If you use a scanner that can read live data, you will see the temperature that the coolant temp sensor is reading and compare that to the cluster reading.
These cluster gauges are not too terribly precise.
With a 185 degree thermostat in both my 2003 and 2004, the actual operating temperature, once the engine is fully warmed up, is around 195-205 degrees.
Both of my cluster gauges will read close to the mid point on the gauge, but an accurate reading is nearly impossible.
With the scanner, you will be able to see where the spot on the cluster gauge is when the thermostat actually opens.
So, with the 185 degree thermostat in your 2013, do not expect the normal operating temp to settle anywhere close to 185.
It will go up and settle somewhere above that.
Once the engine is at full operating temp, take note of the spot on the cluster gauge and there you are.
