2018 NISSAN TITAN engine coolant

Maintenance
The maintenance menu allows the user to
set reminders for various vehicle mainte-
nance items.
WARNING
The tire replacement indicator is not a
substitute for regular tire checks, in-
cluding tire pressure checks. For addi-
tional information, refer to “Changing
wheels and tires” in the “Do-it-yourself ”
section of this manual. Many factors in-
cluding tire inflation, alignment, driving
habits and road conditions affect tire
wear and when tires should be re-
placed. Setting the tire replacement in-
dicator for a certain driving distancedoes not mean your tires will last that
long. Use the tire replacement indicator
as a guide only and always perform
regular tire checks. Failure to perform
regular tire checks, including tire pres-
sure checks could result in tire failure.
Serious vehicle damage could occur
and may lead to a collision, which could
result in serious personal injury or
death.

2-38Instruments and controls

Dehumidified defogging
This mode is used to defog the windows
and dehumidif y the air.1. Press the
front defroster button.
2. Turn the
fan control dial to the de-
sired position.
When the
orpositions are se-
lected, the air conditioner automatically
turns on if the outside temperature is more
than 36°F (2°C). The air conditioning system
will continue to operate until the
fan
control dial is turned to OFF, the air condi-
tioner is turned OFF, or the vehicle is shut
off, even if a position other than the
air flow control button is selected. Under
this condition, the indicator light on the A/C
button indicator will not turn off if the user
had selected A/C off. Turning off the air
conditioning via the A/C button is not al-
lowed in this mode. If the A/C button indi-
cator was on when entering this mode, and
the A/C button is selected in this mode, the
A/C button indicator will turn off, but the
A/C compressor will still be automatically
enabled. This dehumidifies the air which
helps defog the windshield. The
mode automatically turns off, allowing out-
side air to be drawn into the passenger compartment to further improve the de-
fogging performance.
3. Turn the temperature control dial to the desired position.
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 com-
partment. Then, close the windows.
This allows the air conditioner to cool
the interior more quickly.
∙ The air conditioning system should
be operated for approximately
10 minutes at least once a month.
This helps prevent 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, refer to “If your vehicle
overheats” in the “In case of emer-
gency ” section of this manual.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,
refer to “Heater and air conditioner
(manual)” in this section. The air recircula-
tion (
) button should always be in
the OFF position for heating and defrost-
ing.

For additional information, refer to “Rear
window and / or outside mirror (if so
equipped) defroster switch” in the “Instru-
ments and controls” section of this manual.
OPERATING TIPS
The sunload sensor (if so equipped)1, lo-
cated on the top center of the instrument
panel, helps the system maintain a con-
stant temperature. Do not put anything on
or around this sensor. ∙ When the climate system is in auto-
matic operation and the engine coolant
temperature and outside air tempera-
ture are low, the air flow outlet may de-
fault to defroster mode for a maximum
of 2 minutes 30 seconds. This is not a
malfunction. Af ter the engine coolant
temperature warms up, the air flow out-
let will return to foot mode and opera-
tion will continue normally.
∙ When the outside and interior cabin temperatures are moderate to high, the
intake setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may oc-
cur when previous climate setting was
system off. This is not a malfunction.
Af ter the initial warm air is expelled, the
intake will return to automatic control,
air flow outlet will return to previous set-
tings, and operation will continue nor-
mally. To exit, press any climate control
button.
∙ Keep the windows closed while the air conditioner is in operation.

