CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
10 minutes for the oil to drain back
into the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check
the oil level. It should be between the H
(High) and L (Low) marksB. This is the
normal operating oil level range. If the
oil level is below the L (Low) mark
A,
remove the oil filler cap and pour rec-
ommended oil through the opening.
Do not overfill
C.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-

CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
WARNING
∙Prolonged and repeated contact with
used engine oil may cause skin cancer.
∙ Try to avoid direct skin contact withused oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep used engine oil out of reach of children. 4. Loosen the oil filter with an oil filter
wrench by turning it counterclockwise.
Remove the oil filter by turning it by
hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old gasket mate-
rial remaining on the sealing surface of
the engine. Failure to do so could lead to
an oil leak and engine damage.
∙ The dipstick must be inserted in placeto prevent oil spillage from the dip-
stick hole when filling the engine with
oil.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten ad-
ditionally more than 2/3 turn.
Oil filter tightening torque: 11 to 15 f t-lb (14.7 to 20.6 N·m) 8. Clean and re-install the drain plug with
a new washer. Securely tighten the
drain plug with a wrench. Do not use
excessive force.
Drain plug tightening torque: 22 to 29 f t-lb (29 to 39 N·m)
9. Refill the engine with the recom- mended oil through the oil filler open-
ing, and install the oil filler cap securely.
For additional information about drain and
refill capacity, refer to “Recommended
fluids/lubricants and capacities” in the
“Technical and consumer information” sec-
tion of this manual. The drain and refill ca-
pacity depends on the oil temperature and
drain time. Use these specifications for ref-
erence only. Always use the dipstick to de-
termine the proper amount of oil in the
engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required. Turn the engine off
and wait more than 15 minutes. Check
the oil level with the dipstick. Add en-
gine oil if necessary.

Af ter the operation
1. Reinstall plate in reverse order of re-moval.
2. Lower the vehicle carefully to the ground.
∙ Dispose of waste oil and filter properly.
∙ Check your local regulations. When checking or replacement is required,
it is recommend that you visit a NISSAN
dealer for this service.
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 (or their equiva-
lents) will cause deterioration in
driveability and automatic transmis-
sion durability, and may damage the
automatic transmission, which is not
covered by the NISSAN New Vehicle
Limited 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 temperatures of 32° - 86°F (0° - 30°C).
If the fluid is at or below the MIN line, add
Genuine NISSAN PSF-II or equivalent to HOT
MAX or COLD MAX depending on system
fluid temperature. Remove the cap and fill
through the opening.

CLUTCH (if so equipped) FLUID
Check the fluid level in the reservoir. The
brake fluid reservoir is shared with the
clutch hydraulic system for manual trans-
missions. If the level is below the MIN line
B,
or the brake warning light comes on, add
Genuine NISSAN Super Heavy Duty Brake
Fluid or equivalent DOT 3fluid up to the
MAX line

WINDSHIELD-WASHER FLUID
RESERVOIR
Fill the windshield-washer fluid reservoir
periodically. Add windshield-washer fluid
when the low windshield-washer fluid
warning light (if so equipped) comes on.
To fill the windshield-washer fluid reservoir,
lif t 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 instructions for the mix-
ture ratio.
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 &
Antifreeze or equivalent.
CAUTION
∙Do not substitute engine antifreeze cool-
ant for windshield-washer solution. This
may result in damage to the paint.
∙ Do not fill the windshield-washer res-
ervoir 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 rec-
ommended levels before pouring the
fluid into the windshield-washer res-
ervoir. Do not use the windshield-
washer reservoir to mix the washer
fluid concentrate and water.

∙ 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.
∙ 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.
∙ 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.
∙ Keep battery out of the reach of children.
∙ Do not tip the battery. NOTE:
Do not try to open the top of the battery.
This battery is not equipped with remov-
able vent caps.
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
Ais located near the
battery along the negative battery cable. If
you add electrical accessories to your ve-
hicle, be sure to ground them to a suitable
body ground such as the frame or engine
block area.
