i hadn't noticed my slip light until this winter, this if my first 4wd that i've owned personally so i'm learning a little.. the slip light only came on when i was playing in 2wd on some iced/snowy roads trying to fishtale.... it let little slips go, but when i got to major slippage it flashed me "put me in 4wd dumbass

"
my dad lovingly refers to all dashboard indicators as "idiot lights"
