How do you check Renault modus auto gearbox fluid levels?

To check the gearbox fluid levels in a Renault Modus, first ensure the vehicle is on a level surface and the engine is warm. Locate the gearbox dipstick or filler plug, typically found near the transmission. Remove the dipstick, wipe it clean, reinsert it, and then remove it again to check the fluid level; it should be between the minimum and maximum marks. If low, add the appropriate type of gearbox fluid through the filler plug, ensuring not to overfill.
