In this tutorial, you will learn how to change the gear oil in a Smart Roadster, a very simple and quick operation to be performed every 62,000 miles. First, wait for the engine to cool down, then lift the left rear side of the vehicle.

Identify the two indicated bolts and, using a Torx T50 spanner, remove both. Once all the oil has drained from the gearbox, tighten the lower bolt and add the necessary amount of oil through the upper hole.

For this last step, you can use a pump or a flexible tube.
