Fuses
Fuse Replacement
WARNING: Fuses protect the vehicle’s electrical systems. The failure of any fuse will render the system it protects inoperative.
WARNING: Always use replacement fuses of the same rating and type. Incorrect fuse ratings can overload a system and cause a fire or malfunction.
WARNING: 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. |
| Fuse Box | Location |
| Secondary fuse box | Below the dashboard on the passenger’s side. |
| Battery fuse box | On top of the battery. |
