The Peugeot 508 HYbrid4 (2012-2016) combines a 2.0 HDi engine at the front with an electric rear-axle motor. This diesel-electric car has the conventional 12 V fuse carriers in two dashboard locations and the engine compartment, but also an approximately 200 V Ni-MH traction system with separate specialist protection. This guide translates all 24 technical positions and 10 common-circuit references in the original tables, without inventing high-voltage fuse numbers or copying the wrong assignments from the standard 508.
Where are the Peugeot 508 HYbrid4 fuse boxes?
Left dashboard: Switch the ignition off and make sure the hybrid READY warning is out. The first 12 V fuse board is behind a lower dashboard hinged service flap on the left-hand side in a left-hand-drive vehicle. Open the hinged panel and ease it past the retaining stops to reach the fuses and service puller. Right-hand-drive access and trim vary, so use the corresponding steering-specific Peugeot instruction.
Behind passenger glovebox: The second cabin electrical group is behind the right-hand dashboard/glovebox area. Open the glovebox and lower or remove its access trim according to the manufacturer so that the F3-F16 positions become visible. This carrier contains the rear seat and boot 12 V outlets, one-touch electric windows, trailer equipment and the audio amplifier; it is not the same physical F6 position as F6 in the left dashboard box.
Engine compartment: Lift the bonnet only after shutting the hybrid system down. The covered main fuse carrier is adjacent to the 12 V battery. Release its lid clips, read the identified positions and reseal the enclosure carefully afterward. Do not disturb orange cables or traction components; Peugeot restricts approximately 200 V system work to trained personnel.
Commonly requested 508 HYbrid4 fuses
This ten-row cross-reference repeats the circuits from the three detailed tables. The same number F6 can refer to different fuse carriers; the description always identifies which box is intended. Not every hybrid saloon is equipped with the rear wiper or panoramic shade found in some other 508 body variants.

Left-hand dashboard fuse carrier
F13 (10 A) protects the front cigarette lighter and F14 (10 A) the separate front 12 V accessory outlet. The radio has two factory alternative 15 A positions, F6 A/B and F28 A/B, rather than a requirement to install both. F8 (3 A) supplies the alarm, F16/F17 (3 A each) the interior lights, and F32 (10 A) the Hi-Fi amplifier on equipped cars. The source also lists F30 (20 A) for a rear wiper, but this applies only if the relevant body has that feature.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| F6 A/B | 15 | Audio system supply, factory alternative A or B physical slot |
| F8 | 3 | Factory alarm controller |
| F13 | 10 | Front cigarette lighter |
| F14 | 10 | Front 12 V accessory power socket |

| F17 | 3 | Front courtesy lamp and illuminated vanity mirror |
| F28 A/B | 15 | Audio system supply, alternative factory A or B slot |
| F30 | 20 | Rear wiper motor if a rear-wiper-equipped body variant uses this position; not an indication of a wiper on every HYbrid4 saloon |
| F32 | 10 | Audio amplifier supply, where fitted |
Fuse panel behind the passenger glovebox
F3 (15 A) supplies the driver window control and rear 12 V outlet, F4 (15 A) the boot 12 V outlet, F5/F6 (30 A each) rear/front one-touch windows, F11 (20 A) trailer electronics and F12 (20 A) the audio amplifier. F16 (5 A) serves the driver window-switch panel. F15 (20 A) is specified for a panoramic-roof blind in SW and related body options; it can remain unused on the HYbrid4 saloon without that equipment.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| F3 | 15 | Driver electric-window switch module and rear-seat 12 V accessory outlet |

Engine-bay fuse box F20-F28 owner-service chart
The factory owner-service table identifies F20 (15 A) for front/rear washer pumps, F21 (20 A) for headlamp washing if fitted, and F22 (15 A) for the horn. F23/F24 (15 A each) protect right/left main beams. F27/F28 (5 A each) serve the corresponding left/right headlamp shutter or mask. These are the seven positions actually included in this owner’s handbook section; omission of other engine-box positions does not prove that they are empty.

How is HYbrid4 different from the standard 508?
HYbrid4 drives the front axle with a 2.0 HDi diesel and the rear axle electrically. A high-voltage Ni-MH traction battery sits toward the rear of the vehicle. Some basic 12 V fuse numbers, outlets, airbags, lights and glass controls match other first-generation Peugeot 508 cars, but the engine electronics, rear drive and voltage-conversion systems are not interchangeable. This guide does not claim that the driver’s dashboard fusebox contains the high-voltage traction battery main fuse.
The orange high-voltage harness, traction battery service disconnect, inverter and motor supply require specialist procedures. Do not remove high-voltage covers, inspect internal battery links or attempt live measurements. Even after READY has gone out, the system may retain dangerous energy and must be handled under the manufacturer’s high-voltage safety process.
Where to check if a 508 HYbrid4 electrical feature fails
Front cigarette lighter dead: Check left dashboard F13 (10 A), then socket contacts. Front 12 V outlet dead: F14 (10 A) is a separate circuit. Rear seat outlet: Behind-glovebox F3 (15 A). Boot power outlet: Behind-glovebox F4 (15 A). If only one socket fails, inspect the socket itself and any damaged plug wiring.
Horn silent: Under-bonnet F22 (15 A); headlamp washers fail: F21 (20 A) if installed. Hi-Fi amplifier not working: Left cabin F32 (10 A) and behind-glovebox F12 (20 A) provide different circuit protections, depending on equipment. One-touch power windows stop: Behind-glovebox F5/F6 (30 A) and door-module wiring.
Hybrid system warning or READY unavailable: First test the ordinary 12 V battery’s condition using standard safe service procedures and read the hybrid module diagnostic codes. No 12 V fuse table can prove that the 200 V traction battery and high-voltage disconnect are safe or healthy. Do not bridge protection devices to make the vehicle start.

The Peugeot 3008 HYbrid4 (2011-2015) has its own F38 traction controller and MF1 vacuum-pump circuits, unlike the 508 dashboard. For a non-hybrid Peugeot 3008 comparison see the 3008 I diesel/petrol fuse tables. The regular 5008 I (2013) uses a separate 12 V battery-distribution system and is not a guide for the 508’s hybrid rear drive.
