Hello Today I picked up my 2 year old used Smart (10.000km). Everything is perfect, but I still have a few questions… 1. Is there information about battery voltage, engine (cool water) temperature, oil temperature somewhere? 2. Sometimes the automatic has switched down too early. That does it exactly at speeds in urban traffic of about 50-60kmh. What do you do then? The engine starts to roar because it runs underboard. I don’t want to manually switch down, because the automatic should be used. 3. The tank lock is not locked when the vehicle is closed. Ergo can throw something in. What do you do against it? No matter? The engine makes some sounds unknown to me after longer driving. I don’t know if that’s right. Sounds like a high frequency fast nailing of a diesel engine. But is not always… I have to observe. Smart greeting Thomas
