Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
OB, add coolant
to the MAX level
OA.
This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water will reduce the life ex-
pectancy of the factory-fill coolant. For ad- ditional information, refer to the “Mainte-
nance and schedules” section of this
manual.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment check locations” in this
section.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
• To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
• Never remove the engine coolant
reservoir cap when the engine is hot.
Serious burns could be caused by
high pressure fluid escaping from the
system. •
Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand
cleaner as soon as possible.
• Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.

Some day-to-day and regular mainte-
nance is essential to maintain your vehi-
cle’s 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.

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
requirements on your vehicle. During the normal day-to-day operation of
the vehicle, general maintenance should
be performed regularly as prescribed in
