brakes NISSAN PATHFINDER 2018 Owner´s Manual

NOTE:
The vehicle’s brake lights come on when
braking is performed by the AEB 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 colli-
sion, should one be unavoidable. If the
driver is handling the steering wheel, accel-
erating or braking, the AEB 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 de- pressed.
∙ When there is no longer a vehicle de- tected ahead.
If the AEB system has stopped the vehicle,
the vehicle will remain at a standstill for
approximately 2 seconds before the
brakes are released.
LSD2766
5-60Starting and driving

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, becareful when braking, accelerating or
downshif ting. Abrupt braking or ac-
celerating 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 as-
sist for the brakes will not work. Brak-
ing 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 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 vehicle in
front of you. Ultimately, the driver is
responsible for safety.
∙ Tire type and condition may also af- fect braking effectiveness.
BRAKE SYSTEM

– When replacing tires, install thespecified 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, refer to “Tire
and Loading Information label” in
the “Technical and consumer infor-
mation” section of this manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself ” section of this manual.
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.
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.
5-74Starting and driving

WARNING
∙ Never rely solely on the hill descentcontrol system to control vehicle
speed when driving on steep downhill
grades. Always drive carefully and at-
tentively when using the hill descent
control system and decelerate the ve-
hicle speed by depressing the brake
pedal if necessary. Be especially care-
ful when driving on frozen, muddy or
extremely steep downhill roads. Fail-
ure to control vehicle speed may re-
sult 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 4WD LOCK switch 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 light is blinking,
the hill descent control is engaged; how-
ever, the hill descent control will not control
the vehicle speed.
∙ Once the system is activated, the indi- cator light will remain on in the instru-
ment panel. For additional information,
refer to “Hill descent control system ON
indicator light” in the “Instruments and
controls” section of this manual.
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 L (Low gear) for engine braking.
WARNING
∙ Never rely solely on the hill start assist system to prevent the vehicle from
moving backward on a hill. Always
drive carefully and attentively. De-
press the brake pedal when the ve-
hicle is stopped on a steep hill. Be es-
pecially careful when stopped on a hill
on frozen or muddy roads. Failure to
prevent the vehicle from rolling back-
wards 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 conditions.
Always be prepared to depress the
brake pedal to prevent the vehicle
from rolling backwards. Failure to do
so may result in a collision or serious
personal injury.
HILL DESCENT CONTROL SYSTEM (if
so equipped) HILL START ASSIST SYSTEM
5-78Starting and driving

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 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.
WARNING
∙ Always turn and look back before backing up. The RSS is not a substi-
tute for proper backing procedures.
∙ Read and understand the limitations of the RSS as contained in this section.
Inclement weather may affect the
function of the RSS; this may include
reduced performance or a false
activation.
∙ This system is not designed to pre- vent contact with small or moving
objects. ∙ The system is designed as an aid to
the driver in detecting large station-
ary objects to help avoid damaging
the vehicle. The system will not detect
small objects below the bumper, and
may not detect objects close to the
bumper or on the ground.
∙ If your vehicle sustains damage to the rear bumper fascia, leaving it mis-
aligned or bent, the sensing zone may
be altered causing inaccurate mea-
surement of obstacles or false alarms.
The RSS sounds a tone to warn the driver of
obstacles near the rear bumper when the
shif t lever is in R (Reverse). The system may
not detect objects at speeds above 3 mph
(5 km/h) and may not detect certain angu-
lar or moving objects.
The RSS detects obstacles up to 5.9 f t
(1.8 m) from the rear bumper with a de-
creased coverage area at the outer cor-
ners of the bumper (refer to the illustration
for approximate zone coverage areas). As
you move closer to the obstacle, the rate of
the tone increases. When the obstacle is
less than 10 in (25.0 cm) away, the tone will
sound continuously. If the RSS detects a
stationary or receding object further than
10 in. (25.0 cm) from the side of the vehicle,

