A Center High-Mounted Stoplamp (CHMSL) is located above the rear window glass. Make sure items loaded on the roof of the vehicle do not block or damage the CHMSL. Rear Seat Armrest Vehicles with a rear seat armrest have two cupholders. Pull the armrest down from the rear seatback to access the cupholders. To adjust a tie-down, pull the locator pin out and move the tie-down to another location making sure the locator pin lines up with a locator hole on the rail. The tie-down pin may not be installed correctly if the pin does not line up, turn it over and reinstall. The tie-down will not move when the pin is completely installed. The maximum load for each rail is 500 lbs (227 kg). The rails are notched at each end which allows the tie-downs to be removed and placed on another rail.
