2023 NISSAN TITAN heating

Thebutton will be on the NISSAN
Intelligent Key® if the vehicle has Remote
Engine Start. This feature allows the engine
to start from outside the vehicle.
Vehicles with an automatic climate control
system (if so equipped) may default to ei-
ther a heating or cooling mode depending
on outside and cabin temperatures. For
additional information, see “Remote Engine
Start with Intelligent Climate Control”
(P. 4-39).
Vehicles with a manual climate control sys-
tem (if so equipped) will default to the last
used heating or cooling mode. Laws in some local communities may re-
strict or prohibit the use of Remote Engine
Start, or the amount of time a parked ve-
hicle engine may idle. For example, some
laws require a person using Remote Engine
Start to have the vehicle in view or may
restrict idling time except in freezing tem-
peratures. Check local regulations for any
requirements.
Other conditions may affect the function of
the Remote Engine Start feature. For addi-
tional information, see “Conditions the Re-
mote Engine Start will not work” (P. 3-24).
Other conditions can affect the perfor-
mance of the Intelligent Key transmitter.
For additional information, see “NISSAN In-
telligent Key® system” (P. 3-9).

WARNING
• To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
• Do not use Remote Engine Start in
closed spaces such as a garage. Do
not breathe exhaust gases; they con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconscious-
ness or death.

Operating tips
• Keep the windows closed while the airconditioner is in operation.
• Af ter parking in the sun, drive for 2 or 3 minutes with the windows open to vent
hot air from the passenger compart-
ment. Then, close the windows. This al-
lows the air conditioner to cool the inte-
rior more quickly.
• The air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
• A visible mist may be seen coming from the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
• If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. For additional
information, see “If your vehicle over-
heats” (P. 6-12).
AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. For addi-
tional information on heating and cooling,
see “Heater and air conditioner (manual)”
(P. 4-28). The air recirculation (
) but-
ton should always be in the OFF position
for heating and defrosting.

Remote Engine Start with
Intelligent Climate Control (if so
equipped)
Vehicles equipped with automatic climate
controls and Remote Engine Start function
may go into automatic heating or cooling
mode when Remote Engine Start is acti-
vated depending on outside and cabin
temperatures. During this period, the cli-
mate control display and buttons will be
inoperable until the ignition switch is
placed in the ON position. In Remote En-
gine Start defrosting mode, the rear win-
dow defroster (if so equipped), heated
seats (if so equipped) and heated steering
wheel (if so equipped) may be activated
automatically.
Voice Recognition logic (if so
equipped)
When the climate control system is on, the
front fan speeds may be automatically
lowered so that commands are more eas-
ily recognized. Fan speed can be adjusted
using the fan speed
decrease andincrease buttons, if desired.
MANUAL OPERATION

ENGINE PROTECTION MODE
The engine has an engine protection mode
to reduce the chance of damage if the
coolant temperature becomes too high
(for example, when climbing steep grades
in high temperatures with heavy loads,
such as when towing a trailer). When the
engine temperature reaches a certain
level:
• The engine coolant temperature gaugewill move toward the H position.
• Engine power may be reduced.
• The air conditioning cooling function may be automatically turned off for a short
time (the blower will continue to operate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator
pedal, but the vehicle may not accelerate at
the desired speed. The transmission will
downshif t or upshif t as it reaches pre-
scribed shif t points. You can also shif t
manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accel-
erator pedal, and the air conditioning cool-
ing function will automatically be turned
back on. The Malfunction Indicator Light (MIL) may
also come on if the engine coolant tem-
perature is not reduced or the air condi-
tioning cooling function does not turn back
on. If
only it remains on, you do not need to
have your vehicle towed, but have it in-
spected soon. It is recommended that you
visit a NISSAN dealer for this service. For
additional information, see “Malfunction In-
dicator Light (MIL)” (P. 2-22).
WARNING
Overheating can result in reduced en-
gine power and vehicle speed. The re-
duced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful
when driving. If the vehicle cannot
maintain a safe driving speed, pull to
the side of the road in a safe area. Allow
the engine to cool and return to normal
operation. For additional information,
see “If your vehicle overheats” (P. 6-12).
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.
AUTOMATIC TRANSMISSION (A/T)
WARNING
• Do not depress the accelerator pedal
while shif ting from P (Park) or N (Neu-
tral) to R (Reverse) or D (Drive). Always
depress the brake pedal until shif ting
is completed. Failure to do so could
cause you to lose control and have an
accident.
• Cold engine idle speed is high, so use
caution when shif ting into a forward
or reverse gear before the engine has
warmed up.
• Never shif t to either the P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is
reversing. This could cause an acci-
dent or damage the transmission.
