MAINTAINING YOUR VEHICLE 313 WARNING! • Use only refrigerants approved by this manufacturer for your air conditioning system. Some unapproved refrigerants are flammable and can explode, injuring you. Other unapproved refrigerants can cause the system to fail, requiring costly repairs. • Never add air conditioning refrigerant to correct a non-cooling problem unless pressure gauges are connected to the system by a certified technician. Lack of cooling could be due to a restriction and adding refrigerant may cause a dangerous pressure rise and you could be injured. Refrigerant Recovery And Recycling The air conditioning system of your vehicle contains R-134a, a refrigerant that does not deplete the ozone layer in the upper atmosphere. The manufacturer recommends that air conditioning service be done by facilities using refrigerant recycling and recovery equipment that meets SAE standard J1991. A/C Air Filter The filter access door is located under the instrument panel on the passenger side. To replace the filter slide the lock toward the rear of the vehicle (unlock position). Remove the access door and pull the filter downward. When installing a new filter, ensure its proper orientation. Align the black arrow on the bottom of the filter frame with the direction of airflow (away from the blower motor and towards the center of the car). Refer to the "Maintenance Schedules" section of this manual for the recommended air conditioning filter replacement intervals. 7
