lock NISSAN TITAN 2019 Owner´s Manual

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.

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.
Vehicle Care6-3

NOTE:
The factory fill oil may include a red dye
that is added for manufacturing quality
processes. The dye makes the oil appear
to be red. This is normal. The red dye will
be flushed from the engine af ter ap-
proximately 4–5 oil changes.1. Park the vehicle on a level surface and apply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature, then
turn it off.
3. Remove the oil filler cap
Aby turning it
counterclockwise.
4. Place a large drain pan under the drain plug
B.
5. Remove the drain plug
Bwith a
wrench by turning it counterclockwise
and completely drain the oil.
Remove and replace the engine oil fil-
ter at this time. For additional informa-
tion, refer to “Changing engine oil filter”
in this section.
∙ Waste oil must be disposed of prop-
erly.
∙ Check your local regulations.
WARNING
∙ Prolonged and repeated contact with
used engine oil may cause skin
cancer.
∙ Try to avoid direct skin contact with used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep used engine oil out of reach of children.
CAUTION
Be careful not to burn yourself. The en-
gine oil may be hot.
6. Clean and reinstall the drain plug. Se- curely tighten the drain plug with a
wrench. Do not use excessive force.
Drain plug tightening torque: 25 f t-lb (34 N·m) 7. Refill engine with recommended oil
through the oil filler opening, then install
the oil filler cap securely.
For additional information on drain
and refill capacity, refer to “Recom-
mended fluids/lubricants and capaci-
ties” in the “Capacities and specifica-
tions” section of this manual.
The drain and refill capacity depends
on the oil temperature and drain time.
Use these specifications for reference
only. Always use the dipstick to deter-
mine when the proper amount of oil is
in the engine.
8. Start the engine. Check for leakage around the drain plug and oil filter. Cor-
rect as required.
9. Turn the engine off and wait more than 10 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
NOTE:
For additional information on resetting
the oil control system, refer to “Resetting
the oil control system” in the “Instrument
panel” section of this manual.

CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface andapply the parking brake.
2. Turn the engine off.
3. Remove bolts
Aand skid plate. 4. Place a large drain pan under the oil
filter
B.
5. Loosen the oil filter with an oil filter wrench by turning it counterclockwise.
Then remove the oil filter by turning it
by hand.
CAUTION
Be careful not to burn yourself. The en-
gine oil may be hot.
6. Wipe the engine oil filter sealing surface with a clean rag.

AUTOMATIC REGENERATION
Automatic regeneration occurs when the
control module detects the exhaust filter
needs to be cleaned. This is a normal pro-
cess and will not typically require any op-
erator interaction.
If the automatic regeneration is not able to
clean the exhaust filter the vehicle informa-
tion display will display the following mes-
sages in order of severity:∙ Exhaust Filter Overloaded See Owner’s Manual for Drive Pattern
∙ Exhaust Filter Overloaded Engine Power Reduced See Owner’s Manual
∙ Exhaust Filter Overloaded Immediate Service Required
The instructions for these messages in the
“Meters and gauges” section of this manual
will inform the driver to modif y their driving
pattern to enable the automatic regenera-
tion process.

WARNING
To avoid the risk of personal injury, be
sure the ignition switch is in the OFF or
LOCK position before servicing drive
belt. The engine could rotate
unexpectedly.
1. Visually inspect the belt for signs of un- usual wear, cuts, fraying or looseness. If
the belt is in poor condition or is loose,
have it replaced. It is recommended
that you visit a NISSAN dealer for this
service.
2. Have the belt checked regularly for condition and tension in accordance
with the maintenance schedule found
in the Titan Owner’s Manual.
