2018 NISSAN VERSA sensor

NOTE:
This vehicle’s occupant classification sen-
sor system locks the classification during
driving so it is important that you confirm
that the front passenger is properly clas-
sified prior to driving. Also, the occupant
classification sensor system may recalcu-
late the weight of the occupant when the
vehicle comes to a stop (i.e. stop light, stop
sign, etc.), so front passenger seat occu-
pants should continue to remain seated
as outlined above.
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 2.2 lbs. (1 kg)
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 2.2 lbs. (1 kg)
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.
Safety—Seats, seat belts and supplemental restraint system1-55

∙ 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
∙ Once a front air bag, side air bag, or
curtain 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. It is recommended that you
visit a NISSAN dealer to verif y it is still
functioning correctly. The OCS should
be checked even if no air bags deploy
as a result of the impact. Failure to
verif y proper OCS function may result
in an improper air bag deployment re-
sulting in injury or death.

Instruments and controls2-11

Anti-lock Braking System (ABS) warning
indicator
When the parking brake is released and the
brake fluid level is sufficient, if both the
brake warning light and the ABS warning
light illuminate, it may indicate the ABS is
not functioning properly. Have the brake
system checked and, if necessary, repaired.
It is recommended that you visit a NISSAN
dealer for this service. Avoid high-speed
driving and abrupt braking. For additional
information, refer to “Anti-lock Braking Sys-
tem (ABS) warning light” in this section.
Charge warning light
If this light comes on while the engine is
running, it may indicate the charging sys-
tem is not functioning properly. Turn the
engine off and check the generator belt. If
the belt is loose, broken, missing, or if the
light remains on, have the system checked.
It is recommended that you visit a NISSAN
dealer for this service.
CAUTION
∙ Do not ground electrical accessories
directly to the battery terminal. Doing
so will bypass the variable voltage
control system and the vehicle bat-
tery may not charge completely. For
additional information, refer to “Vari-
able voltage control system” in the
“Do-it-yourself ” section of this
manual.
∙ Do not continue driving if the genera-
tor belt is loose, broken or missing.
Door open warning light
This light comes on when any of the doors
are not closed securely while the ignition
switch is in the ON position.
Engine oil pressure
warning 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 engineimmediatelyand 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
immediately. Such damage is not cov-
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) (if so equipped)
When the ignition switch is placed in the ON
position, the high temperature warning
light illuminates and then turns off. This in-
dicates that the high temperature sensor
in the engine coolant system is opera-
tional.
When driving, the high temperature warn-
ing light may turn off. This indicates that the
engine coolant temperature is within the
normal range.
2-14Instruments and controls

∙ If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull off
the road to a safe location and stop
the vehicle as soon as possible. Driv-
ing with under-inflated tires may per-
manently damage the tires and in-
crease the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and could
result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Infor-
mation label to turn the low tire pres-
sure warning light off. If you have a flat
tire, replace it with a spare tire as soon
as possible. (For additional informa-
tion, refer to “Flat tire” in the “In case of
emergency ” section of this manual.)
∙ When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is
replaced, the TPMS will not function
and the low tire pressure warning
light will flash for approximately1 minute. The light will remain on af ter
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit a NISSAN dealer for this service.
∙ Replacing tires with those not origi-
nally specified by NISSAN could affect
the proper operation of the TPMS.
∙ Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CAUTION
∙ The TPMS may not function properly
when the wheels are equipped with
tire chains or the wheels are buried in
snow.
∙ Do not place metalized film or any
metal parts (antenna, etc.) on the win-
dows. This may cause poor reception
of the signals from the tire pressure
sensors, and the TPMS will not func-
tion properly.Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate.
Some examples are:
∙ Facilities or electric devices using simi-
lar radio frequencies are near the ve-
hicle.
∙ If a transmitter set to similar frequen-
cies is being used in or near the vehicle.
∙ If a computer (or similar equipment) or
a DC/AC converter is being used in or
near the vehicle.
The low tire pressure warning light may
illuminate in the following cases:
∙ If the vehicle is equipped with a wheel
and tire without TPMS.
∙ If the TPMS has been replaced and the
ID has not been registered.
∙ If the wheel is not originally specified by
NISSAN.
Starting and driving5-5

– 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 above3-6mph(5-
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 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.
