Depending on the model, your Mercedes-Benz Vito has a spare wheel under the vehicle floor. This is how you release it. Open the tailgate. Remove the cover and insert the add-on tool into the opening. Put the tyre wrench onto the add-on tool and rotate clockwise until you feel resistance or the slipping clutch spins. The spare wheel is now lowered. By using the handle on the carrier, you can pull out the spare wheel. To remove the carrier, lift it up and remove the gripper from the spare wheel. As long as the spare wheel is in use, you can transport the carrier in the back of your vehicle.
