2017 NISSAN TITAN engine

WARNING
●Do not use starting fluid, such as ether,
in the air intake system. Use of such
fluid could cause engine damage
and/or personal injury.
● Do not add gasoline, alcohol or kero-
sene to diesel fuel.
CAUTION
● Read all starting instructions carefully
prior to starting your vehicle.
● When starting the engine in extremely
cold temperatures, it is recommended
to allow the engine to idle for several
minutes before driving the vehicle.
● The use of the factory engine block
heater (if so equipped) will assist in
starting the engine in extreme cold am-
bient temperatures. For additional in-
formation, refer to the “Starting and
driving” section of your owner’s manual. Engine warming
This message may display during cold starting
conditions. It is a reminder that during cold start-
ing conditions the engine may not crank immedi-
ately after pressing the ignition switch, and could
take up to approximately 4 seconds to crank. The
brake pedal must be depressed during this wait
period.
1. Verify the shift lever is in the P (Park) or N (Neutral) position. P (Park) is recommended.
The shift lever cannot be moved out of
P (Park) and into any of the other gear
positions if the ignition switch is in the
OFF position. The starter is designed not to operate if
the shift lever is in any of the driving
positions.
2. There are two ways to start your diesel en- gine.
● Push the ignition switch to the ON posi-
tion, wait up to 4 seconds for the glow
plug to warm up. Depress the brake pedal
and push the ignition switch to start the
engine.
or
● Depress the brake pedal and push the
ignition switch to start the engine. Keep
the brake pedal depressed until the glow
plug warms up. This could take up to
4 seconds. Vehicle will start.
The starter is designed to not engage
until the glow plugs have had sufficient
time to warm up. During cold tempera-
tures this could take up to 4 seconds.
CAUTION
If the engine does not start, turn the igni-
tion off and wait 10 seconds before crank-
ing again, otherwise the starter could be
damaged.

STARTING THE DIESEL ENGINE
3-2Starting and Stopping the Engine

3. Allow the engine to idle for at least 30 sec-onds after starting. Do not race the engine
while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather.
In cold weather, keep the engine running for
a minimum of 2–3 minutes before shutting it
off. Starting and stopping the engine over a
short period of time may make the vehicle
more difficult to start.
SWITCHING ENGINE OFF
Push the ignition to the off position.
To prolong the engine life (especially after ex-
tended high speed, high ambient temperature, or
during heavy load operation, such as trailering) , it
is recommended that a hot engine be idled for
3–5 minutes before shutting down. This allows
the turbocharged engine to cool down.
ENGINE BREAK-IN
RECOMMENDATIONS
● Warm up the engine before operating it un-
der load.
● Do not operate the engine at idle for ex-
tended periods. ●
Prevent engine lugging by selecting the ap-
propriate transmission gear.
● Monitor the vehicle oil pressure and tem-
perature gauges.
● Check fluid levels frequently (oil and cool-
ant) .
● Vary the throttle position at highway speeds
when carrying weight or towing.
NOTE:
Extended light or no load operation will
extend the time before the engine reaches
its full efficiency. If the engine is operated
in this manner reduced fuel economy and
power may be observed.
The aforementioned procedure should be ob-
served for the first 6,000 miles. The engine run-in
is improved by operating the vehicle under load.
REMOTE START (if so equipped)
CAUTION
Laws in some jurisdictions prohibit use of
remote start. Vehicles started with the remote start require the
ignition switch to be placed in the ON position
before the shift lever can be moved from the P
(Park) position. To place the ignition switch to the
ON position, follow these steps:
1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Press the ignition switch once to the ON position.
For additional information, refer to “NISSAN In-
telligent Key®” in the “Pre-driving checks and
adjustments” section of your owner’s manual.
ENGINE BLOCK HEATER (if so
equipped)
The power cable to operate the heater is avail-
able as a service part from an authorized NISSAN
dealer.
For additional information, refer to “Engine block
heater” in the “Starting and Driving” section of
your owner’s manual.

DIESEL FUEL-FILLER CAP
WARNING
●Diesel fuel is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling. ●
Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
● Use only an original equipment type
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause
the
Malfunction Indicator Light
(MIL) to come on.
● Do not use starting fluids with this en-
gine. It is equipped with an intake air
heater. The use of starting fluid could
cause an explosion, fire, personal in-
jury, system or engine damage.
● Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable fuel
containers:
– Always place the container on the ground when filling. – Do not use electronic devices when
filling.
– Keep the pump nozzle in contact with the container while you are fill-
ing it.
– Use only approved portable fuel con- tainers for flammable liquid.
CAUTION
●For additional information, refer to the
“Malfunction Indicator Light (MIL)” in
the “Instruments and Controls” section
of the Titan Owner’s Manual.

4-4Fuel and Refueling

To start your engine with a booster battery, the
instructions and precautions below must be fol-
lowed.
WARNING
●If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also
damage your vehicle.
● Explosive hydrogen gas is always pres-
ent 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 cor-
rosive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted 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 battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
● Do not attempt to jump start a frozen
battery. It could explode and cause se-
rious injury.
