Get Do it yourself -> Replacing fuses Guide for Volkswagen Jetta 4 Door Seventh Generation (2019-2025)

Replacing fuses

Introduction

Due to the constant development of the vehicle, equipment-dependent fuse allocations, and the combined protection of

multiple electrical equipment items using one fuse, a complete overview of the fuse layout is not available at the time of print.

Detailed information about fuse allocations can be obtained from suitably qualiﬁed professionals. Volkswagen recommends

contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Generally, multiple electrical equipment items can be protected together through by fuse. On the other hand, some equipment

items may use multiple fuses.

Only replace fuses if the cause for the malfunction has been ﬁxed.

1. If a new fuse blows again after a short time, have the electrical system checked by suitably qualiﬁed professionals.

Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

WARNING

The high voltage in the electrical system may cause electric shocks and severe burns. Contact with electric wires in the

ignition system may result in serious or fatal injuries.

Never touch the electrical wires in the ignition system.

WARNING

Using unsuitable fuses, repairing fuses or bridging a circuit without fuses can lead to serious damage or a ﬁre in the

vehicle. This could result in serious or fatal injuries.

Replace fuses only with fuses of same rating and size. Make sure that the color and label are identical to the faulty

fuse.

Never repair fuses.

Never use metal strips, paper clips or similar objects as substitutes for fuses.

NOTICE

Changing a fuse when the ignition is switched on, the engine is running, the light is switched on, or other electrical

equipment is switched on could cause damage to the electrical system.

Switch off the engine and turn off the light and other electrical equipment.

Make sure that the engine cannot be started while a fuse is being replaced.

NOTICE

If a fuse is replaced by another fuse with a higher amp rating, this could also damage the vehicle's electrical system in

another location.

Never replace a fuse with a fuse that has a higher current rating.

NOTICE

340

Dirt and moisture in the fuse boxes can damage the electrical system.

Protect open fuse boxes from dirt and moisture.

Avoid short circuits in the electrical system.

Check that the fuse box covers are tightly sealed again and are not damaged.

There are other fuses in the vehicle. These should only be replaced by an authorized Volkswagen dealer or authorized

Volkswagen Service Facility qualified in this respect. Volkswagen recommends contacting an authorized Volkswagen

dealer or authorized Volkswagen Service Facility.

NOTICE

If a fuse is replaced by a fuse with a higher current rating, this could damage the electrical system in another location.

Never replace a fuse with a fuse that has a higher current rating.

Jump-starting

Introduction

For technical reasons the vehicle must not be tow-started ⇒

. If the engine cannot start because the 12 V vehicle battery i

dead, the 12 V vehicle battery on another vehicle can be used to start your vehicle.

For vehicles with a 12 V vehicle battery in the vehicle interior or luggage compartment, the jumper cables may only be

connected to the jump-start points in the hood space.

WARNING

Using jumper cables incorrectly and performing a jump-start incorrectly could cause the 12 V vehicle battery to explode.

Serious injuries may result.
