STEP 3
Seat belt pretensioners (front and outside rear seats)
1-4. Adjustable components (seats, mirrors, steering wheel)
Buckle the seat belt and position it
comfortably.
The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal colli-
sion.
The pretensioner may not activate
in the event of a minor frontal
impact, a side impact or a rear
impact.
