brake sensor NISSAN QASHQAI 2019 Owner´s Manual

5-104Starting and driving
When driving on some roads, such as
winding, hilly, curved, narrow roads, or
roads which are under construction, the
radar sensor may detect vehicles in a
different lane, or may temporarily not
detect a vehicle traveling ahead. This
may cause the ICC system to decelerate
or accelerate the vehicle.
The detection of vehicles may also be
affected by vehicle operation (steering
maneuver or traveling position in the
lane, etc.) or vehicle condition.
If this occurs, the ICC system may warn
you by blinking the system indicator and
sounding the chime unexpectedly. You
will have to manually control the proper
distance away from the vehicle traveling
ahead.
Automatic cancellation
The following are conditions in which the
ICC system may be temporarily unavail-
able. In these instances, the ICC system
may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead.Condition A:
Under the following conditions, the ICC
system is automatically canceled. A chime
will sound and the system will not be able
to be set:
. Any door is open.
. The driver’s seat belt is not fastened.
. The vehicle ahead is not detected and
your vehicle is traveling below the
speed of 15 MPH (24 km/h).
. Your vehicle has been stopped by the
ICC system for approximately 3 min-
utes or longer.
. The shift lever is not in the D (Drive)
position or manual shift mode.
. The electronic parking brake is ap-
plied.
. The VDC system is turned off.
. The AEB applies harder braking
. VDC (including the traction control
system) operates.
. A wheel slips.
. When distance measurement be-
comes impaired due to adhesion of
dirt or obstruction to the sensor.
. When the radar signal is temporarily
interrupted. Action to take:
When the conditions listed above are no
longer present, turn the system off using
the ProPILOT Assist switch. Turn the
ProPILOT Assist system back on to use
the system.
NOTE:
When the ICC system is canceled under
the following conditions at a standstill,
the electronic parking brake is automa-
tically activated:
.
Any door is open.
. The driver’s seat belt is not fastened.
. Your vehicle has been stopped by
the ICC system for approximately 3
minutes or longer.

Hands on detection
When the Steering assist is activated, it
monitors the driver’s steering wheel op-
eration.
If the steering wheel is not operated or
the driver takes his/her hands off the
steering wheel for a period of time, thewarning (1) appears in the vehicle infor-
mation display.
If the driver does not operate the steering
wheel after the warning has been dis-
played, an audible alert sounds and the
warning flashes in the vehicle information
display, followed by a quick brake appli-
cation to request the driver to takecontrol of the vehicle again.
If the driver still does not respond, the
ProPILOT assist turns on the hazard
flasher and slows the vehicle to a com-
plete stop.
The driver can cancel the deceleration at
any time by steering, braking, accelerat-
ing, or operating the ProPILOT assist
switch.
WARNING
Steering assist is not a system for a
hands-free driving. Always keep your
hands on the steering wheel and
drive your vehicle safely. Failure to
do so could cause a collision result-
ing in serious personal injury or
death.
NOTE:
If the driver lightly touches (instead of
firmly grips) the steering wheel, the
steering torque sensor may not detect
the driver’s hand(s) on the steering
wheel and a sequence of warnings
may occur. When the driver holds and
operates the steering wheel again, the
warnings turn off.

Condition B
In the following conditions, the “Unavail-
able: Front Radar Obstruction” warning
message will appear in the vehicle infor-
mation display.
.The sensor area on the front of the
vehicle is covered with dirt or is
obstructed.
Action to take
If the message appears, stop the vehicle
in a safe place and turn the engine off.

vehicle with a soft cloth, and restart the
engine. If the warning message continues
to illuminate, have the AEB system
checked. It is recommended that you visit
a NISSAN dealer for this service.
. When driving on roads with limited
road structures or buildings (for ex-
ample, long bridges, deserts, snow
fields, driving next to long walls).
Action to take
When the above conditions no longer
exist, the AEB system will resume auto-
matically.

