On my Sprinter, there is a ligth on the instrument cluster that looks like an engine. That ligth goes off after the engine starts. Can someone tell me the use of that ligth.

On my Sprinter, With automatic box, as a red switch by the gear lever, that looks like it does not work because I do not see any ligth on the dash board going on and any diference on the car behavour, can sameone inform me about this and a solenoid that is on the ignition switch. The solenoid is disconnected, and if is connected the key does not came out. Any solutions?

It is an 1992 model with 4AFE engine.

I drive a Toyota Sprinter (Japanese MOdel ) engine: AE100 5125309 chassis: 5AB 665600, and I need to know if can run on unleaded petrol.
