Fuses
Fuse replacement
WARNING: Fuses protect the vehicle’s electrical systems. The failure of any fuse will render the system it protects inoperative.
Use replacement fuses of the same rating and type. Incorrect fuse ratings can overload a system and cause a fire or malfunction. Blown fuses should be replaced and no attempt should be made to repair a blown fuse.
NOTE: Before removing a fuse, turn off all electrical equipment and switch off the ignition.
There are three fuse boxes fitted to your McLaren.
| Fuse Box | Location |
| Main fuse box | Behind a panel in the rear bulkhead, behind the left-hand seat. |
| Secondary fuse box | Below the dashboard on the passenger’s side. |
| Battery fuse box | On top of the battery, in the luggage compartment, beneath the luggage compartment cover. |
Main Fuse Box
Main fuse box access
- To access the main fuse box:
- If a manual seat is fitted, lift the tilt release lever and tilt the left-hand seat backrest forwards
- If an electric seat is fitted, pull the release strap (shown above) and tilt the left-hand seat backrest forwards
- Release the two lower clips securing the panel to the bulkhead and remove the panel.
- Refer to the fuse specification to determine which fuse protects the non-functioning electrical system, see Main fuse box fuse specification chart, page 6.20.
NOTE: A label identifying the fuses is attached to the inside of the access panel.
Remove the appropriate fuse and replace it with a fuse of the same value as the original. If in doubt, check the fuse specification chart. - Fit the access panel by inserting the two upper retaining clips in the bulkhead and securing with the two lower clips.
NOTE: If a replacement fuse does not solve the electrical problem, or it fails immediately, contact your McLaren retailer.
