2019 NISSAN FRONTIER engine

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 re-
sult in shortened engine life and re-
duced engine performance.∙ Avoid driving for long periods at con- stant 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 pos- sible.
∙ 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 pos-
sible.
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 Dis-
tances
∙ Observing the speed limit and not exceeding 60 mph (97 km/h) (where
legally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
∙ Maintaining a safe following distance behind other vehicles reduces un-
necessary braking.
∙ Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
∙ Select a gear range suitable to road conditions.
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS
5-24Starting and driving

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.
7. Avoid Idling
∙ Shutting off your engine when safe for stops exceeding 30–60 seconds
saves fuel and reduces emissions.
8. Buy an Automated Pass for Toll
Roads
∙ Automated passes permit drivers to use special lanes to maintain cruis-
ing speed through the toll and avoid
stopping and starting. 9.
Winter Warm Up
∙ Limit idling time to minimize impact to fuel economy.
∙ Vehicles typically need no more than 30 seconds of idling at start-up to
effectively circulate the engine oil be-
fore driving.
∙ Your vehicle will reach its ideal oper- ating temperature more quickly
while driving versus idling.
10. Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases
tire wear and lowers fuel economy.
∙ Keep the wheels in correct alignment. Improper 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, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer
information” section of this manual.

WARNING
∙ For 4WD equipped vehicles, do not at-tempt 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 personal
injury.
∙ Do not attempt to test a 4WD equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions
testing), or similar equipment even if
the other two wheels are raised off the
ground. Make sure you inform test fa-
cility personnel that your vehicle is
equipped with 4WD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drive-
train damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal
injury.
CAUTION
∙ Do not drive the vehicle in the 4H or4LO 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 light turns on
when you are driving on dry hard sur-
face roads:
– In the 4H position, shif t the 4WD shif t switch to 2–Wheel Drive
(2WD).
– In the 4LO position for automatic transmission vehicles, stop the ve-
hicle and shif t the shif t lever to the
N (Neutral) position with the brake
pedal depressed and shif t the 4WD
shif t switch to 2WD.
– In the 4LO position for manual transmission vehicles, stop the ve-
hicle and shif t the shif t lever to the
N (Neutral) position with the clutch
pedal depressed and shif t the 4WD
shif t switch to 2WD. ∙ If the warning light 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.
TRANSFER CASE SHIFTING
PROCEDURES
The part-time 4WD system provides three
positions (2WD, 4H and 4LO), so you can
select the desired drive mode according to
the driving conditions.
USING 4–WHEEL DRIVE (4WD)
(if so equipped)
5-26Starting and driving

1. Turn off the engine by turning the ignition switch off.
2. Start the engine.
- Check that the 4WD warning light turns off. If the 4WD warning light illuminates, have the system checked. It is recommended that you
visit a NISSAN dealer for this service.
3. Apply the parking brake, for A/T vehicles, depress the brake pedal and move the shif t lever to N (Neutral) position. For M/T vehicles,
move the shif t lever to the N (Neutral) position.
4. With the brake pedal depressed on A/T vehicles or with the clutch pedal depressed on M/T vehicles, move the 4WD shif t switch to
the desired mode.
- Be sure to wait until the transfer gear change completes before shif ting the shif t lever from the N (Neutral) position.
*2: While changing in and out of 4LO, the ignition key must be on and the vehicle’s engine must be running for a shif t to take place and for the indicator lights (4WD shif t and 4LO position indicator) to be operable. Otherwise, the shif t will not take place and no indicator lights
will be on or flashing.
*3: Make sure the transfer 4LO position indicator light turns on when you shif t the 4WD shif t switch to 4LO. The
indicator light will also
turn on when 4LO is selected. For additional information, refer to “Vehicle Dynamic Control (VDC) system” in this section.
5-28Starting and driving

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 for A/T vehicles de-
press the brake pedal or for M/T vehicles
depress the clutch pedal. The switch
must be depressed and turned when
changing into or out of 4LO.
WARNING
∙ When parking, apply the parkingbrake before stopping the engine and
make sure that the 4WD shif t indica-
tor light is on and the ATP warning
light goes off. Otherwise, the vehicle
could unexpectedly move even if the
A/T is in the P (Park) position. ∙ The transfer 4LO position indicator
light 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
transfer 4LO position indicator light is
blinking, 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 compo-
nents. 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 engine
brake and low A/T gears 2 (Second
gear) or 1 (Low gear), or M/T (1st gear
or 2nd gear) 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. Driving on
dry hard surfaces in 4H or 4LO may
cause unnecessary noise and tire
wear. NISSAN recommends driving 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 trans-
fer 4LO position indicator light 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 be-
tween 4H and 4LO.
Starting and driving5-29

