Heyy, it's been a while..
When I bought the car, it didn't come with the manual.

My question is; Does Turning OFF -Econ mode- in the climate control system during Winter has any drawbacks such as loosing HP or other??

Also, is there any correlation with car heavily fogging up from the Inside and Econ Mode ON?

 

When you turn econ on it keeps the AC compressor from kicking in, which would make your windows fog up because it's used to dry the air inside.

 

So Turning On EconMode will actually cause Heaving Fogging in my car? Interesting..!
Do we still loose engine power, even in winter??

 

Power loss is almost nonexistent since it's still turning the compressor anyways
