serious injuries in a collision, as you could slide under the lap belt or be propelled
into the seat belt. Ensure your seat back
is reclined no more than 30 degrees when
the vehicle is moving.
Folding Rear Seats
Model S has a split rear seat that can fold

Note: If Model S is equipped with the optional
executive rear seats, these seats do not fold

Before folding, remove items from the seats
and the rear footwell. To allow the rear seat

Pull the seat back upward until it locks into

are locked in their upright position.
