0A-6 GENERAL INFORMATION
CAUTION:
Even when the accident was light enough not to cause air
bags to activate, be sure to inspect system parts and other
related parts according to instructions under ªRepair and
Inspection Required after an Accidentº in SECTION 10B.
When servicing parts other than air bag system, if shocks
may be applied to air bag system component parts, re-
move those parts beforehand.
When handling the air bag (inflator) modules (driver and
passenger), seat belt pretensioners (driver and passen-
ger) or SDM, be careful not to drop it or apply an impact to
it. If an excessive impact was applied (e.g., dropped from
a height of 91.4 cm (3 feet) or more), never attempt disas-
sembly or repair but replace it with a new one.
When grease, cleaning agent, oil, water, etc. has got onto
air bag (inflator) modules (driver and passenger) or seat
belt pretensioners (drive and passenger), wipe off im-
mediately with a dry cloth.
Air bag wire harness can be identified easily as it is cov-
ered with a yellow protection tube. Be very careful when
handling it.
When an open in air bag wire harness, damaged wire har-
ness, connector or terminal is found, replace wire har-
ness, connectors and terminals as an assembly.
Do not apply power to the air bag system unless all com-
ponents are connected or a diagnostic chart requests it,
as this will set a diagnostic trouble code.
Never use air bag system component parts from another
vehicle.
When using electric welding, be sure to temporarily dis-
able air bag system referring to ªDisabling Air Bag Sys-
temº described in ªService Precautionsº under ªOn-Ve-
hicle Serviceº in SECTION 10B.
Never expose air bag system component parts directly to
hot air (drying or baking the vehicle after painting) or
flames.
WARNING / CAUTION labels are attached on each part of
air bag system components. Be sure to follow the instruc-
tions.
After vehicle is completely repaired, perform ªAir Bag
Diagnostic System Checkº described in ªDiagnosisº in
SECTION 10B.

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.

CAUTION:
When changing engine coolant, use mixture of 50% wa-
ter and 50% ANTIFREEZE / ANTICORROSION COOLANT
for the market where ambient temperature falls lower
than ±16C (3F) in winter, and mixture of 70% water and
30% ANTIFREEZE / ANTICORROSION COOLANT for the
market where ambient temperature doesn't fall lower
than ±16C (3F).
Even in a market where no freezing temperature is antici-
pated, mixture of 70% water and 30% ANTIFREEZE / AN-
TICORROSION COOLANT should be used for the pur-
pose of corrosion protection and lubrication.
ITEM 1-6
Exhaust System Inspection
WARING:
To avoid danger of being burned, do not touch exhaust sys-
tem when it is still hot. Any service on exhaust system
should be performed when it is cool.
When carrying out periodic maintenance, or the vehicle is raised for
other service, check exhaust system as follows:
Check rubber mountings for damage, deterioration, and out of
position.
Check exhaust system for leakage, loose connections, dents and
damages.
If bolts or nuts are loose, tighten them to specification.
Check nearby body areas for damaged, missing, or misposi-
tioned parts, open seams, holes, loose connections or other de-
fects which could permit exhaust fumes to seep into the vehicle.
Make sure that exhaust system components have enough clear-
ance from the underbody to avoid overheating and possible dam-
age to the floor carpet.
Any defects should be fixed at once.
