release button on the extender, not on the seat belt. This

Front seat belt pretensioners
16G132
The driver and front passenger's seat belt
pretensioners are designed to be activated in
response to a severe frontal impact.
When the airbag sensor detects the shock of a severe
frontal impact, the front seat belt is quickly drawn back
by the retractor so that the belt snugly restrains the front
seat occupants.
The seat belt pretensioners are activated even with no
passenger in the front seat.
Collisions occurring at certain speeds and angles may
cause the seat belt pretensioners and SRS airbags not
to operate all together.
