5-40Starting and driving

∙ Keep your engine tuned up.
∙ Follow the recommended scheduledmaintenance.
∙ 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.
∙ For vehicles equipped with
, use
4H or 4L position only when necessary.
4-wheel drive operation lowers fuel
economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer
information” section of this manual.
WARNING
∙ For 4WD equipped vehicles, do not at-tempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury.
∙ Do not attempt to test a 4WD equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions
testing), or similar equipment even if
the other two wheels are raised off the
ground. Make sure you inform test fa-
cility personnel that your vehicle is
equipped with 4WD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drive-
train damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal
injury.
CAUTION
∙ Do not drive the vehicle in the 4H or4LO position on dry hard surface
roads. Driving on dry, hard surfaces in
4H or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD warning light or vehicle in-
formation display warning message
turns on when you are driving on dry
hard surface roads:
– in the 4H position, shif t the 4WD shif t switch to 2WD.
– in the 4LO position, stop the ve- hicle, move the shif t lever to the N
(Neutral) position with the brake
pedal depressed, and shif t the
4WD shif t switch to 2WD.

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 fol-
lowing are general precautions 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 ve-
hicle from moving. Move the shif t le-
ver to P (Park)
∙ Be sure the ignition switch is in the OFF or LOCK position when perform-
ing 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 jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙
The automatic engine cooling fan (if so
equipped) 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 bat-
tery 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, sup-
port it with safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ Because the fuel lines on gasoline en- gine models are under high pressure
even when the engine is off, it is rec-
ommended that you visit a NISSAN
dealer for service of the fuel filter or
fuel lines.
CAUTION
∙ Do not work under the hood while theengine 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 automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and

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. Addi-
tional engine cooling system additives are
not necessary.
WARNING
∙ Never remove the radiator or coolantreservoir 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 informa-
tion on precautions, refer to “If your
vehicle overheats” found in the “In
case of emergency ” section of this
manual.
∙ The radiator is equipped with a pres- sure type radiator cap. To prevent en-
gine damage, it is recommended that
you use only a Genuine NISSAN radia-
tor cap.
CAUTION
∙ Never use any cooling system addi-tives such as radiator sealer. Additives
may clog the cooling system and
cause damage to the engine, trans-
mission and/or cooling system.
∙ When adding or replacing coolant, it is recommended that you use only
Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-
diluted to provide antifreeze protec-
tion to -34° F (-37° C). If additional
freeze protection is needed due to
weather where you operate your ve-
hicle, add Genuine NISSAN Long Life
Antifreeze/Coolant (blue) concen-
trate following the directions on the
container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s in-
structions to maintain minimum anti-
freeze protection to -34° F (-37° C). The use of other types of coolant solu-
tions 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
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue),
including Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the use
of non-distilled water may reduce the
life expectancy of the factory-fill cool-
ant. For additional information, refer
to the "Maintenance and schedules"
section of this manual.
For additional information on the Cum-
mins 5.0L engine cooling system, refer to
the “Titan Diesel Owner’s Manual”.
ENGINE COOLING SYSTEM
Do-it-yourself8-5

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
B, add coolant
to the MAX level
A. If the reservoir is empty,
check the coolant level in the radiator
when the engine is cold. If there is insuffi-
cient coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to the MAX
level
A. 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 may reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to “Maintenance
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 radiator or engine coolant reservoir cap when the en-
gine is hot. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator.
∙ 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.VK56VD engine (non-XD model)
