To use the roof rails as a roof luggage carrier, you must fit t he roof rails
with two or more genuine Toyota cross rails or their equivalent .
When you load cargo on the roof luggage carrier, observe the fo llowing:
●Place the cargo so that its weight is distributed evenly betwee n the
front and rear axles.
●If loading long or wide cargo, n ever exceed the vehicle overall length
or width. ( P. 516)
●Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
●Loading cargo on the roof lugga ge carrier will make the center of grav-

sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failure to operate this vehi cle correctly
and result in death or serious injury.
●If driving for a long distance, on rough roads, or at high spee ds, stop
the vehicle now and then during the trip to make sure the cargo
