GENERAL PRECAUTIONS
The WARNING and CAUTION below describe some general precautions that you should observe when servicing
a vehicle. These general precautions apply to many of the service procedures described in this manual, and they
will not necessarily be repeated with each procedure to which they apply.
WARNING:

Whenever raising a vehicle for service, be sure to follow the instructions under ªVEHICLE LIFTING
POINTSº on SECTION 0A.

When it is necessary to do service work with the engine running, make sure that the parking brake
is set fully and the transmission is in Neutral (for manual transmission vehicles) or Park (for automatic
transmission vehicles). Keep hands, hair, clothing, tools, etc. away from the fan and belts when the
engine is running.

When it is necessary to run the engine indoors, make sure that the exhaust gas is forced outdoors.

Do not perform service work in areas where combustible materials can come in contact with a hot
exhaust system. When working with toxic or flammable materials (such as gasoline and refrigerant),
make sure that the area you work in is well-ventilated.

To avoid getting burned, keep away from hot metal parts such as the radiator, exhaust manifold, tail-
pipe, muffler, etc.

New and used engine oil can be hazardous. Children and pets may be harmed by swallowing new or
used oil. Keep new and used oil and used engine oil filters away from children and pets.
Continuous contact with used engine oil has been found to cause [skin] cancer in laboratory animals.
Brief contact with used oil may irritate skin. To minimize your exposure to used engine oil, wear a
long-sleeve shirt and moisture-proof gloves (such as dishwashing gloves) when changing engine oil.
If engine oil contacts your skin, wash thoroughly with soap and water. Launder any clothing or rags
if wet with oil, recycle or properly dispose of used oil and filters.

Make sure the bonnet is fully closed and latched before driving. If it is not, it can fly up unexpectedly
during driving, obstructing your view and resulting in an accident.
CAUTION:

Before starting any service work, cover fenders, seats and
any other parts that are likely to get scratched or stained dur-
ing servicing. Also, be aware that what you wear (e.g, but-
tons) may cause damage to the vehicle's finish.

When performing service to electrical parts that does not re-
quire use of battery power, disconnect the negative cable of
the battery.

tive cable first and then the positive cable. When reconnect-
ing the battery, connect the positive cable first and then the
negative cable, and replace the terminal cover.

When removing parts that are to be reused, be sure to keep
them arranged in an orderly manner so that they may be rein-
stalled in the proper order and position.

Whenever you use oil seals, gaskets, packing, O-rings, lock-
ing washers, split pins, self-locking nuts, and certain other
parts as specified, be sure to use new ones. Also, before
installing new gaskets, packing, etc., be sure to remove any
residual material from the mating surfaces.

Make sure that all parts used in reassembly are perfectly
clean.

When use of a certain type of lubricant, bond or sealant is
specified, be sure to use the specified type.

COMPRESSION SYSTEM DIAGNOSIS
Compressor troubles are mainly following three types: gas leakage, noise and insufficient pressure.
Compressor gas leakages in most cases develop from the shaft seal. When detecting gas leakage, always use
a leak tester. If a small amount of oil seeps out from the shaft seal, there is no necessity of replacing the seal. The
shaft seal has been designed to allow a small amount of oil to leak out for lubricating purpose. Thus, the shaft seal
should be replaced only when a large amount of compressor oil is leaking out or when gas leakage is discovered
by using gas tester.
In regard to noise and insufficient pressure, repairs should be made only after diagnosing the trouble properly.

REFRIGERANT RECOVERY, EVACUATION AND CHARGING
WARNING:

Your eyes should not be exposed to refrigerant (liquid).
Any liquid Refrigerant-134a escaping by accident shows a temperature as low as approx. ± 6C
(42.8F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a seri-
ous injury. To protect your eyes against such accident, it is necessary to always wear goggles. Should
it occur that HFC-134a (R-134a) strikes your eye(s), consult a doctor immediately.
± DO NOT USE YOUR HAND TO RUB THE AFFECTED EYE(S). INSTEAD, use quantities of fresh cold
water to splash it over the affected area to gradually raise temperature of such area above freezing
point.
± Obtain proper treatment as soon as possible from a doctor or eye specialist.

Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.

Refrigerant must not be handled near where welding or steam cleaning is performed.

Refrigerant should be kept at a cold and dark place. It should never be stored where a high tempera-
ture is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle (including
trunk room).

Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazardous
to health.

ALWAYS CARRY AIR BAG (INFLATOR) MODULE
WITH TRIM COVER (AIR BAG OPENING) AWAY
FROM BODY.
10B-58 AIR BAG SYSTEM
LIVE (UNDEPLOYED) AIR BAG (INFLATOR) MODULES
Special care is necessary when handling and storing a live (unde-
ployed) air bag (inflator) modules.
The rapid gas generation produced during deployment of the air
bag could cause the air bag (inflator) module, or an object in front
of the air bag (inflator) module, to be thrown through the air in the
unlikely event of an accidental deployment.
WARNING:
Never attempt to measure the resistance of the air bag (in-
flator) modules (driver and passenger). It is very dangerous
as the electric current from the tester may deploy the air
bag.

Never attempt disassembly of the air bag (inflator) modules.

If any abnormality is found, be sure to replace it with new one as
an assembly.

When an abnormality is noted as existing in the live (undeployed)
air bag (inflator) module, be sure to deploy it before discarding it.

When grease, cleaning agent, oil, water, etc., got on the air bag
(inflator) modules (driver and passenger), wipe it off immediately
with a dry cloth.

If air bag (inflator) module was dropped from a height of 90 cm (3
ft) or more, it should be replaced with a new one as an assembly.
WARNING:

For handling and storage of a live air bag (inflator) module,
select a place where the ambient temperature below 65
C
(150
F), without high humidity and away from electric
noise.

When carrying a live air bag (inflator) module, make sure
the bag opening is pointed away from you. In case of an
accidental deployment, the bag will then deploy with mini-
mal chance of injury. Never carry the air bag (inflator)
module by the wires or connector on the underside of the
module.
Otherwise, personal injury may result.

WARNING:
When placing a live air bag (inflator) module on bench or
other surface, always face the bag up, away from the sur-
face. As the live passenger air bag (inflator) module must be
placed with its bag (trim cover) facing up, place it on the
workbench with a slit or use the workbench vise to hold it
securely at its lower mounting bracket.
It is also prohibited to place anything on top of the trim cov-
er and stack air bag (inflator) modules.
This is necessary so that a free space is provided to allow
the air bag to expand in the unlikely event of accidental de-
ployment.
Otherwise, personal injury may result.
LIVE (INACTIVATED) SEAT BELT PRETENSIONERS
Special care is necessary when handling and storing a live (inacti-
vated) seat belt pretensioners.
Also, when the seat belt pretensioners activate, gas is generated
and the seat belt is retracted into the retractor quickly.
Note, therefore, that if they activate accidentally, the seat belt pre-
tensioners and other object(s) around them may be thrown through
the air.
WARNING:
Never attempt to measure the resistance of the seat belt pre-
tensioners. It is very dangerous as the electric current from
the tester may activate pretensioner.
