Booster seat in middle 3rd row of 2013 Toyota Sienna XLE AWD

[llckll]

Hello,

I've been trying to find out of a way to use the 3rd row middle shoulder belt for the booster seat. I purchased a belt extender so my son can click himself in, but the tongue of the belt does not fit the extender. Seems like it's a wider shape than the rest of the seatbelt tongues. Any ideas on how to remedy this?

In the second row, I have my toddler and infant seats.

Hi there,

While it's a great idea, you can't use a seat belt extender with your booster seat. To my knowledge, there aren't any booster manufacturers that allow this.

Is your middle of the 3rd row booster rider the only person in the 3rd row? Can you perhaps explain a little better WHY you want the extender?
