uation:

The front passenger transfers their weight by

supporting themselves on a vehicle armrest.

The front passenger sits in such a way that

their weight is raised from the seat surface.

restraint system when the front passenger

seat is unoccupied

In an accident, the components of the

restraint system may deploy unnecessarily on

the front passenger side if:

There are heavy objects on the front

passenger seat.

The seat belt tongue is engaged in the seat

belt buckle of the front passenger seat and

the front passenger seat is unoccupied.

Stow objects in a suitable place.

Only one person should use each seat

belt at any one time.

Depending on the detected accident situation, the

window airbag on the front passenger side may

deploy. The airbag is deployed regardless of

whether the front passenger seat is occupied.
