Jeep 2005 Liberty - Manual (Page 46)

Seat Belt Pretensioners
The driver and front passenger seat belts are equipped
with a pretensioning device that is designed to remove
any slack from the seat belt systems in the event of a
collision. This device improves the performance of the
seat belt by assuring that the belt is tight around the
occupant early in a collision. Pretensioners work for all
size occupants, including those in child restraints.
NOTE: These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt must still be
worn snugly and positioned properly.
The pretensioners are triggered by the front Airbag
Control Module. Like the front airbags, the pretensioners
are a single use item. After a collision that is severe
enough to deploy the airbags and pretensioners, they
must be replaced.
Enhanced Driver Seat Belt Use Reminder System
(BeltAlert)
If the driver’s seat belt has not been buckled within 60
seconds of starting the vehicle and if the vehicle speed is
greater than 5 mph (8 km/h), the Enhanced Warning
System (BeltAlert) will alert the driver to buckle their seat
belt. The driver should also instruct all other occupants to
buckle their seat belts. Once the warning is triggered, the
Enhanced Warning System (BeltAlert) will continue to
chime and flash the Seat Belt Warning Light for 96
seconds or until the driver’s seat belt is buckled.
The Enhanced Warning System (BeltAlert) will be reacti-
vated if the driver’s seat belt is unbuckled for more than
10 seconds and the vehicle speed is greater than 5 mph (8
km/h).
