AIR BAG MODULES AND CLOCK SPRING
Caution
1. Disconnect the negative ( - ) battery terminal
and wait for 60 seconds or more before
starting work. Also, the disconnected
battery terminal should be insulated with
tape. (Refer to P.52B-3.)
2. Never attempt to disassemble or repair the
air bag modules and clock spring.
If faulty, just replace with new one(s).
3. Do not drop the air bag modules or clock
spring or allow contact with water, grease
or oil.
Replace if a dent, crack, deformation or rust
are present.
4. Store the air bag modules on a flat surface
with the deployment surface facing up.
Do not place anything on top of them.5. Do not store the air bag modules in a place
more than 93_C.
6. When the driver’s and front passenger’s air
bags have been deployed, replace the
driver’s and passenger’s air bag modules
with new ones.
7. Put on gloves and safety glasses when
handling deployed air bags.
8. When discarding the undeployed air bag
module(s), be sure to deploy the air bag(s)
in advance as specified in the service
procedure. (Refer to to P.52B-64.)

SRS -Seat Belt with Pre-tensioner52B-61
SEAT BELT WITH PRE-TENSIONER
Caution:
1. Wait for at least 60 seconds after
disconnecting the negative ( - ) terminal of
the battery before starting any operation.The
removed negative ( - ) terminal must be
protected by wrapping the tape. (Refer to
P.52B-3.)
2. Never disassemble or repair the seat belt
with pre-tensioner. Replace the part with a
new one when it malfunctions.
3. Take an extra care to deal with the seat belt
with pre-tensioner by avoiding dropping or
wetting it with water or oil. If any dent, crack,
or deformation is found, be sure to replace
the seat belt with pre-tensioner with a new
part.4. Do not place a heavy object on top of the
seat belt pre-tensioner.
5. Never keep the seat belt with pre-tensioner
in a place where the temperature can exceed
over 90_C.
6. Replace the seat belt with pre-tensioner with
a new one after operating the seat belt
pre-tensioner.
7. Wear gloves or protective glasses when
handling the seat belt with pre-tensioner
after operation.
8. If the seat belt with pre-tensioner before
operation needs to be discarded, be sure
to do so after operating the seat belt
pre-tensioner. (Refer to P.52B-64.)

Disposal Procedures52B-75
DEPLOYED AIR BAG MODULE OR OPERATED
SEAT BELT PRE-TENSIONER DISPOSAL
PROCEDURES
Discard the deployed air bag module or the operated seat
belt with pre-tensioner paying attention to the following items.
1. The deployment makes the inflator of the air bag or the
operation of the seat belt pre-tensioner very hot. Wait
for more than 30 minutes for cooling before handling
the inflator.
2. Do not apply any water or oil onto the deployed air bag
module or the operated seat belt pre-tensioner.
3. Wear gloves and protective glasses before handing the
deployed air bag module or the operated seat belt
pre-tensioner since materials on those parts may cause
irritation to eyes or skin.
Caution
If after following these precautions, any material does
get into the eyes or on the skin, immediately rinse the
affected area with a large amount of clean water.
If any irritation develops, seek medical attention.
4. Discard the air bag module and the seat belt with
pre-tensioner after placing them into a strong vinyl bag
for sealing.
5. Be sure to always wash your hands after completing this
operation.

8. Start the engine.
9. Operate the air conditioner and set at the lowest
temperature (MAX. COOL).
10. Fix the engine speed at 1,500 r/min.
11. Tighten the handle of the adaptor valve (valve open),
and replenish refrigerant while checking the quantity
through the sight glass.
Caution
If the service can is inverted, liquid refrigerant may
be draw into the compressor damaging it by liquid
compression. Keep the service can upright to ensure
that refrigerant is changed in gas state.
12. After replenishing is completed, turn the handle of the
adaptor valve all the way back (valve close), and remove
the quick joint.
NOTE
When there is remainder of refrigerant in the service can,
keep it for next use with the charge value and the valve
of the adaptor valve being closed.
DISCHARGING SYSTEM
Use the refrigerant recovery unit to discharge refrigerant gas
from the system.
NOTE : Refer to the Refrigerant Recovery and Recycling
Unit Instruction Manual for operation of the unit.
REFILLING OF OIL IN THE A/C SYSTEM
Too little oil will provide inadequate compressor lubrication
and cause a compressor failure. Too much oil will increase
discharge air temperature.
When a compressor is installed at the factory, it contains
130 cm
3of refrigerant oil. While the A/C system is in operation,
the oil is carried through the entire system by the refrigerant.
Some of this oil will be trapped and retained in various parts
of the system.
When the following system components are changed, it is
necessary to add oil to the system to replace the oil being
removed with the component.

