2. The blower speed dial is turned completely counterclockwise to the OFF position.
3. The A/C switch is manually turned OFF.
In other words, the compressor ON request cannot be turned off in D/F or DEF modes.
REFRIGERANT PRESSURE PROTECTION
The refrigerant system is protected against excessively high- or low-pressures by the refrigerant pressure sen-
sor, located on the liquid tank on the condenser. The refr igerant pressure sensor detects the pressure inside
the refrigerant line and sends a voltage signal to the EC M. If the system pressure rises above or falls below
the following values, the ECM requests the IPDM E/ R to de-energize the A/C relay and disengage the com-
pressor.
• 3.12 MPa (31.82 kg/cm
2, 452.4 psi) or more (When the engine speed is less than 1,500 rpm)
• 2.74 MPa (27.95 kg/cm
2, 397.3 psi) or more (When the engine speed is 1,500 rpm or more)
• 0.14 MPa (1.43 kg/cm
2, 20.3 psi) or less
PRESSURE RELIEF VALVE
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
When the pressure of refrigerant in the system incr eases to an abnormal level [more than 2,990 kPa (30.5 kg/
cm
2, 433.6 psi)], the release port on the pressure relief valve automatically opens and releases refrigerant into
the atmosphere.
COMPRESSOR OIL CIRCULATION CONTROL
When the engine starts while the engine coolant temperature is 56 °C (133 °F) or less, ECM activates the com-
pressor for approximately 6 seconds and circulates the compressor lubricant once.
OPERATING RATE CONTROL
When the set temperature is other than fully cold or the air outlet is “VENT”, “B/L” or “FOOT”, the front air con-
trol controls the compressor activation depending on ambient temperature.
Door ControlINFOID:0000000009463200
DOOR MOTOR CONTROL
• A Local Control Unit (LCU) is built into each door motor and detects the door position by using a Position
Balanced Resistor (PBR).
• Each door motor LCU has a unique address. The front air control communicates with the door motor LCUs by using each door’s unique communication address. The front air control sends requested door position
commands to each door motor LCU via a Local Interconnect Network (LIN) communication line. Each door
motor’s LCU receives the command and sends back a door position feedback signal.
• Each LCU controls each door to the appropriate posit ion depending on the control signal from the front air
control. When the door movement is complete, the LCU transmits a signal to the front air control indicating
that the door movement is complete.

OIL LEVEL
• Before starting the engine, check the oil level. If t
he engine is already started, stop it and allow 10 minutes
before checking.
• Check that the oil level is within the range (A) on the oil level
gauge.
• If it is out of range, add oil as necessary.
ENGINE OIL APPEARANCE
• Check engine oil for white milky appearance or excessive contamination.
• If engine oil becomes milky, it is highly probable t hat it is contaminated with engine coolant. Repair or
replace damaged parts.
OIL LEAKAGE
Check for oil leakage around the following areas:
•Oil pan
• Oil pan drain plug
• Oil pressure switch
• Oil filter
• Oil cooler
• Valve timing control cover and valve timing control solenoid valve
• Front cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seal (front and rear)
OIL PRESSURE CHECK
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• Put the CVT shift selector in the Park "P" position.
1. Check engine oil level. Refer to OIL LEVEL.
2. Remove fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded View"
.
3. Disconnect oil pressure switch harness connector at oil pressure switch. Remove oil pressure switch and install Tools.
CAUTION:
Do not drop or shock oil pressure switch.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load, using Tool. NOTE:

WARNING:
• Be careful not to burn yourself, as the engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause skin cancer: try to avoid direct skin
contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as
possible.
1. Position the vehicle so it is level on the hoist.
2. Warm up the engine and check for oil leaks from the engine.
