1Folding Down the Rear Seats
The rear seat-backs can be folded down to
accommodate bulkier items in the trunk.
Never drive with the seat-back folded down and the
trunk lid open.
2 Exhaust Gas Hazard P. 73
To lock a seat-back upright, push it backwards until it
locks.
When returning the seat-back to its original position,
push it firmly back. Also, make sure all rear shoulder
belts are positioned in front of the seat-back.
Make sure that the folded seat-back does not press
against the front passenger seat, as this can cause the
weight sensors in the front passenger seat to work
improperly.
2 Passenger Front Airbag Off Indicator P. 58
Make sure all items in the trunk or items
extending through the opening into the rear
seats are properly secured. Loose items can fly
forward if you have to brake hard.
The front seat(s) must be far enough forward so they
do not interfere with the rear seats as they fold
down.
