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-

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

burned. Do not drive with the air cleaner
removed, and be careful when working

Your NISSAN has been designed to have mini-
mum maintenance requirements with long ser-
vice intervals to save you both time and money;
however, some day-to-day and regular mainte-
nance is essential to maintain your NISSAN’s
good mechanical condition as well as its emis-
sions 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 mainte-
nance chain.
GENERAL MAINTENANCE
General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
maintenance 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 you,
a qualified technician or, if you prefer, a NISSAN
dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this section are
required to be serviced at regular intervals. How-
ever 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 corrected. It is recommended that
you visit a NISSAN dealer for this service.
NISSAN technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips and in-dealership training programs. They
are completely qualified to work on NISSAN ve-
hiclesbefore they work on your vehicle rather
than after they have worked on it.
You can be confident that a NISSAN dealer’s
service department performs excellent service to
meet the maintenance requirements on your ve-
hicle — in a reliable and economical way. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause, or it is
recommended that you visit a NISSAN dealer to
do it promptly. In addition, it is recommended that
you visit a NISSAN dealer if you think that repairs
are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” in “Do-it-yourself” section of this manual.
