Expanding cargo volume fully
G Warning!
Folded second-row seats are intended to
serve as a cargo volume expansion in
conjunction with folded third-row seats
only. Do not fold the second-row seats and
allow third-row seat occupants to use
folded second-row seats as a footrest while
driving. Third-row seat occupants must, like
all vehicle occupants, keep both feet on the
floor in front of their seat. Otherwise,
occupants could slide under their seat belt
in a collision. If occupants slide under the
seat belt, it would apply force at the
abdomen or neck. That could cause serious
or even fatal injuries. Do not fold the
second-row seats and allow third-row seat
occupants to use folded second-row seats
as a table while driving. Objects placed on
folded second-row seats may come loose
during braking, vehicle maneuvers, or an
accident and be thrown around the vehicle
interior. Objects thrown around the vehicle
interior may cause an accident and/or
serious personal injury.
Folding second-row seats
! When the second-row seats are folded
forward, the front seats may not be moved
to the rearmost position. Otherwise you
could damage the front and second-row
seats.
