2022 TOYOTA SIENNA HYBRID AUX

2174-1. Before driving
4
DrivingCargo capacity depends on the
total weight of the occupants.
(Cargo capacity) = (Total load
capacity) - (Total weight of occu-
pants)
Steps for Determining Correct
Load Limit 
(1) Locate the statement “The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs.” on your
vehicle’s placard.
(2) Determine the combined
weight of the driver and passen-
gers that will be riding in your
vehicle.
(3) Subtract the combined
weight of the driver and passen-
gers from XXX kg or XXX lbs.
(4) The resulting figure equals
the available amount of cargo
and luggage load capacity.
Cargo and luggage

information about storage
precautions, cargo capacity
and load.
WARNING

ried in the luggage compart-
ment

partment:
