Checking and Replacing Fuses in VW Tiguan III
Caution!
Using unsuitable fuses, repairing fuses, and bridging a power circuit without fuses can causes fires and serious 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.
- To avoid damage to the electrical system in the vehicle, switch the ignition, the lights and all electrical consumers off and remove the vehicle key from the ignition before changing a fuse.
