2021 NISSAN VERSA SEDAN brakes

∙ The RAB system may not operate inthe following conditions:
– There is rain, snow, ice, dirt, etc., at- tached to the sonar sensors.
– A loud sound is heard in the area around the vehicle.
– The surface of the obstacle is di- agonal to the rear of the vehicle.
∙ The RAB system may unintentionally 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 vehicle.
– An ultrasonic wave source, such as another vehicle’s sonar, is near the
vehicle. ∙ Once the automatic brake control op-
erates, 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:
– The vehicle is driven in bad weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep hill.
– The vehicle’s posture is changed (e.g., when driving over a bump).
– The vehicle is driven on a slippery road.
– The vehicle is turned sharply by turning the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than NISSAN recommended are used.
– The brakes are cold at low ambient temperatures or immediately af ter
driving has started. – 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.
– Suspension parts other than those designated as Genuine NISSAN
parts are used. (If the vehicle
height or the vehicle body inclina-
tion is changed, the system may
not detect an obstacle correctly.)
∙ Excessive noise (e.g., audio system volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
Starting and driving5-83

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.

– When installing a spare tire, makesure 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
∙ Never rely solely on the hill start assistsystem 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 system may not prevent the vehicle from rolling back-
wards on a hill under all load or road
conditions. Always be prepared to de-
press the brake pedal to prevent the
vehicle from rolling backwards. Fail-
ure to do so may result in a collision or
serious personal injury. When the vehicle is stopped on a hill, the hill
start assist system automatically keeps
the brakes applied to help prevent the ve-
hicle from rolling backward in the time it
takes the driver to release the brake pedal
and apply the accelerator.
The hill start assist system will operate au-
tomatically under the following conditions:
∙ The transmission is shif ted to a forward or reverse gear.
∙ The vehicle is stopped completely on a hill by applying the brake. The maxi-
mum holding time is 2 seconds. Af ter
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 shif t lever is placed in the N (Neu-
tral) or P (Park) position or on a flat and level
road. The RSS sounds a tone to inform the driver
of obstacles near the bumper.
When the “DISPLAY” key is on, the sonar
view will automatically appear in the
touch-screen display. An additional view of
the sonar status will appear in the vehicle
information display for reference.

WARNING
∙ The RSS is a convenience but it is not asubstitute 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 RSS as contained in this section.
The colors of the corner sonar indica-
tor and the distance guide lines in the
rear view indicate 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 performance or a
false activation.
∙ This function is designed as an aid to the driver in detecting large station-
ary objects to help avoid damaging
the vehicle. ∙ The 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 detect objects
close to the bumper or on the ground.
∙ The system may not detect the fol- lowing 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.

If you wax the surface of the hood, be care-
ful not to let wax get into the washer nozzle
D. This may cause clogging or improper
windshield-washer operation. If wax gets
into the nozzle, remove it with a needle or
small pin
C. If the brakes do not operate properly, have
the brakes checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front disc-type brakes self-adjust ev-
ery time the brake pedal is applied. The rear
drum-type brakes self-adjust every time
the parking brake is applied.
