SERVICING CLIMATE CONTROL The climate control system in your INFINITI 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 INFINITI air conditioner. Using improper refrigerants or lubricants will cause severe damage to your climate control system. See "Capacities and recommended fuel/lubricants" in the "9. Technical and consumer information" for climate control system refrigerant and lubricant recommendations. Your INFINITI dealer will be able to service your environmentally friendly climate control system. OPERATING TIPS When the engine coolant temperature and outside air temperature are low, the air flow from the foot outlets may not operate for a maximum of 150 seconds. This is not a malfunction. After the coolant temperature warms up, air will flow normally from the foot outlets. IN-CABIN MICROFILTER The climate control 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 INFINITI Service and Maintenance Guide. To replace the filter, contact an INFINITI dealer. 4-28 Monitor, climate, audio, phone and voice recognition systems
