Hi, I think you are referring to your DRLs (Daytime Running Lights). These come on when the engine is started and are a legal requirement on all cars registered after January 2012. However, the law only requires that they be fitted to the car, and does not require you to actually use them. They can be switched off in the Vehicle System settings on the touchscreen. The details of how to do this are in the user's manual (see page 114).
