Why does my screen timeout reset itself to 15 seconds everytime I use Android Auto?

[AC Question]

My screen timeout resets itself to 15 seconds everytime I use android Auto

Even if I go into settings and choose keep screen turned on it reverts back to 15 seconds every time I plug it into an android auto certified car stereo. It did not happen with my last phone which was the same brand and running Android 6.0.

Might need to check to see how long you have the "lock screen" set for, regarding auto lock.