When driving on rough roads:∙ Set the 4WD shif t switch to 4H or 4LO.
∙ Drive carefully according to the road surface conditions.
When the vehicle is stuck: ∙ Set the 4WD shif t switch to 4H or 4LO.
∙ Use the Electronic Locking Rear Differ- ential (E-Lock) system (if so equipped).
Turn the switch ON while the vehicle is
stationary and apply the throttle to try
to free the vehicle.
∙ If it is difficult to free the vehicle, rock the vehicle back and forth between R (Re-
verse) and D (Drive) gears.
∙ If the vehicle is stuck deep in mud, place stones or wooden blocks under the
tires. Then try the recovery procedures
above. Tire chains may be effective.
CAUTION
∙ Do not spin the tires excessively. Tireswill sink deep into the mud, making it
difficult to free the vehicle.
∙ Avoid shif ting gears with the engine running at high speeds as this may
cause malfunction.
4WD shif t switch operations
∙ Shif t the 4WD shif t switch to either the
2WD, 4H or 4LO position, depending on
driving conditions.
∙ If the 4WD shif t switch is operated
while making a turn, accelerating or
decelerating or if the key switch is
turned off while in the 4H or 4LO posi-
tion, you may feel a jolt. This is not
abnormal. ∙
When the vehicle is stopped af ter
making a turn, you may feel a slight
jolt af ter the shif t lever is moved to N
(Neutral) or P (Park). This occurs be-
cause the transfer clutch is released
and not because of a malfunction.
CAUTION
∙ 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 while driving on steep downhill
grades. Use the engine brake and low
automatic transmission gears 2 (Sec-
ond gear) or 1 (Low gear) or manual
transmission (1st gear or 2nd gear) for
engine braking.
∙ Do not operate the 4WD shif t switch with the rear wheels spinning.
∙ Before placing the 4WD shif t switch in the 4H position from 2WD, ensure the
vehicle speed is less than 62 mph
(100 km/h). Failure to do so can dam-
age the 4WD system.
∙ Never shif t the 4WD shif t switch be- tween 4LO and 4H while driving.

The E-Lock system can provide additional
traction and should only be used when a
vehicle has become or is becoming stuck.
This system operates by electronically
“locking” the two rear drive wheels to-
gether, allowing them to turn at the same
speed. The system is used when it is not
possible to free a stuck vehicle even when
using the 4LO position (4-Wheel Drive ve-
hicles).
When added traction is required, activate
the E-Lock system by pushing the switch
ON. For additional information, refer to
“Electronic locking rear differential (E-Lock)
system switch” in the “Instruments and
controls” section of this manual. Once the
system fully engages, the indicator light in
the instrument panel will remain on. When
the system is activated, both rear wheels
will engage, providing added traction.
The rear wheels may momentarily slip or
move to engage the system, and the sys-
tem will only engage up to approximately
4 mph (7 km/h). Once the vehicle is free, the
system should be turned off and driving
resumed.The Anti-Lock Braking (ABS) system is dis-
abled and the ABS light illuminates when
the E-Lock system is on. Also, the Vehicle
Dynamic Control (VDC) system is disabled
and the
indicator light illuminates
when the E-Lock system is on.
WARNING
∙ Never leave the E-Lock system on when driving on paved or hard-
surfaced roads. Turning the vehicle
may result in the rear wheels slipping
and result in an accident and personal
injury. Af ter using the E-Lock system
to free the vehicle, turn the system off.
∙ Use the E-Lock system only when freeing a stuck vehicle. Try the 4LO po-
sition before using the E-Lock system.
Never use the E-Lock system on a slip-
pery road surface such as snow or ice
surface. Using the E-Lock system
when driving in these road conditions
may cause unexpected movement of
the vehicle during engine braking, ac-
celerating or turning, which may re-
sult in an accident and serious per-
sonal injury.
CAUTION
∙ Af ter using the E-Lock system, turnthe switch OFF to prevent possible
damage to driveline components
from extended use.
∙ Do not drive the vehicle at speeds faster than 12 mph (20 km/h) when
the system is engaged. Doing so could
damage drivetrain components.
∙ Do not turn on the E-Lock system while the tires are spinning. Doing so
could damage drivetrain
components.
