ec switch in mercedes

[mahmooz4]

Hi,

what is the economy mode switch for. Does it turn the a/c on or off and if the red light is on does this mean the ac is off?

Also, what is the best engine oil to use for a c220 cdi on a V plate?

Thanks

with the red eco light on, the air-con is off.......clear hey

Think of it like a standby light on a telly.
