I'm getting ready to replace my battery myself on my 2015 GS350 (non F sport). I searched for a DIY on it, but didn't find anything that was good/clear on instructions.
Will I run into any engine/electronic issues? I don't mind losing my radio presets, but more worried about any other electronic gremlins that could occur.

Thanks!

 

It's easy peasy, even my grandma can do it not really. Just lift up on the handle and pull out the old battery. Go to Costco get yourself a Interstate battery, ditch the plastic outer sleeve, you don't need it.
And no, you won't lose any settings at all.

Thanks guys. I've changed batteries before and was just trying to find out if there was anything different or special to do for the GS350 before I did it.

Those instructions look easy, though they do use a battery tender to save the radio settings.

 

No need for a battery tender.
