CLUTCH FLUID (if so equipped)
Check the clutch fluid level in the reservoir
(manual transmissions only) . If the fluid level is
below the MIN line, add Genuine NISSAN Super
Heavy Duty Brake Fluid or equivalentDOT 3fluid
up to the MAX line. If fluid must be added fre-
quently, the system should be checked by a
NISSAN dealer.

information, refer to “Capacities and recom-
mended fuel/lubricants” in the “Technical and
consumer information” section of this manual.
WINDSHIELD-WASHER FLUID
RESERVOIR
Fill the windshield-washer fluid reservoir periodi-
cally. Add windshield-washer fluid when the low
windshield-washer fluid warning light (if so
equipped) comes on.
To fill the windshield-washer fluid reservoir, lift
the cap off the reservoir and pour the windshield-
washer fluid into the reservoir opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a windshield
washer antifreeze. Follow the manufacturer’s in-
structions for the mixture ratio. Refill the reservoir more frequently when driving
conditions require an increased amount of
windshield-washer fluid.
Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Anti-
freeze or equivalent.
CAUTION
●
Do not substitute engine anti-freeze
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. ●
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, see “Jump starting”
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.
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.

WARNING
●Operating the engine with the air
cleaner removed can cause you or oth-
ers to be burned. The air cleaner not
only cleans the air, it stops the flame if
the engine backfires. If it isn’t there, and
the engine backfires, you could be
burned. Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed.
● Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.
IN-CABIN MICROFILTER (if so
equipped)
The in-cabin microfilter restricts the entry of air-
borne dust and pollen particles and reduces
some objectionable outside odors. The filter is
located behind the glove box. Refer to the
“NISSAN Service and Maintenance Guide” for
change intervals.
To replace the filter, perform the following proce-
dure: 1. Open the glove box and press in on the
sides so that it will open completely allowing
it to hang by the cord. 2. Gently lift up on the tab
1.
3. Pull the filter cover toward you and then down
2.
4. Remove the old filters

NOTE:
The filters are marked with air flow arrows.
The end of the filter with the arrow should
face the rear of the vehicle. The arrows
should face downward. 5. Insert the first new filter into the housing and slide it over to the right. Insert the second
new filter into the housing.

If your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a washer
solution or a mild detergent. Your windshield is
clean if beads do not form when rinsing with clear
water.
Clean each blade by wiping it with a cloth soaked
in a washer solution or a mild detergent. Then
rinse the blades with clear water. If your wind-
shield is still not clear after cleaning the blades
and using the wiper, replace the blades.
CAUTION
Worn windshield wiper blades can dam-
age the windshield and impair driver
vision.
REPLACING
Replace the wiper blades if they are worn.
1. Lift the wiper arm away from the windshield.
2Push the release tab, then move the wiper
blade down the wiper arm to remove.
3Remove the wiper blade.
4. Insert the new wiper blade onto the wiper arm until it clicks into place.
5. Rotate the wiper blade so the dimple is in the groove.
