When using the rear center seat belt, the
buckle with the “CENTER” mark must be
used. To release the seat belt:
The seat belt is released by pressing the
release button (1) of the locking buckle.
When it is released, the belt should auto-
matically draw back into the retractor.
If this does not happen, check the belt to
be sure it is not twisted, then try again.
Pre-tensioner seat belt
Your vehicle is equipped with driver's and
front passenger's pre-tensioner seat
belts. The purpose of the pre-tensioner is
to make sure that the seat belts fit tightly
against the occupant's body in certain
frontal collisions (or side collisions). The
pre-tensioner seat belts may be activated
in crashes, where the frontal collision is
severe enough.
