Subaru Crosstrek Service Manual: Procedure
HVAC SYSTEM (HEATER, VENTILATOR AND A/C) > Refrigerant Pressure with Manifold Gauge Set
PROCEDURE
1. REFRIGERANT GAS PRESSURE INSPECTION
1. Prepare the vehicle.
NOTE:
Check that the ambient temperature is 25 — 40°C (77 — 104°F) and that the humidity is 30% — 80%.
• Place the vehicle in the shade and windless condition, and open the front hood.
• Open the front windows and close all doors.
2. Check the refrigerant pressure.
Preparation tool:
Manifold gauge set
(1) Connect the manifold gauge set, and start the engine.
(2) Set the vehicle to the following conditions.
Item | Condition |
Engine | Warmed up (Engine coolant temperature indicator light: OFF) |
Air vent grille | Shutter is fully open. |
A/C switch | ON |
Temperature adjustment dial | LO (MAX COOL) |
FRESH/RECIRC switch | RECIRC |
Air flow control dial or switch | VENT |
Fan dial | Auto A/C model: 5/7 level |
Manual A/C model: 3/4 level |
(3) In the condition of step (2), idle the engine for 30 minutes.
(4) Read the gauge values on both high pressure side and low pressure side for manifold gauge.
3. Measure the air vent grille outlet opening temperature, ambient temperature and humidity.
Preparation tool:
Thermometer and hygrometer
NOTE:
For outlet opening temperature, measure the average temperature of center grille assembly and side grille assembly.
4. Check that the high and low pressures and outlet opening temperature for ambient temperature and humidity is within the standard value described in the chart below.
5. Refer to “DIAGNOSIS WITH SYMPTOM” if the inspection result is not within the standard value. Refrigerant Pressure with Manifold Gauge Set > INSPECTION">

Fastening the seatbelt
WARNING
Never use a belt that is twisted or
reversed. In an accident, this can
increase the risk or severity of
injury.
Keep the lap belt as low as
possible on your hips. In a collision,
this spreads the force of the
lap belt over stronger hip bones
instead of across the weaker
