Doe anybody know if this 2004 Merc image heats the cab WITHOUT the engine running or key in the ignition.
I know the round dial has aircon at 12 o clock, REST at 6 o clock to heat cab for 30 minutes after engine has just been switched off and booster heater at 9 o clock to heat engine quicker after you start it up.
What does the middle rectangular dial do with the 3 arrows on?
