Install the rear crossbar in the same manner as the
front crossbar.
NOTE
The rear crossbar should be positioned just in
front of the rear seam (joint) between the rear roof
rail support and the roof rail.
Do not carry cargo on the roof when the cross-
bars are removed. Luggage on the roof will be
thrown forward or backward in sudden stops or
rapid accelerations, resulting in a dangerous
road hazard.
NOTE
Before each use of the roof crossbar, make sure
the four T-30 crossbar clamp screws have been
checked, and retightened if necessary to 35 inch
lbs. (4.0 N-m, 0.41 kg-m), as outlined in Step #5
above.
