on each side of the crossbar.
3. Tighten the tie-down hooks at both sides of the crossbar by turning
clockwise until tight. (A small screwdriver or similar tool can be used to
tighten the hook an additional half turn.)
Be sure to check that the tie-down hooks are tight each time load is
added or removed from the roof rack, and periodically while traveling.
Always ensure that the load is secure before traveling.
Note: Wind noise can be minimized by either removing or repositioning
the crossbars when they are not is use. Position the rear crossbar fully
rearward and the front crossbar 10 inches (25 cm) from the front
end-cap.
