engine overheat NISSAN TITAN 2021 Owner´s Manual

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (rpm). Do not rev
the engine into the red zone
O1.
CAUTION
When engine speed approaches the
red zone, reduce engine speed. Operat-
ing the engine in the red zone may
cause serious engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant
temperature. The engine coolant tempera-
ture is within the normal range
O1when
the gauge needle points within the zone
shown in the illustration.
The engine coolant temperature varies
with the outside air temperature and driv-
ing conditions.
CAUTION
If the gauge indicates coolant tem-
perature near the hot (H) end of the
normal range, reduce vehicle speed to
decrease temperature. If the gauge is
over the normal range, stop the vehicle
as soon as safely possible. If the engine
is overheated, continued operation of
the vehicle may seriously damage the
engine. For additional information, see
“If your vehicle overheats” (P. 6-12) for
immediate action required.

WARNING
• The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system
components.
• Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
CAUTION
• Do not use leaded gasoline. Deposits
from leaded gasoline will seriously
reduce the three-way catalyst's abil-
ity to help reduce exhaust pollutants.
• Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if no-
ticeable loss of performance or other
unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended that
you visit a NISSAN dealer for this
service. •
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
• Do not race the engine while warm-
ing it up.
• Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as pos-
sible, and inflate them to the proper pres- sure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the malfunc-
tion indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions
may occur for a variety of reasons, includ-
ing the installation of replacement or alter-
nate tires or wheels on the vehicle that

Please observe the following precautions:
WARNING
• Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle
should be seated with their seat belt
fastened. This will keep you and your
passengers in position when driving
over rough terrain.
• Do not drive across steep slopes. In-
stead drive either straight up or
straight down the slopes. Off-road
vehicles can tip over sideways much
more easily than they can forward or
backward.
• Many hills are too steep for any ve-
hicle. If you drive up them, you may
stall. If you drive down them, you may
not be able to control your speed. If
you drive across them, you may roll
over.
• Do not shif t gears while driving on
downhill grades as this could cause
loss of control of the vehicle.
• Stay alert when driving to the top of a
hill. At the top there could be a drop-
off or other hazard that could cause
an accident. •
If your engine stalls or you cannot
make it to the top of a steep hill,
never attempt to turn around. Your
vehicle could tip or roll over. Always
back straight down in R (Reverse)
gear and apply brakes to control your
speed.
• Heavy braking going down a hill
could cause your brakes to overheat
and fade, resulting in loss of control
and an accident. Apply brakes lightly
and use a low gear to control your
speed.
• Unsecured cargo can be thrown
around when driving over rough ter-
rain. Properly secure all cargo so it
will not be thrown forward and cause
injury to you or your passengers.
• Secure heavy loads in the cargo area
as far forward and as low as possible.
Do not equip the vehicle with tires
larger than specified in this manual.
This could cause your vehicle to roll
over.
• Do not grip the inside or spokes of
the steering wheel when driving off-
road. The steering wheel could move
suddenly and injure your hands. In-
stead drive with your fingers and
thumbs on the outside of the rim. •
Before operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
• Lower your speed when encounter-
ing strong crosswinds. With a higher
center of gravity, your NISSAN is more
affected by strong side winds. Slower
speeds ensure better vehicle control.
• Do not drive beyond the perfor-
mance capability of the tires, even
with 4WD engaged.
• For 4WD equipped vehicles, do not
attempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or per-
sonal injury.

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. 2-20).
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.
DRIVING THE VEHICLE
5-18Starting and driving

3. To help prevent the vehicle from rollinginto traffic when parked on an incline, it
is a good practice to turn the wheels as
illustrated.
• HEADED DOWNHILL WITH CURB
OA:
Turn the wheels into the curb and
move the vehicle forward until the
curb side wheel gently touches the
curb.
• HEADED UPHILL WITH CURB
OB:
Turn the wheels away from the curb
and move the vehicle back until the
curb side wheel gently touches the
curb.
• HEADED UPHILL OR DOWNHILL, NO
CURB
OC:
Turn the wheels toward the side of the
road so the vehicle will move away
from the center of the road if it moves.
4. Place the ignition switch in the LOCK position. The power assisted steering uses a hy-
draulic pump, driven by the engine, to as-
sist steering.
If the engine stops or the drive belt breaks,
you will still have control of the vehicle.
However, much greater steering effort is
needed, especially in sharp turns and at
low speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate. The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshif t to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.
WARNING
• While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshif ting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an
accident.
• If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
