SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
D
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.
D
To enhance impact safety, all models are
equipped with driver’s/front passenger’s SRS
air bag as standard.
D
An inflator that does not contain sodium azide
has been adopted for all types of the air bag
modules.
D
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.
