Nissan Sentra B18 (2020-2025) Owner's Manual: Servicing air conditioner
The air conditioning system in your Nissan Sentra is charged with an environmentally friendly refrigerant designed to minimize environmental impact while maintaining efficient cooling performance.
This refrigerant does not damage the earth’s ozone layer and complies with current environmental standards.
Servicing the Nissan Sentra air conditioning system requires specialized charging equipment and approved lubricants. The use of incorrect refrigerants or lubricants can cause serious damage to system components and reduce overall performance.
For this reason, it is strongly recommended that you have your Nissan Sentra air conditioning system serviced by an authorized NISSAN dealer or a qualified technician familiar with environmentally friendly refrigerant systems.
WARNING
The air conditioner system contains refrigerant under high pressure. To avoid personal injury, all air conditioning service and maintenance must be performed only by experienced technicians using proper equipment.
