Your NISSAN has been designed to have
minimum maintenance requirements with
long service intervals to save you both time
and money; however, some day-to-day
and regular maintenance is essential to
maintain your NISSAN’s good mechanical
condition as well as its emissions and en-
gine 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 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 pre-
fer, 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 corrected. It is rec-
ommended that you visit a NISSAN dealer
for this service.
NISSAN technicians are well-trained spe-
cialists who are kept up-to-date with the
latest service information through techni-
cal bulletins, service tips and in-dealership
training programs. They are completely
qualified to work on NISSAN vehiclesbe-
fore they work on your vehicle rather than
af ter they have worked on it.
You can be confident that a NISSAN deal-
er’s service department performs excellent
service to meet the maintenance require-
ments on your vehicle — in a reliable and
economical way. During the normal day-to-day operation of
the vehicle, general maintenance should
be performed regularly as prescribed in
this section. If you detect any unusual
sounds, vibrations or smells, be sure to
check for the cause or have it checked
promptly. In addition, it is recommended
that you visit a NISSAN dealer if you think
that repairs are required.
When performing any checks or mainte-
nance work, closely observe the “Mainte-
nance precautions” in the “Do-it-yourself ”
section of this manual.

MAINTENANCE REQUIREMENTS GENERAL MAINTENANCE
9-2Maintenance and schedules

Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
Seat belts:Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel: Check for changes in the
steering system, such as excessive free-
play, hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield wiper and washer*: Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel). Battery* (for serviceable batteries):
Check the fluid level in each cell. The fluid
should be at the bottom of the filler open-
ing. Vehicles operated in high tempera-
tures or under severe conditions require
frequent checks of the battery fluid level.
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 elec-
tronic accessories that consume bat-
tery 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.
Brake fluid level*: Make sure that the brake
fluid level is between the MIN and MAX lines
on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold. Engine drive belts*:
Make sure the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
parking the vehicle on a level surface with
the engine off. Wait more than 10 minutes
for the oil to drain back into the oil pan.
Exhaust system: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration and damage. Tighten
connections or replace parts as necessary.
For additional information, refer to “Exhaust
gas (carbon monoxide)” in the “Starting and
driving” section of this manual.
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
fuel fumes are evident, check for the cause
and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
9-4Maintenance and schedules

Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise
rust may form on the floor pan, frame, fuel
lines and exhaust system. At the end of
winter, the underbody should be thor-
oughly flushed with plain water, in those
areas where mud and dirt may have accu-
mulated. For additional information, refer
to the “Appearance and care” section of this
manual.
Windshield-washer fluid*: Check that
there is adequate fluid in the reservoir.The following descriptions are provided to
give you a better understanding of the sched-
uled maintenance items that should be regu-
larly checked or replaced. The maintenance
schedule indicates at which mileage/time in-
tervals each item requires service.
Items marked with “*”are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform mainte-
nance on these items in order to maintain
the warranties which come with your
NISSAN. Other maintenance items and in-
tervals are required.
When applicable, additional information
can be found in the “Do-it-yourself ” section
of this manual.
NOTE: NISSAN does not advocate the use
of non-OEM approved af termarket flush-ing systems and strongly advises againstperforming these services on a NISSANproduct. Many of the af termarket flushingsystems use non-OEM approved chemi-cals or solvents, the use of which has notbeen validated by NISSAN.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to “Recom-
mended fluids/lubricants and capacities”
in the “Technical and consumer informa-
tion” section of this manual.
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive Belts*: Check engine drive belts for
wear, fraying or cracking and for proper
tension. Replace any damaged drive belts.
Engine Air Filter: Replace at specified in-
tervals. When driving for prolonged periods
in dusty conditions, check/replace the filter
more frequently.

Long Life Antifreeze/Coolant (blue) or
equivalent with the proper mixture. (For ad-
ditional information on the proper mixture
for your area, refer to Engine cooling system”
in the “Do-it-yourself ” section of this manual
or the “Titan Diesel Owner’s Manual”.)
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the

9-6Maintenance and schedules

To help ensure smooth, safe and economi-
cal driving, NISSAN provides two mainte-
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 in normal temperatures or less than
10 miles in freezing temperatures.
∙ Stop-and-go traffic in hot weather or low speed driving for long distances.
∙ Driving in dusty conditions or on rough, muddy or salt-spread roads.
∙ Towing a trailer, or using a camper or car-top carrier.
OIL CHANGE MONITOR (diesel
engine only)
This vehicle is equipped with oil change
monitor. It calculates engine oil and filter
change interval base on driving conditions.
Driving in severe conditions will shorten the
engine oil and filter change interval. When
the Engine Oil – Service Due Now warning
appears in the vehicle information display,
the engine oil and filter need to be replaced.
NOTE:
For vehicles operated in Canada, both
standard and severe maintenance items
should be performed at every interval.
