sensor NISSAN MICRA 2020 Owners Manual

∙ The driver and front passenger seatbelt buckles are equipped with sen-
sors that detect if the seat belts are
fastened. The NISSAN Advanced Air
Bag System monitors the severity of a
collision and seat belt usage, then in-
flates the air bags as needed. Failure
to properly wear seat belts can in-
crease the risk or severity of injury in
an accident.
∙ The front passenger seat is equipped with an occupant classification sen-
sor (weight sensor) that turns the
front passenger air bag OFF under
some conditions. This sensor is only
used in this seat. Failure to be properly
seated and wearing the seat belt can
increase the risk or severity of injury in
an accident. For additional informa-
tion, refer to “Front passenger air bag
and status light” in this section.
∙ Keep hands on the outside of the steering wheel. Placing them inside
the steering wheel rim could increase
the risk that they are injured when the
front air bag inflates.

WARNING
To ensure proper operation of the pas-
senger’s NISSAN Advanced Air Bag Sys-
tem, please observe the following
items.
∙ Do not allow a passenger in the rearseat to push or pull on the seatback
pocket.
∙ Do not place heavy loads heavier than 4 kg (9.1 lbs.) on the seatback, head
restraint/headrest or in the seatback
pocket.
∙ Make sure that there is nothing press- ing against the rear of the seatback,
such as a child restraint installed in
the rear seat or an object stored on
the floor.
∙ Make sure that there is no object placed under the front passenger
seat.
∙ Make sure that there is no object placed between the seat cushion and
center console or between the seat
cushion and the door. ∙ If a forward-facing child restraint is
installed in the front passenger seat,
do not position the front passenger
seat so the child restraint contacts the
instrument panel. If the child restraint
does contact the instrument panel,
the system may determine the seat is
occupied and the passenger air bag
may deploy in a collision. Also the
front passenger air bag status light
may not illuminate. For additional in-
formation, refer to “Child restraints” in
this section.
∙ Confirm the operating condition with the front passenger air bag status
light.
∙ If you notice that the front passenger air bag status light is not operating as
described later in this section, get the
occupant classification system
checked. It is recommended that you
visit a NISSAN dealer for this service.
∙ Until you have confirmed with a dealer that your front passenger seat
occupant classification system is
working properly, position the occu-
pants in the rear seating positions. ∙ Do not position the front passenger
seat so it contacts the rear seat. If the
front seat does contact the rear seat,
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status
light may illuminate and the supple-
mental air bag warning light may
flash.
This vehicle is equipped with the NISSAN
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements
under U.S. regulations. It is also permitted in
Canada. However, all of the information,
cautions and warnings in this manual
still apply and must be followed.
The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The front passenger supplemental
front-impact air bag is mounted in the
dashboard above the glove box. The front
air bags are designed to inflate in higher
severity frontal collisions, although they
may inflate if the forces in another type of
collision are similar to those of a higher
severity frontal impact. They may not in-
flate in certain frontal collisions. Vehicle

If the light is still ON af ter this, the person
should be advised not to ride in the front
passenger seat and the vehicle should be
checked as soon as possible. It is recom-
mended that you visit a NISSAN dealer for
this service.3. If the light is OFF with a small adult, child or child restraint occupying the
front passenger seat.
This may be due to the following con-
ditions that may be interfering with the
weight sensors:
∙ Small adult or child is not sitting upright, leaning against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the floor.
∙ The child restraint is not properly in- stalled, as outlined in the “Child re-
straints” section of this manual.
∙ An object weighing over 4 kg (9.1 lbs.) hanging on the seat or placed in the
seatback pocket.
∙ A child restraint or other object pressing against the rear of the seatback.
∙ A rear passenger pushing or pulling on the back of the front passenger seat. ∙ Forcing the front seat or seatback
against an object on the seat or floor
behind it.
∙ An object placed under the front pas- senger seat.
∙ An object placed between the seat cushion and center console.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Re-
start the vehicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still OFF af ter this, the small
adult, child or child restraint should be re-
positioned in the rear seat and the vehicle
should be checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service. Other supplemental front-impact air
bag precautions

∙ Tampering with the front air bag sys-tem may result in serious personal in-
jury. Tampering includes changes to
the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad and
above the instrument panel or by in-
stalling additional trim material
around the air bag system.
∙ Removing or modif ying the front pas- senger seat may affect the function of
the air bag system and result in seri-
ous personal injury.
∙ Modif ying or tampering with the front passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing ma-
terial on the seat cushion or by install-
ing additional trim material, such as
seat covers, on the seat that are not
specifically designed to assure proper
air bag operation. Additionally, do not
stow any objects under the front pas-
senger seat or the seat cushion and
seatback. Such objects may interfere
with the proper operation of the occu-
pant classification sensor (weight
sensor). ∙ No unauthorized changes should be
made to any components or wiring of
the seat belt system. This may affect
the front air bag system. Tampering
with the seat belt system may result
in serious personal injury.
∙ It is recommended that you visit a NISSAN dealer for work on and around
the front air bag. It is also recom-
mended that you visit a NISSAN dealer
for installation of electrical equip-
ment. The Supplemental Restraint
System (SRS) wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the air bag
system.
∙ A cracked windshield should be re- placed immediately by a qualified re-
pair facility. A cracked windshield
could affect the function of the
supplemental air bag system.
*The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion. When selling your vehicle, we request that
you inform the buyer about the front air
bag system and guide the buyer to the
appropriate sections in this Owner’s
Manual.

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. When the VDC system operates, the
