AirConditioning Trick

I open all my windows and evacuate all the hot air. I'm amazed that people don't do this and drive around in super hot interiors. Good tip thou. I'll try it.

 

It is a good tip. I learned also to open the hatch as soon as I approach the car...it is amazing how much stale hot air is trapped in the boot area.

 

I think we should listen to the guys from Texas and Florida - they know about hot cars.

 

Tint the windows, the Prius is a green house.

 

It doesn't take long to get the hot air out so you don't have to drive long with the windows open. But it makes a big difference.

 

Another trick:

Most are not aware that the A/C-heater control doesn't simply switch from AUTO to manual as soon as the AUTO light turns off. In fact, while in AUTO mode, changing one setting will only make this setting manual, the other settings stays in auto mode (FAN, RECIRC, or MODE).

Therefore, in the case of A/C, you can push AUTO, then manually reduce the fan speed and the system will still automatically control MODE and RECIRC. As the fan speed is slower, the power requirement on the variable speed A/C compressor is reduced. After a few minutes, as the car interior gets cooler, push the AUTO button again to let the system take back control of the fan speed and go back to full auto.

Of course, this routine should first begin with opening all windows for a short period of time to let out hot air (thanks to the full auto electric windows!).

 

Thank you for sharing all of these tips. Some are common sense things that I didn't even think about and others are unique to Prius. I am a bit obsessed with mileage and don't want the a/c (or heater) to eat away at my MPGs.

Also, I am glad to see unapologetic Prius ads back of the airwaves...

 

I tried this on the way home last night and it worked like a charm. I have been putting up with the high speed fan for a while until the cabin cooled down. It was nice to set it to low speed and have the cabin cool down gradually and then switch back to Auto.

THANKS

 

Am I the onlyp one who just drives my Prius like a normal car and if I get 46 MPG in cold weather or 52 in warmer weather, I just don't worry about it?? It is still a lot better than anything as comfortable. I really don;t liek to drive weirdly or be cole in the winter or hot in the summer to eek out an extra mile or two.

As for the window 'trick,' I suggest when you star the car and begin driving, you open one front window only about an inch or two and one back window about the same. That pulls the air out very quickly, keeps it not too breezy and quiet. I suspect that this is also better for gas mileage. I've been doing this for decades.

 

I have a White Prius and I got one of those Sunshades for the front windshield. Even though the white helps keep the car cool, that black dashboard will heat up your car in an instant if you leave your Prius parked in the sun. In seventy degree weather the difference between using the sunshade and not is at least twenty to thirty degrees. Plus it will save your dash board from cracking years from now.

Best part is these windshield sunshades only cost $30 from the Prius shop.

 

I was going to suggest the same thing. I bought a
Heatshield, paid the 30 bucks, use it all the time.
The difference is noticeable. I also think it will
help the dash last longer, too (against cracking
and color fading).

 

I drive mine the same way and get just about the exact same mileage you do. As an added bonus I don't get funny looks from people and I don't get cut off in traffic.

 

Heck, or just get a full body car covering if you must park it in the elements...that's something I'm thinking about.
