PRECAUTION
1.
DO NOT HANDLE REFRIGERANT IN AN ENCLOSED
AREA OR NEAR AN OPEN FLAME
2.
ALWAYS WEAR EYE PROTECTION
3.
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 cool water.
CAUTION:
Do not rub your eyes or skin.
(b)
apply clean petroleum jelly to the skin.
(c)
go immediately to a hospital or see a physician for profes-
sional treatment.
4.
NEVER HEAT CONTAINER OR EXPOSE IT TO NAKED
FLAME
5.
BE CAREFUL NOT TO DROP CONTAINER OR APPLY
PHYSICAL SHOCKS TO IT
6.
DO NOT OPERATE COMPRESSOR WITHOUT
ENOUGH REFRIGERANT IN REFRIGERATION SYS-
TEM
If there is not enough refrigerant in the refrigerant system, oil lu-
brication will be insufficient and compressor burnout may occur.
Necessary care should be taken to avoid this.
7.
DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE
WHILE COMPRESSOR IS OPERATE
Open and close only the low pressure valve. If the high pressure
valves are opened, refrigerant flows in the reverse direction
causing the charging cylinder to rupture.
8.
BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH
REFRIGERANT
If refrigerant is overcharged, it causes problems such as insuffi-
cient cooling, poor fuel economy, engine overheating etc.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The SEQUOIA is equipped with an SRS (Supplemental Re-
straint System) such as the driver, passenger, side, curtain
shield airbag. Failure to carry out service operation in the cor-
rect 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 tn
the RS section.
