What Air Con Setting?

[jomo]

Ok, so yesterday was as dry as a bucket full o fish and as a result of the cold rain and a warm cabin the front window kept on fogging up! The only way i found to clear said fogging was to flick on the A/C for about 20secs which did the trick.

Is there a better setting on my heater-A/C i should be using to avoid the dreaded fog returning???

[stuie]

leave the a/c on?

[sparkystav]

I'd say leave the AC on all the time,

The petrol usage is negligible if any and it keeps the cabin fresh.

hot or cold you should always have the AC on.

Leaving the A/C on and putting the temp between 22 & 28 with the blowers direction on screen.

Does the job nicely :D

Hi, don't laugh, I'm female and don't know all the proper words, so here goes:

First ensure that all the 'wheels' next to the air vents are up as far as they will go. Then you have the three dials in front of you just to your left; (1) this is the one where you choose where you want the air to go - i.e. straight to the windscreen, to you and the windscreen, just to you, etc, etc. (2) the amount of heat dial, (3) the fan speed dial. Turn (1) all the way round to the last icon at the top of this dial. Turn (2) to its hottest setting (just to start off with and adjust when its warmed up), then make sure that the light lit up on this dial is the one to the right as you look at it from the driver's seat (not the other one, this should be lit up when you aren't using the heater at all). Turn (3) as far as it will go (again, just to start with) and you should visibly see the screen clearing as if by magic. It's normally very fast. If this doesn't happen then there may be something wrong with your system. Hope this helps a bit. :o)

I always find if i am not using the aircon, then i will turn re-circulate air to off, (so its letting fresh air in). That seems to help with steamy windows.

Ok cheers for all the replys regardless of what terminology was use to get you,re message across.

Off to Leyland tonigh so ill have a play with the air con all the time if it dont screw up my MPG's.

[Parthiban]

You should make sure to run the aircon regularly as it lubricates the system - as stav says fuel consumption is negligible but the costs of damage to the A/C system are quite high

i always use he combined feet and screen setting with freash air - never had a problem

[Yeldarb]

Hmmm, my old Saab drank fuel like anything with the air con on, so are you guys saying the lexus system is an "economical" air con????? Most peole say fuel usage is far higher with A/C on????

[Rich OB]

I don't notice much of a difference with fuel consumption with AC on i must say, i don't use it all the time but certainly when its a damp or wet day its set to on, auto, and it keeps the car completely clear. One thing i've found with the IS on wet days without it it fogs up real bad.

just as wozza says and its safer if you can see where your going :)

[Mr. Stig]

Just an idea :

Hold your breath and don't make it worst to blow more moisture on the windows

when driving ..... :lol: :sick:

[DJ Wozza]

lets be honest, the IS200 isn't the most economical car in the first place, better to arrive unflustered & in style

than flustered with a foggy screen :0 (albeit with a touch more petrol)
