To connect the extender to the seat belt, insert the
tab into the seat belt buckle so that the ªPRESSº
signs on the buckle release buttons of the extender
and the seat belt are both facing outward as shown.
You will hear a click when the tab locks into the buckle.
When releasing the seat belt, press on the buckle
release button on the ext
ender, not on the seat belt. This
helps prevent damage to the vehicle interior and
extender itself.
When not in use, remove the extender and store in the
vehicle for future use.

Front seat belt pretensioners
16E228
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
in 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.

turned to the ªACCº or ªONº position. It goes off
after about 6 seconds. This means the front seat belt
pretensioners are operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, seat belt pretensioner
assemblies, warning light, interconnecting wiring and
power sources. (For details, see ªService reminder
indicators and warning buzzersº on page 60 for

The seat belt pretensioner is controlled by the airbag
sensor assembly. The airbag sensor assembly consists
of a safing sensor and airbag sensor.
When a seat belt pretensioner is activated, an operating
noise may be heard and a small amount of smoke±like
gas may be released. This gas is harmless and does not
indicate that a fire is occurring.
Once the seat belt pretensioner has been activated, the
seat belt retractor remains locked.
