How does the airbag system operate?

  • Airbags are activated (able to inflate if necessary) only when the ENGINE START/STOP button is in the ON position or approximately within 3 minutes after ignition off.

  • The appropriate airbags inflate instantly in the event of a serious frontal collision or side collision to help protect the occupants from serious physical injury.

  • There is no single speed at which the airbags will inflate. Generally, airbags are designed to inflate based upon the severity of a collision and its direction, etc. Several factors determine whether the sensors produce an electronic deployment/inflation signal.

  • Airbags will not deploy in every crash or collision situations. Airbag deployment depends on several factors including vehicle speed, angles of impact, and, the density and stiffness of the vehicles or objects which your vehicle hits in the collision. The determining factors are not limited to those mentioned above.

  • The front airbags will completely inflate and deflate in an instant. It is virtually impossible for you to see the airbags inflate during an accident. It is much more likely that you will simply see the deflated airbags hanging out of their storage compartments after the collision.

  • In addition to inflating in serious side collisions, side and/or curtain airbags will inflate if the sensing system detects a rollover.

  • When a rollover is detected, side and/or curtain airbags will remain inflated longer. This helps provide protection from ejection, especially when used in conjunction with the seat belts.

  • In order to help provide protection, the airbags must inflate rapidly. The airbag inflates extremely fast between the occupant and the vehicle structures before the occupant impacts the vehicle structures. This speed of inflation reduces the risk of serious or life-threatening injuries and is thus a necessary part of the airbag design. However, airbag inflation can also cause injuries including facial abrasions, bruises and broken bones because the inflation speed also causes the airbags to expand with a great deal of force.

  • There are even circumstances under which contact with the steering wheel or passenger airbag can cause fatal injuries, especially if the occupant is positioned excessively close to the steering wheel or passenger airbag.

WARNING

Airbag inflation

Sit as far back as possible from the steering wheel while still maintaining comfortable control of the vehicle. A distance of at least 10 inches (25 cm) from your chest to the steering wheel is recommended. Failure to do so can result in airbag inflation injuries to the driver.

Noise and smoke

When inflated, the airbags make a loud noise and leave smoke and powder in the air inside the vehicle. This is normal and is a result of the ignition of the airbag inflator. After the airbag inflates, you may feel substantial discomfort in breathing due to the contact of your chest with both the seat belt and the airbag, as well as from breathing the smoke and powder. Open your doors and/or windows as soon as possible after impact in order to reduce discomfort and prevent prolonged exposure to the smoke and powder.

Though smoke and powder are nontoxic, they may cause irritation to the skin (eyes, nose and throat, etc.). If this is the case, wash and rinse with cold water immediately and consult a doctor if the symptom persists.

WARNING

Hot components

Do not touch the airbag storage area's internal components immediately after airbag inflation. The airbag related parts in the steering wheel, instrument panel and the roof rails above the front and rear doors are very hot and can cause burn injuries.

WARNING

Do not install or place any accessories near airbag deployment areas, such as the instrument panel, windows, pillars, and roof rails.

Do not install a child restraint on the front passenger's seat

Never place a rear-facing child restraint in the front passenger's seat.

If the airbag deploys, it would impact the rear-facing child restraint, causing serious or fatal injury.

In addition, do not place front-facing child restraints in the front passenger's seat. If the front passenger airbag inflates, it could cause serious or fatal injuries to the child.

WARNING

Airbag deployment

When children are seated in the rear outboard seats of a vehicle equipped with side and/or curtain airbags, install the CRS as far away from the door side as possible. Inflation of the side and/or curtain airbags could impact the child.
