1. Shake the product before use. Fit the extension tube to the actuator knob.

2. With the vehicle and air conditioning system turned off, completely insert the extender into the air outlet diffuser and apply the product for approximately 8 seconds. Repeat the operation on all air outlets, shaking the tube before each application.

3. Be careful when removing the extension tube from the air outlets, to avoid splashing of the product on the panel or on some fragile surface, due to the risk of stains. If this happens, wipe immediately with a dry cloth.

4. For the complete action of the product, let it act for 10 minutes, without the presence of people in the vehicle, with the doors and windows closed. Then turn on the air conditioner in the cold, medium power and internal recirculation mode, and let the product act for 3 minutes. Finally, open the doors and ventilate the car before using it for at least 2 minutes. It is recommended to clean the cabinet of the filter and replace it, putting the new filter after applying the product, for a perfect cleaning of the ventilation system.

If it is easily accessible, it is also recommended to apply directly to the external air inlet, usually located next to the windshield (to make sure, refer to the vehicle manual). In this case, the application must be done with the air conditioning turned on in the cold and with the recirculation mode disabled. Turn off the air conditioner right after application.
