SRS AIR BAG SYSTEM
Front Passenger Air Bag Module
INFOID:0000000009466477
The front passenger air bag module is located behind the instrument
panel assembly. It operates with the SRS system in a frontal colli-
sion exceeding a specified level. Refer to
for more information.
Front Side Air Bag
INFOID:0000000009466478
Front side air bag modules are built into the front seatback assem-
blies. Vehicles with side air bags are equipped with labels as shown.
Side Curtain Air Bag
INFOID:0000000009466479
Side curtain air bag modules are located above the vehicle headlining.
Vehicles with side curtain air bags are equipped with labels as
shown.
Front Seat Belt Pre-tensioner
INFOID:0000000009466480
The seat belt pre-tensioner system with load limiter is installed for
both the driver's seat and the front passenger's seat. It operates
simultaneously with the SRS air bag system in the event of a frontal
collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the pre-tensioner. Vehicle passengers are
securely restrained.
When passengers in a vehicle are thrown forward in a collision and
the restraining force of the seat belt exceeds a specified level, the
load limiter permits the specified extension of the seat belt by the
twisting of the ELR shaft, and a relaxation of the chest-area seat belt
web tension while maintaining force.

INFOID:0000000009466482
Occupant Classification System (OCS)
INFOID:0000000009466483
The occupant classification system (OCS) identifies if a child or child
seat is present in the front passenger seat. The OCS receives inputs
from the occupant classification sensor mat (1) which is located
inside the passenger seat cushion assembly. Depending on classifi-
cation of the passenger, the OCS control unit (2) sends a signal to
the air bag diagnosis sensor unit. The air bag diagnosis sensor unit
uses this signal and the seat belt buckle switch RH signal to deter-
mine deployment or non-deployment of the front passenger air bag
module in the event of a collision. Depending on the signals
received, the air bag diagnosis sensor unit can disable the front pas-
senger air bag module completely.
NOTE:
In case of customer concern, CONSULT can be used to confirm the front passenger air bag status (readi-
ness).
