How do you check the gearbox oil on a mercedes a160?

To check the gearbox oil on a Mercedes A160, first ensure the vehicle is on a level surface and the engine is warm. Locate the transmission dipstick, usually found near the back of the engine bay, and remove it to wipe it clean. Reinsert the dipstick fully, then remove it again to check the oil level; it should be within the marked range. If necessary, add the appropriate Transmission Fluid through the dipstick tube or designated fill port, ensuring not to overfill.
