Release the seats by pressing down
and sliding forward the locking catch
located on the left and right hand seat
mountings.
With both catches raised, push the
seat unit towards the rear and release
them from the floor anchor points.
The seat can then be lifted out.
The seats must be removed through
the sliding door only.

Removable seats are heavy! Do
not attempt to remove without
assistance.
When installing the seats, ensure
that the seats are properly located
on the anchor points and that the
locking catches are fully engaged.

ensure that the row with the folding
access seat B is positioned
correctly in front of the fixed seat
row A.
If the seats are incorrectly
positioned, access for passengers
is seriously impeded.
