2019 NISSAN FRONTIER 4WD

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.

4WD shif t indicator light
The 4WD shif t indicator light is located in
the odometer display.
The light should turn off within 1 second
af ter placing the ignition switch in the ON
position.
While the engine is running, the 4WD shif t
indicator light will illuminate the position
selected by the 4WD shif t switch.∙
The 4WD shif t indicator light may
blink while shif ting from one drive
mode to the other. When the shif ting
is completed, the 4WD shif t indicator
light will come on.
∙ If the 4WD warning light comes on, the 4WD shif t indicator light goes out.
CAUTION
If the 4WD shif t indicator light indica-
tion changes to 2WD when the 4WD
shif t switch is shif ted to the 4H position
at low ambient temperatures, the 2WD
mode may be being engaged due to
malfunctioning drive system. If the in-
dicator does not return to normal and
the 4WD warning light comes on, have
the system checked. It is recommended
that you visit a NISSAN dealer for this
service.

The 4WD warning light is located in the me-
ter.
The 4WD warning light comes on when the
ignition switch is placed in the ON position.
It turns off soon af ter the engine is started.
If any malfunction occurs in the 4WD sys-
tem when the ignition switch is ON, the
warning light will either remain illuminated
or blink.
If the 4WD warning light comes on, the 4WD
shif t indicator light goes out.LSD0147
Starting and driving5-31

A large difference between the diameters
of front and rear wheels will make the
warning light blink slowly (about once per
2 seconds). Change the 4WD shif t switch
into 2WD and do not drive fast.
CAUTION
∙ If the warning light comes on or blinksslowly during operation, have your
vehicle checked as soon as possible. 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 light turns on.
∙ When the warning light comes on, the 2WD mode may be engaged even if
the 4WD shif t switch is in 4H. Be espe-
cially careful when driving. If corre-
sponding parts are malfunctioning,
the 4WD mode will not be engaged
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 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 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. ∙ The transfer case may be damaged if
you continue driving with the warning
light blinking.
5-32Starting and driving

Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The Anti-lock Braking System (ABS) includes
electronic sensors, electric pumps, hydraulic
solenoids and a computer. The computer
has a built-in diagnostic feature that tests
the system each time you start the engine
and move the vehicle at a low speed in for-
ward or reverse. When the self-test occurs,
you may hear a “clunk” noise and/or feel a
pulsation in the brake pedal. This is normal
and does not indicate a malfunction. If the
computer senses a malfunction, it switches
the ABS off and illuminates the ABS warning
light on the instrument panel. The brake sys-
tem then operates normally but without
anti-lock assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds above3-6mph(5-
10 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion in the brake pedal and hear a noise
from under the hood or feel a vibration
from the actuator when it is operating. This
is normal and indicates that the ABS is op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving. ∙ The ABLS system uses automatic brak-
ing to transfer power from a slipping
drive wheel to the wheel on the same
axle with more traction. The ABLS sys-
tem applies braking to the slipping
wheel, which helps redirect power to
the other wheel.
∙ On 4–Wheel Drive models the ABLS sys- tem operates in both 4H and 4LO
modes. If 4WD mode is engaged, the
ABLS system operates for both drive
axles. On 2–Wheel Drive vehicles, the
ABLS system operates on the drive axle
only.
∙ The ABLS system is always on. In some conditions, the system may automati-
cally turn the ABLS system off. If the sys-
tem is automatically turned off, normal
brake function will continue. ABLS will
function even when the Vehicle Dy-
namic Control system is turned off.
∙ The ABLS does not operate if both wheels on a drive axle are slipping.
ACTIVE BRAKE LIMITED SLIP (ABLS)
SYSTEM
Starting and driving5-37

WARNING
∙ The ABLS system helps provide in-creased traction, but will not prevent
accidents due to abrupt steering op-
eration or by careless driving or dan-
gerous driving practices. Reduce ve-
hicle speed and be especially careful
when driving and cornering on slip-
pery surfaces. Always drive carefully.
∙ Do not modif y the vehicle’s suspen- sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not NISSAN approved for your vehicle
or are extremely deteriorated, the
ABLS system may not operate prop-
erly. This could adversely affect ve-
hicle handling performance, and the
slip indicator light may illuminate.
∙ If brake related parts such as brake pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the ABLS sys-
tem may not operate properly and the
slip indicator light may illuminate. ∙ If wheels or tires other than the
NISSAN recommended ones are used,
the ABLS system may not operate
properly and the slip indicator light
may illuminate. The VDC system uses various sensors to
monitor driver inputs and vehicle motion.
Under certain driving conditions, the VDC
system helps to perform the following
functions:
∙ Controls brake pressure to reduce wheel slip on one slipping drive wheel
so power is transferred to a non-
slipping drive wheel on the same axle.
∙ Controls brake pressure and engine output to reduce drive wheel slip based
on vehicle speed (traction control func-
tion).
∙ If the 4WD transfer case is shif ted into 4LO the
indicator light will come
on and the VDC system will be turned
off. For additional information, refer to
“Using 4–Wheel Drive (4WD)” in this sec-
tion.
∙ Controls brake pressure at individual wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
– Understeer (vehicle tends to not fol- low the steered path despite in-
creased steering input)
– Oversteer (vehicle tends to spin due to certain road or driving conditions)
