2019 NISSAN TITAN warning light

will be reduced. It is recommended that
you visit a NISSAN dealer or qualified tech-
nician immediately. For additional informa-
tion, refer to “Diesel Particulate Filter (DPF)”
in the “Do-it-yourself ” section of this
manual.
Engine Warming Keep Foot on Brake
This message appears during cold start
conditions when:∙ Brake pedal is depressed
∙ Push-button start button has been pressed
∙ Coolant temperature is below thresh- old
Keep foot on the brake until the engine
starts, which can take up to approximately
4 seconds. For additional information, refer
to “Starting the diesel engine” in the “Start-
ing and stopping the engine” section of this
manual. Engine Shutdown: Stop Safely
This message appears 30 seconds before
the vehicle is shutdown due to an above
normal operating exhaust temperature.
The Malfunction Indicator Light (MIL) and
malfunction warning light (red) will illumi-
nate. It is recommended that you visit a
NISSAN dealer or other qualified technician
immediately.
Engine Power Reduced
This message appears when the engine is
not operating under normal conditions. For
additional information, refer to “Engine Pro-
tection Mode” in the “Introduction” section
of this manual.
Service Air Filter
This warning appears when the air filter
needs to be serviced. For additional infor-
mation, refer to “Air cleaner” in the ”Mainte-
nance” section of the Titan Diesel Owner’s
Manual.Engine Oil Service due XX
This message is a count down of mileage
until the next engine oil service is due. Mile-
age until next required engine oil service
will be displayed by the vehicle information
display and will decrease at a higher rate as
vehicle operation severity (high duty cycle)
increases.
Coolant Level Low: See Owner’s Manual
This warning appears when the coolant
level in the reservoir is below the MIN level.
For additional information, refer to “Engine
Cooling System” in this manual.
Low Fuel Pressure: See Owner’s Manual
This message appears when low fuel pres-
sure has been detected downstream of
the stage 2 fuel filter. This message can
indicate the fuel filters are restricted and
require replacement. It is recommended
that you have the system checked by a
NISSAN dealer or other qualified technician.

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
again.
7. Af ter starting the engine, carefully dis- connect the negative cable and then
the positive cable.

In Case of Emergency5-3

WARNING
∙ Stay clear from the exhaust outlet andexhaust gases. These can cause burns
or personal injury.
∙ To avoid the risk of personal injury or fire, do not park the vehicle over flam-
mable materials such as dry grass,
waste paper or rags, as hot vehicle
components may ignite them.
CAUTION
To maintain maximum Diesel Particu-
late Filter (DPF) performance, follow
these precautions:
∙ Use ultra low-sulfur fuel.
∙ Use an engine oil specified by NISSAN.For additional information, refer to
“Recommended fluids/lubricants and
capacities” in the “Capacities and
specifications” section of this manual.
If an engine oil not specified by
NISSAN is used, it could cause DPF
malfunction or reduced fuel
efficiency. ∙ Do not modif y the DPF, muffler or ex-
haust pipe. Otherwise it could affect
the DPF performance and cause a
malfunction.
∙ Do not kick or hit the DPF. The DPF has a built-in catalyst system in the muf-
fler. Such an impact could cause DPF
damage.
The DPF reduces the amount of materials
that affect the environment by collecting
particulate matter included in exhaust
gases. Normally, particulate matter accu-
mulated in the DPF is automatically burned
and converted to harmless substances
during driving. However, particulate matter
collected in the DPF cannot be burned un-
der the following conditions: ∙ When vehicle speed remains below 5 mph (8 km/h) for a long period of time.
∙ When the engine is frequently stopped and restarted within 10 minutes.
∙ When the vehicle is frequently used for short journeys of 10 minutes or less.
∙ When the engine is frequently stopped before it has warmed up. In these cases, it becomes difficult to burn
particulate matter that has accumulated
in the DPF. As a result, the DPF warning light
will illuminate/blink and one of the follow-
ing messages will display on the vehicle
information display (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
For additional information, refer to “Meters
and gauges" in the “Instrument panel” sec-
tion of this manual.
CAUTION
∙ If the vehicle continues to be driven with the DPF warning light illumi-
nated and without doing the regen-
eration process, the fail-safe will limit
the engine revolutions and/or torque.
In this case, it is recommended to con-
tact a NISSAN dealer to have the Ser-
vice Regeneration procedure
performed.
