0° - 30°C) .
If the fluid is at or below the MIN line, add Genu-
ine NISSAN PSF. Remove the cap and fill
through the opening.
CAUTION
●
DO NOT OVERFILL.
● Recommended fluid is Genuine
NISSAN PSF or equivalent. For further brake and clutch fluid specification
information, refer to “Recommended
fluids/lubricants and capacities” in the “Technical
and consumer information” section of this
manual.
WARNING
●
Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated
fluid may damage the brake and clutch
(if so equipped) systems. The use of
improper fluids can damage the brake
and clutch system and affect the vehi-
cle’s stopping ability.
● Clean the filler cap before removing.
● Brake and clutch fluid is poisonous and

Refill the reservoir more frequently when driving
conditions require an increased amount of
windshield-washer fluid.
Recommended fluid is Genuine NISSAN
Windshield-Washer Concentrate Cleaner & An-
tifreeze or equivalent.
CAUTION
●Do not substitute engine antifreeze
coolant for windshield-washer solution.
This may result in damage to the paint.
● Do not fill the windshield-washer reser-
voir with washer fluid concentrates at
full strength. Some methyl alcohol
based washer fluid concentrates may
permanently stain the grille if spilled
while filling the windshield-washer
reservoir.
● Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the windshield-washer reservoir.
Do not use the windshield-washer res-
ervoir to mix the washer fluid concen-
trate and water. ●
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.
BATTERY
Maintenance and do-it-yourself8-17

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 for additional information. If the engine
does not start by jump starting, the battery may
have to be replaced. Contact a NISSAN dealer.
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.
