2021 NISSAN TITAN warning light

–In the 4LO position, stop the ve-
hicle, move the automatic trans-
mission shif t lever to the N (Neu-
tral) position with the brake pedal
depressed, and shif t the 4WD shif t
switch to 2WD.
• If the warning message is still on af-
ter the above operation, have your
vehicle checked as soon as possible.
It is recommended that you visit a
NISSAN dealer for this service.
• The transfer case may be damaged if
you continue driving with the warn-
ing message on. 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, see “Elec-
tronic locking rear differential (E-Lock) sys-
tem switch” (P. 2-59). Once the system fully
engages, the indicator light in the instru-
ment panel will remain on. When the sys-
tem is activated, both rear wheels will en-
gage, 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 System (ABS) is dis-
abled and the ABS warning light illumi-
nates 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 per-
sonal injury. Af ter using the E-Lock
system to free the vehicle, turn the
system off.
• Use the E-Lock system only in an
emergency when it is not possible to
free a stuck vehicle even when using
4LO. Never use the E-Lock system on
a slippery road surface such as snow
or ice surface. Using the E-Lock sys-
tem when driving in these road con-
ditions may cause unexpected
movement of the vehicle during en-
gine braking, accelerating or turning,
which may result in an accident and
serious personal injury.
• Observe the above warnings. Other-
wise, loss of normal steering control
may result. This may result in an ac-
cident and serious personal injury.

Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be lon-
ger and the vehicle may pull to one side
during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake
pedal to heat up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakes
function correctly.
Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
• The ABS is a sophisticated device, but
it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if
you are using tire chains. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
• Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
–
When installing a spare tire, make sure that it is the proper size and
type as specified on the Tire and
Loading Information label. For ad-
ditional information, see “Tire and
Loading Information label” (P. 8-37).
– For additional information, see
“Wheels and tires” (P. 8-35)
The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
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 dis-
tances.
5-116Starting and driving

Self-test feature
The Anti-lock Braking System (ABS) in-
cludes 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 forward 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 mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates the ABS warning light on the
instrument panel. The brake system 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.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert,
drive safely and be in control of the ve-
hicle at all times. • 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 system applies
braking to the slipping wheel, which helps
redirect power to the other wheel.
• On 4–Wheel Drive (4WD) models the ABLS system operates in both 4H and 4LO
modes. If 4WD mode is engaged, the
ABLS system operates for both drive ax-
les. 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 Dynamic
Control system is turned off.
• The ABLS system does not operate if both wheels on a drive axle are slipping.
ACTIVE BRAKE LIMITED SLIP (ABLS)
SYSTEM
Starting and driving5-117

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 oper-
ate 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 out- put to reduce drive wheel slip based on
vehicle speed (traction control function).
• 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, see “Using
4-Wheel Drive (4WD)” (P. 5-105).
• 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 follow the steered path despite increased
steering input)
– Oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to
maintain control of the vehicle, but it can-
not prevent loss of vehicle control in all driv-
ing situations.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-118Starting and driving

When the VDC system operates, theindicator light in the instrument panel
flashes so note the following:
• The road may be slippery or the systemmay determine some action is required
to help keep the vehicle on the steered
path.
• You may feel a pulsation in the brake pedal and hear a noise or vibration from
under the hood. This is normal and indi-
cates that the VDC system is working
properly.
• Adjust your speed and driving to the road conditions.
For additional information, see “Slip indica-
tor light” (P. 2-21) and “Vehicle Dynamic Con-
trol (VDC) OFF indicator light” (P. 2-21).
If a malfunction occurs in the system, the
indicator light will come on in the in-
strument panel. The VDC system auto-
matically turns off when these indicator
light is on.
The VDC OFF switch is used to turn off the
VDC system. The
indicator light illumi-
nates to indicate the VDC system is off.
When the VDC OFF switch is used to turn off
the system, the VDC system still operates
to prevent one drive wheel from slipping by
transferring power to a non-slipping drive wheel. The
indicator light flashes if this
occurs. All other VDC functions are off and
the
indicator light will not flash.
The VDC system is automatically reset to
ON when the ignition switch is placed in the
OFF position then back to the ON position.
The computer has a built-in diagnostic fea-
ture that tests the system each time you
start the engine and move the vehicle for-
ward or in reverse at a slow speed. When
the self-test occurs, you may hear a clunk
noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indica-
tion of a malfunction.
WARNING
• The VDC system is designed to help
the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed
and be especially careful when driv-
ing and cornering on slippery sur-
faces and 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 recommended for your
vehicle or are extremely deterio-
rated, the VDC system may not oper-
ate properly. This could adversely af-
fect vehicle handling performance,
and the
indicator light may flash
or theindicator light may
illuminate.
• If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC sys-
tem may not operate properly and
the
indicator light may
illuminate.
• If engine control related parts are not
NISSAN recommended or are ex-
tremely deteriorated, the
indi-
cator light may illuminate.
• When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the
indicator
light may flash or theindicator
light may illuminate. Do not drive on
these types of roads.

