The first-generation Peugeot 508 RXH is a raised estate with distinct hybrid and later diesel-only versions. The original 2012 RXH owner’s handbook gives two interior fuse carriers, one on the lower left dashboard and another behind the passenger glovebox, plus a limited engine fuse list beside the 12 V battery. This guide retains all 22 positions from the original Polish article and restores F27 and F28 (5 A each) from the 2012 Peugeot handbook. Because the original Polish post included three 300 px thumbnails, the diagrams below use larger, matching first-generation Peugeot 508 12 V fuse-carrier drawings already held in the site’s media library.
Where are the Peugeot 508 RXH fuse boxes?
Driver’s lower dashboard: Park the vehicle, switch ignition fully off and on HYbrid4 ensure the READY indicator is extinguished. In left-hand-drive cars open the hinged panel on the left lower dashboard and gently pass the retaining stops to reach the carrier. The factory fuse puller and spare fuses are stored in the glovebox. The RXH owner’s manual labels this section F6 A/B, F8, F13, F14, F16, F17, F28 A/B, F30 and F32.
Behind the passenger glovebox: Open the glovebox, remove the fuse access cover, and look for a second independent F3-F16 carrier. This one powers the rear 12 V outlets, window motors, trailer controller, audio amplifier and panoramic roof blind where fitted. Its F6 for front windows is not the F6 A/B used by the radio in the other dashboard carrier.
Engine bay: Open the bonnet with the vehicle shut down. The sealed electrical unit sits alongside the 12 V battery. Release the lid clips, identify the factory F20-F28 positions and carefully reseal the cover after inspection. These are owner-serviceable 12 V circuits; HYbrid4’s orange high-voltage traction wiring and approximately 200 V battery are not covered by these tables and must not be opened by the vehicle owner.
Which RXH variant is covered?
The original RXH was launched as a 2.0 HDi HYbrid4 with electric rear-axle drive. Later markets also offered non-hybrid diesel RXH versions. The standard 12 V cabin fuse locations are broadly consistent, but powertrain wiring and optional equipment differ. The later 2016 Peugeot handbook expressly associates F15 (20 A) with a panoramic blind in SW and non-hybrid RXH; it must not be assumed occupied on every HYbrid4. The estate’s rear wiper uses F30 (20 A).
Lower-left dashboard fuse box
F13 at 10 A is the front cigarette lighter; a separate F14 10 A protects the front 12 V socket. F6 A/B and F28 A/B at 15 A are manufacturer alternatives for audio equipment, not four fuses that must all be installed. F8 3 A is the alarm, F16/F17 3 A the interior lighting, F30 20 A the rear wiper and F32 10 A the optional amplifier.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| F6 A/B | 15 | Factory audio system supply, location A or B according to installed board |
| F8 | 3 | Alarm system control |
| F13 | 10 | Front cigarette lighter |

| F32 | 10 | Hi-Fi audio amplifier, if equipped |
Additional fuse box behind the glovebox
This carrier supplies F3 15 A for the rear 12 V outlet and driver window panel, F4 15 A for the boot outlet, F5 and F6 30 A for rear and front one-touch window motors, F11 20 A for trailer equipment and F12 20 A for the amplifier. F15 20 A operates the panoramic sunblind when the body and drive version are equipped with it. F16 5 A protects the window switch module.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| F3 | 15 | Driver-side electric window switch panel and rear passenger 12 V socket |
| F4 | 15 | 12 V power outlet in the luggage compartment |

| F11 | 20 | Trailer-towing electronics interface |
| F12 | 20 | Hi-Fi amplifier power feed |
| F15 | 20 | Motorised panoramic glass roof sunblind. Factory table includes SW and non-hybrid RXH; occupancy depends on fitted roof and drivetrain |
| F16 | 5 | Driver-side electric-window switch panel |
Under-bonnet fuse box F20-F28
The 2012 Peugeot 508 RXH handbook documents F20 15 A for washer pumps, F21 20 A for headlamp washing, F22 15 A for the horn and F23/F24 15 A for the right/left high beams. Two further 5 A controls, F27 for the left headlamp mask and F28 for the right, were missing from the original Polish RXH table and have been restored here from the manufacturer. A 2016 English electronic handbook has an apparent F23 13 A transcription anomaly; the 2012 RXH factory publication explicitly gives 15 A. Check the original vehicle documentation and physical fuse if in doubt.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |

| F20 | 15 | Front and rear window-washer pump |
| F21 | 20 | Headlamp washer pump, if equipped |

| F24 | 15 | Left main-beam headlamp |
| F27 | 5 | Left headlamp mask/shutter control – listed in the 2012 Peugeot 508 RXH handbook; omitted from the older Polish summary |

Common electrical failures in Peugeot 508 RXH
Front cigarette lighter dead: Check left dashboard F13 10 A, and remove any metal object from the socket. Front accessory outlet dead: Check F14 10 A, not the lighter fuse. Rear passenger 12 V socket: Glovebox-box F3 15 A. Boot 12 V outlet: Glovebox-box F4 15 A. Inspect each outlet’s contacts if the correct fuse remains intact.
Rear wiper stopped: Left dashboard F30 20 A and the estate tailgate wiring loom. Front or rear electric windows: Behind-glovebox F6 30 A for front motors and F5 30 A for rear motors. No horn: Engine F22 15 A, followed by the horn and wiring. Only one high beam fails: Engine F23 or F24 15 A, then bulb or lamp controller.
Panoramic shade will not move: Behind-glovebox F15 20 A only where the fitted RXH has that circuit. A short in the blind drive or jammed guide cannot be corrected by a larger fuse. HYbrid4 READY unavailable: Check the condition of the 12 V battery and arrange a fault-code scan. Do not open or bypass the hybrid traction battery, disconnect high-voltage wiring or work on hybrid safety links.

The diesel-electric Peugeot 508 HYbrid4 (2012-2016) also uses distinct 12 V dashboard fuse carriers, but has separate high-voltage drive components. The standard Peugeot 508 I (2011-2018) covers the saloon and SW equipment variations. For a different raised hybrid vehicle see the Peugeot 3008 HYbrid4, whose 12 V hybrid controller positions are not the RXH assignments.
