2017 NISSAN QASHQAI brakes

5-88Starting and driving
speeds between 6 – 37 MPH (10 – 60 km/h) .
If a risk of a forward collision is detected, the
FEB with pedestrian detection system will firstly
provide the warning to the driver by flashing the
warning (yellow) in the vehicle information dis-
play and providing an audible alert.
If the driver applies the brakes quickly and
forcefully after the warning, and the FEB with
pedestrian detection 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 FEB with
pedestrian detection system issues the second
visual (flashing) (red) and audible warning. If the
driver releases the accelerator pedal, then the
system applies partial braking.
If the risk of a collision becomes imminent, the
FEB with pedestrian detection system applies
harder braking automatically.
While the FEB with pedestrian detection system
is operating, you may hear the sound of brake
operation. This is normal and indicates that the
FEB with pedestrian detection system is oper-
ating properly.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the FEB withpedestrian detection system.
Depending on vehicle speed and distance to the
vehicle or pedestrian 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 be unavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the FEB with pedestrian
detection 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 or
pedestrian detected ahead.
If the FEB with pedestrian detection system has
stopped the vehicle, the vehicle will remain at a
standstill for approximately 2 seconds before the
brakes are released.

BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
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 pressure on the brake pedal will be
required to stop the vehicle and the stopping
distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake pads faster and
reduce gas mileage.
To help reduce brake wear 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.
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.
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
BRAKE SYSTEM BRAKE ASSIST

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.10-10) of
this manual.
— For detailed information, see
“Wheels and tires”(P.8-29) of
this manual.
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 eachwheel 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 notindicate 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 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.

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 toprevent 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 (CVT models) 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
“Vehicle Dynamic Control (VDC) warning light”(P.2-15) .)

It is recommended you contact 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,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.

REAR WINDOW WIPER BLADE BRAKES

Lights*:Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*:When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*:Tires should be rotated every
5,000 miles (8,000 km) .
Tires*:Check the pressure with a gauge often
and always prior to long distance trips. If
necessary, adjust the pressure in all tires,
including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
Tire Pressure Monitoring System (TPMS)
transmitter components:Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Wheel alignment and balance:If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
NISSAN Warranty Information Booklet.
Windshield:Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*:Check for cracks
or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal:Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mat away from the pedal.
Brake pedal:Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer to
stop, have your vehicle checked immediately. It
is recommended you visit a NISSAN dealer for
this service. Keep the floor mat away from the
pedal.Brakes:Check that the brakes do not pull the
vehicle to one side when applied.
Continuously Variable Transmission (CVT)
P (Park) mechanism:On a fairly steep hill,
check that the vehicle is held securely with the
shift lever in the P (Park) position without
applying any brakes.
Parking brake:Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only the
parking brake applied. If the parking brake needs
adjusted, it is recommended you visit a NISSAN
dealer for this service.
Seat belts:Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt
webbing for cuts, fraying, wear or damage.
Seats:Check seat position controls such as
seat adjusters, seatback recliners, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.
Steering wheel:Check for changes in the
steering conditions, such as excessive free play,
hard steering or strange noises.
