Flipping the bench up (from the driver's side):
1. Ensure all backrests are folded down, and all headrests are in the
lowered position.
2. Locate the black release strap and pull it in the rearward direction
to release the rear latches.
3. Slowly pivot the bench about the front anchorages until it stops.
Flipping the bench down (from the driver's side):
1. Using a generous amount of force, pivot the rear of the bench
downward until the rear latches engage with the hooks in the floor.
If one or both latches fail to engage, pull the black release lever at
the side of the bench and pivot it downward once again with more
force. If difficulties arise, contact Savaria® Vehicle Group.
2. Flip the backrests and headrests up.
For removal and installation, see section 4.1.3 as well as the instructions
above for flipping this bench up/down.
