.Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire
wear and lowers fuel economy.
. Use the recommended viscosity en-
gine oil. (See “Engine oil and oil filter
recommendation” (P.10-5).) If any malfunction occurs in the Intelligent
4x4 system while the engine is running,
warning messages appear in the vehicle
information display.

MOST COMMON FACTORS CON-
TRIBUTING TO VEHICLE CORRO-
SION
.The accumulation of moisture-retain-
ing dirt and debris in body panel
sections, cavities, and other areas.
. Damage to paint and other protective
coatings caused by gravel and stone
chips or minor traffic accidents.
ENVIRONMENTAL FACTORS INFLU-
ENCE THE RATE OF CORROSION
Moisture
Accumulation of sand, dirt and water on
the vehicle body underside can acceler-
ate corrosion. Wet floor coverings will not
dry completely inside the vehicle, and
should be removed for drying to avoid
floor panel corrosion.
Relative humidity
Corrosion will be accelerated in areas of
high relative humidity, especially those
areas where the temperatures stay above
freezing where atmospheric pollution ex-
ists, or where road salt is used.
Temperature
A temperature increase will accelerate
the rate of corrosion to those parts which
are not well ventilated.
Air pollution
Industrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use will accelerate the corrosion process.
Road salt will also accelerate the disin-
tegration of paint surfaces.
TO PROTECT YOUR VEHICLE FROM
CORROSION
.Wash and wax your vehicle often to
keep the vehicle clean.
. Always check for minor damage to the
paint and repair it as soon as possible.
. Keep drain holes at the bottom of the
doors open to avoid water accumula-
tion.
. Check the underbody for accumula-
tion of sand, dirt or salt. If present,
wash with water as soon as possible.
CAUTION
.NEVER remove dirt, sand or other
debris from the passenger com-
partment by washing it out with a
hose. Remove dirt with a vacuum cleaner.
. Never allow water or other liquids
to come in contact with electronic
components inside the vehicle as
this may damage them.
Chemicals used for road surface deicing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor
pan and fenders.
In winter, the underbody must be
cleaned periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, it is recommended you consult a
NISSAN dealer.

CORROSION PROTECTION

8-2Do-it-yourself
When performing any inspection or main-
tenance work on your vehicle, always
take care to prevent serious accidental
injury to yourself or damage to the
vehicle. The following are general precau-
tions which should be closely observed.
WARNING
.Park the vehicle on a level sur-
face, apply the parking brake
securely and block the wheels to
prevent the vehicle from moving.
Move the shift lever to the P
(Park) position (CVT model) or
the shift lever to the N (Neutral)
position (MT model).
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other
moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle. .
Always wear eye protection
whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed space such as a garage,
be sure there is proper ventilation
for exhaust gases to escape.
. Never get under the vehicle while
it is supported only by a jack. If it
is necessary to work under the
vehicle, support it with safety
stands.
. Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
you visit a NISSAN dealer for
service of the fuel filter or fuel
lines.
. Do not work under the hood while
the engine is hot. Always turn off
the engine and wait until it cools
down.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other
moving parts.
. Keep smoking materials, flame
and sparks away from fuel and
the battery. .
On gasoline engine models with
the Multiport Fuel Injection (MFI)
system, the fuel filter and fuel
lines should be serviced because
the fuel lines are under high
pressure even when the engine
is turned off. It is recommended
that you visit a NISSAN dealer for
this service.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition
switch is in the OFF position and
the engine is not running. To
avoid injury, always disconnect
the negative battery cable before
working near the fan.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, engine
coolant, and/or other vehicle
fluids can hurt the environment.
Always conform to local regula-
tions for disposal of vehicle fluids.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
MAINTENANCE PRECAUTIONS

JVM0378XExample
To remove the filter, unlatch the retaining
clips, and pull the coverupward.
The air cleaner filter should not be
cleaned and reused. Replace it according
to the maintenance schedule shown in
the “9. Maintenance and schedules” sec-
tion. When replacing the filter, wipe the
inside of the air cleaner housing and the
cover with a damp cloth.
WARNING
. Operating the engine with the air
cleaner filter off can cause you or
others to be burned. The air cleaner filter not only cleans the
intake air, it also stops flame if
the engine backfires. If the air
cleaner filter is not installed and
the engine backfires, you could
be burned. Never drive with the
air cleaner filter off. Be cautious
working on the engine when the
air cleaner filter is off.
. Never pour fuel into the throttle
body or attempt to start the
engine with the air cleaner re-
moved. Doing so could result in
serious injury.

9-4Maintenance and schedules
Steering wheel:Check for changes in the
steering conditions, such as excessive
free play, hard steering or strange noises.
Warning lights and chimes: Make sure
that all warning lights and chimes are
operating properly.
Windshield defroster: Check that the air
comes out of the defroster outlets prop-
erly and in sufficient quantity when oper-
ating the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washers operate
properly and that the wipers do not
streak.
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*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition 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 condi-
tions such as: 1.
Installation or extended use of elec-
tronic accessories that consume
battery 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 and clutch fluid level*: Make sure
that the brake and clutch fluid level is
between the MAX and MIN lines on the
reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belt*: Make sure that the
drive belt is not frayed, worn, cracked or
oily.
Engine oil level*: Check the level after
parking the vehicle on a level surface and
turning off the engine. Wait more than 10
minutes for the oil to drain back into the
oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected. It is recommended you visit a
NISSAN dealer for this service. (See “Pre-
cautions when starting and driving” (P.5- 4) for exhaust gas (carbon monoxide).)
Fluid leaks:
Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks
or if gasoline fumes are evident, check for
the cause and have it corrected immedi-
ately.
Radiator and hoses: Check the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, 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
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt
may accumulate. For additional informa-
tion, see “Cleaning exterior” (P.7-2).
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
scheduled maintenance items that
should be regularly checked or replaced.
The maintenance schedule indicates at
which mileage/time intervals each item
requires service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day op-
eration. Refer to “General maintenance”
(P.9-2).
Items marked with “*” are recommended
by NISSAN for reliable vehicle operation.
