webbing and increase se
at belt performance.
The seat belt pre-tensioner system includes the following components:
The airbag control unit
monitors the readiness
of the electronic parts of the system wheneverthe electric motor switch is in the “ON” or “START” position. Thes
e include all of the
items listed above a
nd all related wiring.
The pre-tensioner seat
belt system will oper-
ate only when the electric motor switch is in the “ON” or “START” position.When the seat belt pre-tensioners activate, some smoke is released
and a loud noise will
be heard. The smoke is
not harmful, but care
should be taken not to in
tentionally inhale it,
as it may cause some
temporary irritation to
people with respiratory problems. The pre-tensioners activa
te in the event of a
moderate-to-severe front
or side impact, even
if the seat belt is not being worn. The seat belt pre-tensioners may not
activate in certain
frontal collisions, even though the vehiclemay appear to be se
verely damaged. Such
non-activation does not mean something is wrong with the seat belt pre-tensioner system,but rather that the collision forces were not severe enough or not of the type to activate the system.

N00407701775
This vehicle is equippe
d with a Supplemental
Restraint System (SRS), which includes air-bags for the driver and passengers. The SRS front airbags are designed to supple- ment the primary protection of the driver and front passenger seat
belt systems by provid-
ing those occupants w
ith protection against
head and chest injuries
in certain moderate to
severe frontal
collisions.
The SRS front airbags, together with sensors at the front of the
vehicle and sensors
attached to the front seats, form an advanced airbag system. The SRS side airbags and the curtain airbags are also designed to supp
lement the seat belts.
The SRS side airbags provide the driver and front passenger with pr
otection against chest,
abdomen and hip injuries by deploying the bag on the side impacted in moderate to severe side impact collisions. The SRS cur-tain airbags provide the driver and passengers on the front seat and rear seat with protection against head injuries by deploying a bag onthe side impacted in m
oderate to severe side
impact collisions. The SRS airbags are NOT a substitute for use of the seat belts. For maximum protection inall types of accident
s, seat belts must
ALWAYS be worn by everyone who drives or rides in this vehicle
(with infants and small
children in an appropriate child restraint sys- tem in the rear seat, and older children buck- led in the rear seat). Re
fer to “Child restraint
systems” on page 4-13.
WA R N I N G Do not attempt to repair or replace any part of the seat belt assemblies. This workshould be done by a certified i-MiEV dealer. Failure to have a certified i-MiEV dealer perform the work could reduce theeffectiveness of the belts and could result in a serious injury or
death in an accident.
Supplemental Restraint Sys- tem (SRS) - airbag
WA R N I N G IT IS VERY IMPORTANT TO ALWAYS WEAR YOUR SEAT BELT PROPERLYEVEN WITH AN AIRBAG.• Seat belts help keep the driver and pas-sengers properly positioned. Thisreduces the risk of injury in all collisions, and reduces the risk of serious injuries or death when the
airbags inflate.
During sudden braking just before a col- lision, an unrestra
ined or
improperly
restrained driver or passengers can moveforward into direct contact with, or within close proximi
ty to, the airbag
when it begins to inflate.The beginning stage of
airbag inflation is
the most forceful and can cause serious injuries or death if the occupant comes incontact with the airbag at this time. • Seat belts reduce the risk of injury inrollovers, rear impact collisions, and in lower-speed frontal collisions, because the airbags are not de
signed to inflate in
those situations.• Seat belts reduce the risk of beingthrown from your vehi
cle in a collision or
rollover.
 IT IS VERY IMPORTANT TO BE PROP- ERLY SEATED.• A driver or front passenger sitting tooclose to the steering wheel or instrument panel during airbag deployment can beseriously injured or killed.

The SRS includes the following components:
The airbag control unit monitors the readiness of the electronic parts of the system wheneverthe electric motor switch is in the “ON” or “START” position. These include all of the items listed above a
nd all related wiring.
The airbags will operate only when the elec- tric motor switch is in the “ON” or “START” position. When the impact sensors detect a sufficient front or side impact to deploy the airbag(s),the appropriate airbag
(s) will be deployed.
WA R N I N GFRONT-FACING CHILD RESTRAINT SYSTEMS should be used in the rear seatwhenever possible. If they must be used in the front passenger seat, move the seat to the most rearward po
sition and make sure
the child stays in the child restraint sys- tem, properly restrained. Failure to follow these instructions could result in seriousinjury or death to the child.Airbag
WA R N I N G Older children should be seated in the rear seat with thei
r seat belt properly
worn, and with an
appropriate booster
seat if needed. Refer to “Children
who have outgrown

