Safety features of your vehicle Seat belts
2. After inserting the seat belt,
tighten the belt webbing by pull
-
ing it up.
Pre-tensioner seat belt
Your vehicle is equipped with driver's
and front passenger's pre-tensioner
seat belts (retractor pre-tensioner
and EFD (Emergency Fastening
Device)).
The pre-tensioner seat belts may
be activated, when a frontal collision
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
may lock into position. In certain
frontal collisions, the pre-tensioner
will activate and pull the seat belt
into tighter contact against the
occupant's body.
1. Retractor pre-tensioner
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 collisions.
2. EFD (Emergency Fastening
Device)
The purpose of the EFD is to
make sure that the pelvis belts fit
in tightly against the occupant's
lower body in certain frontal colli
-
sions.
If the system senses excessive ten
-
sion on the driver or passenger's
seat belt when the pre-tensioner
system activates, the load limiter
inside the retractor pre-tensioner
will release some of the pressure on
the affected seat belt.
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.
