I am probably being quite dense here but I am very confused about how the heating system in the Niro works. I understand the Air Con setting but how do you heat the car without it? I have tried pressing the Climate Control button and increasing the temperature control but I just get cold air. I find the manual very confusing too! There is also a button which says Heat but what is that for? I basically want to heat the car without the drain of A/C and minimal drain on battery range. Can anyone please give me a straightforward answer? Thanks!
