Warning!G
Folded second-row seats are intended to
serve as a cargo compartment 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 sec-
ond-row seats as a footrest while driving.
Third-row seat occupants must, like all vehi-
cle occupants, keep both feet on the floor in
front of their seat. Otherwise, occupants
could slide under their seat belt in a colli-
sion. If occupants slide under the belt, it
would apply force at the abdomen or neck.
That could cause serious or even fatal inju-
ries. 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 ma-
neuvers, or an accident and be thrown
around the vehicle interior. Objects thrown
around the vehicle interior may cause an ac-
cident and/or serious personal injury.
!When the second-row seats are folded for-
ward, the front seats may not be moved to the re-
armost position. Otherwise you could damage
the front and second-row seats.
