To replace the bulbs, you need to almost completely remove the front lighting assembly. Lift the retaining clips of the grille and gently pull it away as far as possible, being careful with the connected wires.

Remove the headlamp assembly and carefully pull it out of its housing, first removing the protective cap and then the connector for the electrical wires. Remove the retaining spring of the bulb and gently twist it to take it out. Install the new bulb without touching the glass with your hands.

Refit the two bulb holders in their respective positions and reposition the headlamp assembly in its housing, connecting the relevant connector. When closing, pay attention to the connection of the headlamp washer.
