*For the execution of the charging and discharging operation in the table above, refer to Recovery, Recycling, Evacuating and Charging.

Checking The Refrigerant System With Manifold Gauge
Since Refrigerant-134a (HFC-134a) is used in the air conditioning system in this vehicle, be sure to use manifold gauges, charging hoses and other air conditioning service tools for HFC-134a when checking the refrigerant system.

Conditions:
- Run the engine at Idling
- Air conditioning switch is "ON"
- Run the blower motor at "HIGH" position
- Temperature control lever set to "MAX COLD"
- Air source selector lever at "CIRC"
- Open the engine hood
- Close all the doors

Normal Pressure:
- At ambient temperature: approx. 25-30 °C (77-86 °F).
- At low-pressure side: approx. 147.1-294.2 kPa (21.3-42.7 psi).
- At high-pressure side: approx. 1372.9-1863.3 kPa (199.1-270.2 psi).





Refer to the table on the refrigerant pressure-temperature relationship.
