Toyota Avanza enhancement - seat locking system

The Toyota Avanza 1.5 provides versatile seat configuration. Both its 2nd row seats are foldable, and of course, its 3rd row seat is also foldable.

It is found that once you fold down the seat, you need to slam it pretty hard to lock the seat back in place. If the seat is not locked back to the car floor properly, it might flip up when you step on the break of the car later.

A simple modification to the seat lock position can enable the car seat to hook back easily to its place. Now, instead of slamming the car seat to lock it in place, you just need to gentlely push it downwards, and it will hook back firmly with a "click" sound.

The trick is to lift the rod of the locking system a little bit higher with washers. You'll need 2 washers to lift each side of the rod. As there are altogether 3 foldable seats, you'll need a total of 6 washers for this modification.



Just unlock and remove the rod from the car floor, put the washer in, put back the rod, and fasten the nut. Then, test the position by locking the car seat.
