Hi maria10102..hope this helps..good luck!!!
The sun canopy is located in the rim of the shell.
• Place the carrying handle in the carrying position.
• Open the rim by pushing the button at the back under the rim and releasing it.
• The sun canopy is now visible in the opening
• Pull it out and place the ends of the sun canopy with the buttonholes over the hooks on the carrying
handle
• When storing the sun canopy, make sure you place it in the rim carefully and close the rim properly
