THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
● Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
CAUTION
●Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants. ●
Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly. It is recommended that you
visit a NISSAN dealer for this service.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately 1 minute and then remain continuously
illuminated. This sequence will continue upon
Starting and driving5-3

●Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent maintenance
may be required. For additional infor-
mation, refer to “Periodic maintenance”
in the “Maintenance and schedules”
section of this manual.WARNING
●Never remove the ignition key or place
the ignition switch in the LOCK position
while driving. The steering wheel will
lock (for models with a steering lock
mechanism) . This may cause the driver
to lose control of the vehicle and could
result in serious vehicle damage or per-
sonal injury.
AUTOMATIC TRANSMISSION (if so
equipped)
The ignition lock is designed so the ignition
switch cannot be placed in the LOCK position
and the key removed until the shift lever is moved
to the P (Park) position.
When removing the key from the ignition, make
sure the shift lever is in the P (Park) position.
If the shift lever is not returned to P (Park) posi-
tion, the ignition switch cannot be moved to the
LOCK position.

SEAT BELTS
The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solution.
Allow the belts to dry completely in the shade
before using them. For additional information,
refer to “Seat belt maintenance” in the “Safety-
–Seats, seat belts and supplemental restraint
system” section of this manual.
WARNING
Do not allow wet seat belts to roll up in the
retractor. NEVER use bleach, dye or
chemical solvents to clean the seat belts,
since these materials may severely
weaken the seat belt webbing.
MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
Most vehicle corrosion is caused by:● the accumulation of moisture-retaining dirt
and debris in body panel sections, cavities,
and other areas
● damage to paint and other protective coat-
ings caused by gravel and stone chips or
minor traffic collisions
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on the ve-
hicle body underside can accelerate 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 and where
atmospheric pollution exists and road salt is
used.

When performing any inspection or maintenance
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 surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift lever to P
(Park) .
● Be sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
● If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
● It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key 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.
●
If you must run the engine in an en-
closed 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 neces-
sary to work under the vehicle, support
it with safety stands.
●
Keep smoking materials, flame and sparks
away from the fuel tank and battery.
● On gasoline engine models, the fuel
filter or fuel lines should be serviced. It
is recommended that you visit a
NISSAN dealer for this service because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
●Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down. ●
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
● Never leave the engine or the transmis-
sion related component harness con-
nector disconnected while the ignition
switch is in the ON position.
● Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
This “Do-it-yourself” section gives instructions
regarding only those items which are relatively
easy for an owner to perform.
A Genuine NISSAN service manual is also avail-
able. For additional information, refer to “Owner’s
Manual/Service Manual order information” in the
“Technical and consumer information” section of
this manual.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage. If in doubt about any servicing, it
is recommended that you have it done by a
NISSAN dealer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round antifreeze and
coolant protection. The antifreeze solution con-
tains rust and corrosion inhibitors. Additional en-
gine cooling system additives are not necessary.
WARNING
●Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused
by high pressure fluid escaping from
the radiator. For additional information
on precautions, refer to “If your vehicle
overheats” in the “In case of emer-
gency” section of this manual.
● The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a Genuine
NISSAN radiator cap.
CAUTION
●Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.
● When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C) . If additional freeze protection
is needed due to weather where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is
used, follow the coolant manufacturer’s
instructions to maintain minimum anti-
freeze protection to -34° F (-37° C) . The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling
system. ●
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km) or
7 years. Mixing any other type of cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) , includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green) , or the use
of non-distilled water will reduce the
life expectancy of the factory-fill cool-
ant. For additional information, refer to
the Maintenance and schedules sec-
tion of this manual.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and applythe parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
10 minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re- insert it all the way. 5. Remove the dipstick again and check the oil
level. It should be between the H (High) and
L (Low) marksB. This is the normal oper-
ating oil level range. If the oil level is below
the L (Low) mark
A, remove the oil filler cap
and pour recommended oil through the
opening. Do not overfill
C.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the severity
of operating conditions.
