2015 NISSAN TITAN engine

●When the warning light comes on, the
2WD mode may be engaged even if the
4WD shift switch is in 4H. Be especially
careful when driving. If corresponding
parts are malfunctioning, the 4WD
mode will not be engaged even if the
4WD shift switch is shifted.
● Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing 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 surface roads:
– in the 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position, stop the vehicle, move the automatic transmission
shift lever to the N position with the
brake pedal depressed, and shift the
4WD shift switch to 2WD.
●
If the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.
● The transfer case may be damaged if
you continue driving with the warning
light blinking. The E-Lock system can provide additional trac-
tion and should only be used when a vehicle has
become or is becoming stuck. This system oper-
ates by electronically “locking” the two rear drive
wheels together, 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 vehicles) .
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 indi-
cator 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 system 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 Brake (ABS) system is disabled
and the ABS light illuminates when the E-Lock
system is ON. Also, the Vehicle Dynamic Control
(VDC) system is disabled and the VDC 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. After us-
ing the E-Lock system to free the ve-
hicle, turn the system OFF.
● Use the E-Lock system only when free-
ing a stuck vehicle. Try the 4LO position
before using the E-Lock system. Never
use the E-Lock system on a slippery
road surface such as snow or ice sur-
face. Using the E-Lock system when
driving in these road conditions may
cause unexpected movement of the ve-
hicle during engine braking, accelerat-
ing or turning, which may result in an
accident and serious personal injury.

CAUTION
●After using the E-Lock system, turn the
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 sys-
tem 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.
WARNING
● 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.
● Safe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park) . Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and re-
sult in an accident. Make sure the shift
lever has been pushed as far forward as
it can go and cannot be moved without
depressing the foot brake pedal. ●
Never leave the engine running while
the vehicle is unattended.
● Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended
children could become involved in seri-
ous accidents.
1. Firmly apply the parking brake.
2. Move the shift lever to the P (Park) position.
3. To help prevent the vehicle from rolling into traffic when parked on an incline, it is a good
practice to turn the wheels as illustrated.

●HEADED DOWNHILL WITH CURB:A
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
● HEADED UPHILL WITH CURB:
B
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:
C
Turn the wheels toward the side of the road
so the vehicle will move away from the cen-
ter of the road if it moves.
4. Place the ignition switch in the LOCK posi- tion. The power assisted steering uses a hydraulic
pump, driven by the engine, to assist 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 hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
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
downshift 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.
POWER STEERING
BRAKE SYSTEM
Starting and driving5-33

WARNING
●While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating 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.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer 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
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or drum/rotors
are replaced, in order to assure the best brake
performance. This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●
The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces 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 vehicle in front of
you. Ultimately, the driver is respon-
sible for safety.
● Tire type and condition may also affect
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 additional in-
formation, refer to “Tire and Loading
Information label” in the “Technical
and consumer information” section
of this manual.
– For additional information, refer to “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (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 slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
5-34Starting and driving

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The 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 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
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates 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 vehicle
checked by a NISSAN dealer.
Normal operation
The ABS operates 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 ap-
plies and releases hydraulic pressure. This action
is similar to pumping the brakes very quickly. You
may feel a pulsation 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 operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional 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 driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle at all times.
●
ABLS system uses automatic braking to
transfer power from a slipping drive wheel to
the wheel on the same axle with more trac-
tion. The ABLS system applies braking to
the slipping wheel, which helps redirect
power to the other wheel.
● On 4WD models the ABLS system operates
in both 4H and 4LO modes. If 4WD mode is
engaged, the ABLS system operates for
both drive axles. On 2WD vehicles, the
ABLS system operates on the drive axle
only.
● The ABLS system is always ON. In some
conditions, the system may automatically
turn the ABLS system off. If the system is
automatically turned off, normal brake func-
tion will continue. ABLS will function even
when the VDC 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 driving5-35

WARNING
●The ABLS system helps provide in-
creased traction, but will not prevent
accidents due to abrupt steering opera-
tion or by careless driving or dangerous
driving practices. Reduce vehicle speed
and be especially careful when driving
and cornering on slippery surfaces. Al-
ways drive carefully.
●
Do not modify the vehicle’s suspension. If
suspension parts such as shock absorb-
ers, struts, springs, stabilizer bars, bush-
ings and wheels are not NISSAN ap-
proved for your vehicle or are extremely
deteriorated, the ABLS system may not
operate properly. This could adversely af-
fect vehicle 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 extremely
deteriorated, the ABLS system 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 Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle 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 function) .
● If the 4WD transfer case is shifted into 4LO
the
indicator light will come on and
the VDC system will be turned off. For addi-
tional information, refer to “Using 4-wheel
drive (4WD)” in this section.
● Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing 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 cannot prevent loss of
vehicle control in all driving situations.
When the VDC system operates, the
indi-
cator in the instrument panel flashes so note the
following:
● The road may be slippery or the system may
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 indicates that the
VDC system is working properly.
● Adjust your speed and driving to the road
conditions.
For additional information, refer to “Slip indicator
light” and ”Vehicle Dynamic Control (VDC) OFF
indicator light” in the ”Instruments and controls”
section of this manual.
If a malfunction occurs in the system, the
indicator light will come on in the instrument
panel. The VDC system automatically turns off
when these indicator lights are off.
The VDC OFF switch is used to turn off the VDC
system. The
indicator illuminates to indi-
cate the VDC system is off.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-36Starting and driving

When the VDC 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 flashes if this occurs. All other VDC
functions are off and the
indicator 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 feature
that tests the system each time you start the
engine and move the vehicle forward 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
indication of a malfunction.
WARNING
● The VDC system is designed to help the
driver maintain stability but does not
prevent accidents due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully. ●
Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
recommended for your vehicle or are
extremely deteriorated, the VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the
indicator may
flash or the
indicator light may
illuminate.
● If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extremely
deteriorated, the VDC system may not
operate properly and the
indica-
tor light may illuminate.
● If engine control related parts are not
NISSAN recommended or are extremely
deteriorated, the
indicator light
may illuminate.
● When driving on extremely inclined sur-
faces such as higher banked corners,
the VDC system may not operate prop-
erly and the
indicator may flash or
the
indicator 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 may flash or
the
indicator light may illuminate.
This is not a malfunction. Restart the
engine after driving onto a stable
surface.
● If wheels or tires other than the NISSAN
recommended ones are used, the VDC
system may not operate properly and
the
indicator may flash or
the
indicator 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 four wheels depending on the radius of the
turn.
