" Mercedes-Benz Genuine Air Conditioning
Cleaning for a Fresher Interior.

Dear Paul,

Your Mercedes-Benz has a highly efficient and reliable heating, ventilation and
air-conditioning system (HVAC). At times, however, certain unfavorable conditions (see "Did You Know?" below) can negatively affect your cooling system, decreasing the comfort and quality of your driving experience.

Good news! If the cool blast coming from the vents on a hot afternoon is not as refreshing as you would like it to be, Mercedes-Benz has a quick service procedure using a product specifically developed to thoroughly cleanse and revitalize the entire HVAC system.

Your Mercedes-Benz certified technician applies an odorless foam to effectively clean and disinfect every component, removing contaminants — with no trace of the product remaining in the system. HVAC cleaning is a fast and easy process that can usually be done while you wait or during regular vehicle maintenance.

Call (xxx) xxx-5690 for more information about HVAC cleaning and to schedule an appointment. We look forward to the next opportunity to provide the service experience you expect from Mercedes-Benz."
