REST is designed to heat the car for 20 mins without key. Nice if you run an errrand and leave the gf in the car.
Pressing the DSC has it's own threads. level one, it flashes and turns off TC. level two, hold 30 secs and it turns off TC and shuts down the stability system controls.
most of thus stuff is in the manual, btw. they are only 'hidden' because you aint read it.
the radio button is not, cool feature. the stutter throttle downshift is not as well.
Happy Holidays Everyone!
