The glass water filling port of the BMW 120i is on the left side of the engine compartment. The blue bottle cap is marked with a washing symbol. The glass water capacity of the BMW 120i is 4 liters. There is no fixed filling cycle, and it is generally added according to the usage situation. That's it, but don't wait until the water is completely dry before adding, because the dry wipe of the wiper not only has no cleaning effect, but may also cause scratches to the glass.
BMW 120i glass water addition process is as follows:
1. Turn on the wiper switch to make the glass water spray out;
2. Wait for a while, when the wiper nozzle stops spraying water, add a small amount of new glass water to the glass water filling port;
3. Turn on the working switch of the wiper again to clean up the old glass solution;
4. Wait for the water spray port to stop spraying water again, add 4 liters of glass water and replace the cover, and the filling is completed.
In different seasons, you should choose different glass water. For example, there are many dust and insects in summer. You can choose glass water with insecticide. This type of glass water can better clean the insect residue on the windshield, and the temperature in winter is lower. , In some northern regions, the outdoor temperature is even lower than freezing point, so it is necessary to choose antifreeze glass water.
