If your check engine light is on for any reason the auto start feature is disabled. HTH. - Jim

No engine lights on....car has 100k on it and is kept immaculate...auto lock-unlock-panic alarm.......everything that car came with works except autostart!! Apparently there are resistors and diodes in circuit that checks door locks and such before autostart will engage,maybe as simple as one of the door switches are not showing a closed circuit...what do you think????

I bought my 08 300C. After owning it for a few weeks I realized the remote supported auto start. I asked a dealer if my car had it. He checked vin and it did. They ended up reflashing my pc. One of the sensors were outta whack. Can happen just by slamming hood. Ask dealer. Usually a reflash works. I paid $160 Canadian.
