SERVICE INFORMATION

This service information is to serve as a warning against the use of an air conditioning refrigerant R-12 substitute known as "AlaskanKool R-176".

This product is promoted as being a CFC replacement refrigerant, and is claimed to have superior qualities as compared to R-12 refrigerant.

Initial findings of the Technical Committee of the Association of International Automobile Manufacturers indicate that the use of this R-176 refrigerant causes serious damage to air conditioning systems, including Mercedes-Benz. Therefore, its use in any form in the servicing of our air conditioning systems is strictly not authorized.

It is requested that you ensure that this refrigerant is not used in any manner in the repair and servicing of Mercedes-Benz vehicles in your service department.
