| Item | Figure |
|---|---|
| Headlamps, if equipped | Low beam H11. High beam H9. |
| Premium headlamps | Low and high beam D3S, serviced at an authorized dealer. HID lamps are a high-voltage discharge tube. Do not service an HID bulb yourself. High voltage can remain with the switch off and the key removed. |
| Front lamps | Premium park and turn, premium daytime running lamps, and front fog lamps are LED, serviced at a dealer. Front side marker, if equipped, prints as 7 W5W in the text layer. Premium front side marker is LED. Front park and turn, if equipped, is 7444NA (WY28/8W). |

| Fog-lamp cell | The fog-lamp row says LED, serviced at an authorized dealer. The extracted cell also contains the characters H11 beside that dealer sentence. H11 is already the low-beam row, so it is not treated as the fog bulb. |
