Dodge 2006 Caravan Owner's Manual page 191

Distribute cargo weight evenly on the roof rack crossbars.
The roof rack does not increase the total load carrying
capacity of the vehicle. Be sure the total load of cargo
inside the vehicle plus that on the external rack does not
exceed the maximum vehicle load capacity.
To move the cross bars, loosen the thumb screws located
at the upper edge of each cross bar approximately six
turns, then move the cross bar to the desired position,
keeping the crossbars parallel to the rack frame. Once the
cross bar is in place, retighten the thumb screws to lock
the cross bar into position.
Attempt to move the crossbar again to ensure that it has
properly locked into position.
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 191
NOTE: To help control wind noise when installing the
cross bars make sure that the arrows marked on the front
side of the cross bars are facing the front of the vehicle.
Also, when the cross bars are not in use the notch on the
cross bars should be aligned with the arrows on the side
rails. This will help reduce the amount of wind noise
when the crossbars are not in use.
The tie down holes on the cross bar ends should always
be used to tie down the load. Check the straps frequently
to be sure that the load remains securely attached.
