2019 NISSAN TITAN engine coolant

2. Turn thefan speed control dial to
the desired 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
speed control dial is turned to OFF, the air
conditioner is turned OFF, or the vehicle is
shut off. If a position other than the
front defrost air flow button is selected, the
A/C compressor will not turn off even if the
user had selected A/C off prior to entering
defrost. In
front defrost orfoot
defrost the indicator light on the A/C but-
ton will not turn on if the user had selected
A/C off. Turning off the air conditioning via
the A/C button is not allowed in this mode.
If the A/C button indicator was on when
entering this mode, and the A/C button is
selected in this mode, the A/C button indi-
cator will turn off, but the A/C compressor
will still be automatically enabled. This de-
humidifies the air which helps defog the
windshield. The
mode automatically
turns off, allowing outside air to be drawn
into the passenger compartment to fur-
ther improve the defogging 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

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.

∙ Make sure the area around the vehicle isclear.
∙ 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. 1. Apply the parking brake.
2. Move the shif t lever to P (Park) or N
(Neutral). P (Park) is recommended.
The starter is designed not to oper-
ate unless the shif t lever is in either P
(Park) or N (Neutral).
3. Push the ignition switch to the ON po- sition. Depress the brake pedal and
push the ignition switch to start the
engine.
To start the engine immediately, push
and release the ignition switch while
depressing the brake pedal with the
ignition switch in any position.
∙ If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator
pedal a little (approximately 1/3 to the
floor) and while holding, crank the en-
gine. Release the accelerator pedal
when the engine starts.
∙ If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch
to the ON position to start cranking
the engine. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition switch to the LOCK position. Af ter
cranking the engine, release the ac-
celerator pedal. Crank the engine
with your foot off the accelerator
pedal by depressing the brake pedal
and pushing the ignition switch to
start the engine. If the engine starts,
but fails to run, repeat the above pro-
cedure.
CAUTION
Do not operate the starter for more
than 15 seconds at a time. If the engine
does not start, push the ignition switch
to the OFF position and wait 10 seconds
before cranking again, otherwise the
starter could be damaged.
4. Warm-up
Allow the engine to idle for at least
30 seconds af ter starting. Do not race
the engine while warming it up. Drive at
a moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of 2 to 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.

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- 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, 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.
DRIVING THE VEHICLE
Starting and driving5-17

DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, 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.
Starting and driving5-69

∙ 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.
∙ Do not use the cruise control (if so equipped) on slippery roads.
∙ Snow can trap dangerous exhaust gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist
with cold temperature starting.
∙ Engine block heaters should be used when the outside temperature is 0°F
(-17°C) or lower.
∙ Engine block heaters run continuously while plugged into the correct voltage
electrical outlet.
WARNING
∙Do not use your engine block heater
with an ungrounded electrical system
or a 2-pronged adapter. You can be se-
riously injured by an electrical shock if
you use an ungrounded connection.
∙ Disconnect and properly store the en-gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury.
∙ Use a heavy-duty 3-wire, 3-pronged extension cord rated for at least 10 A.
Plug the extension cord into a Ground
Fault Interrupt (GFI) protected,
grounded 110-VAC outlet. Failure to
use the proper extension cord or a
grounded outlet can result in a fire or
electrical shock and cause serious
personal injury. To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged exten-
sion cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2–4 hours, de-
pending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
5-70Starting and driving

Do not attempt to start the engine by
pushing.
CAUTION
∙ Automatic transmission models can-not be push-started or tow-started.
Attempting to do so may cause trans-
mission damage.
∙ Three way catalyst equipped models should not be started by pushing
since the three way catalyst may be
damaged.
∙ Never try to start the vehicle by tow- ing it; when the engine starts, the for-
ward surge could cause the vehicle to
collide with the tow vehicle.
WARNING
∙ Do not continue to drive if your vehicleoverheats. Doing so could cause en-
gine damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant res-
ervoir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
∙ Do not open the hood if steam is com- ing out.
If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc. take the
following steps: 1. Move the vehicle safely off the road, ap- ply the parking brake and move the
shif t lever to P (Park).
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maxi-
mum hot and fan control to high
speed. 3. If engine overheating is caused by
climbing a long hill on a hot day, run the
engine at a fast idle (approximately
1,500 rpm) until the temperature gauge
indication returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. If
steam or coolant is escaping, turn off
the engine. Do not open the hood fur-
ther until no steam or coolant can be
seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling
fan is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking, the water pump belt is
missing or loose, or the cooling fan
does not run, stop the engine.
