GENERAL INFORMATION

M25201000001USA0000010000

Driver and passenger’s (front) air bags and seat
belt pre-tensioner deploy and operate in frontal
collisions that exceed the threshold to activate
the SRS (Supplemental Restraint System).

The specific value is the equivalent impact when
a vehicle collides against a concrete (fixed) wall
at approximately 25 km/h (16 mph) or more.

The  front  air  bags  and  pre-tensioner  may  not
work under the following conditions:

A frontal collision is less than the specific
value.

The collision is from the rear

The collision is from the side

The  vehicle  rolls  over  or  is  in  a  similar
position.

The  side-airbags  may  not  work  under  the
following conditions:

The collision is from the front

The collision is from the rear

To provide a better safety upon impact, the driver's
and  front  passenger's  air  bags,  side  air  bags,
curtain  air  bags  and  seat  belts  with  pre-tensioner
have been installed to all the vehicles as standard.

The SRS is a system that is effective with the seat
belt fastened, and it is designed as a supplemental
system of the seat belt.

The advanced air bag system has been adopted to
the  driver's  and  front  passenger's  sides.  When  a
frontal impact exceeds the threshold upon a frontal
collision, or depending on the seat position (driver's
seat side), the air bag inflates the cushion air bag in
two  stages,  improving  the  protection  for  the  front
seat passengers.

The  side-airbag  is  activated  when  an  impact
exceeds the threshold upon a side collision, and the
cushion air bag is instantaneously inflated to protect
the chest area of the front seat passengers.

The curtain air bag is activated simultaneously with
the side-airbag upon a side collision to protect the
heads  of  the  front  seat  and  second  seat
passengers.

All  the  air  bag  modules  are  equipped  with  the
inflator that does not contain toxic sodium azide.

The  seat  belt  pre-tensioner  is  activated
simultaneously with the deployment of driver's and
passenger's  (front)  air  bags  in  case  of  a  frontal
collision.  Seat  belts  are  pulled  in  to  eliminate  the
slack  upon  a  collision,  thus  improving  the  initial
occupant restraint, and reducing the travel distance
of the occupants. For the driver's seat, in addition
to the seat belt pre-tensioner for the shoulder side,
the lap pre-tensioner has been installed on the outer
seat belt lower anchor side in order to improve the
restraining performance in the waist and the chest
areas.

System Component Parts

The SRS consists of six air bag modules, SRS-ECU
(air bag control unit), two front impact sensors, four
side impact sensors, SRS warning light, passenger’s
air  bag  OFF  indicator  light,  passenger’s  seat  belt
warning  light,  clock  spring,  seat  belt  pre-tensioner,
seat  belt  switch,  seat  slide  sensor,  occupant
classification-ECU  and  weight  sensor.  Air  bag
modules  are  located  in  the  center  of  the  steering
wheel  and  above  the  glove  box.  Side-airbags  are
located inside the front seatback assemblies. Each air
bag consists of a folded air bag and an inflator unit.
On all air bag modules, the inflator does not contain
sodium azide. The SRS-ECU placed on the forefront
of the floor monitors the system and has a front air bag
safing G-sensor, front air bag analog G-sensor and a
side-airbag safing G-sensor. The front impact sensor
is  assembled  in  the  front  end  upper  bar  to  monitor
impact  in  case  of  front  impact.  The  side  impact
sensors  inside  the  center  pillars  and  quarter  panel
monitor the shock incurred by the sides of the vehicle.
The  SRS  warning  light  on  the  combination  meter
indicates the operational status of the SRS. The clock
spring is installed in the steering column. The seat belt

pre-tensioner is built into the driver's and passenger's
front  seat  belt  retractor.  The  seat  slide  sensor  is
installed at the seat adjuster section of the driver seat
in order to detect the driver seat slide position. The
weight  sensor  is  installed  underneath  a  rail  of  the
passenger  seat  to  detect  the  load  on  the  seat.  The
passenger’s air bag OFF indicator light is installed to
the lower left of the center panel, and illuminates when
the  passenger’s  (front)  air  bag  is  inactive.  The
passenger’s seat belt warning light is installed to the
lower right of the center panel, and illuminates when
the passenger is not wearing the seat belt. The seat
belt switch detects whether the seat belt is used.
The SRS-ECU will start a squib ignition current to the
driver's/passenger’s (front) air bag module and seat
belt  pre-tensioner  when  simultaneously  detecting
frontal impact with the front impact sensor, front air
bag  safing  G-sensor  and  front  air  bag  analog  G-
sensor. It will also supply a squib ignition current to
the  side-airbag  module  when  simultaneously
detecting side impact with the side impact sensor and
side-airbag safing G-sensor.
