Air Conditioning System Standard for LX and EX models in the U.S., and LX and Si models in Canada Optional for other models Your car's air conditioning is a sealed system. Any major maintenance, such as recharging, should be done by a qualified mechanic. You can do a couple of things to make sure the air conditioning works efficiently. 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 289 .) The condenser and radiator f ins bend easily. Only use a low-pressure spray or sof t-bristle brush to clean them. 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. Whenever you have the air conditioning system serviced, make sure the service f acility uses a ref rigerant recycling system. This system captures the ref rigerant f or reuse. Releasing ref rigerant into the atmosphere can damage the environment. AIR CONDITIONING CONDENSER 228 Maintenance