REFRIGERANT LEAK REPAIR
LOST CHARGE
If the system has lost all charge due to a leak:
1. Evacuate the system. (See procedure.)
2. Charge the system with approximately one
pound of refrigerant.
3. Check for leaks.
4. Discharge the system.
5. Repair leaks.
6. Replace receiver drier.
Caution
Replacement filter-drier units must be
sealed while in storage. The drier used in
these units will saturate water quickly upon
exposure to the atmosphere. When
installing a drier, have all tools and supplies
ready for quick reassembly to avoid keeping
the system open any longer than necessary.
7. Evacuate and charge system.
LOW CHARGE
If the system has not lost all of its refrigerant charge;
locate and repair all leaks. If it is necessary to
increase the system pressure to find the leak
(because of an especially low charge) add
refrigerant. If it is possible to repair the leak without
discharging the refrigerant system, use the
procedure for correcting low refrigerant level.HANDLING TUBING AND FITTINGS
Kinks in the refrigerant tubing or sharp bends in
the refrigerant hose lines will greatly reduce the
capacity of the entire system. High pressures are
produced in the system when it is operating.
Extreme care must be exercised to make sure that
all connections are pressure tight. Dirt and moisture
can enter the system when it is opened for repair
or replacement of lines or components. The
following precautions must be observed. The
system must be completely discharged before
opening any fitting of connection in the refrigeration
system. Open fittings with caution even after the
system has been discharged. If any pressure is
noticed as a fitting is loosened, allow trapped
pressure to bleed off very slowly.
Never attempt to rebend formed lines to fit. Use
the correct line for the installation you are servicing.
A good rule for the flexible hose lines is keep the
radius of all bends at least 10 times the diameter
of the hose.
Sharper bends will reduce the flow of refrigerant.
The flexible hose lines should be routed so that
they are at least 80 mm from the exhaust manifold.
It is good practice to inspect all flexible hose lines
at least once a year to make sure they are in good
condition and properly routed.
Unified plumbing connections with O-rings, these
O-rings are not reusable.
COMPRESSOR NOISE
You must first know the conditions when the noise
occurs. These conditions are: weather, vehicle
speed, in gear or neutral, engine temperature or
any other special conditions.
Noises that develop during A/C operation can often
be misleading. For example: what sounds like a
failed front bearing or connecting rod, may be
caused by loose bolts, nuts, mounting brackets,
or a loose clutch assembly. Verify accessory drive
belt tension (power steering or alternator).
Improper accessory drive belt tension can cause
a misleading noise when the compressor is
engaged and little or no noise when the compressor
is disengaged.
Drive belts are speed-sensitive. That is, at different
engine speeds, and depending upon belt tension,
belts can develop unusual noises that are often
mistaken for mechanical problems within the
compressor.ADJUSTMENT
1. Select a quiet area for testing. Duplicate
conditions as much as possible. Switch
compressor on and off several times to clearly
identify compressor noise. To duplicate high
ambient conditions (high head pressure),
restrict air flow through condenser. Install
manifold gauge set to make sure discharge
pressure doesn’t exceed 2,070 kPa.
2. Tighten all compressor mounting bolts, clutch
mounting bolt, and compressor drive belt.
Check to assure clutch coil is tight (no rotation
or wobble).
3. Check refrigerant hoses for rubbing or
interference that can cause unusual noises.
4. Check refrigerant charge. (See “Charging
System”.)
5. Recheck compressor noise as in Step 1.
6. If noise still exists, loosen compressor mounting
bolts and retorque. Repeat Step 1.
7. If noise continues, replace compressor and
repeat Step 1.
