Folding and removing rear seats
9 Warning
When rear seats are being folded
or removed, keep hands and feet
away from the moving area.
Never adjust seats while driving as
they could move uncontrollably.
Ensure that the rear seats and
backrests are fully engaged before
occupying the rear seats.
Before folding or removing the rear
seats, ensure that the armrests are
folded away in their most upright
position.
Before folding or removing the rear
seats, first release outboard seat
belts from their buckles and store the
latch plates in their housing.
For the rear centre seat, insert the
latch plate into the buckle 1.
Folding rear seats
On some variants, the load
compartment area can be increased
by folding the 3rd row rear seats
(where fitted).
