The airbag may feel warm and give off smoke. This is normal. Fold the airbag as follows:
Find the Velcro strap on the left-hand side (4).
Gather the airbag fabric along its length on the left-hand side. Then fold the gathered fabric towards the centre. Wind the Velcro strap (double sided) around as much fabric as possible and fasten it.
Press the rolled up portion of the airbag into the airbag housing (2).
Repeat points 1-3 for the right-hand side. It may be necessary to fold the gathered fabric twice on this side in order to wind the Velcro strap around it.
The airbag housing cover will be open slightly. This is completely normal.
