Check it with a second thermometer if there isn't a calibration procedure in the op manual.

There's a lot of standard deviation with these devices. Look at how you can drive down the street and see a lot of businesses with thermometer readings and they are all different. I would trust your cell phone over all of these sources. Why are you so concerned about the car's reading and demanding absolute accuracy? I'm sorry, but, you're expecting too much, it's not like you're in a hospital surgical room. The outside temperature is a pretty good estimate and I would not get too excited about it. I would pay more attention to my fuel-efficiency and how well the car drives and your overall enjoyment of the car and long term service.

Mark, I am not concerned about 1 or 2 degrees or even 5 or 10 but when I pay cash for an new 2015 car and it is 101 degrees outside and it says 70 something isn't working. I purchased my Subaru Limited with gas efficiency as the number one criteria and it only has 900 miles on it. Not sure where you got the "absolute accuracy" criteria.

rigilsp- yes, sorry, but, it probably would have changed my answer if you had originally stated that your temp gauge was reading 70 degrees when it was 100 degrees outside.

If your car is sitting in traffic or has been sitting in the sun the reading can be off. Once on the road the reading should be +/- 1 degree though. Getting the sensor wet will also cause a low reading.

Subaru like a number of cars have the temperature sensor down low behind the front bumper. While it gets a good flow of air, the air it gets is the air sitting just above the road surface and is naturally hotter. A better location that some Fords have is underneath the outside rear view mirror. Much higher off the ground and more representative of the temperature of the bulk of the air. However, excluding the deviation caused by unrepresentative placement of the sensor, it is inexcusable if the accuracy of the actual sensor is worse than 0.5C.