When airbags deploy, so
me smoke is released
accompanied by a loud noise. The smoke isnot harmful, but do not intentionally inhale the smoke as it may ca
use temporary irrita-
tion to people with respiratory problems. After deployment, the airbags will quickly deflate, so quickly th
at some people may not
even realize the airbags inflated. Airbag inflation does
not prevent the driver
from seeing or being able
to steer the vehicle,
and does not prevent people from leaving the vehicle.
N00418600227
This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, incertain crash or near crash-like situations, such as an airbag deployment or hitting a road obstacle, data that
will assist in under-
standing how a vehicle’s systems performed. The EDR is designed to
record data related to
vehicle dynamics and sa
fety systems for a
short period of time,
typically 30 seconds or
less. The EDR in this vehicle is designed to record such data as:  How various systems
in your vehicle were
operating;  Whether or not the driver safety belt was buckled/fastened;  How far (if at all) the driver was depress- ing the accelerator and/or brake pedal; and,  How fast the vehicle was traveling.
These data can help provide a better under- standing of the circumstances in which crashes and injuries occur. To read data recorded
by an EDR, special
equipment is required, a
nd access to the vehi-
cle or the EDR is needed. In addition to the vehicle manufacturer, ot
her parties, such as
law enforcement, that have the special equip- ment, can read the information if they have access to the vehicle or the EDR.
N00417900210
The driver’s seat position sensor is attachedto the seat rail and provides the airbag control unit with information on the seat’s fore-aft position. The airbag control unit controlsdeployment of the driver’s front airbag in accordance with the information it receives from this sensor.If there is a problem involving the driver’s seat position sensor, the SRS warning light in the instrument panel will come on. Refer to“SRS warning light” on page 4-26.
CAUTION Airbags inflate very quickly and with great force. In certain situ
ations, contact with an
inflating airbag may cause small cuts, abra- sions, and bruises.
Event Data Recording
NOTE
 EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no dataare recorded by the EDR under normal driv- ing conditions and no
personal data (e.g.,
name, gender, age, and crash location) arerecorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifyingdata routinely acquire
d during a crash inves-
tigation.
Driver’s seat position sensor
WA R N I N G If the SRS warning
light comes on, have
the vehicle inspected by a certified i-MiEV dealer as soon
as possible.
Please observe the following instructions to ensure that the driver’s seat position sensor can operate correctly.• Adjust the seat to the correct position,and sit well back
against the seatback.
Refer to “Front seats” on page 4-3.• Do not recline the seatback more thannecessary when driving.

The indicator normally comes on when the electric motor switch is turned to the “ON” position and goes out a
few seconds later.
In the following situations, the indicator will stay on to show that the passenger’s front air- bag is not operational.  The front passenger’s seat is not occupied.  The system senses that a child is in the child restraint system on the front passen-ger’s seat.
When the passenger’s seat occupant classifi- cation sensor system senses there is a person seated in the front passenger’s seat, the indi-cator goes out to show that the passenger’s front airbag is operational.

There is a Supplemental Restraint System (SRS) warning light on
the instrument panel.
The system checks itself every time the elec- tric motor switch is turned on. The SRS warn- ing light will come on
for several seconds and
then go out. This is normal and means the system is working properly. If there is a prob-
lem involving one or more of the SRS com- ponents, the warning light will come on andstay on. The SRS warning light is shared by the SRS airbag and the seat belt pre-tensioner system.
WA R N I N G If any of the following conditions occur, you should immediat
ely have the airbag
system in your vehicle inspected by a cer-tified i-MiEV dealer as soon as possible:• The passenger’s airbag off indicatorcomes on when an adult is sitting on the front passenger seat.• The passenger’s airbag off indicator doesnot come on when the front passenger’s seat is not occupied.• The passenger’s airbag off indicator doesnot come on when the electric motorswitch is turned to the “ON” position.• The passenger’s airbag off indicatorcomes on and goes out repeatedly.

NOTE
 The warning light may
be illuminated when
the electric motor unit is started while the12V starter battery voltage
is low, but this is
not an ABS malfunction. When the main drive lithium-ion battery is charged, the 12V starte
r battery is charged at
the same time, and the
warning light will go
out. If the warning light does
not go out or illumi-
nates from time to time even after the battery is charged, take your ve
hicle to a certified i-
MiEV dealer and have
the system checked as
soon as possible.  After driving on snow or icy roads, remove any snow and ice whic
h may have been left
around the wheels. On ve
hicles that have an

The tire pressure monitoring system uses tire inflation pressure sensors (A) on the wheels to monitor the tire inflation pressures. The
system only indicates wh
en a tire is signifi-
cantly under-inflated.
 If you continue to press the ASC OFF switch after the ASC is turned off, the “mistakenoperation protection f
unction” will activate
and the ASC will turn back on.
ASC indicator, ASC OFF indi- cator
CAUTION When indicator blinks, the ASC is oper- ating, which means that the road is slippery or that your vehicle’
s wheels are beginning
to slip. If this happens, drive slower.NOTE
CAUTION If an abnormal condition occurs in the sys- tem while driving, the and indicators will illuminate. In these cases, follow these procedures:• Park your vehicle in
a safe place and stop
the electric motor unit. Restart the electric motor unit again and check whether the and indicators go out
. If these indicators
go out, there is no abnormal condition. If the and indicators remain on even after your vehicle is driven a short distance after re-starting the electric motor unit, have the vehicle inspected by a certified i- MiEV dealer as soon as possible.
 When towing the vehicle with only the rear wheels raised off the ground, do not placethe electric motor switch in the “ON” posi- tion. Placing the electric motor switch in the “ON” position could ca
use the ASC to oper-
ate, resulting in an accident. For details, refer to
“Towing” on page 8-12.

NOTE
 The tire pressure monitoring system is not a substitute for regularly
checking tire infla-
tion pressures. Be sure to check the tire inflation pressures as described in “Tires” on page 9-10.
