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 fully qualified to work on
NISSAN vehiclesbeforework begins.
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

nance schedules that may be used, de-
pending upon the conditions in which you
usually drive. These schedules contain
both distance and time intervals, up to
120,000 miles (192,000 km)/144 months. For
most people, the odometer reading will in-
dicate when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals
shown in the schedule.
Af ter 120,000 miles (192,000 km)/
144 months, continue maintenance at
the same mileage/time intervals.ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditionsshould be per-
formed on vehicles that are driven under
especially demanding conditions. Addi-
tional maintenance items should be per-
formed if you primarily operate your vehicle
under the following conditions:
∙ Repeated short trips of less than 5 miles (8 km).
∙ Repeated short trips of less than 10 miles (16 km) with outside tempera-
tures remaining below freezing.
∙ Operating in hot weather in stop- and-go “rush hour” traffic.
∙ Extensive idling and/or low speed driv- ing for long distances, such as police,
taxi or door-to-door delivery use.
∙ Driving in dusty conditions.
∙ Driving on rough, muddy or salt spread roads.
∙ Using a car-top carrier.
OIL CONTROL SYSTEM
Your vehicle is equipped with oil control
system. It calculates engine oil and filter
change intervals based on driving condi-
tions. Driving in the following severe condi-
tions will shorten the engine oil and filter
change interval.
MAINTENANCE SCHEDULES
Maintenance and schedules9-7

Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter
change intervals depend upon how you
use your vehicle.
Operation under the following conditions
may require more frequent oil and filter
changes:∙ repeated short distance driving at cold outside temperatures
∙ driving in dusty conditions
∙ extensive idling
∙ stop and go commuting
For additional information, refer to the
“Maintenance and schedules” section of

AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your
NISSAN vehicle must be charged with the
refrigerant HFO-1234yf (R-1234yf ) and
NISSAN A/C system oil Type PAG
(VC100YF oil) or the exact equivalents.
CAUTION
The use of any other refrigerant or oil
will cause severe damage to the air con-
ditioning system and will require the re-
placement of all air conditioner system
components.
The refrigerant HFO-1234yf (R-1234yf ) in
your NISSAN vehicle does not harm the
earth’s ozone layer. Although this refriger-
ant does not affect the earth’s atmo-
sphere, certain government regulations re-
quire the recovery and recycling of any
refrigerant during automotive air condi-
tioner system service. Air conditioner sys-
tem should only be serviced by trained and
certified technicians to ensure proper and
safe operation (SAE J2845). A NISSAN dealer
has the trained technicians and equip-
ment needed to recover and recycle your
air conditioner system refrigerant. Only
new and SAEJ2842 certified evaporator(s)
shall be used as replacement parts. A damaged or leaking air conditioning
evaporator shall never be repaired or re-
placed with one removed from a used or
salvaged vehicle. To replace a damaged or
leaking evaporator, use only new and SAE
J2842 certified evaporator(s). It is recom-
mended that you visit a NISSAN dealer
when servicing your air conditioner sys-
tem.
