SRS -Seat Belt Pre-tensioner Disposal Procedures52B-14
SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURES
Before disposing of a vehicle which is equipped
with seat belts with pre-tensioner, or when disposing
of the seat belts with pre-tensioner themselves,the following procedures must be used to deploy
the pre-tensioners before disposal.
UNDEPLOYED SEAT BELT PRE-TENSIONER
DISPOSAL
Caution
1. If the vehicle is to be scrapped or otherwise disposed
of, operate the pre-tensioners inside the vehicle. If
the vehicle is still to be used and only the seat belt
pre-tensioner are to be disposed of, operate the
pre-tensioners outside the vehicle.
2. Since a large amount of smoke is produced when
the pre-tensioner is operated, avoid residential areas
whenever possible.
3. Since there is a loud noise when the pre-tensioners
are operated, avoid residential areas whenever
possible. If anyone is nearby, give warning of the
impending noise.
4. Suitable ear protection should be worn by personnel
performing these procedures or by people in the
immediate area.
DEPLOYMENT INSIDE THE VEHICLE
1. Move the vehicle to an isolated spot.
2. Disconnect the negative ( - ) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.
Caution
Wait at least 60 seconds after disconnecting the
battery cables before doing any further work.
(Refer to P.52B-4.)
3. Operate the pre-tensioner as specified in the service
procedures that follows.
(1) Remove the center pillar trim, lower.

SRS -Seat Belt Pre-tensioner Disposal ProceduresSRS -Seat Belt Pre-tensioner Disposal Procedures52B-16
Caution
1) Before operating the pre-tensioner, see that
no one is in and near the vehicle.
2) The operation of the pre-tensioner makes the
inflator very hot. Before handling the inflator,
wait more than 30 minutes for cooling.
3) If the pre-tensioner fails to operate when the
procedures above are followed, do not go near
the pre-tensioner. Contact your local
distributor.
(7) After operation of the pre-tensioner, discard as
specified in the procedure. (Refer to P.52B-18.)
DEPLOYMENT OUTSIDE THE VEHICLE
Caution
1) This should be carried out in a wide, flat area at least
6 m away from obstacles and other people.
2) Do not operate outside if wind is high. Even in a soft
wind, ignite to windward of the pre-tensioner.
1. Disconnect the negative ( - ) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.
Caution
Wait at least 60 seconds after disconnecting the
battery cables before doing any further work. (Refer
to P.52B-4.)
2. Operate pre-tensioner as specified in the service
procedures that follows.
(1) Remove the seat belt pre-tensioner from the vehicle.
(Refer to P.52B-12.)
Caution
The pre-tensioner should be stored on a flat
surface and placed so that the pre-tensioner
operation surfaces are facing upward. Do not
place anything on top of them.

HEATER, AIR CONDITIONER AND VENTILATION - On-vehicle Service55A-17
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.