Af ter step 3 is performed, when the
ignition switch is pushed without de-
pressing the brake pedal, the ignition
switch position will change to the ON
position.
4. Push the ignition switch while depress- ing the brake pedal within 10 seconds
af ter the chime sounds. The engine will
start.
NOTE: ∙ When the ignition switch is pushed to
the ON position or the engine is
started by the above procedure, the
Intelligent Key battery discharge in-
dicator appears in the vehicle infor-
mation display even when the Intelli-
gent Key is inside the vehicle. This is
not a malfunction. To turn off the In-
telligent Key battery discharge indi-
cator, touch the ignition switch with
the Intelligent Key again.
∙ If the Intelligent Key battery dis-
charge indicator appears, replace the
battery as soon as possible. For addi-
tional information, refer to “Battery
replacement” in the “Do-it-yourself ”
section of this manual.NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedures:
1. Leave the ignition switch in the ON po- sition for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the in-
terference) separate from the regis-
tered key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. ∙ Make sure the area around the vehicle is
clear.
∙ Check fluid levels such as engine oil, coolant, brake fluid, Diesel Exhaust Fluid
(Diesel only) and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appear- ance and condition. Also check tires for
proper inflation.
∙ Check that all doors are closed.
∙ Position seat and adjust head restraints/headrests.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passen- gers to do likewise.
∙ Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual.
BEFORE STARTING THE ENGINE
5-14Starting and driving

REMOTE ENGINE START (if so
equipped)
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t
lever can be moved from the P (Park) posi-
tion. To place the ignition switch in the ON
position, follow these steps:1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Push the ignition switch once to the ON position.
For additional information, refer to “NISSAN
Intelligent Key®” in the “Pre-driving checks
and adjustments” section of this manual. For additional information on starting your
diesel engine, refer to your Titan Diesel
Owner’s Manual.
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 gauge will 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-
STARTING THE ENGINE (diesel only) DRIVING THE VEHICLE
5-16Starting and driving

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. Ifonly 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, refer to “Malfunc-
tion Indicator Light (MIL)” in the “Instru-
ments and controls” section of this manual.
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, refer to “If your
vehicle overheats” in the “In case of
emergency ” section of this manual.
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 re-
versing. This could cause an accident
or damage the transmission. ∙ Except in an emergency, do not shif t
to the N (Neutral) position while driv-
ing. Coasting with the transmission in
the N (Neutral) position may cause se-
rious damage to the transmission.
∙ Do not downshif t abruptly on slippery roads. This may cause a loss of
control.
CAUTION
To avoid possible damage to your ve-
hicle, when stopping the vehicle on an
uphill grade, do not hold the vehicle by
depressing the accelerator pedal. The
foot brake should be used for this
purpose
The A/T in your vehicle is electronically con-
trolled to produce maximum power and
smooth operation.
The recommended operating procedures
for this transmission are shown on the fol-
lowing pages. Follow these procedures for
maximum vehicle performance and driv-
ing enjoyment.

DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
anti-freeze, drain the cooling system, in-
cluding the engine block. Refill before oper-
ating the vehicle. For additional informa-
tion, refer to “Changing engine coolant” in
the “Do-it-yourself ” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance
of these tires will be substantially re-
duced in snowy and icy conditions. If
you operate your vehicle on snowy or
icy roads, NISSAN recommends the use
of MUD & SNOW or ALL SEASON TIRES
on all four wheels. It is recommended
that you visit a NISSAN dealer for the tire
type, size, speed rating and availability
information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires. Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used. For additional information, refer to “Tire chains” in the
“Do-it-yourself ” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
∙ A scraper and stiff-bristled brush to re- move ice and snow from the windows
and wiper blades.
∙ A sturdy, flat board to be placed under the jack to give it firm support.
∙ A shovel to dig the vehicle out of snow- drif ts.
∙ Extra washer fluid to refill the windshield-washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
∙ Wet ice (32°F, 0°C and freezing rain),very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” un-
der these conditions. Try to avoid driv-
ing on wet ice until the road is salted
or sanded.
∙ Whatever the condition, drive with caution. Accelerate and slow down
with care. If accelerating or down-
shif ting too fast, the drive wheels will
lose even more traction.
∙ Allow more stopping distance under these conditions. Braking should be
started sooner than on dry pavement.
∙ Allow greater following distances on slippery roads.
∙ Watch for slippery spots (glare ice). These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steering
maneuvers.
