The Ford C-MAX Mk1 (2003-2010), European version uses an engine-compartment fuse box and a passenger-compartment fuse box. The tables below retain the complete source numbering, including engine-specific alternatives such as the two F33 assignments and the two F119 ratings.
The C-MAX Mk1 shares parts of Ford’s C1-era electrical architecture with the Ford Focus Mk2 and later Ford Kuga Mk1, but the fuse assignments are not interchangeable between models.

FAQ – Ford C-MAX Mk1 fuses
Which fuses protect the heated windshield?
Engine-compartment fuse 14 – 40 A protects the right-hand side and fuse 16 – 40 A the left-hand side.
Where is the OBD-related fuse?
Passenger-compartment fuse 107 – 10 A supplies the instrument cluster battery feed and OBD diagnostics.
Where is the cigarette-lighter fuse?
Passenger-compartment fuse 109 – 20 A supplies the cigarette lighter and rear auxiliary power socket.
Why is fuse 33 listed twice?
The same engine-box position is used differently by powertrain: 10 A for oxygen sensors on gasoline engines and 10 A for the intercooler bypass valve on diesel engines.
Why is fuse 119 listed twice?
The luggage-compartment power outlet uses 15 A in the standard configuration and 25 A when the trailer-tow module is installed.
