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
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

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)

Engine coolant must be disposed of prop-
erly. Check your local regulations.
For additional information on changing the
Cummins 5.0L engine coolant, refer to the
“Titan Diesel Owner’s Manual”.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
15 minutes for the oil to drain back
into the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert 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 operating oil level range. If the
oil level is below the L (Low) mark
A,
remove the oil filler cap and pour rec-
ommended 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 sever-
ity of operating conditions.

WINDSHIELD-WASHER FLUID
RESERVOIR
Fill the windshield-washer fluid reservoir
periodically. Add windshield-washer fluid
when the low windshield-washer fluid
warning light (if so equipped) comes on or
the “Low Washer Fluid” warning message (if
so equipped) shows on the vehicle infor-
mation display.
To fill the windshield-washer fluid reservoir,
lif t the cap off the reservoir and pour the
windshield-washer fluid into the reservoir
opening.Add a washer solvent to the washer for
better cleaning. In the winter season, add a
windshield washer antifreeze. Follow the
manufacturer’s instructions for the mix-
ture ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of windshield-washer fluid.
Recommended fluid is Genuine NISSAN
Windshield Washer Concentrate Cleaner &
Anti-freeze or equivalent.
CAUTION
∙ Do not substitute engine antifreeze
coolant for windshield-washer fluid.
This may result in damage to the
paint.
∙ Do not fill the windshield-washer fluid reservoir with washer fluid concen-
trates at full strength. Some methyl
alcohol based washer fluid concen-
trates may permanently stain the
grille if spilled while filling the
windshield-washer fluid reservoir. ∙ Pre-mix washer fluid concentrates
with water to the manufacturer’s rec-
ommended levels before pouring the
fluid into the windshield-washer fluid
reservoir. Do not use the windshield-
washer fluid reservoir to mix the
washer fluid concentrate and water.LDI2879

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.
