Air Conditioning Optional for Canadian S model Your car's air conditioning is a sealed system. Any major maintenance, such as recharging, should be done by a qualified technician. There are a couple of things you can do to make sure the air conditioning works efficiently. AIR CONDITIONING CONDENSER Periodically check the engine's radiator and air conditioning condenser for leaves, insects, and dirt stuck to the front surface. These block the air flow and reduce cooling efficiency. Use a light spray from a hose or a soft brush to remove them. If the air conditioning does not get as cold as before, have your dealer check the system. Recharge the system with Refrigerant HFC-134a (R-134a). (See Specifications on page 215.) NOTICE The condenser and radiator fins bend easily. Only use a low-pressure spray or soft-bristle brush to clean them. NOTICE Whenever you have the air conditioning system serviced, make sure the service facility uses a refrigerant recycling system. This system captures the refrigerant for reuse. Releasing refrigerant into the atmosphere can damage the environment. Run the air conditioning at least once a week during the cold weather months. Run it for at least ten minutes while you are driving at a steady speed with the engine at normal operating temperature. This circulates the lubricating oil contained in the refrigerant. Maintenance