Maintenance and schedules9-3

WARNING
Trailer hitch components have specific
weight ratings. Your vehicle may be ca-
pable of towing a trailer heavier than
the weight rating of the hitch compo-
nents. Never exceed the weight rating
of the hitch components. Doing so can
cause serious personal injury or prop-
erty damage.
Hitch ball
Choose a hitch ball of the proper size and
weight rating for your trailer:∙ The required hitch ball size is stamped on most trailer couplers. Most hitch
balls also have the size printed on the
top of the ball.
∙ Choose the proper class hitch ball based on the trailer weight.
∙ The diameter of the threaded shank of the hitch ball must be matched to the
ball mount hole diameter. The hitch ball
shank should be no more than 1/16”
smaller than the hole in the ball mount. ∙ The threaded shank of the hitch ball
must be long enough to be properly
secured to the ball mount. There should
be at least 2 threads showing beyond
the lock washer and nut.
Ball mount
The hitch ball is attached to the ball mount
and the ball mount is inserted into the
hitch receiver. Choose a proper class ball
mount based on the trailer weight. Addi-
tionally, the ball mount should be chosen to
keep the trailer tongue level with the
ground.
Weight carrying hitches
A weight carrying or “dead weight” ball
mount is one that is designed to carry the
whole amount of tongue weight and gross
weight directly on the ball mount and on
the receiver.
Weight distribution hitch
This type of hitch is also called a “load-
leveling” or “equalizing” hitch. A set of bars
attach to the ball mount and to the trailer
to distribute the tongue weight (hitch
weight) of your trailer. Many vehicles can’t
carry the full tongue weight of a given
trailer, and need some of the tongue weight transferred through the frame and
pushing down on the front wheels. This
gives stability to the tow vehicle.
A weight-distributing hitch system (Class
IV) is recommended if you plan to tow trail-
ers with a maximum weight over 5,000 lbs.
(2,268 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may
affect the operation of trailer surge
brakes. If you are considering use of a
weight-distributing hitch system with a
surge brake-equipped trailer, check with
the surge brake, hitch or trailer manufac-
turer to determine if and how this can be
done.
Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level sur- face. With the ignition on and the doors
closed, allow the vehicle to stand for
several minutes so that it can level.
Technical and consumer information10-23

∙ To reduce the possibility of additionaldamage if your vehicle is struck from
the rear, where practical, remove the
receiver when not in use.
∙ Regularly check that all trailer hitch mounting bolts are securely
mounted.
Tire pressures
∙ When towing a trailer, inflate the
vehicle tires to the recom-
mended cold tire pressure indi-
cated on the Tire and Loading In-
formation label.
∙ Trailer tire condition, size, load rat- ing and proper inflation pressure
should be in accordance with the
trailer and tire manufacturer’s
specifications.
Safety chains
Always use suitable safety chains between
your vehicle and the trailer. The safety
chains should be crossed and should be
attached to the hitch, not to the vehicle
bumper or axle. The safety chains can be
attached to the bumper if the hitch ball is mounted to the bumper. Be sure to leave
enough slack in the chains to permit turn-
ing corners.
Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available
power-type module/converter must be
used to provide power for all trailer
lighting. This unit uses the vehicle bat-
tery as a direct power source for all
trailer lights while using the vehicle tail
light, stop light and turn signal circuits
as a signal source. The
module/converter must draw no more
that 15 milliamps from the stop and tail
lamp circuits. Using a
module/converter that exceeds these
power requirements may damage the
vehicle’s electrical system. See a repu-
table trailer retailer to obtain the proper
equipment and to have it installed.
Trailer lights should comply with federal
and/or local regulations. For assistance in
hooking up trailer lights, it is recommended
that you contact a NISSAN dealer or repu-
table trailer retailer. Vehicles equipped with
the optional trailer tow package are equipped with a 7-pin trailer harness con-
nector. If your trailer is equipped with a flat
4-pin connector, an adapter will be needed
to connect the trailer lights to the vehicle.
Adapters are available at auto parts stores
and hitch retailers.Trailer brakes
When towing a trailer load of 3,500 lbs.
(1,587 kg) or more, trailers with a brake
system MUST be used.
However, most
states require a separate braking system
on trailers with a loaded weight above a
specific amount. Make sure the trailer
meets the local regulations and the regu-
lations where you plan to tow.
Several types of braking systems are avail-
able.
Surge Brakes - The surge brake actuator is
mounted on the trailer tongue with a hy-
draulic line running to each trailer wheel.
Surge brakes are activated by the trailer
pushing against the hitch ball when the
tow vehicle is braking. Hydraulic surge
brakes are common on rental trailers and
some boat trailers. In this type of system,
there is no hydraulic or electric connection
for brake operation between the tow ve-
hicle and the trailer.
