The sequence of the windowbag deployment runs parallel to deployment of the front and rear sidebags and protects the occupants on each side in the event of a side impact in the area of the windows from the A- to the C-pillars against injury.

If the driver sidebag sensor (A53), front passenger sidebag sensor (A54), driver door pressure sensor (B48/7), front passenger door pressure sensor (B48/8), rear door pressure sensor, driver-side (B48/9) and rear door pressure sensor, passenger-side (B48/10) recognize a side impact, then the corresponding acceleration data or pressure values are transmitted to the restraint systems control unit.

If the triggering threshold is exceeded, the restraint systems control unit sends trigger pulses to the corresponding restraint systems.

The following squibs are ignited in the event of a side collision from the left:

driver sidebag squib (R12/9)
left 2nd row sidebag squibR12/11
left windowbag squib (R12/16)

The following squibs are ignited in the event of a side collision from the right:

front passenger sidebag squib (R12/10)
right 2nd row sidebag squib (R12/12)
right windowbag squib (R12/17)

Only with code 494 USA version

In the event of a collision and if the corresponding triggering threshold is exceeded than a signal is sent from the restraint systems control unit to the emergency call system control unit (N123/4) and an automatic emergency call is made.
