What type refridgerant is used on a 2003 hundai elantra?

The 2003 Hyundai Elantra uses R-134a refrigerant for its air conditioning system. This type of refrigerant is commonly used in vehicles manufactured before the widespread adoption of R-1234yf, which is more environmentally friendly but was introduced later. When servicing the air conditioning system, it's important to ensure that the correct refrigerant type is used to avoid potential damage.
