to 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
additionally more than 2/3 turn.

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
capacity depends on the oil temperature and drain time. Use these specifications for
reference only. Always use the dipstick to
determine the proper amount of oil in the
engine.

WINDSHIELD-WASHER FLUID
RESERVOIR
Fill the windshield-washer fluid reservoir
periodically. Add windshield-washer fluid
when the “Low Washer Fluid” warning (if so
equipped) appears in the vehicle informa-
tion display.
To check the fluid level with the dip tube,
use your finger to plug the center hole
Aof
the cap/tube assembly, then remove it
from the reservoir. If there is no fluid in the
dip tube, add fluid. 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.
WARNING
Antifreeze is poisonous and should be
stored carefully in marked containers
out of the reach of children.
CAUTION
∙ Do not substitute engine antifreeze
coolant for windshield-washer fluid.
This may result in damage to the
paint.
∙ Do not fill the windshield-washer fluid reservoir with washer fluid concen-
trates at full strength. Some methyl
alcohol based washer fluid concen-
trates may permanently stain the
grille if spilled while filling the
windshield-washer fluid reservoir.
∙ Pre-mix washer fluid concentrates with water to the manufacturer’s rec-
ommended levels before pouring the
fluid into the windshield-washer fluid
reservoir. Do not use the windshield-

ules” section of this manual. Do not service
iridium-tipped spark plugs by cleaning or
regapping.
∙ Always replace spark plugs with rec-
ommended or equivalent ones.

Some day-to-day and regular mainte-
nance is essential to maintain your vehicle
good mechanical condition, as well as its
emissions and engine performance.
It is the owner’s responsibility to make sure
that the scheduled maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
proper maintenance. You are a vital link in
the maintenance chain.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal
day-to-day operation. They are essential
for proper vehicle operation. It is your re-
sponsibility to perform these procedures
regularly as prescribed.
Performing general maintenance checks
requires minimal mechanical skill and only
a few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, a NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this sec-
tion are required to be serviced at regular
intervals. However under severe driving
conditions, additional or more frequent
maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and serviced. It is recom-
mended that you visit a NISSAN dealer for
this service.
NISSAN technicians are well-trained spe-
cialists and are kept up-to-date with the
latest service information through techni-
cal bulletins, service tips and training pro-
grams. They are completely qualified to
work on NISSAN vehiclesbeforework be-
gins.
If your vehicle is involved in a collision, it is
recommended that you ask your NISSAN
dealer where the nearest NISSAN Certified
Collision Center is located, or go to
http://collision.nissanusa.com. You can be confident that a NISSAN deal-
er’s service department can perform the
service needed to meet the maintenance
