#28 of 47 Ambient Temperature Gauge by nissmazlover Jun 29, 2006 (10:03 am)
Hi,     Just have a question for you all: How accurate do you think your Ambient Temperature Gauge is on your Mazda 5? Do you think it accruately tells you what the temperature is outside?     I ask this because when I first got the car, I noticed that the gauge was ALWAYS spot on! (I would see the temp displayed and then I would hear the weather on the radio and it was always the same figure or very close to it) Nowadays, though, I noticed that it displays a higher temperature than what it actually feels like outside and higher than what is said by the radio weather forecasts. I chalk it up to it being summer and very hot and the varying degrees of temperature throughout the NYC area, but I still wonder if the gauge has lost its accuracy. Please advise. Thanks!

Replying to: nissmazlover (Jun 29, 2006 10:03 am) It's probably OK to relax on this one. You're probably just letting the laws of physics bug you too much. The standard means of reporting the temperature in weather reports is air temperature measured in the shade. When skies are clear, metal objects and the earth itself absorb more radiation from the sun than the air does, thus they reach higher temperatures than the air. The more still the air, the more so. This is why parked-car interiors reach such high temperatures in the summer. At night, the reverse happens, metal and earth radiate more to the night skies, and reach lower temperatures than the air. Thus, dew or frost. Both these mechanisms are inhibited by clouds. Bottom line, it would be very difficult to get an automobile-mounted ambient temperature sensor to read the same temperature as the Weather Service reports, when the car has been parked, especially in sunny summer weather. Remember, Mazda also had to consider how to avoid sensing the high temps of the engine compartment, and the hot asphalt. I'm pretty impressed with the ambient readings I get in our 5. Just wait a while after you start driving, then see what it says.
#31 of 47 Heat always on by zzoomguy Sep 26, 2007 (6:39 am)
I have a Touring Model with the climate control. It seems like the heater is always on: even if I turn the temperature all the way down, if I don't have the AC on, the air coming out the vents is almost 20 degrees F warmer than the ambient air.   Has anyone else experienced this?   So far no luck with the dealership on this problem, by the way.

Replying to: zzoomguy (Sep 26, 2007 6:39 am) Is this true even in the winter? Replies to this message: zzoomguy (Sep 27, 2007 5:29 am)

Replying to: bobw3 (Sep 26, 2007 9:08 am) I haven't actually done any measurements in the winter, I must admit. The measurements I've done are when it is in the 70's out. It is most noticeable then, as AC really shouldn't be necessary, and all you want is some fresh air.
#35 of 47 AC Performance by kivo Jan 22, 2008 (2:01 pm)
How does the car run when the AC is on? Does it still run smoothly? Any change at all in power? I drive a 6 cyl. now so I just want to make sure the car runs well when the AC is on. Thanks. Replies to this message: coolmazda5 (Jan 23, 2008 8:45 pm)

Replying to: kivo (Jan 22, 2008 2:01 pm) I have driven 4,6 and 8 Cyl. A/C load is felt in 6 and 4 so yes, there is a minor change in load but so far power remains OK. before my Mazda5s (I have one with the "regular" A/C knobs and one with the Auto A/C one) I had a Honda Civic and, compared to the Mazda5, it felt really "loaded" with A/C
#37 of 47 2008 Mazda5 A/C by kivo Jun 09, 2008 (12:46 pm)
Went out today in close to 100 degree heat and I felt the A/C was not as cold as my last car. I have a 2008 Touring and although it wasn't hot in the car, I think it should have been cooler. I know there were complaints about the A/C, but I thought they would have fixed it by now. Anyone else who owns a 2008 have this problem?
