SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

SRS air bag is a system to be effective once

the seat belt is worn. The system is designed

to be a supplemental system of the seat belt.

The system protects head and chest of a front

seat passenger from the frontal collision by

inflating the air bag to soften the impact when

the impact applied from the front of the vehicle

is greater than the set value.

To enhance impact safety, all models are

equipped with driver’s/front passenger’s SRS

air bag as standard.

An inflator that does not contain sodium azide

has been adopted for all types of the air bag

modules.

Seat belt with pre-tensioner featured for the

driver’s and front passenger’s seats is designed

for instantly taking up the slack in the seat

belt at the time of impact to improve restraint

effect on a passenger. It is activated

approximately at the same time as SRS airbag

is activated to improve protection effect on a

passenger.

Caution

Never disassemble the SRS air bag compo-

nents. And never subject the SRS air bag com-

ponents to impact.
