Temp gauge seems to go slightly above middle operating Temp every so often and I know the 2.5 litre engine doesn't have a traditional thermostat but uses a electronically computer controlled valve to Control engine coolant and curious to know if anyone else has noticed the temperature gauge going ever so slightly above every so often and out side temp isn't hot out at 14 degrees C also mine has active grill shutters.

Mine every so often will creep up just ever so slightly.. but nothing to be of major concern but I'm curious to see if others with active grill shutters are getting the same caricistic.

Most auto manufacturers use a dummy gage. Engine temperatures are always changing and most company’s use a range. If it is in that range it sits in the same position. Mazda seems to be much more accurate ... In the winter when I would first start driving. It would slowly increase and when I turned the heat on it would decrease. Because when you turn the heat on you are sucking hot temps from the engine. And after 10 mins it would sit in the middle when at operating temp. The few times I have let her idle for an extended period. It would show right above the half way mark like in your photo.

Good to know , it's my first Mazda and so I'm used to the way the Nissan's would behave as I owned two so good to know this is how the Mazda's are . One thing I really like is how fast the skyactiv engine heats up in the winter and the active grill shutters really seem to help with that in the winter when it's -35 C

I bought a new CX30 in Thailand. Everything I have read says it is possible to change the outdoor temp to fahrenheit. Read all the instructions. Nothing works. Maybe the Asian models are made without this feature? Nothing on the center console works. Nothing in settings works, or even suggests a blinking temp indicator, ready to be changed. Any suggestions?

I have an Ultra Gauge hooked up that gives me a digital coolant temp readout.
It goes as high as 207 F but mostly stays in the 198-202 range.
When it is cool out and not running hard, it stays around 194 F.
I know our turbo is cooled by water so think that may contribute to the higher readings.
It gets up to the 207 on the interstate and cools into the 190's once I exit.

I was referring to outside ambient temperature.

Driving in the cold rain or right now when it's 111 degrees outside (44 Celsius), after the engine warms-up the gauge sits EXACTLY on the 1/2 way line.
