I use the Driving Lights option, via the maxidot display, and check the appropriate box.  Occasionally, the box seems to uncheck itself and the Driving Lights then fail to come on with the ignition.

 

Am I doing something wrong ??

Are you using the same set off keys all the time? Settings are key specific.

I presume you mean the Daylight Running Lights?

 

As has been said you need to programme each key.

(Sorry - Daylight Running Lights)..........Many thanks - I will prog both keys.