brake pedal is depressed, the
function may not operate or the
start of the operation may be
delayed. The RAB system may
not operate or may not perform
sufficiently due to vehicle condi-
tions, driving conditions, the traf-
fic environment, the weather,
road surface conditions, etc. Do
not wait for the system to oper-
ate. Operate the brake pedal by
yourself as soon as necessary.
. If it is necessary to override RAB
operation, strongly press the ac-
celerator pedal.
. Always check your surroundings
and turn to check what is behind
you before and while backing up.
The RAB system detects station-
ary objects behind the vehicle.
The RAB system does not detect
the following objects:
— Moving objects
— Low objects
— Narrow objects
— Wedge-shaped objects
— Objects close to the bumper
(less than approximately 1 ft
[30 cm]) — Objects that suddenly appear
— Thin objects such as rope,
wire, chain, etc.
. The RAB system may not operate
for the following obstacles:
— Obstacles located high off the
ground
— Obstacles in a position offset from your vehicle
— Obstacles, such as spongy materials or snow, that have
soft outer surfaces and can
easily absorb a sound wave
. The RAB system may not operate
in the following conditions:
— There is rain, snow, ice, dirt,
etc., attached to the sonar
sensors.
— A loud sound is heard in the area around the vehicle.
— The surface of the obstacle is diagonal to the rear of the
vehicle.
. The RAB system may uninten-
tionally operate in the following
conditions:
— There is overgrown grass in
the area around the vehicle. — There is a structure (e.g., a
wall, toll gate equipment, a
narrow tunnel, a parking lot
gate) near the side of the
vehicle.
— There are bumps, protrusions, or manhole covers on the
road surface.
— The vehicle drives through a draped flag or a curtain.
— There is an accumulation of snow or ice behind the vehi-
cle.
— An ultrasonic wave source, such as another vehicle’s so-
nar, is near the vehicle.
. Once the automatic brake control
operates, it does not operate
again if the vehicle approaches
the same obstacle.
. The automatic brake control can
only operate for a short period of
time. Therefore, the driver must
depress the brake pedal.
. In the following situations, the
RAB system may not operate
properly or may not function
sufficiently:

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 de-
vice. 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 dan-
gerous driving techniques. It can
help maintain vehicle control dur-
ing braking on slippery surfaces.
Remember that stopping dis-
tances on slippery surfaces will
be longer than on normal sur- faces 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 Informa-
tion label. See “Tire and Load-
ing Information label” (P.10-
10) of this manual.
— For detailed information, see “Wheels and tires” (P.8-29) of
this manual.
The Anti-lock Braking System (ABS) con-
trols 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 pre- venting 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
distances.
Self-test feature
The ABS includes electronic sensors, elec-
tric 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 malfunc-
tion. If the computer senses a malfunc-
BRAKE ASSIST

tion, 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
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. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.
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 con-
trol 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 condi-
tions).
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 auto-
matically 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 light
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.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-16) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-18).

INTELLIGENT ENGINE BRAKE (Con-
tinuously Variable Transmission
(CVT) models)
The Intelligent Engine Brake function
adds subtle deceleration by controlling
CVT gear ratio, depending on the corner-
ing condition calculated from driver’s
steering input and plural sensors. This
benefit to easier traceability and less
workload of adjusting speed with braking
at corners.
The Intelligent Engine Brake also adds
subtle deceleration with gear ratio con-
trol according to driver’s brake pedal
operation.
The Intelligent Engine Brake can be set to
ON (enabled) or OFF (disabled) through
the Vehicle Information Display “Settings”
page. See “Vehicle information display”
(P.2-19) for more information.
JVS0403X
When the Intelligent Engine Brake is
operated at corners and the “Chassis
Control” mode is selected in the trip
computer, the Intelligent Engine Brake
graphics are shown in the vehicle infor-
mation display. See “Trip computer” (P.2-
39) for more information.
If the chassis control warning message
appears in the vehicle information dis-
play, it may indicate that the Intelligent
Engine Brake is not functioning properly.
Have the system checked as soon as
possible. It is recommended that you visit
a NISSAN dealer for this service.
WARNING
The Intelligent Engine Brake may not
be effective depending on the driv-
ing condition. Always drive carefully
and attentively.
When the Intelligent Engine Brake is
operating, the needle of the tachometer
will rise up and you may hear an engine
noise. This is normal and indicates that
the Intelligent Engine Brake is operating

around and check that it is safe
to do so before parking.
. Read and understand the limita-
tions of the RSS as contained in
this section. The colors of the
sonar indicator and the distance
guide lines in the rear view in-
dicate 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
affect the function of the system;
this may include reduced perfor-
mance or a false activation.
. The RSS is designed as an aid to
the driver in detecting large sta-
tionary objects to help avoid da-
maging the vehicle.
. The RSS is not designed to pre-
vent contact with small or mov-
ing objects. Always move slowly.
The system will not detect small
objects below the bumper, and
may not detect objects close to
the bumper or on the ground.
. The RSS may not detect the
following objects: fluffy 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
system volume or an open vehi-
cle window) will interfere with the
tone and it may not be heard.
. Keep the sonar sensors (located
on the rear bumper fascia) free
from snow, ice and large accu-
mulations of dirt. Do not clean the
sensors with sharp objects. If the
sensors are covered, the accuracy
of the sonar function will be
diminished.
