2020 Alfa Romeo Giulia Quadrifoglio Fuses and Fuse Box Instructions
It is very important to understand the fuses and fuse box in the 2020 Alfa Romeo Giulia Quadrifoglio because they protect electrical circuits and make the car work. This system carefully combines Italian design and engineering accuracy, making sure that the electrical parts of the car work smoothly and protecting against problems that could happen. The fuse box is placed in a smart way inside the car. It contains a network of fuses that cut power to certain circuits in case of an electrical fault or overload. This detailed guide delves into the Giulia Quadrifoglio’s fuses and fuse box, explaining how important they are for maintaining the vehicle’s performance and safety and giving owners the skills to successfully troubleshoot and fix electrical problems.
FUSES
General Information
The fuses protect electrical systems against excessive current. When a device does not work, you must check the electrical circuit inside of the fuse for a break/melt. Also, please be aware that using power outlets for extended periods of time with the engine off may result in vehicle battery discharge.

Fuse Extracting Pliers
To replace a fuse, use the pliers hooked to the fuse box. 
Grab the pliers from the upper tabs, press them, and extract the pliers pulling upwards. The pliers have two different ends, both of which are specifically designed to remove the different types of fuses present in the vehicle:
Fuse Extracting Pliers
- MINI fuse
- J-CASE fuse
After use, return the pliers to their proper position by following the below procedures:
- Grasp the pliers from the upper tabs and insert them into their housing.
- Push downward on the pliers into their housing until they click into place.
Warning
- When replacing a blown fuse, always use an appropriate replacement fuse with the same amp rating as the original fuse. Never replace a fuse with another fuse of a higher amp rating. Never replace a blown fuse with metal wires or any other material. Do not place a fuse inside a circuit breaker cavity or vice versa. Failure to use proper fuses may result in serious personal injury, fire, and/or property damage.
- Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/or disengaged.
- If the replaced fuse blows again, contact an authorized dealer.
- If a general protection fuse for safety systems (air bag system, braking system), power unit systems (engine system, transmission system), or steering system blows, contact an authorized dealer.
Fuse Location
The fuses, which can be replaced by the user, are grouped in two boxes below the passenger side footboard and inside the trunk.
Control Unit Under Passenger Side Footboard
To access the fuses, proceed as follows:
- Lift the upper end of the footboard on the passenger side, pulling to release the two buttons.
- Unscrewing the two hooks, remove the panel pulling downward.
The fuses are freely accessible on the control unit. After replacing the fuse, make sure that the panel and footboard are correctly locked.
Luggage Compartment Fuse Box
To access the fuses, proceed as follows:
- Lift the luggage compartment cover.
- Remove the control unit cover.
The fuses are freely accessible on the control unit. The number identifying the electrical component corresponding to each fuse is shown on the cover. After replacing a fuse, make sure that you have closed the cover correctly.