•When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator light may
flash or theindicator light may
illuminate. This is not a malfunction.
Restart the engine af ter driving onto
a stable surface.
• If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not oper-
ate properly and the
indicator
light may flash or theindicator
light may illuminate.
• The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the front and rear wheels
depending on the radius of the turn.
WARNING
• The VDC system is designed to help
the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed
and be especially careful when driv-
ing and cornering on slippery sur-
faces and always drive carefully.

5-120Starting and driving

WARNING
• Never rely solely on the hill descent
control system to control vehicle
speed when driving on steep down-
hill grades. Always drive carefully and
attentively when using the hill de-
scent control system and decelerate
the vehicle speed by depressing the
brake pedal if necessary. Be espe-
cially careful when driving on frozen,
muddy or extremely steep downhill
roads. Failure to control vehicle
speed may result in a loss of control
of the vehicle and possible serious
injury or death.
• The hill descent control may not con-
trol the vehicle speed on a hill under
all load or road conditions. Always be
prepared to depress the brake pedal
to control vehicle speed. Failure to do
so may result in a collision or serious
personal injury. The hill descent control system can only be
activated when the 4H or 4LO position is
engaged.
The hill descent control system helps
maintain vehicle speed when driving under
15 mph (25 km/h) on steeper downhill
grades. Hill descent control is useful when
engine braking alone cannot control ve-
hicle speed. Hill descent control applies the
vehicle brakes to control vehicle speed al-
lowing the driver to concentrate on steer-
ing while reducing the burden of brake and
accelerator operation.
If the hill descent control system ON indica-
tor light is blinking, the hill descent control
is engaged; however, the hill descent con-
trol will not control the vehicle speed.
• Once the system is activated, the indica-
tor light will remain on in the instrument
panel. For additional information, see “Hill
descent control system ON indicator
light” (P. 2-18).
• You may hear a noise from under the hood or feel a vibration from the actuator
when it is operating. This indicates that
the hill descent control system is working
properly. If the accelerator or brake pedal is de-
pressed while the hill descent control sys-
tem is on, the system will stop operating
temporarily. As soon as the accelerator or
brake pedal is released, the hill descent
control system begins to function again if
the hill descent control operating condi-
tions are fulfilled.
For the best results, when descending
steep downhill grades, the hill descent con-
trol switch should be ON and the shif t lever
in M1 (First) for engine braking. For addi-
tional information, see “Hill descent control
switch” (P. 2-58).
HILL DESCENT CONTROL SYSTEM (if
so equipped)
Starting and driving5-121

WARNING
• Never rely solely on the hill start as-
sist system to prevent the vehicle
from moving backward on a hill. Al-
ways drive carefully and attentively.
Depress the brake pedal when the
vehicle is stopped on a steep hill. Be
especially careful when stopped on a
hill on frozen or muddy roads. Failure
to prevent the vehicle from rolling
backwards may result in a loss of
control of the vehicle and possible
serious injury or death.
• The hill start assist system is not de-
signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Failure to do so may cause
the vehicle to roll backwards and
may result in a collision or serious
personal injury.
• The hill start assist may not prevent
the vehicle from rolling backwards
on a hill under all load or road condi-
tions. Always be prepared to depress
the brake pedal to prevent the ve-
hicle from rolling backwards. Failure
to do so may result in a collision or
serious personal injury. When the vehicle is stopped on a hill, the hill
start assist system automatically keeps
the brakes applied. This helps prevents the
vehicle from rolling backward in the time it
takes the driver to release the brake pedal
and apply the accelerator when the vehicle
is stopped on a hill.
Hill start assist will operate automatically
under the following conditions:
• The shif t lever is shif ted to a forward or
reverse gear.
• The vehicle is stopped completely on a hill by applying the brake.
The maximum holding time is 2 seconds.
Af ter 2 seconds the vehicle will begin to roll
back and hill start assist will stop operating
completely.
Hill start assist will not operate when the
shif t lever is shif ted into N (Neutral) or P
(Park) or on a flat and level road. When the
indicator light illuminates in the meter,
the hill start assist system will not operate. The front and rear sonar system sounds a
tone to inform the driver of obstacles near
the bumper.
When the “DISPLAY” key is ON, the sonar
view will automatically appear in the meter.WARNING
• The front and rear sonar system is a
convenience but it is not a substitute
for proper parking.
