Hooks
Four hooks, located on the rear compartment trim
panels can be used to secure light weight items
(maximum permissible weight per hook: 9 lbs. [4 kg]).
Partition net (Optional)
Use of the partition net is a particularly important safety
factor when the vehicle is loaded higher than the top of
the seat backrests with smaller objects.
The partition net can be installed behind the backrests
of the front or rear seats.
Note:
Passenger use of seats behind installed partition net is
restricted because of the footwell being taken up by the
net.
