PRECAUTIONS
General Precautions
EAS000FQ
lDo not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.
lBefore jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.
lWhen removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
lBefore starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
lIf the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
lTo prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
lDispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.
lDo not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.
lClean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
lReplace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.
lReplace inner and outer races of tapered roller bearings and needle bearings as a set.
lArrange the disassembled parts in accordance with their assembled locations and sequence.
lDo not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
lAfter disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

PRECAUTIONS
GI-5
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.
lBefore servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
WA RN ING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precautions for All Mode 4´4 SystemEAS000GQ
Even if the 2WD mode is selected, the All mode 4´4 system occasionally changes from 2WD to 4WD auto-
matically depending on the driving conditions.
When spinning the front wheels by running the engine with the front wheels jacked up or mounted on the free
rollers / or a chassis dynamometer, be careful because the vehicle may suddenly move due to the driving
force from the rear wheels.
To avoid personal injury and vehicle damage, use one of the following methods when working with the front
wheels drive force and spinning freely.
lRemove the propeller shaft.
lUse free rollers / chassis dynamometer designed for 4WD vehicles.
Precautions for Three Way CatalystEAS000FR
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
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 FuelEAS000FS
Use unleaded gasoline with an octane rating of at least 95 (RON).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.

HOSE CLAMPING
lIf old rubber hose is re-used, install hose clamp in its original
position (at the indentation where the old clamp was). If there is
a trace of tube bulging left on the old rubber hose, align rubber
hose at that position.
lDiscard old clamps; replace with new ones.
lAfter installing plate clamps, apply force to them in the direction
of the arrow, tightening rubber hose equally all around.
Precautions for Engine OilsEAS000FW
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
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 regu-
larly.
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). Prepa-
rations containing 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 practical, 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
Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste dis-
posal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal
facilities.
It is illegal to pour used oil on to the ground, down sewers or drains, or into water sources.
The regulations concerning pollution vary between regions.
