To check the fluid level, leave the engine idling.
Place the wheels in a straight position.
The liquid should be between the "max" and "min" marks.
The marks on the side are not visible on all models. In this case, you need to use the dipstick located under the tank cap.
Unscrew the lid (be careful, spring), wipe the dipstick with a clean cloth, place the cap on the filler hole (do not screw). Remove the cap again and check the oil level on the dipstick. It should be between the marks.
If necessary, add liquid up to the "max" mark.
In any case, the loss of working fluid indicates a leak in the system. In this case, it is important to first find the leak, and only then add fluid.
