brakes NISSAN PATHFINDER 2023 Owner's Manual

–The braking force becomes poor
due to wet brakes af ter driving
through a puddle or washing the
vehicle.
• Turn the RAB system off in the follow-
ing conditions to prevent the occur-
rence of an unexpected accident re-
sulting from sudden system
operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed
truck.
– The vehicle is on the chassis
dynamometer.
– The vehicle drives on an uneven
road surface.
– The vehicle is towing an object (if
so equipped).
– Suspension parts other than
those designated as Genuine
NISSAN parts are used. (If the ve-
hicle height or the vehicle body in-
clination is changed, the system
may not detect an obstacle
correctly.)
– If the vehicle is using an accessory
like a bike rack, or cargo carrier
that blocks the sensors. •
Excessive noise (e.g., audio system
volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “Mal-
function” warning message will appear in
the vehicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.
SYSTEM MAINTENANCE
Observe the following items to ensure
proper operation of the system:
• Always keep the parking sensors
O1
clean.
• If the parking sensors are dirty, wipe them off with a sof t cloth while being careful to
not damage them.

AEB WITH PEDESTRIAN
DETECTION SYSTEM OPERATION1. Vehicle ahead detection indicator
2. AEB with Pedestrian Detection emer-gency warning indicator 3. AEB with Pedestrian Detection system
OFF warning light
The AEB system operates at speeds above
approximately 3 mph (5 km/h). For the pe-
destrian and cyclist detection function, the
system operates at speeds betwee n6–37
mph (10 – 60 km/h).
If a risk of a forward collision is detected, the
AEB with Pedestrian Detection system will
firstly provide the warning to the driver by
flashing the vehicle ahead detection indica-
tor (yellow) in the vehicle information display
and providing an audible alert. If the driver
applies the brakes quickly and forcefully af ter
the warning, and the AEB with Pedestrian De-
tection system detects that there is still the
possibility of a forward collision, the system
will automatically increase the braking force.
If the driver does not take action, the AEB with
Pedestrian Detection system issues the sec-
ond visual (flashing) (red and white) and au-
dible warning. If the driver releases the accel-
erator pedal, then the system applies partial
braking. If the risk of a collision becomes im-
minent, the AEB with Pedestrian Detection
system applies harder braking automatically.
While the AEB with Pedestrian Detection
system is operating, you may hear the
sound of brake operation. This is normal
and indicates that the AEB with Pedestrian
Detection system is operating properly.

5-138Starting and driving

NOTE:
The vehicle’s brake lights come on when
any braking is performed by the AEB
with Pedestrian Detection system.
Depending on vehicle speed and distance
to the vehicle, pedestrian or cyclist ahead,
as well as driving and roadway conditions,
the system may help the driver avoid a
forward collision or may help mitigate the
consequences if a collision should be un-
avoidable. If the driver is handling the steer-
ing wheel, accelerating or braking, the AEB
with Pedestrian Detection system function
will be delayed or will not function.
The automatic braking will cease under the
following conditions:
• When the steering wheel is turned toavoid a collision.
• When the accelerator pedal is depressed.
• When there is no longer a vehicle or a pedestrian detected ahead.
If the AEB with Pedestrian Detection sys-
tem has stopped the vehicle, the vehicle
will remain at a standstill for approximately
2 seconds before the brakes are released.

Starting and driving5-139

The brake system has two separate hy-
draulic 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 pres-
sure on the brake pedal will be required to
stop the vehicle and stopping distance 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 downshif t 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 downshif ting. 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.
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 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 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.
BRAKE SYSTEM
Starting and driving5-175

•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. 8-30).
– For additional information, see
“Wheels and tires” (P. 8-28).
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
distances.
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 abov
e3-6mph(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.
5-176Starting and driving

If the chassis control system error warning
message appears in the vehicle informa-
tion display, it may indicate that the ARC is
not functioning properly. Have the system
checked as soon as possible. It is recom-
mended that you visit a NISSAN dealer for
this service.
WARNING
The ARC may not be effective depend-
ing on the driving condition. Always
drive carefully and attentively.
When the ARC is operating, you may feel a
pulsation in the brake pedal and hear a
noise. This is normal and indicates that the
ARC is operating properly. You may also feel
deceleration when the ARC is operating.
However, this is not a malfunction.
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 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. The hill descent
control system will only work in the Sand
and Mud/Rut mode.
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).
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.
HILL DESCENT CONTROL SYSTEM (if
so equipped)
5-182Starting and driving

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. The hill start assist system automatically
keeps the brakes applied to help prevent
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 moved 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 position is moved to N (Neutral) or P
(Park), or on a flat and level road. The sonar system sounds a tone to inform
the driver of obstacles around the vehicle
using the sonar sensors located in the
front and rear bumpers..
When the sonar system is turned on, the
sonar view will automatically appear in the
vehicle information display.
WARNING
• The sonar system is a convenience
but it is not a substitute for proper
parking.

•The driver is always responsible for
safety during parking and other ma-
neuvers. Always look around and
check that it is safe to do so before
parking.
• Read and understand the limitations
of the sonar system as contained in
this section. The colors of the corner
sonar indicator indicates different
distances to the object.
• Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck's compressed-air
brakes or a pneumatic drill may af-
fect the function of the system; this
may include reduced performance or
a false activation.
• The sonar system is designed as an
aid to the driver in detecting large
stationary objects to help avoid
damaging the vehicle.
• The sonar system is not designed to
prevent contact with small or moving
objects. Always move slowly. The
system will not detect small objects
below the bumper, and may not de-
tect objects close to the bumper or
on the ground. •
The sonar system may not detect the
following objects: fluff y objects such
as snow, cloth, cotton, glass, wool,
etc.; thin objects such as rope, wire
and chain, etc.; or wedge-shaped
objects.
If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
stacles or false alarms.
CAUTION
• Excessive noise (such as audio sys-
tem volume or an open vehicle win-
dow) will interfere with the tone and
it may not be heard.
• Keep the sonar sensors (located on
the bumper fascias) free from snow,
ice and large accumulations of dirt.
Do not clean the sensors with sharp
objects. If the sensors are covered,
the accuracy of the sonar function
will be diminished.
