cover it with the disc wheel with tire.
NOTICE:
Place the front seat outer belt as shown in the illustration.
(3) Move the SST to at least 10 m (33 ft) away from the
disc wheel.
NOTICE:
Take care not to damage the SST wire harness.
(d) Activate the seat belt pretensioner.
(1) Connect the SST red clip to the battery positive (+)
terminal and black clip to the battery negative (±)
terminal.
(2) Check that no one is within 10 m (33 ft) area around
the disc wheel.
(3) Press the SST activation switch and activate the
seat belt pretensioner.
HINT:
The seat belt pretensioner operates simultaneously as the LED
of the SST activation switch lights up.
(e) Dispose of the front seat outer belt (with seat belt preten-
sioner).
CAUTION:

The front seat outer belt is very hot when the seat belt
pretensioner is activated, so leave it alone for at least
30 minutes after activation.

Use gloves and safety glasses when handling a front
seat outer belt with activated seat belt pretensioner.

Always wash your hands with water after completing
the operation.

Do not apply water, etc. to a front seat outer belt with
activated seat belt pretensioner.
(1) Remove the disc wheel and SST.
(2) Place the front seat outer belt in a vinyl bag, tie the
end tightly and dispose of it in the same way as oth-
er general parts.

INSTALLATION
NOTICE:

Never use seat belt pretensioner from another ve-
hicle. When replacing parts, replace them with new
parts.

Make sure that the front seat outer belt is installed to
the specified torque.

If the front seat outer belt has been dropped, or there
are cracks, dents or other defects in the case or con-
nector, replace the front seat outer belt with a new
one.

When installing the front seat outer belt, take care that
the wiring does not interfere with other parts and is
not pinched between other parts.
1. Other front seat outer belts:
INSTALL RETRACTOR OF FRONT SEAT OUTER BELT
(a) Install the retractor of front seat outer belt with the 2 bolts.

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 physician or hospital for professional
treatment.
4. NEVER HEAT CONTAINER OR EXPOSE IT TO OPEN
FLAME
5. BE CAREFUL NOT TO DROP CONTAINER OR NOT TO
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 PRESSURE MANIFOLD VALVE WHILE
COMPRESSOR IS OPERATING
If the high pressure valve is opened, refrigerant flows in the re-
verse direction and could cause the charging cylinder to rup-
ture, so open and close only the low pressure valve.
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.

9. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The SEQUOIA is equipped with an SRS (Supplemental Re-
straint System) such as the driver, passenger, side, and curtain
shield airbags. 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 in
the RS section.

ifold gauge set. Read the manifold gauge pressure when the
conditions below are met.
