Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Outside Temperature
The outside temperature gauge is integrated in the display in the tachometer. This function displays the outside temperature. If there is a risk of icy road conditions, a snow flake symbol is displayed to warn the driver. A snowflake is displayed between -5 to +2 °C.
A sensor which detects the outside temperature is mounted in the left-hand door mirror (6/62). The temperature sensor is directly connected to the engine control module (ECM) (4/46) which then forwards the signal to the driver information module (DIM) (5/1). The temperature is displayed in Celsius or Fahrenheit, depending on the market, in increments of one degree. The unit for temperature display is a programmable customer parameter.
