WarningG
Folded second-row seats are intended to
serve as 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
second-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 the seat belt in a collision.
If occupants slide under it, the belt 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 ma-
neuvers, or an accident and be thrown
around in the vehicle interior. Objects
thrown around in the vehicle interior may
cause an accident and/or serious personal
injury.
iWhen folding both rows of seats, it is impor-
tant that you fold the second-row seats first, and
then fold the third-row seats.
