Part: Checks and maintenance

In today's video, you will see how to replace the horn on a first-generation Smart. First, ensure the vehicle is stationary to avoid touching hot or heated parts. Lift the vehicle (you can use a ramp, as you need to work on the front of the vehicle) and locate the horn in the middle of the car. Remove it and proceed to install a new piece of the same type, paying attention to the power connectors.
