Hi,

Those owners with pre-'00 Cars (and maybe a few '00 models) can access actual coolant temp (in °C) through the diagnostic mode of the AC Central Display. To do this, Hold down the Recirculating and Air Up buttons for 5 sec. The + & - buttons will scroll through a list of 'C' codes. The Center Vent button switches between the 'C' code and the actual value. Press Auto to exit the Diagnostics mode. 'C' code - 1c = Oil Temp, 6c = Coolant Temp. Hope this helps...

Happy Motoring!... Jim'99
