Seat Arona 2022-2023 Fuses and Fuse Box

In the Seat Arona between the years 2022 and 2023, the fuse box and the complexities of fuses come together as unsung but important parts of the vehicle’s electrical system. The electrical connections in a car are protected by fuses, which are small and don’t look like much. When there is too much electricity or a problem, these simple parts work hard to break the connection and stop any damage or danger. These shields are kept in the fuse box, which is a quiet but important spot. The fuse box is also a place where fuses can be found and fixed. The fuse box is in a good place in the car to help with a wide range of electrical problems, from the lights to the music system to the air conditioning and more. Blown fuses, which can usually be seen as a broken or melted strip of metal, are a sign that something might be wrong in a certain circuit. To fix the problem without putting safety at risk, you must change the fuses with ones that have the same rating. The fuse box and the fuses inside it are important because they protect both the car’s parts and the people inside it. As technology and systems change, it becomes more important to understand and take care of these electrical sentinels. This is part of being a responsible car owner. The Seat Arona’s fuses and fuse box are a mix of simplicity and sophistication. They strike a good balance between modernity and durability, showing that the brand is committed to a smooth driving experience.

Fuses and bulbs Fuses

Introduction
In general, a fuse can be assigned to various electrical components. Likewise, an electrical component can be protected by several fuses. Only replace fuses when the cause of the problem has been solved. If a newly inserted fuse blows after a short time, you must have the electrical system checked by a specialized workshop as soon as possible.

WARNING
The high voltages in the electrical system can give serious electrical shocks, causing burns and even death!

• Never touch the electrical wiring of the ignition system.
• Take care not to cause short circuits in the electrical system.

WARNING

• Using unsuitable fuses, repairing fuses, or bridging a current circuit without fuses can cause a fire and serious injury.
• Never use a fuse with a higher value. Only replace fuses with a fuse of the same am amperage (same color and markings) and size.
• Never replace a fuse with a metal strip, staple or similar.

CAUTION

• To prevent damage to the vehicle’s electric system, before replacing a fuse always turn off the ignition, the lights, and all electrical elements and remove the key from the ignition.
• Protect the fuse boxes when open to prevent the entry of dust or humidity as they can damage the electrical system.

Note

• One component may have more than one fuse.
• Several components may run on a single fuse.
• In the vehicle, there are more fuses than those indicated in this chapter.

Note

• In the vehicle, there are more fuses than those indicated in this chapter. These should only be changed by a specialised workshop.
• Positions not containing a fuse do not appear in the following tables.
• Some of the equipment listed in the tables below pertain only to certain versions of the model or are optional extras.
• Please note that the above lists, while correct at the time of printing, are subject to change.

Changing bulbs
Introduction Changing bulbs requires a certain degree of practical skill. If you are unsure, SEAT recommends that you consult a technical service or request assistance from a specialist. In general a specialist is needed if, in addition to the bulbs, other vehicle components require removal. Always use identical bulbs with the same designation. The name can be found on the base of the bulb holder.
Depending on how equipped the vehicle is, there are different sets of headlights and tail lights:

• ECOLED (full-LED) main headlights
• High (full-LED) main headlights
• Rear bulb light
• LED rear light

Full-LED headlight system
Full-LED headlights handle all light functions (daylight, side light, turn signal, dipped beam and route light) with light emitting diodes (LEDs) as a light source. Full-LED headlights are designed to last the lifetime of the car and light bulbs cannot be replaced. In case of headlight failure, go to an authorised workshop to have it replaced.
Bulbs (12 V)
Depending on the level of equipment fitted in the vehicle, LEDs may be used for part or all of the interior and/or exterior lighting. LEDs have an estimated life that exceeds that of the vehicle. If an LED light fails, go to an authorised workshop for its replacement.

WARNING

• Bulbs are highly sensitive to pressure. The glass can break when you touch the bulb, causing injury.
• When changing the bulbs, take care not to injure yourself on parts with sharp edges.

CAUTION

• Remove the ignition key before working on the electric system. Otherwise, a short circuit could occur.
• Switch off the lights and the parking light before changing a bulb.
• Take good care to avoid damaging any components.

For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the proper manner.
Note

• Depending on weather conditions (cold or wet), the front lights, the fog lights, the tail lights and the turn signals may be temporarily misted. This has no influence on the useful life of the lighting system. By switching on the lights, the area through which the beam of light is projected will quickly be demisted. However, the edges may continue to be misted.
• Please check at regular intervals that all lighting (especially the exterior lighting) on your vehicle is functioning properly. This is not only in the interest of your own safety, but also that of all other road users.
• Before changing a bulb, make sure you have the correct new bulb.
• Do not touch the glass part of the bulb with your bare hands, use a cloth or paper towel instead, since the fingerprints left on the glass will vaporise as a result of the heat generated by the bulb, they will be deposited on the reflector and will impair its surface.
• Depending on the level of equipment fitted in the vehicle, LEDs may be used for part or all of the interior and/or exterior lighting. LEDs have an estimated life that exceeds than that of the car. If an LED light fails, go to an authorised workshop for its replacement.
