Curious on how they came up with the 105 degree setting? Is that a temp that kids and pets can survive in for extended periods of time? Seems high. I tried to find data on this but came up short.
it does seem kind of high, but I think it's set that high because it's survivable and will not deplete the battery quickly
I'm just glad that children of absent minded parents don't have to die.
Also curious if you can lower the setting (understanding the possible drain on the battery)?
Seems way too high.
Much rather use up some battery than make a pet or child suffer.
This is a Survival feature... the adjustable Comfort version is coming in 8.1
And by having a relatively high 105 deg set point, Tesla can make the claim that it can run for a year on one battery charge since most of the year will be WELL below 105 and the simple venting will reduce the temp sufficiently at a very cost to energy usage.
I wonder how venting works for those of us with the solid roof? It opens the driver's and passenger's windows a crack? Say a half inch? Then if it rains, does it close the windows?
Same question about rain for the panoramic roof. Will it close the pano roof if it detects rain?
@UnshodBob, I believe the venting is through the HVAC system, not windows and roof. AC compressor only turns on if really needed, usually blowing fresh air through vents is enough.
Can someone lock their kids in the car in the hot sun and see :)
Just in case, yes that was sarcasm....
The 12 hour feature of the 8.1 temperature thresholds will be great for car camping. Also nice that the screen stays active for the passenger after the driver leaves.
@JAD - thanks for the clarification. I didn't think of that possibility. Nice not to have to worry about rain coming in through cracked open windows. I used to leave my ICE car windows cracked open at work during hot days, but sometimes it would start pouring (even here in SoCal) and people'd have to run out to close their windows. Being retired, that never happens anymore. :)
105 degrees is the standard setting for hot tubs. Definitely survivable. 8.1 optionality on setting will be better.
Camping mode for the win! (8.1 temp thresholds + screen dimming, etc)
The idea is that if you *forget* the kids or dog in the car, it will prevent massive overheating and possible death of the occupants. And it only works if you are above 20% SOC, too, so it is no guarantee of anything. You still aren't supposed to *intentionally* leave kids or pets in the car. Isn't it illegal most everywhere to do that? Usually when I read about a case like that, it seems like the parent went in somewhere for alcohol or drugs and lost track of the time. That's insane *and* ludicrous! And a tragedy.
If the rain sensor indicator were exposed to the API it would make it possible for applications not only to open or close the roof as they do now, but also to close them in case of rain. Venting the roof by opening it seems like a nice idea, but I don't expect Tesla to risk it just because they can.
Hope it's not illegal to leave my dog in an air conditioned Model S. That would cramp my style.
Someone might break your window to get him out.
Pungoteague_Dave mentioned that "105 degrees is the standard setting for hot tubs." It is also a few degrees cooler than the standard setting under a shade tree in Phoenix in July. I've heard rumors that people lived in Phoenix before air conditioning was common.
That's why I created a sign much to my dismay.
@Bighorn - here's something from the web:
Look up your state. My state, California, has a law. Looks like only about 22 states have a law. I assume children would be better protected than pets, but you never know! :)
I found a site that lists only about 19 states with a law protecting children. So, I guess we *really* love output pets. :)

I've heard rumors that people lived in Phoenix before air conditioning was common.
Why would anyone do that?
I will disable it as soon as I get back to my car seeing how I don't have kids or pets in my car. I don't want my A/C cycling on & off all day to cool the car for no reason. Wear & Tear.
MilesMD88 - i live in the Phienix area, and when I am out in the hot months the inside probably gets up to over 150 degrees. This is probably not good for the interior and it sure is not fun getting into that car when I get back. I realize I could ore-condition the car, and have done that at times, but this feature will be a godsend. I won't have to worry about high interior temps any more.
I agree with MilesMD88. I leave my car at the airport for days at a time while I'm away; sometimes unplugged as it was the past two weeks losing about 1% SOC per day. I don't care to waste more energy or utilize components for no reason. But I think the idea is a great one!
Interior temps over 105 are routine here in Fresno. My car will be running a/c a lot to keep it below that when parked in the sun for much of the year.
