Is250 Heating & A/c

[John Edgar]

Just bought a new IS250 SE-L and very lovely it is too. I have one gripe to do with the heating. Is there any way of turning off the cold air that seems always to come out throught the side window vents and the windscreen vents even with the heating set to 22 or 23? It is quite annoying and I would like to get a bit warmer than the system is letting me at the moment.

John,

I think you have the heating on "Auto".

When you notice the cold air, you will see that the display shows arrows showing that the "heat" is not being delivered to your face as well as feet.

What is happening here, is that your car realises that the upper part of the cabin has a temperature higher than the set level and the lower part of the cabin still needs heating (because the hot air rises). So it pumps cold air to the top of the cabin and warm air to your feet for a minute.

There are only two ways to stop it.

1. Don't use the auto mode, so that you can select only your feet.

2. Close those airvents with the slider beside the airvent.

An alternative (which is what I've done) is simply point the vents in a different direction, so the car can manage the temperature like it's trying to do, without me getting a blast of cold air in my face every so often!

I hope that helps!

Thanks a lot and I thought it was something like that. With the vents though, there is no slider on those that blow at the side front windows. They appear to be always open which has seemed to be most of the problem. Also, one last thing. With auto off, does the automatic temperature control still work? In other words, if I switch off auto, and select, say 22, will the system then continue to detect the cabin temperature and hold it all at the selected temperature?

TIA
