To release your seat belt:
Press the release button (1) in the
locking buckle.
When it is released, the belt should
automatically draw back into the
retractor. If this does not happen,
check the belt to be sure it is not twist-
ed, then try again.
Pre-tensioner seat belt
(Driver and front passenger)
OHSS038103
Your vehicle is equipped with driver's
and front passenger's Pre-tensioner
Seat Belts (Retractor Pretensioner
and Emergency Fastening Device
System). The purpose of the pre-ten-
sioner is to make sure the seat belts
fit tightly against the occupant's body
in certain frontal or side collision(s).
The Emergency Fastening Device
System may be activated in certain
crashes where the frontal or side colli-
sion(s) is severe enough, together
with the air bags.
When the vehicle stops suddenly, or
if the occupant tries to lean forward
too quickly, the seat belt retractor will
lock into position. In certain frontal or
side collision(s), the pre-tensioner
will activate and pull the seat belt into
tighter contact against the occu-
pant's body.
(1) Retractor Pretensioner
The purpose of the retractor pre-
tensioner is to make sure that the
shoulder belts fit in tightly against
the occupant's upper body in cer-
tain frontal or side collision(s).
OTL035053
(2) Emergency Fastening Device
System
The purpose of the Emergency
Fastening Device System is to
make sure that the pelvis belts fit
in tightly against the occupant's
lower body in certain frontal or
side collision(s).
If the system senses excessive ten-
sion on the driver or passenger's
seat belt when the pre-tensioner sys-
tem activates, the load limiter inside
the retractor
release some of the pressure on the
affected seat belt.
