SERVICING AIR CONDITIONER AMBIENT TEMPERATURE SWITCH (AMB) Push the ambient temperature switch. The outside ambient temperature will be displayed for approximately 5 seconds. The ambient temperature sensor is located in front of the radiator. The sensor may be affected by road or engine heat, wind direction and other driving conditions. The display may differ from the actual ambient temperature or the temperature displayed on various signs or billboards. The air conditioning system in your NISSAN vehicle 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 "10. Technical and consumer information" section for air conditioning system refrigerant and lubricant recommendations. HA1011 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. However, this is not a malfunction. After the coolant temperature warms up, the air flow from the foot outlets will operate normally. The sensor on the instrument panel helps maintain a constant temperature; do not put anything on or around this sensor. Your NISSAN dealer will be able to service your environmentally friendly air conditioning system. WARNING The air conditioner system contains refrigerant under high pressure. To avoid personal injury, any air conditioner service should be done only by an experienced technician with proper equipment. Heater, air conditioner and audio systems 4-11
