In the above vehicles, the display for the outside temperature may change of its own accord.
The temperature on the display unit of the air-conditioning system's control panel (°C/°F, see drawing) may change when the power supply is disconnected. This is caused by a battery that has been discharged, disconnected or replaced previously. The replacement of a fuse may also play a role.
In order to change the ambient temperature unit (°F/°C) on the display back again, proceed as follows:
- Switch on the ignition and wait until the ambient temperature is displayed
- Switch on the radio/audio system
- Press and hold the "Power" button, then press the "Media" button at the same time and hold for 5 seconds
- Release the "Media" button first, then the "Audio" button
- Switch the ignition off and on again
