Handling a front seat equipped with a side air bag improperly can accidentally operate (deploy) the air bag, which may seriously injure you. Read the service warnings/cautions in the workshop service information before handling the front seat (side air bag integrated).

After assembling the front seat, shake it up and down and verify that the sliding mechanism on the both sides are locked.