For California, the violation is for "Leav[ing] or confin[ing] an animal in any unattended motor vehicle under conditions that endanger the health or well-being of an animal due to heat, cold, lack of adequate ventilation, or lack of food or water, or other circumstances that could reasonably be expected to cause suffering, disability, or death to the animal."
Because of the Tesla's A/C and overtemp protection, there's no endangerment to the ... animal. Obviously, signage to the outside indicating the animal is in no danger is required. Coming back to a broken window and missing pet (due to a bystander thinking you're a torturous lout) would not be fun. Coming back to a dead pet is even more unthinkable.
If you don't want the 105 degree limit, just turn it off in settings and the car is exactly like before. Actually, I believe it starts off, so do nothing and the car will no use extra energy or resources. Only turn it on if you want it to.
Mine defaulted to on.
I turned it off.
Don't know about pets, but the internal mechanisms that regulate our body temperature isn't fully developed in children. Ref: http://www.ncbi.nlm.nih.gov/pubmed/8789564 Any prolonged exposure to 105F is brain damage territory.
@stevenmaifert-thank you. I've been bugged about the hot tub analogy. Younger children should not be sitting in hot tubs, or in a sealed car at 105 degrees. I think most parents who own a Tesla are smart enough to know that.
Like others, I don't know what value this new 105 setting brings to anyone. It won't keep a kid or dog safe, so what exactly is its value? When they allow it to be controllable "soon" in 8.1 then perhaps it will have a use, until then it's pretty useless.
I have trouble why anyone should be thinking that TESLA should now be your babysitter or dog sitter. No one for any reason should think it is OK to leave a child or dog in a car.
We are having a Santa Ana wind in SoCal, car was parked in the sun in 103 degree temps. Must say it was nice getting in a 104 degree car without having to think to use the app to precondition the car. 104 was warm, but not bad and the car cooled to 74 very quickly not being heat soaked at 150 degrees.
Not a life changing feature, but just another of the hundreds of cool touches like auto opening garage door (now with chime!), or self presenting door handles or GPS based suspension height or keyless driving. None are things you can't live without, but they all add up to make a completely unmatched car.
I think 104F comes from 40 degrees in celsus. I grew up in China and 40C was a threshold for business/schools to shut down (in my young ages when there was no A/C).
Wasn't 8.1 supposed to allow us to adjust the threshold temperature? Time to take my car in for service.
i dont think people realize 105 degrees wasn't picked as a temperature to leave your kids in a car. You're not supposed to leave them in period. But its a stop-gap measure to reduce the chances of immediate harm. 160 degrees vs 105 degrees is a no brainer. Tesla could drop the threshold lower but then people would start complaining their batteries are draining so fast.
This isn't a feature designed to let parents leave their kids in their car... Just like AEB, its not meant as a feature to stop you from doing something stupid...just reduce the consequences of you doing something stupid.
It's actually there primarily to protect the electronics in the car. But I agree with post above.
Ditto, especially that beautiful 17" screen.
Seems some were prone to 'leakage', if left in very high temps.
It's 105 every day in summer here in Fresno, people walk around and seem to survive just fine.
Have they rolled out the adjustable temperature for this feature? (not an owner yet)
Bringing this topic back - new owner here (LOVE MY CAR). However, I have the Cabin Overheat Protection turned "ON" yet, I'm sitting at work and see my car is 119 degrees. I just manually flipped on the AC to cool it off, but shouldn't the Cabin Overheat Protection do this for me? Is any one else experiencing this? Is it a bug with the new software update?
The overheat protection should kick in at 105 degs.
Oh and welcome to the family.
@jordanrichard ok, that's what I thought! I have a service request in for another "issue" so I can have them check on this as well. Its not a huge deal since I am monitoring it, but thought that was the whole point of turning it on, thanks for confirming.
And thanks! Love to be apart of the family!
When it does work, it is rather interesting to watch via the app. You can see the interior temperature go 105, 104, 103, 102, 101, 100, 99, 98, 97, 96, 97, 98, 99, 100, 101, 102 etc. It cycles like this all day long.
That's perfect! I have been manually cooling it down to 80 and then it goes up to 110 and then i cool it again... not as efficient, i'm sure.
