TO TURN THE SYSTEM ON/OFF Push the "OFF" or "ON·OFF" button when the heater and air conditioner is off. The system will turn on with the settings that were used immediately before the system was turned off. The filter should be replaced if air flow is extremely decreased or when windows fog up easily when operating heater or air conditioning system. SERVICING AIR CONDITIONER The air conditioning system in your NISSAN is charged with a refrigerant designed with the environment in mind. This refrigerant will not harm the earth's ozone layer. However, special charging equipment and lubricant are required when servicing your NISSAN air conditioner. Using improper refrigerants or lubricants will cause severe damage to your air conditioning system. (See "CAPACITIES AND RECOMMENDED FUEL/LUBRICANTS" in the "9. Technical and consumer information" section for air conditioning system refrigerant and lubricant recommendations.) Your NISSAN dealer will be able to service your environmentally friendly air conditioning system. SAA1989 OPERATING TIPS A The sunload sensor * on the instrument panel helps maintain a constant temperature. Do not put anything on or around this sensor. IN-CABIN MICROFILTER The air conditioning system is equipped with an in-cabin microfilter which collects dirt, pollen, dust, etc. To make sure the air conditioner heats, defogs, and ventilates efficiently, replace the filter in accordance with the maintenance schedule in the NISSAN Service and Maintenance Guide. To replace the filter, contact a NISSAN dealer. WARNING The system contains refrigerant under high pressure. To avoid personal injury, any air conditioner service should be done only by an experienced technician with the proper equipment. 4-32 Center display, heater, air conditioner, audio, phone and voice recognition systems
