2021 NISSAN TITAN fuel consumption

WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they
contain colorless and odorless car-
bon monoxide. Carbon monoxide is
dangerous. It can cause uncon-
sciousness or death. •
If you suspect that exhaust fumes
are entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
• Do not run the engine in closed
spaces such as a garage.
• Do not park the vehicle with the en-
gine running for any extended length
of time.
• Keep the rear vent windows, lif t-
gates, doors and trunk lids (if so
equipped) closed while driving, oth-
erwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with one of
these open, follow these precau-
tions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the lif tgate or the
body, follow the manufacturer's rec-
ommendation to prevent carbon
monoxide entry into the vehicle. •
The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
NOTE:
If the vehicle engine experiences exces-
sive fuel consumption or produces ex-
cessive smoke it is recommended that
you visit a NISSAN dealer for service.
THREE-WAY CATALYST (if so
equipped)
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-4Starting and driving

• Keep your engine tuned up.
• Follow the recommended scheduledmaintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire
wear and lowers fuel economy.
• Keep the wheels in correct alignment. Im- proper alignment increases tire wear and
lowers fuel economy.
• For vehicles equipped with
, use 4H
or 4L position only when necessary.
4-Wheel Drive operation lowers fuel
economy.
• Use the recommended viscosity engine oil. For additional information, see “Engine
oil and oil filter recommendations”
(P. 10-7).
WARNING
• 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.
• Do not attempt to test a 4WD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamom-
eters used by some states for emis-
sions testing) or similar equipment
even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that
your vehicle is equipped with 4WD
before it is placed on a dynamom-
eter. Using the wrong test equipment
may result in drivetrain damage or
unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.CAUTION
• Do not drive the vehicle in the 4H or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces in
4H or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD vehicle information dis-
play warning message turns on
when you are driving on dry hard sur-
face roads:
– In the 4H position, shif t the 4WD
shif t switch to 2WD.
– In the 4LO position, stop the ve-
hicle, move the shif t lever to the N
(Neutral) position with the brake
pedal depressed, and shif t the
4WD shif t switch to 2WD.
• If the vehicle information display
warning message is still on af ter the
above operation, have your vehicle
checked as soon as possible. It is rec-
ommended that you visit a NISSAN
dealer for this service.
INCREASING FUEL ECONOMY USING 4–WHEEL DRIVE (4WD) (if so
equipped)
Starting and driving5-105

The transfer case 4WD shif t switch is used
to select either 2WD or 4WD depending on
the driving conditions. There are three
types of drive modes available: 2WD, 4H and
4LO.
The 4WD shif t switch electronically controls
the transfer case operation. Rotate the
switch to move between each mode: 2WD,
4H and 4LO.
To change into or out of 4LO, the vehicle
MUST be stationary, move the shif t lever
to N (Neutral), and depress the brake
pedal. The switch must be pushed and
turned to select 4LO.
WARNING
• When parking, apply the parking
brake before stopping the engine
and make sure that the 4WD shif t
indicator is on and the Automatic
Transmission Park (ATP) warning
light goes off. Otherwise, the vehicle
could unexpectedly move even if the
A/T is in the P (Park) position. •
The 4LO indicator must stop blinking
and remain illuminated or turn off
before shif ting the transmission into
gear. If the shif t lever is shif ted from
the N (Neutral) position to any other
gear when the 4LO indicator is blink-
ing, the vehicle may move
unexpectedly.
CAUTION
• Never shif t the 4WD shif t switch be-
tween 4LO and 4H while driving.
•
The 4H position provides greater trac-
tion. Avoid excessive speed, as it will
cause increased fuel consumption
and higher oil temperatures, and
could damage drivetrain components.
Speeds over 62 mph (100 km/h) in 4H
is not recommended.
• The 4LO position provides maximum
power and traction. Avoid raising ve-
hicle speed excessively, as the maxi-
mum speed is approximately 31 mph
(50 km/h).
•
When driving straight, shif t the 4WD
shif t switch to the 2WD or 4H position.
Do not move the 4WD shif t switch
when making a turn or reversing.
• Do not shif t the 4WD shif t switch (be-
tween 2WD and 4H) while driving on
steep downhill grades. Use the en-
gine brake and low A/T gears (M1 or
M2) for engine braking.
• Do not operate the 4WD shif t switch
(between 2WD and 4H) with the rear
wheels spinning.
• Do not drive on dry hard surface
roads in the 4H or 4LO position. Driv-
ing on dry hard surfaces in 4H or 4LO
may cause unnecessary noise and
tire wear. NISSAN recommends driv-
ing in the 2WD position under these
conditions.
• The 4WD transfer case may not be
shif ted between 4H and 4LO at low
ambient temperatures and the
transfer 4LO position indicator may
blink even when the 4WD shif t switch
is shif ted. Af ter driving for a while
you can change the 4WD transfer
case between 4H and 4LO.

Warning message
Warning messageWarning message comes on when:
Vehicle information display
4WD Error: See Owner’s Manual There is a malfunction in the 4–Wheel Drive system
FRT & RR tire size difference: See Owner’s Manual The difference in wheel rotation is large
CAUTION
• If the warning message comes on
during operation or rapidly af ter
stopping the vehicle for a while, have
your vehicle checked as soon as pos-
sible. It is recommended that you
visit a NISSAN dealer for this service.
• Shif ting between 4H and 4LO is not
recommended when the 4WD warn-
ing message turns on.
• When the warning message comes
on, the 2WD mode may be engaged
even if the 4WD shif t switch is in 4H.
Be especially careful when driving. If
corresponding parts are malfunc-
tioning, the 4WD mode will not be en-
gaged even if the 4WD shif t switch is
shif ted.
• Do not drive the vehicle in the 4H or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces
in 4H or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD warning message turns on
when you are driving on dry hard sur-
face roads:
– In the 4H position, shif t the 4WD
shif t switch to 2WD.
