3360227 - I04 SIDE LIGHTS / NUMBER PLATE LIGHT AND DIPPED BEAMS DO NOT WORK IN AUTO MODE

The side light/number plate light and dipped beams do not work with the exterior light switch (CLE) on the stalk unit in AUTO position. NB: in AUTO position, the side light/number plate light and dipped beams are turned on automatically by the body computer node that receives a command from the dusk sensor (CPS).CPS sensitivity can be adjusted by means of the 'Mode' control on the lh panel (PCS) and - when the car is at standstill - also via a control on the navigation system (NIT) if fitted. In case of a fault in the dusk sensor and with CLE on AUTO, the body computer node turns on the side light/number plate light and dipped beams regardless.
