GENERAL PRECAUTION
1. While using the battery during inspection, do not bring the positive (+) and negative (-) tester probes too close to each other as a short circuit may occur.
PRECAUTIONS WHEN USING INTELLIGENT TESTER
1. When using the intelligent tester with the power switch off to troubleshoot:
  
  Connect the intelligent tester to the vehicle, and turn a courtesy light switch on and off at 1.5-second intervals until communication between the intelligent tester and vehicle begins.
2. After all DTCs are cleared, check if the trouble occurs again 6 seconds after the power switch is turned on (IG).
DO NOT HANDLE REFRIGERANT IN ENCLOSED AREA OR NEAR OPEN FLAME

*1 Charging Cylinder
ALWAYS WEAR EYE PROTECTION
BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN YOUR EYES OR ON YOUR SKIN
If liquid refrigerant gets in your eyes or on your skin:
1. Wash the area with lots of cold water.
  
  CAUTION:
  
  Do not rub your eyes or skin.
2. Apply clean petroleum jelly to the skin.
3. Go immediately to a hospital or see a physician for professional treatment.
NEVER HEAT CONTAINER OR EXPOSE THE CONTAINER TO AN OPEN FLAME
BE CAREFUL NOT TO DROP CONTAINER OR APPLY PHYSICAL SHOCKS TO IT
DO NOT OPERATE COMPRESSOR WITHOUT ENOUGH REFRIGERANT IN AIR CONDITIONING SYSTEM

If there is not enough refrigerant in the A/C system, oil lubrication will be insufficient and the compressor may be damaged.

Necessary care should be taken to avoid this.
DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING
1. Open and close only the low pressure valve.
  
  If the high pressure valve is opened, refrigerant will flow in the reverse direction causing the charging cylinder to rupture.
BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH REFRIGERANT

If refrigerant is overcharged, it will cause problems such as insufficient cooling, poor fuel economy, engine overheating, etc.
DO NOT OPERATE COMPRESSOR WITHOUT REFRIGERANT

CAUTION:

Doing so may damage inside the compressor because the compressor parts always move regardless of whether the A/C system is turned on or off.
PRECAUTIONS TO BE OBSERVED WHILE SERVICING

CAUTION:

Always use electric insulating gloves and remove the service plug grip before beginning inspection, as inspection of the A/C system requires disconnecting high voltage connectors.
Note
- Only use ND-OIL11 for the electric inverter compressor of the air conditioning system. Using other compressor oils may be dangerous, as they may conduct electricity.
- Electrical insulation performance may decrease significantly if even a small amount of oil other than ND-OIL11 is used (or enters) in the refrigeration cycle, causing a DTC to be output.
- If other oil is accidentally used and a DTC is output, collect the compressor oil in the compressor and replace it with ND-OIL11 to increase the ND-OIL11 ratio amount.
- Replace the main components (evaporator, condenser, and compressor) if a large amount of oil other than ND-OIL11 enters the system. Failing to do so may cause electrical insulation performance to remain low, causing a DTC to be output.
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
1. This vehicle is equipped with a Supplemental Restraint System (SRS) such as the driver, front passenger, side and curtain shield airbags. Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the precautionary notices Click here.
