for those of you that use this feature- does it get hot, the after about 10 mins it shuts off? or does it stay on until you turn it off? my seats seem to turn themselves off after about 10mins- not sure if this is a normal feature, or some kinda safety feature...
anyhow- my bro's bmw seats stay hot until you turn it off, so i thought it was kinda weird that the IS3 seats turn off themselves! :-?

anyone got any info?

They warm up, then cool down, then warm up again.
I'm not sure why it was done that way. My guess is for temperature control.

The heated seats that impressed me the most were on LS430, where you can control how hot they get.

yah- hell even in a VW Jetta there's 5 heat control settings!! geez..yet another engineering screw up! issed:

 

[juniorsdad]

yes... the heated seats cycle on and off... sort of built-in thermostat

 

[BugginOuT]

I don't mind the on/off feature @ all.....don't want my ass to be all toasty.

Yeah the point of the heated seat it to get the chill out quick. You don't want to end up with swamp ass.

i use those seats after i go to the gym to give me a nice heated massage til i get in the hot shower! :lol: oh well..guess lexus doesn't want us to use those seats for anything perverse like that! :crazy:

Yeah...the Jetta's heated seats have 5 different settings, but I'd take ours over those.

I like how ours get hot fast then just keep you warm. You've got to mess around too much with the VW's or else you'll get all sweaty. issed:

I figured there was a thermocouple in there that regulated the temp, but maybe its not that sophisticated.

I think our heated seats are pretty bad. Sometimes I can't even tell they are working.

EXACTLY!! this a.m. i had to keep feeling to see if those things were on! :bitching:

I just think they go along with the climate control.

That's probably it.

No, I'm afraid it is much more simple.
Power goes directly into the switch (no relay) and then to the seat.

 

[brc]

there's gotta be a built in thermostat somewhere- connected to a fuse, anyone know how to disable?

I'm afraid it's not that simple.

If its just a simple circuit between the switch - power source - and seat, then why does the temperature vary???

 

[vlad_a]

No, it is that simple.
I assume the temperature varies due to a heat element installed in the seat heater. Pay close attention to where the light is.

The power does go directly to the heater element:

I don't even know it will turn on/off itself well, mine works pretty well.

Or shoot yourself through the roof "Bail out, Goose!"-style.
