I've noticed that when I start my CT on cold days and drive it out of the garage it takes about 3-5 minutes before the auto climate control engages (I typically have the auto temp at 25c). This is not very good since the windows start fogging up and it takes too long for the auto climate control to engage. What I end up having to do is to turn off the auto and turn on the fans manually after about 5 minutes I switch it back to auto at which point the system engages properly.

Has anyone else experienced this problem? I am wondering if the auto system is waiting for the engine to warm up enough so it doesn't blow cold air into the cabin initially? Not good if you need the fan to blow right away to stop the window from fogging up.

Yes same experience and I'm pretty sure the car is waiting to warm up before it starts blowing air into the cabin at force. That said I do find the CT warms up very quick compared to our 2 other vehicles (Ford Escape Hybrid and Kia Sorento). In -5 Celcius weather it starts to blow warm air within 2-3 minutes, our other vehicles are easily double this, the exhaust heat exchange tech seems to be work well :cool:

Thats electric for you! I think you will find that when you stop the car the previous evening you will hear some strange noises coming from under the bonnet (hood), the car pumps some of the warm fluid into a what can only be described as a thermos, this maintains the fluid at a warmer temperature for the next start, meaning when you get in the car the next morning the engine fluid is already at a reasonable temperature and we benefit from it as the car seems to warm up quicker.

As for the auto setting in the morning, this is a feature of Lexus, my IS250 was the same, takes an age for the 'auto' to kick in, so my advice would be to put the blower onto the screen to clear it, by the time you switch it to 'auto' the car will have sufficient warmth.

Hope this helps.

Thanks. My initial thoughts have been confirmed.

That's normal for an Auto Temp system. It will blow right way if you set it to defrost, but the heat will come on when the water temp reaches operating temp.

i use remote start. i let the car warm up for ~5 minutes and it is pretty warm by the time i enter the car. this is in ~30 F (-1 Celsius) morning weather.

The last 4 cars I've owned have all had automatic climate control. The climate control never comes on until the engine is warm.

If windshield frosting is a problem, you can manually turn on the front windshild defroster. Just be prepared for a blast of cold air in the face. :p

Well it seems as this was already answered, but does anyone else find it odd that there's no engine temp gauge on the dash? This is my first car that I've owned that doesn't have this.

I find it odd that's there no engine temperature gauge as well. I wonder what the logic is behind not having one?

My wifes Toyota Yaris does not have a temperature gauge, it just shows a green thermomenter symbol when the engine is cold, and if the engine overheats you get a red thermometer symbol, and then probably steam coming out from under the bonnet (hood)! It seems common place now for cars not to have a temperature gauge.

Maybe they're getting more confident that their products won't overheat?

I agree that not having a coolant temperature gauge is disappointing. I use a scan gauge to display it. It actually does take quite a few minutes to heat up to normal driving temperatures. Heat isn't a strength of this car.

Do you have a pic of what you use/how it reads? Thanks.

Here's a picture of the scan gauge. Lower left is coolant temperature. Upper left is state of battery charge. Upper right is motor torque. Lower right is wattage of air conditioner. Gauge plugs into OBD port. It's a very versatile device.

Very interesting! Thanks for sharing.
