Before folding, remove items from the seats
and the rear foot well. To allow the rear seat
backs to fold completely flat, you may need to
move the front seats forward.

Seating and Safety Restraints
Front and Rear Seats
Raising Rear Seats
Before raising a rear seat, make sure that the
seat belts are not trapped behind the
backrest.
Pull the seat back upward until it locks into
place.
To confirm that the seat back is locked in the
upright position, try pulling it forward.
Warning: Always ensure the seat backs
are locked in their upright position.
Failure to do so increases the risk of
injury.
Head Supports
The front seats and outer rear seats include
integrated head supports that are not
adjustable.
The rear center seat includes an adjustable
head support that can be raised, lowered, or
removed. The head support should always be
raised and locked into position (so that the
center is aligned with the center of the ears)
when occupied by a passenger that is not in a
child safety seat.
The head support in the rear center seat
should always be lowered when a seat belt
retained child safety seat is installed. See
Raising/Lowering the Rear Center Head
Support on page 20.
Warning: Ensure that all head supports
are positioned correctly before sitting in,
or operating, Model 3 to minimize the risk
of severe injury or death in the event of a
collision.
