2. Emergency Fastening Device
(EFD)
The Emergency Fastening Device
(EFD) is a supplemental system of
the seat belts. The purpose of the
EFD is to tighten the lap belt against
the occupant's pelvis in certain
frontal collisions.
The pretensioner seat belts may be
activated together with the air bags
upon a severe enough collision.
When the vehicle stops suddenly, or
if the occupant tries to lean forward
too quickly, the seat belt retractor
may lock into position. In certain
frontal collisions (or side collisions),
the pre-tensioner may activate and
pull the seat belt into tighter contact
against the occupant's body.
If the system senses excessive ten-
sion on the driver or passenger's
seat belt when the pre-tensioner acti-
vates, the load limiter inside the
retractor pre-tensioner will release
some of the pressure on the affected
seat belt.

Safety features of your vehicle
Both the driver's and front passen-
ger's pre-tensioner seat belts may be
activated in certain frontal collisions.
The pre-tensioners will not be acti-
vated if the seat belts are not being
worn at the time of the collision.
✽ ✽ NOTICE
When the pre-tensioner seat belts
are activated, a loud noise may be
heard and fine dust, which may
appear to be smoke, may be visible
in the passenger compartment.
These are normal operating condi-
tions and are not hazardous.
WARNING
- Skin irritation
Wash all exposed skin areas
thoroughly after an accident in
which the pre-tensioner seat
belts were activated. The fine
dust from the pre-tensioner
activation may cause skin irrita-
tion and should not be breathed
for prolonged periods.
