FUSES
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 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.
GENERAL INFORMATION
The fuses protect electrical systems against excessive current.
When a device does not work, you must check the fuse element inside the blade fuse for a break/melt.
Also, please be aware that when using power outlets for extended periods of time with the engine off may result in vehicle battery discharge.
Blade Fuses
- Fuse Element
- Blade Fuse with a good/functional fuse element
- Blade fuse with a bad/not functional fuse element (blown fuse)

CAUTION!
- When installing the power distribution centre cover, it is important to ensure the cover is properly positioned and fully latched. Failure to do so may allow water to get into the power distribution centre and possibly result in an electrical system failure.
- When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected.
FAQs
A fuse is a safety device that prevents electrical circuits from overloading. It has a wire that melts if the current exceeds a certain threshold, breaking the circuit.
Visually inspect the fuse for any broken wires or discolorations. Some fuse boxes include a fuse diagram to help you identify the purpose of each fuse.
Typically, all you need is a pair of needle-nose pliers or a fuse puller, which are usually included in the fuse box.
No, always replace a blown fuse with one with the same amperage rating. Using a higher amp fuse may result in electrical damage or even a fire.
Check your vehicle’s owner’s manual or the fuse box cover for a fuse chart that shows the amp rating of each fuse.
Many automakers offer owner’s manuals online. You can also visit the vehicle manufacturer’s website or contact customer service.
To remove a fuse, use a fuse puller or needle-nose pliers to grip the fuse and pull it straight out.
If a fuse continues to blow, it could indicate an underlying problem with the electrical system. Consult a professional mechanic for a thorough inspection.
It depends on the fuse’s function. Critical systems such as lights and brakes can jeopardize your safety, so replace blown fuses before driving.
To replace a fuse in the dark, use a flashlight or smartphone’s flashlight feature to illuminate the fuse box.
Disconnecting the battery is not always necessary, but it can add an extra layer of safety when working with the electrical system.
Seek professional assistance from a qualified mechanic or auto electrician to identify and resolve the underlying problem.
No, always use the correct fuse type and amp rating listed in the owner’s manual or fuse box.
Remember that these are general guidelines, and you should always refer to your vehicle’s documentation for accurate information. If you’re unsure or uncomfortable with electrical components, seek professional help.
