PRECAUTIONS
General Precautions EAS000PH
l Do 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.
l Before 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.
l When removing a heavy component such as the engine or transaxle/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.
l Before starting repairs which do not require battery power: Turn off ignition switch. Disconnect the negative battery terminal.
l If the battery terminals are disconnected, recorded memory of radio and each control unit is erased.
l To prevent serious burns: Avoid contact with hot metal parts. Do not remove the radiator cap when the engine is hot.
l Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner.
l Do 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.
l Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly.
l Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones.
l Replace inner and outer races of tapered roller bearings and needle bearings as a set.
l Arrange the disassembled parts in accordance with their assembled locations and sequence.
l Do not touch the terminals of electrical components which use microcomputers (such as ECM). Static electricity may damage internal electronic components.
l After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
l Use only the fluids and lubricants specified in this manual.

l Use approved bonding agent, sealants or their equivalents when required. l Use tools and recommended special tools where specified for safe and efficient service repairs. l When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks. l Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate cov- ers. Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
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 Three Way Catalyst EAS000PI
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To prevent this, follow the instructions. l Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst. l When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary. l Do 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 Fuel EAS000PJ
GASOLINE ENGINE (REGULAR GASOLINE)
l Three way catalyst equipped models ... use unleaded gasoline with an octane rating of at least 91 RON (research octane number). CAUTION: Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. l Except for the above models ... use unleaded or leaded gasoline with an octane rating of at least 88 RON (research octane number). Use unleaded gasoline if instructed on the fuel filler lid.
GASOLINE ENGINE (PREMIUM GASOLINE)
Use premium unleaded gasoline with an octane rating of at least 95 RON (research octane number). If pre- mium unleaded gasoline is not available, regular unleaded gasoline with an octane rating of at least 91 RON (research octane number) can be used. However, for maximum vehicle performance, the use of premium unleaded gasoline is recommended. 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.
DIESEL ENGINE
l For Europe model; use diesel fuel of at least 50 cetane. l Except for Europe model; use diesel fuel of at least 45 cetane. If two types of diesel fuel are available, use summer or winter fuel properly according to the following temper- ature conditions.

l To reinstall the rubber hose securely, make sure that hose inser- tion length and orientation is correct. (If tube is equipped with hose stopper, insert rubber hose into tube until it butts up against hose stopper.)
HOSE CLAMPING
l If 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. l Discard old clamps; replace with new ones.
l After installing plate clamps, apply force to them in the direction of the arrow, tightening rubber hose equally all around.
Precautions for Engine Oils EAS000PN
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
l Avoid prolonged and repeated contact with oils, particularly used engine oils. l Wear protective clothing, including impervious gloves where practicable. l Do not put oily rags in pockets. l Avoid contaminating clothes, particularly underpants, with oil. l Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu- larly. l First aid treatment should be obtained immediately for open cuts and wounds. l Use barrier creams, applying them before each work period, to help the removal of oil from the skin. l Wash 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. l Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin. l If skin disorders develop, obtain medical advice without delay. l Where practical, degrease components prior to handling.

PRECAUTIONS
l Where 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
For the service site in UK, 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 Pollution for small burners of less than 0.4 MW. If in doubt check with the appropriate local authority and/or manufac- turer of the approved appliance. 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.
Precautions for Air Conditioning EAS000PO
Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to ATC/MTC section “HFC-134a (R-134a) Service Procedure”, “REFRIGERANT LINES” for specific instructions.

HOW TO USE THIS MANUAL
Detectable Lines and Non-Detectable Lines
In some wiring diagrams, two kinds of lines, representing wires, with different weight are used.
l A line with regular weight (wider line) represents a “detectable line for DTC (Diagnostic Trouble Code)”. A “detectable line for DTC” is a circuit in which ECM can detect its malfunctions with the on board diagnostic system.
l A line with less weight (thinner line) represents a “non-detect- able line for DTC”. A “non-detectable line for DTC” is a circuit in which ECM cannot detect its malfunctions with the on board diagnostic system.
