0A-4 GENERAL INFORMATION
SERVICING AND HANDLING
WARNING:
Many of service procedures require disconnection of ªAIR
BAGº fuse and all air bag (inflator) module(s) from initiator
circuit to avoid an accidental deployment.
Driver and Passenger Air Bag (Inflator) Modules

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. When placing a live air bag (inflator) module on
a bench or other surface, always face the bag up, away
from the surface. 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. 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.

Never dispose of live (undeployed) air bag (inflator) mod-
ules (driver and passenger). If disposal is necessary, be
sure to deploy them according to deployment procedures
described in SECTION 10B before disposal.

The air bag (inflator) module immediately after deploy-
ment is very hot. Wait for at least half an hour to cool it off
before proceeding the work.

After an air bag (inflator) module has been deployed, the
surface of the air bag may contain a powdery residue. This
powder consists primarily of cornstarch (used to lubri-
cate the bag as it inflates) and by-products of the chemical
reaction. As with many service procedures, gloves and
safety glasses should be worn.

GENERAL INFORMATION 0A-5
WARNING:
SDM

During service procedures, be very careful when handling
a Sensing and Diagnostic Module (SDM). Never strike or
jar the SDM.
Never power up the air bag system when the SDM is not
rigidly attached to the vehicle. All SDM and mounting
bracket fasteners must be carefully torqued and the arrow
must be pointing toward the front of the vehicle to ensure
proper operation of the air bag system.
The SDM could be activated when powered while not rigid-
ly attached to the vehicle which could cause deployment
and result in personal injury.
WARNING:
Driver and Passenger Seat Belt Pretensioners

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

Never carry seat belt pretensioner by wire or connector of
pretensioner. When placing a live seat belt pretensioner
on the workbench or some place like that, be sure not to
lay it with its exhaust hole provided side facing down. It is
also prohibited to put something on its face with an ex-
haust hole or to put a seat belt pretensioner on top of
another. Otherwise, personal injury may result.

Never dispose of live (inactivated) seat belt pretensioners
(driver and passenger). If disposal is necessary, be sure
to activate them according to activation procedures de-
scribed in SECTION 10B before disposal.

The seat belt pretensioner immediately after activation is
very hot. Wait for at least half an hour to cool it off before
proceeding the work.

With many service procedures, gloves and safety glasses
should be worn to prevent any possible irritation of the
skin or eyes.

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.
