cooling NISSAN TITAN 2020 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 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, 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
reversing. This could cause an acci-
dent or damage the transmission.
DRIVING THE VEHICLE
5-18Starting and driving

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to ob-
tain maximum engine performance
and ensure the future reliability and
economy of your new vehicle. Failure to
follow these recommendations may
result in shortened engine life and re-
duced engine performance.
• Avoid driving for long periods at constant speed, either fast or slow, and do not run
the engine over 4,000 rpm.
• Do not accelerate at full throttle in any gear.
• Avoid quick starts.
• Avoid hard braking as much as possible.
• Do not tow a trailer for the first 500 miles (805 kilometers). Your engine, axle or
other parts could be damaged. Follow these easy-to-use Fuel Efficient
Driving Tips to help you achieve the most
fuel economy from your vehicle.
1.
Use Smooth Accelerator and Brake
Pedal Application
• Avoid rapid starts and stops.
• Use smooth, gentle accelerator and brake application whenever possible.
• Maintain constant speed while com- muting and coast whenever possible.
2. Maintain Constant Speed
• Look ahead to try and anticipate and minimize stops.
• Synchronizing your speed with traffic lights allows you to reduce your num-
ber of stops.
• Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency.
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
• Below 40 mph (64 km/h), it is more efficient to open windows to cool the
vehicle due to reduced engine load.
• Above 40 mph (64 km/h), it is more efficient to use A/C to cool the vehicle
due to increased aerodynamic drag. • Recirculating the cool air in the cabin
when the A/C is on reduces cooling
load.
4. Drive at Economical Speeds and
Distances
• Observing the speed limit and not ex- ceeding 60 mph (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
• Maintaining a safe following distance behind other vehicles reduces unnec-
essary braking.
• Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
• Select a gear range suitable to road conditions.
5. Use Cruise Control
• Using cruise control during highway driving helps maintain a steady speed.
• Cruise control is particularly effective in providing fuel savings when driving
on flat terrains.
6. Plan for the Shortest Route
• Utilize a map or navigation system to determine the best route to save time.

SYSTEM MAINTENANCE
The sonar sensorsO1are located on the
front and rear bumpers. Always keep the
area near the sonar sensors clean.
The sonar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the sonar sensors.
Check for and remove objects obstructing
the area around the sonar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you consult a NISSAN dealer if the area
around the sonar sensors is damaged due
to a collision.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry key fob.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
refer to “Engine cooling system” in the “Do-
it-yourself ” section of this manual.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, refer to “Battery”
in the “Do-it-yourself ” section of this
manual.
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

3. If engine overheating is caused byclimbing a long hill on a hot day, run the
engine at a fast idle (approximately 1,500
rpm) until the temperature gauge indi-
cation returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the ra-
diator before opening the hood. If steam
or coolant is escaping, turn off the en-
gine. Do not open the hood further 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 radia-
tor should not leak water. If coolant is
leaking, the water pump belt is missing
or loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into con-
tact with, or get caught in, engine belts
or the engine cooling fan. The engine
cooling fan can start at any time.
7. Af ter the engine cools down, check the coolant level in the engine coolant reser-
voir tank with the engine running. Add
coolant to the engine coolant reservoir
tank if necessary. It is recommended
that you visit a NISSAN dealer for this
service. When towing your vehicle, all jurisdictional
and local regulations for towing must be
followed. Incorrect towing equipment
could damage your vehicle. Towing in-
structions are available from a NISSAN
dealer. Local service operators are gener-
ally familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage
to your vehicle, NISSAN recommends hav-
ing a service operator tow your vehicle. It is
advisable to have the service operator
carefully read the following precautions:
WARNING
• Never ride in a vehicle that is being
towed.
• Never get under your vehicle af ter it
has been lif ted by a tow truck.
• If your vehicle has front recovery
hooks as original factory equipment,

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
• Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park)
• Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing any parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
• It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
• Always wear eye protection when-
ever you work on your vehicle.
• The automatic engine cooling fan (if
so equipped) may come on at any
time without warning, even if the ig-
nition switch is in the OFF position and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before work-
ing near the fan.
• If you must run the engine in an en-
closed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
• Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
• Because the fuel lines are under high
pressure even when the engine is off,
it is recommended that you visit a
NISSAN dealer for service of the fuel
filter or fuel lines.
CAUTION
• Do not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
• Avoid contact with used engine oil
and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can damage the environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
• Never leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.
NOTE:
If the battery is dead the transmission
will not manually shif t to other positions.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner's Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and

about any servicing, it is recommended
that you have it done by a NISSAN dealer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round antifreeze and coolant protec-
tion. The antifreeze solution contains rust
and corrosion inhibitors. Additional engine
cooling system additives are not neces-
sary.
WARNING
• Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator
cool down. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator. For additional
information on precautions, refer to
“If your vehicle overheats” found in
the “In case of emergency ” section of
this manual.
• The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, it is recommended
that you use only a Genuine NISSAN
radiator cap.
CAUTION
• Never use any cooling system addi-
tives such as radiator sealer. Addi-
tives may clog the cooling system
and cause damage to the engine,
transmission and/or cooling system.
• When adding or replacing coolant, it
is recommended that you use only
Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-
diluted to provide antifreeze protec-
tion to -34° F (-37° C). If additional
freeze protection is needed due to
weather where you operate your ve-
hicle, add Genuine NISSAN Long Life
Antifreeze/Coolant (blue) concen-
trate following the directions on the
container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s in-
structions to maintain minimum an-
tifreeze protection to -34° F (-37° C).
The use of other types of coolant so-
lutions other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
or equivalent may damage the en-
gine cooling system. •
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km)
or 7 years. Mixing any other type of
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
(or equivalent coolant), including
Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the
use of non-distilled water may re-
duce the life expectancy of the
factory-fill coolant. For additional in-
formation, refer to the "Maintenance
and schedules" section of this
manual.
ENGINE COOLING SYSTEM
Do-it-yourself8-5

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
OB, add coolant
to the MAX level
OA. If the reservoir is empty,
check the coolant level in the radiator
when the engine is cold. If there is insuffi-
cient coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to the MAX
level
OA. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water may reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to “Maintenance
and schedules” section of this manual.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended that you visit a NISSAN dealer
for this service. For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment check locations” in this
section.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
• To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
• Never remove the radiator or engine
coolant reservoir cap when the en-
gine is hot. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator.
• Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand
cleaner as soon as possible.
• Keep coolant out of the reach of chil-
dren and pets.LDI3295
