2019 NISSAN MICRA sensor

Troubleshooting
If you think the front passenger air bag
status light is incorrect:1. If the light is ON with no front passenger and no objects on the front passenger
seat:
This may be due to the following condi-
tions that may be interfering with the
weight sensors: ∙ 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 or between
the seat cushion and the door. 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 ON af ter this, the vehicle
should be checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
2. If the light is ON with an adult occupy- ing the front passenger seat:
∙ Occupant is a small adult — the air bag light is functioning as intended. The
front passenger air bag is suppressed.
However, if the occupant is not a small
adult, then this may be due to the following
conditions that may be interfering with the
weight sensors: ∙ Occupant is not sitting upright, leaning against the seatback, and centered on
the seat cushion with his/her feet com-
fortably extended to the floor. ∙ 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 or between
the seat cushion and the door.
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 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
WARNING
∙ Do not place any objects on the steer-
ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steer-
ing wheel or instrument panel. Such
objects may become dangerous pro-
jectiles and cause injury if the front air
bags inflate.
∙ Immediately af ter inflation, several front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.
∙ No unauthorized changes should be made to any components or wiring of
the supplemental air bag system. This
is to prevent accidental inflation of
the supplemental air bag or damage
to the supplemental air bag system.
∙ Do not make unauthorized changes to your vehicle’s electrical system,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
1-58Safety—Seats, seat belts and supplemental restraint system

∙ 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.

Repair and replacement
procedure
The front air bags, side air bags, curtain air
bags and pretensioner(s) are designed to
inflate on a one-time-only basis. As a re-
minder, unless it is damaged, the supple-
mental air bag warning light remains illu-
minated af ter inflation has occurred. These
systems should be repaired and/or re-
placed as soon as possible. It is recom-
mended that you visit a NISSAN dealer for
this service.
When maintenance work is required on the
vehicle, the front air bags, side air bags,
curtain air bags, pretensioner(s) and re-
lated parts should be pointed out to the
person performing the maintenance. The
ignition switch should always be placed in
the LOCK position when working under the
hood or inside the vehicle.
WARNING
∙ Once a front air bag, side air bag, orcurtain air bag has inflated, the air
bag module will not function again
and must be replaced. Additionally,
the activated pretensioner(s) must
also be replaced. The air bag module
and pretensioner(s) should be re-
placed. It is recommended that you
visit a NISSAN dealer for this service.
However, the air bag module and pre-
tensioner(s) cannot be repaired.
∙ The front air bag, side air bag, curtain air bag systems and the pretensioner
system should be inspected if there is
any damage to the front end or side
portion of the vehicle. It is recom-
mended that you visit a NISSAN dealer
for this service.
∙ If you need to dispose of the supple- mental air bag or pretensioner sys-
tems or scrap the vehicle, it is recom-
mended that you visit a NISSAN
dealer. Incorrect disposal procedures
could cause personal injury. ∙ If there is an impact to your vehicle
from any direction, your Occupant
Classification Sensor (OCS) should be
checked to verif y it is still functioning
correctly. It is recommended that you
visit a NISSAN dealer for this service.
The OCS should be checked even if no
air bags deploy as a result of the im-
pact. Failure to verif y proper OCS
function may result in an improper air
bag deployment resulting in injury or
death.

Door open warning light
This light comes on when any of the doors
are not closed securely while the ignition
switch is placed in the ON position.
Engine oil pressurewarning light
This light warns of low engine oil pressure. If
the light flickers or comes on during nor-
mal driving, pull off the road in a safe area,
stop the engine immediatelyand call a
NISSAN dealer or other authorized repair
shop.
The engine oil pressure warning light is
not designed to indicate a low oil level.
Use the dipstick to check the oil level. For
additional information, refer to “Engine oil”
in the “Do-it-yourself ” section of this
manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost

ered by the NISSAN New Vehicle Limited
Warranty. Turn off the engine as soon as
it is safe to do so.
High temperature warning
light (red)
When the ignition switch is placed in the ON
position, the high temperature warning light
illuminates and then turns off. This indicates
that the high temperature sensor in the en-
gine coolant system is operational.
CAUTION
If the high temperature warning light
illuminates while the engine is running,
it may indicate the engine temperature
is extremely high. Stop the vehicle
safely as soon as possible. If the vehicle
is overheated, continuing vehicle op-
eration may seriously damage the en-
gine. For additional information, refer

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.
When the ignition switch is placed in the ON
position, the power steering warning light
illuminates. Af ter starting the engine, the
power steering warning light turns off. This
indicates the power steering is operational.

nates while the engine is running, it may
indicate the power steering is not function-
ing properly and may need servicing. Have
the power steering checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
2-10Instruments and controls

– When replacing tires, install thespecified 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) in-
cludes 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 not indicate a mal-
function. If the computer senses a mal-
function, 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 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 abov
e5-10km/h (3 -
6 mph). 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.
5-24Starting and driving

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, theindicator 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 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
andindicator lights come
on in the instrument panel. The VDC sys-
tem automatically turns off when these in-
dicator lights are on.
The VDC OFF switch is used to turn off the
VDC system. The
indicator light illu-
minates to indicate the VDC system is off.
When the VDC OFF switch is used to turn off
the system, the VDC system still operates

If you choose to use a tire dressing, take the
following precautions:∙ Use a water-based tire dressing. The coating on the tire dissolves more easily
than with an oil-based tire dressing.
∙ Apply a light coat of tire dressing to help prevent it from entering the tire
tread/grooves (where it would be diffi-
cult to remove).
∙ Wipe off excess tire dressing using a dry towel. Make sure the tire dressing is
completely removed from the tire
tread/grooves.
∙ Allow the tire dressing to dry as recom- mended by the tire dressing manufac-
turer. Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or sof t bristled brush. Wipe
the vinyl and leather (if so equipped) sur-
faces with a clean, sof t cloth dampened in
mild soap solution, then wipe clean with a
dry, sof t cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather (if so equipped).
Before using any fabric protector, read the
manufacturer’s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water to
clean the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifi-
cation sensor. This can also affect the
operation of the air bag system and re-
sult in serious personal injury.
CAUTION
∙ Never use benzine, thinner or any
similar material.
∙ Small dirt particles can be abrasive and damaging to leather (if so
equipped) surfaces and should be re-
moved promptly. Do not use saddle
soap, car waxes, polishes, oils, clean-
ing fluids, solvents, detergents or
ammonia-based cleaners as they
may damage the leather’s natural
finish.
∙ Never use fabric protectors unless recommended by the manufacturer.
∙ Do not use glass or plastic cleaner on meter or gauge lens covers. It may
damage the lens cover.
