WARNING:
When replacing fuel line parts, be sure to observe the following:
lPut a ``CAUTION: INFLAMMABLE'' sign in workshop.
lDo not smoke while servicing fuel system. Keep open flames and sparks away from work area.
lBe sure to disconnect battery ground cable before conducting operations.
lBe sure to furnish workshop with a CO2fire extinguisher.
lDrain fuel from fuel tank and put drained fuel in an explosion-proof container and put lid on
securely.
CAUTION:
lBefore disconnecting fuel hose of ECCS engine model, release fuel pressure from fuel line. Refer
to ``Changing Fuel Filter'' in MA section.
lDo not disconnect any fuel line unless absolutely necessary.
lPlug hose and pipe openings to prevent entry of dust or dirt.
lAlways replace O-ring and clamps with new ones.
lDo not kink or twist hose and tube when they are installed.
lDo not tighten hose clamps excessively to avoid damaging hoses.
lWhen installing fuel check valve, be careful of its designated direction. (Refer to ``EVAPORATIVE
EMISSION SYSTEM'' in EC section.)
lTighten bolts to specified torque.
lAfter installation, run engine and check for fuel leaks at connections.

CAUTION:
lAlways replace exhaust gaskets with new ones when
reassembling. If gasket is left on flange surface, scrape
off completely as shown at left.
lWith engine running, check all tube connections for
exhaust gas leaks, and entire system for unusual noises.
lEnsure that mounting brackets and mounting insulators
are installed properly and free from undue stress.
Improper installation could result in excessive noise or
vibration.
lDiscard any heated oxygen sensor which has been
dropped from a height of more than 0.5 m (19.7 in) onto
a hard surface such as concrete floor; use a new one.

Precautions
lWhen installing rubber parts, final tightening must be
carried out under unladen condition* with tires on
ground.
* Fuel, radiator coolant and engine oil full. Spare tire,
jack, hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake
tubes.
lAfter installing removed suspension parts, check wheel
alignment and adjust if necessary.
lAlways torque brake lines when installing.

lAfter disconnecting vacuum or air hoses, attach a tag to
indicate the proper connection.
lUse only the fluids and lubricants specified in this manual.
lUse approved bonding agent, sealants or their equivalents
when required.
lUse tools and recommended special tools where specified
for safe and efficient service repairs.
lWhen repairing the fuel, oil, water, vacuum or exhaust
systems, check all affected lines for leaks.
lDispose of drained oil or the solvent used for cleaning parts
in an appropriate manner.
WARNING:
To prevent ECM from storing the diagnostic trouble codes,
do not carelessly disconnect the harness connectors which
are related to the ECCS system and TCM (Transmission
Control Module) system. The connectors should be discon-
nected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC section.
Precautions for Multiport Fuel Injection
System or ECCS Engine
lBefore connecting or disconnecting any harness connector
for the multiport fuel injection system or ECM (Engine Con-
trol Module):
Turn ignition switch to ``OFF'' position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
lBefore disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
lBe careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Three Way Catalyst
(If so equipped)
If a large amount of unburned fuel flows into the catalyst, the
catalyst temperature will be excessively high. To prevent this,
follow the instructions below:
lUse unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
lWhen checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
lDo not run engine when the fuel tank level is low, otherwise
the engine may misfire causing damage to the catalyst.
Do not place the vehicle on flammable material. Keep flammable
material off the exhaust pipe and the three way catalyst.
Precautions for Engine Oils
Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
SGI787
PRECAUTIONS
General Precautions (Cont'd)
GI-4

If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
lAvoid prolonged and repeated contact with oils, particularly
used engine oils.
lWear protective clothing, including impervious gloves where
practicable.
lDo not put oily rags in pockets.
lAvoid contaminating clothes, particularly underpants, with oil.
lHeavily soiled clothing and oil-impregnated footwear should
not be worn. Overalls must be cleaned regularly.
lFirst Aid treatment should be obtained immediately for open
cuts and wounds.
lUse barrier creams, applying them before each work period,
to help the removal of oil from the skin.
lWash with soap and water to ensure all oil is removed (skin
cleansers and nail brushes will help). Preparations contain-
ing lanolin replace the natural skin oils which have been
removed.
lDo not use gasoline, kerosine, diesel fuel, gas oil, thinners
or solvents for cleaning skin.
lIf skin disorders develop, obtain medical advice without
delay.
lWhere practicable, degrease components prior to handling.
lWhere there is a risk of eye contact, eye protection should
be worn, for example, chemical goggles or face shields; in
addition an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating
system must meet the requirements of HM Inspectorate of Pol-
lution for small burners of less than 0.4 MW. If in doubt check
with the appropriate local authority and/or manufacturer of the
approved appliance.
Dispose of used oil and used oil filters through authorized waste
disposal contractors to licensed waste disposal sites, or to the
waste oil reclamation trade. If in doubt, contact the local author-
ity for advice on disposal facilities.
It is illegal to pour used oil on to the ground, down sewers or
drains, or into water courses.
The regulations concerning the pollution of the environment
will vary from country to country.
Precautions for Fuel
GASOLINE ENGINE:
Three way catalyst equipped models ... unleaded gasoline of at
least 91 octane (RON)
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the three way catalyst.
Except for the above models ... unleaded or leaded gasoline of
above 88 octane (RON)
Use unleaded fuel if instructed on the fuel filler lid.
