SRS AIR BAG SYSTEM
Front Passenger Air Bag Module
INFOID:0000000001396422
The front passenger air bag module is single stage and located
behind the instrument panel assembly (mounted to the steering
member). It operates with the SRS system in a frontal collision
exceeding a specified level.
Passenger Air Bag Deactivation Switch
INFOID:0000000001404302
The passenger air bag deactivation switch is located on the RH side
of the instrument panel. The switch can be operated with the ignition
key (models without Intelligent Key) or mechanical key (models with
Intelligent Key). When the switch is turned to th ON positition, the
passenger air bag is enabled and could inflate in a frontal collision.
When the switch is turned to the OFF position, the passenger air bag
is disabled and will not inflate in a frontal collision. After any SRS
repair, make sure the passenger air bag deactivation switch is in the
same position as when the vehicle arrived for service.
NOTE:
In case of customer concern, CONSULT-III can be used to confirm
the passenger air bag status (readiness).

Seat Belt Warning Lamp Control Unit
INFOID:0000000001724663
The seat belt warning lamp control unit is located under the passen-
ger seat. The control unit monitors the status of the driver and pas-
senger seat belt buckle switches as well as vehicle speed. The
control unit uses a timer to turn the driver and passenger seat belt
warning lamps ON and OFF.
Seat Belt Pre-tensioners
INFOID:0000000001396423
The front seat belt pre-tensioners are installed for both the driver's
seat and the front passenger's seat. They operate simultaneously
with the SRS air bag system in the event of a frontal collision with an
impact exceeding a specified level.
The lap seat belt pre-tensioner (2), mounted in the belt anchor posi-
tion, works in conjuction with the front LH or RH seat belt pre-ten-
sioner (1) depending on drive configuration (LHD/RHD).
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-tensioners. 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:0000000001396354
The following SRS components use direct-connect style harness connectors.
• Driver air bag module
• Front passenger air bag module
• LH side curtain air bag module
• RH side curtain air bag module
• Front LH seat belt pre-tensioner
