GENERAL INFORMATION

The SRS* air bag is a system that is effective with the seat belt fastened, and it is designed as a supplemental system of the seat belt.
To provide a better safety upon impact, the driver’s and passenger’s (front) air bags and driver’s knee air bag have been installed to all the vehicles as standard equipment. In addition, the side-airbag and curtain air bag have been adopted as an option.
The seat belts with pre-tensioner are now available as standard equipment for all models.
The dual stage air bag has been adopted to the driver’s and passenger’s (front) sides. When a frontal impact exceeds the threshold upon a frontal collision, or depending on the severity of impact, the air bag inflates the cushion air bag in two stages, improving the protection for the front seat passengers.
The driver’s knee air bag is activated when an impact exceeds the threshold upon a frontal collision, and the cushion air bag is instantaneously inflated for better protection of the driver.
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 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.

caution

Do not disassemble the SRS air bag components or seat belt with pre-tensioner. Also, do not apply an impact.
