Fuses: which fuse powers what
Every fuse and relay in the three fuse boxes, from the circuit diagrams, with the 2024 and 2025 wiring side by side (≠ marks a position that differs).
Where the boxes are (owner's manual): the front compartment box is located at the left rear of the motor compartment
(press the clips on both sides and lift the lid); the dashboard box becomes accessible after the driver side lower guard plate
assembly is removed
; the third box sits on the 12 V battery's positive terminal.
Which wiring does your car have? In the front compartment box, positions EF43, EF44 and EF45 are empty on the 2024 wiring and hold 15 A fuses on the 2025 wiring. In the box on the 12 V battery, the 2024 wiring has a 60 A fuse marked ITS; on the 2025 wiring that position is empty. The label inside a fuse-box lid lists every position. If a car matches neither pattern, its export wiring differs from both China editions: go by the lid label.
Never fit a bigger fuse: Never use a fuse higher than the amperage rating, or substitute any other item for the fuse, as this
may result in the vehicle damage, fire or personal injury.
High-voltage fuses are inside the sealed high-voltage units, not in these boxes.
