Brake NISSAN SENTRA 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.

AEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the AEB system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The AEB system cannot detect all ve- hicles under all conditions.
∙ The radar sensor does not detect the following objects:
– Pedestrians, animals or obstacles in the roadway.
– Oncoming vehicles.
– Crossing vehicles.
∙ The radar sensor has some perfor- mance limitations. If a stationary ve-
hicle is in the vehicle’s path, the AEB
system will not function when the ve-
hicle is driven at speeds over approxi-
mately 50 mph (80 km/h).
∙
The radar sensor may not detect a ve-
hicle ahead in the following conditions:
– Dirt, ice, snow or other material covering the radar sensor. – Interference by other radar
sources.
– Snow or road spray from traveling vehicles.
– If the vehicle ahead is narrow (e.g., motorcycle).
– When driving on a steep downhill slope or roads with sharp curves.
∙
In some road or traffic conditions, the
AEB system may unexpectedly apply
partial braking. When acceleration is
necessary, continue to depress the ac-
celerator pedal to override the system.
∙ Braking distances increase on slip- pery surfaces.
∙
The system is designed to automatically
check the sensor’s functionality, within
certain limitations. The system may not
detect some forms of obstructions of
the sensor area such as ice, snow, stick-
ers, etc. In these cases, the system may
not be able to warn the driver properly.
Be sure that you check, clean and clear
the sensor area regularly.
∙ Excessive noise will interfere with the warning chime sound, and the chime
may not be heard.

During the first 1,200 miles (2,000 km),
follow these recommendations to ob-
tain maximum engine performance
and ensure the future reliability and
economy of your new vehicle. Failure to
follow these recommendations may re-
sult in shortened engine life and re-
duced engine performance.
∙ Avoid driving for long periods at con- stant speed, either fast or slow, and do
not run the engine over 4,000 RPM.
∙ Do not accelerate at full throttle in any gear.
∙ Avoid quick starts.
∙ Avoid hard braking as much as pos- sible.
∙ Do not tow a trailer for the first 500 miles (805 kilometers). Your engine, axle or
other parts could be damaged. Follow these easy-to-use Fuel Efficient
Driving Tips to help you achieve the most
fuel economy from your vehicle.
1. Use Smooth Accelerator and Brake
Pedal Application
∙ Avoid rapid starts and stops
∙ Use smooth, gentle accelerator and brake application whenever possible
∙ Maintain constant speed while com- muting and coast whenever possible
2. Maintain Constant Speed
∙ Look ahead to try and anticipate and minimize stops
∙ Synchronizing your speed with traffic lights allows you to reduce your num-
ber of stops
∙ Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
∙ Below 40 mph (64 km/h), it is more efficient to open windows to cool the
vehicle due to reduced engine load
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS
5-68Starting and driving

∙ Keep your engine tuned up.
∙ Follow the recommended scheduledmaintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases
tire wear and lowers fuel economy.
∙ Keep the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer
information” section of this manual.
WARNING
∙ Do not stop or park the vehicle overflammable 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 in P (Park) for
Continuously Variable Transmission
(CVT) models or in an appropriate
gear for manual transmission (M/T)
models. Failure to do so could cause
the vehicle to move unexpectedly or
roll away and result in an accident.
Make sure the shif t lever has been
pushed as far forward as it can go and
cannot be moved without depressing
the foot brake pedal.

INCREASING FUEL ECONOMY PARKING/PARKING ON HILLS
5-70Starting and driving

∙ Never leave the engine running whilethe vehicle is unattended.
∙ To help avoid risk of injury or death through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require the
assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
1. Firmly apply the parking brake.
2. M/T models
Place the shif t lever in the R (Reverse)
position. When parking on an uphill
grade, place the shif t lever in 1st gear.
CVT models
Move the shif t lever into 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
1:
Turn the wheels into the curb and
move the vehicle forward until the curb
side wheel gently touches the curb.
∙ HEADED UPHILL WITH CURB
2:
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
3:
Turn the wheels toward the side of the
road so the vehicle will move away
from the center of the road if it moves.
4. Place the ignition switch in the LOCK position and remove the key.
WARNING
∙ If the engine is not running or isturned off while driving, the power as-
sist for the steering will not work.
Steering will be harder to operate.
∙ When the power steering warning light illuminates with the engine run-
ning, there will be no power assist for
the steering. You will still have control
of the vehicle, but the steering will be
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
The power steering system is designed to
provide power assist while driving to oper-
ate the steering wheel with light force.
When the steering wheel is operated re-
peatedly or continuously while parking or
driving at a very low speed, the power as-
sist for the steering wheel will be reduced.
This is to prevent overheating of the power
steering system and protect it from getting
damaged. While the power assist is re-
duced, steering wheel operation will be-
come heavy. When the temperature of the
power steering system goes down, the
power assist level will return to normal.
Avoid repeating such steering wheel op-

erations that could cause the power steer-
ing system to overheat.
You may hear a noise when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the power steering system is not
functioning properly and may need servic-
ing. Have the power steering system
checked. It is recommended that you visit a
NISSAN dealer for this service.
When the power steering warning light illu-
minates with the engine running, there will
be no power assist for the steering, but you
will still have control of the vehicle. At this
time, greater steering effort is required to
operate the steering wheel, especially in
sharp turns and at low speeds.
For additional information, refer to “Power
steering warning light” in the “Instruments
and controls” section of this manual.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, 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.
BRAKE SYSTEM
5-72Starting and driving

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, butit 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.
– 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, 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) 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 for-
ward 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 illuminates the ABS warning
light on the instrument panel. The brake sys-
tem then operates normally, but without
anti-lock assistance.
Starting and driving5-73

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 vehicle at
all times. 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 output to reduce drive wheel slip based
on vehicle speed (traction control func-
tion).
∙ 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 fol- low the steered path despite in-
creased 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
5-74Starting and driving

When the VDC system operates, theindicator in the instrument panel flashes to
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 indi-
cates that the VDC system is working
properly.
∙ Adjust your speed and driving to the road conditions.
For additional information, refer to “Slip in-
dicator light” and ”Vehicle Dynamic Control
(VDC) OFF indicator light” in the ”Instru-
ments and controls” section of this manual.
If a malfunction occurs in the system,
the
indicator light comes on in the
instrument panel. The VDC system auto-
matically turns off when the indicator light
is off.
The VDC OFF switch is used to turn off the
VDC system. The
indicator and the
AEB system warning light illuminates to in-
dicate 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
indicator flashes if this oc-
curs. 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 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 driving and
cornering on slippery surfaces and al-
ways 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 deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, 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 ex-
tremely deteriorated, the VDC system
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.
Starting and driving5-75

∙ When driving on extremely inclinedsurfaces such as higher banked cor-
ners, the VDC system may not operate
properly 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 illumi-
nate. This is not a malfunction. Re-
start 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 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.
RISE-UP AND BUILD-UP
The system gradually adjusts braking
power during normal braking to help pro-
vide an enhanced brake feel.
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 helpthe 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 driving and
cornering on slippery surfaces and al-
ways drive carefully. ∙ Do not modif y the vehicle’s suspen-
sion. If suspension parts such as
