On my Mustang you can set the heater & ambient temp to Celsius or Fahrenheit & tyre pressures to kPa or psi. On a couple of occasions
when the battery has been low they have defaulted back to Fahrenheit & kPa. Being an American car I would have expected tyre pressure to go to psi.
You cannot use the tyre pressure indication to check when you pump your tyres as it does not update till you have driven a short way.
