Advanced Head Protection System (AHPS2)
The head airbag, known as the Advanced Head Protection System (AHPS2) offers the vehicle occupants in the front and rear additional protection from impacts. The airbag is located behind the interior trim above the door and rear side glass. The igniter/gas generators are fixed to the body rear inner side panels in the luggage compartment. The airbag itself is tethered to the body by two securing straps and bolts, one at the A post, the other on the C post. In between the two tether points, the airbag is held in place with six plastic clips, which are designed to break apart as the airbag inflates. The center portion of the folded airbag is retained on a metal bracket which itself is secured to the body by two bolts and located at the top of the B post.
The 15 liter head airbag is filled with nitrogen/argon gas from a pressurized chamber and remains inflated slightly longer than conventional airbags, this is to provide additional head protection in the event of a secondary impact.
To disconnect the vehicle harness lead from the gas generator, lift the locking cap of the connector to unlatch and then pull the connector away from the module. Do not pull on the harness lead. When reconnecting, ensure the connector is fully mated in the socket of the airbag module then press the hinged locking cap into place to secure the connector in position.
