DIESEL EXHAUST FLUID (DEF) FILL
CAP
CAUTION
∙ Overfilling your DEF tank can causedamage to the tank. ∙ DEF will freeze below 12°F (-11°C); how-
ever, your vehicle is equipped with an
automatic preheating system, which
allows the DEF system to operate be-
low 12°F (-11°C). When the vehicle is not
in operation for an extended period of
time with temperatures at or below
12°F (-11°C), the DEF tank could freeze.
In this condition, adding DEF will not
change the gauge level and added
DEF will not reach the pump, because
it will sit on top of the frozen layer. Move the vehicle to a warm location to
thaw the DEF completely for the
gauge to read accurately and allow
new DEF to reach the pump. If the tank
is overfilled and freezes, it could be
damaged, therefore do not overfill in
sustained cold conditions below 12°F
(-11°C).
∙ Do not put DEF into the fuel tank. This can cause engine damage that is not
covered by your vehicle’s warranty.
∙ Immediately wipe away any DEF that has spilled on painted surfaces with
water and a damp cloth to prevent
damage to the paint.

To start your engine with a booster battery,
the instructions and precautions below
must be followed.
WARNING
∙ If done incorrectly, jump starting canlead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
∙ Explosive hydrogen gas is always present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
∙ Do not allow battery fluid to come into contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a
corrosive sulfuric acid solution which
can cause severe burns. If the fluid
should come into contact with any-
thing, immediately flush the con-
tacted area with water.
∙ Keep battery out of the reach of children.
∙ The booster battery must be rated at 12 volts. Use of an improperly rated
battery can damage your vehicle. ∙ Whenever working on or near a bat-
tery, always wear suitable eye protec-
tors (for example, goggles or indus-
trial safety spectacles) and remove
rings, metal bands, or any other jew-
elry. Do not lean over the battery
when jump starting.
∙ Do not attempt to jump start a frozen battery. It could explode and cause
serious injury.
JUMP STARTING

WARNING
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.1. If the booster battery is in another ve- hicle, position the two vehicles to bring
their batteries near each other.
Do not allow the two vehicles to
touch. 2. Apply the parking brake. Move the shif t
lever to P (Park). Switch off all unneces-
sary electrical systems (lights, heater,
air conditioner, etc.).
3. Ensure the vent caps are level and tight.
4. Remove the fuse/fusible link box and connect jumper cables in the se-
quence illustrated (
A,B,C,D).
CAUTION
∙ Always connect positive () to posi-tive ( ) and negative () to body
ground (for example, strut mounting
bolt, engine lif t bracket, etc.) — not to
the battery.
∙ Make sure the jumper cables do not touch moving parts in the engine
compartment and that the cable
clamps do not contact any other
metal.
5. Start the engine of the booster vehicle and let it run for a few minutes.
6. Keep the engine speed of the booster vehicle at about 2,000 rpm, and start
the engine of the vehicle being jump
started.
CAUTION
Do not keep the starter motor engaged
for more than 10 seconds. If the engine
does not start right away, turn the key
off and wait 3 to 4 seconds before trying

6 Vehicle Care
Cleaning........................................6-2
Cleaning the engine ..........................6-2 Cleaning the exhaust
.........................6-2

In order to maintain the proper operation
of a diesel engine, it is important to take
proper care of it, which includes cleaning as
indicated.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup
keep the engine warmer than normal.
When washing:∙ Take care when using a power washer to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
∙ Do not spray a hot engine with cold wa- ter to avoid cracking the engine block or
other engine components.
∙ Spray an engine shampoo and/or degreaser on all parts that require
cleaning and pressure rinse clean.
∙ Never wash or rinse the engine while it is hot or running; water in the running
engine may cause internal damage.
∙ Never wash or rinse any control box electrical connections. ∙ Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the en-
gine.
CLEANING THE EXHAUST
The visible holesAin the exhaust system
are functional. The holes need to be kept
clear of mud/debris or foreign material to
maintain proper function of the exhaust
system. Clean and remove debris or for-
eign material if present as needed. Spray-
ing with a hose during regular washing of
vehicle should help keep holes clean and
clear of debris or foreign material.
LCE2252
CLEANING
6-2Vehicle Care

WARNING
∙ Failure to maintain the functionalholes in the exhaust system clean and
free of debris or foreign material may
result in the holes becoming blocked
or plugged. Do not modif y or remove
sections of the exhaust system that
contain these holes. Blocked or
plugged holesor
removal/modification of the system
could result in elevated exhaust gases
or exhaust gas temperatures which
may result in vehicle damage, per-
sonal injury or death.
∙ The normal operating temperature of the exhaust system is very high. Never
work around or attempt to repair any
part of the exhaust system until it has
cooled. Use special care when work-
ing around the diesel oxidation cata-
lytic converter and/or the diesel par-
ticulate filter (DPF). The diesel
oxidation catalytic converter and/or
the DPF heats up to a high tempera-
ture af ter only a short period of en-
gine operation and can stay hot even
af ter the engine is turned off. Failure
to follow these instructions may re-
sult in personal injury. ∙ When cleaning blocked or plugged
holes in the exhaust system, care
should be taken to minimize the
quantity of water entering the ex-
haust system. Excessive water that
enters the exhaust system could
cause damage requiring exhaust sys-
tem to be replaced.

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” in the “In case of
emergency ” section of the Titan Own-
er’s 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 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, 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 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 cause severe engine
damage. ∙ The life expectancy of the factory-fill
coolant is 45,000 miles (78,000 km) or
3 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 Titan Owner’s Manual.
∙ Use Nitrite Free Coolant or equivalent. The use of coolant containing Nitrites,
could cause severe engine damage.
ENGINE COOLING SYSTEM
Do-it-yourself7-3

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
45,000 miles (78,000 km) or 3 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 the Titan Own-
er’s Manual.
CAUTION
Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause
damage to the engine, transmission
and/or cooling system.
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.
Engine coolant must be disposed of prop-
erly. Check your local regulations.
