2017 NISSAN ARMADA brakes

FEB SYSTEM OPERATION
The FEB system operates at speeds above
approximately 3 MPH (5 km/h) .
If a risk of a forward collision is detected, the
FEB system will provide the first warning to the
driver by illuminating the warning in the vehicle
information display and providing an audible
warning. In addition, the FEB system pushes the
accelerator pedal up. If the driver releases the
accelerator pedal, then the system applies
partial braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the FEB system
detects that there is still the possibility of a
forward collision, the system will automatically
increase the braking force.
If a forward collision is imminent and the driver
does not take action, the FEB system issues the
second visual (flashing) and audible warning and
automatically applies harder braking.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the FEB system.
Depending on vehicle speed and distance to the
vehicle ahead, as well as driving and roadway
conditions, the system may help the driver avoid
a forward collision or may help mitigate the
consequences of a collision should one beunavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the FEB system will
function later or will not function.
The automatic braking will cease under the
following conditions:
.
When the steering wheel is turned as far as
necessary to avoid a collision.
. When the accelerator pedal is depressed.
. When there is no longer a vehicle detected
ahead.
If the FEB system has stopped the vehicle, the
vehicle will remain at a standstill for approxi-
mately 2 seconds before the brakes are
released.

WARNING
.Never rely solely on the hill start
assist system to prevent the vehicle
from moving backward on a hill.
Always drive carefully and atten-
tively. 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
designed to hold the vehicle at a
standstill 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 system may not
prevent the vehicle from rolling
backwards on a hill under all load
or road conditions. Always be pre-
pared to depress the brake pedal to prevent the vehicle from rolling
backwards. Failure to do so may
result in a collision or serious per-
sonal injury.
The hill start assist system automatically keeps
the brakes applied to help prevent the vehicle
from rolling backwards in the time it takes the
driver to release the brake pedal and apply the
accelerator when the vehicle is stopped on a hill.
The hill start assist system will operate auto-
matically under the following conditions:
. The transmission is shifted 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. After 2
seconds the vehicle will begin to roll back and
the hill start assist system will stop operating
completely.
The hill start assist system will not operate when
the transmission is shifted to the N (Neutral) or P
(Park) position or on a flat and level road.
When the Vehicle Dynamic Control (VDC)
warning light illuminates in the meter, the hill
start assist system will not operate. (See
“Warning lights, indicator lights and audible
reminders” (P.2-10).)

BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking ability at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed slowly.
This is not a malfunction and indicates that the
brake assist mechanism is operating properly.
Hydraulically-assisted brakes
The hydraulically-assisted brake system is de-
signed to use a hydraulic pump driven electri-
cally, to assist braking. If the engine stops, you
can stop the vehicle by depressing the foot
brake pedal. However, greater foot pressure on
the foot brake pedal will be required to stop the
vehicle. The stopping distance will be longer.
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 brakes, drive the vehicle at a safe speed
while lightly tapping 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 performance.
This procedure is described in the vehicle
service manual. It is recommended you visit a
NISSAN dealer for this service.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake and pads faster
and reduce gas mileage.
To help save the brakes 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.
WARNING
.While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating 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.
BRAKE SYSTEM

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 vehicle at
all times.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal surfaces even with ABS. Stopping
distances 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 responsible
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. See “Tire and loading
information label” (P.10-12) .
— For detailed information, see “Wheels and tires” (P.8-30) .
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
prevent 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
ABS 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.
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 malfunction, it switches the ABS off and
Starting and driving5-137
BRAKE ASSIST

5-138Starting and driving
illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked. It is recommended you visit a NISSAN
dealer for this service.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 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 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 pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving con-
ditions, 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) .
. 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 cannot prevent loss
of vehicle control in all driving situations.
When the VDC system operates, the VDC
warning light
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.
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator
illuminates to
indicate the VDC system is off. 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 VDC warning light
flashes if this occurs. All other VDC functions
are off, and the VDC warning lightwill 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.
When the 4L position is selected with the 4WD
shift switch, the VDC system is disabled and the
VDC off indicator light illuminates (for 4WD
models) .
See “Vehicle Dynamic Control (VDC) warning
light” (P.2-17) and “Vehicle Dynamic Control
(VDC) off indicator light” (P.2-20).

Be careful not to clog the washer nozzle*A.
This may cause improper windshield washer
operation. If the nozzle is clogged, remove any
objects with a needle or small pin
*B.Be
careful not to damage the nozzle. It is recommended you visit a NISSAN dealer if
checking or replacement is required.
If the brakes do not operate properly, it is
recommended you have the brakes checked by
a NISSAN dealer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
WARNING
Have your brake system checked if the
brake pedal height does not return to
normal. It is recommended you visit a
NISSAN dealer for this service.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear warn-
ings. When a brake pad requires replacement, it
will make a high pitched scraping sound when
the vehicle is in motion. This scraping sound will
first occur only when the brake pedal is
depressed. After more wear of the brake pad,
the sound will always be heard even if the brake
pedal is not depressed. Have the brakes
checked as soon as possible if the wear warning
sound is heard.
Under some driving or climate conditions,

8-18Do-it-yourself
occasional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does not
affect the function or performance of the brake
system.
Proper brake inspection intervals should
be followed.For additional information, see the
maintenance schedule shown in the “9. Main-
tenance and schedules” section.
BRAKE BOOSTER
Check the brake booster function as follows:
1. With the engine off, depress and release the foot brake pedal more than 20 times. When
the foot brake pedal movement (distance of
travel) remains the same from one pedal
application to the next, continue on to the
next step.
2. While depressing the foot brake pedal, start the engine.
3. With the foot brake pedal depressed, stop the engine. Keep the pedal depressed for
about 30 seconds.
4. Run the engine for 1 minute without depressing the foot brake pedal, then turn
it off. Depress the foot brake pedal several
times. The pedal travel distance will de-
crease gradually with each depression as
the hydraulic pressure decreases. If the brakes do not operate properly, have the
brakes checked. It is recommended that you visit
a NISSAN dealer for repair.
