Fuse Replacement
Used Fuses Characteristics When an electrical device is not functioning, check that the corresponding fuse is in proper working order (intact).
- A Fuse intact
- B Fuse blown
Replace the faulty fuse with a new one featuring the same rating, by using appropriate forceps added in the integrated power module and inside the cover of the rear power distribution centre. 
The color identifies the value of the fuses in amperes which is also reported on them. The vehicle is endowed with mini-and maxi-fuses. The table shows the match between color and amperage of mini and maxi fuses.
| Type | Colour / Ampere | ||||||
| Mini Fuse | Beige – 5 | Brown – 7,5 | Red – 10 | Blue – 15 | Yellow – 20 | White – 25 | Green – 30 |
| Maxi Fuse | Yellow – 20 | Green – 30 | Orange – 40 | Red – 50 | Blue – 60 | ||
CAUTION!
-
Never replace a blown fuse with anything other than a new and suitable fuse (same rating).
-
After replacing a fuse, if the fault recurs, contact the Service Network.
Position of Fuses The fuses are located in three parts of the vehicle, namely:
- Inside the integrated power module, on the right-hand side of the engine compartment;
