Toyota Yaris: Air Conditioning System / Precaution

Toyota Yaris XP210 (2020-2026) Reapir and Service Manual / Vehicle Interior / Heating / Air Conditioning / Air Conditioning System / Precaution

PRECAUTION

DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME

*a	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.

(a) Wash the area with lots of cold water.

CAUTION:

Do not rub your eyes or skin.

(b) Apply clean petroleum jelly to the skin.

NEVER HEAT CONTAINER OR EXPOSE 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 REFRIGERANT SYSTEM

If there is not enough refrigerant in the air conditioning 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

*a	Wrong
*b	Okay

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 the system is overcharged with refrigerant, it causes problems such as insufficient cooling, poor fuel economy, engine overheating, etc.

DO NOT OPERATE ENGINE AND COMPRESSOR WITH NO REFRIGERANT

CAUTION:

Doing so may damage the inside of the compressor because the compressor parts always move regardless of whether the air conditioning system is turned on or off.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

This vehicle is equipped with a Supplemental Restraint System (SRS). 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.
