Do not use excessive force.
9. Refill engine with recommended oil and install the oil filler cap securely.
CAUTION
The dipstick must be inserted in place to
prevent oil spillage from the dipstick hole
while filling the engine with oil.
See “Capacities and recommended fuel/lubricants”
(P.9-2) for drain and
refill capacity. The drain and refill
capacity depends on the oil tempera-
ture and drain time. Use these specifi-
cations for reference only. Always use
the dipstick to determine 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.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
After the operationY51D-V-E01-790CC92C-2688-443C-80B6-74DD163C016F1.Install the engine undercover into

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 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 reser-
voir tank.
. Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid into the window washer reservoir tank.
Do not use the window washer reservoir
tank to mix the washer fluid concentrate
and water.
Y51D-V-E01-53727028-85F3-446D-8050-B21208C99FC8.
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
discharging it.
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 electro-
nic 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. Hydrogen gas gener-

CAUTION
. Do not ground accessories directly 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 en-
gine running to avoid discharging 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.

WARNING
.Operating the engine with the air
cleaner removed can cause you or others
to be burned. The air cleaner not only
cleans the air, it stops 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.

CLEANINGY51D-V-E01-7847FFC1-7DCA-4EE2-B775-CA92E386F50AIf 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 wind-
shield.
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 blade with clear
water. If your windshield is still not clear
after cleaning the blades and using the
wiper, replace the blades.
Worn windshield wiper blades can damage
the windshield and impair driver vision.
