PRECAUTIONS AND PREPARATION

SGI231

General Precautions

●

Do not operate the engine for an extended period of time without proper exhaust ventilation. Keep the workarea well ventilated and free ofany inflammable materials. Special care should be taken when handling any inflammable or poisonous materials, such as gasoline, refrigerant gas, etc. When working in a pit or other enclosed area, be sure to properly ventilate the area before working with hazardous materials. Do not smoke while working on the vehicle.

●

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.

●

When removing a heavy component such as the engine or transaxle, be careful not to lose your balance and drop it. Also, do not allow it to strike adjacent parts, especially the brake tubes and master cylinder.

●

Before starting repairs which do not require battery power: Turn off ignition switch. Disconnect the negative battery terminal.

SEF289H

SGI233

●

To prevent serious burns: Avoid contact with hot metal parts. Do not remove the radiator cap when the engine is hot.

●

Before servicing the vehicle: Protect fenders,upholstery and carpeting withappropriate covers. Take caution that keys, bucklesor buttons do not scratchpaint.

PRECAUTIONS AND PREPARATION

AGI011

Precautions for Multiport Fuel Injection System or Engine Control System

●

Before connecting or disconnecting any harness connector for the multiport fuel injection system or ECM: Turn ignition switch to OFF position. Disconnect negative battery terminal; otherwise, there may be damage to ECM.

●

Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure.

●

Be careful not to jar components such as ECM and mass air flow sensor.

Precautions for Three Way Catalyst

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:

●

Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.

●

When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary.

●

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 inflammable material. Keep inflammable material off the exhaust pipe and 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. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.

HEALTH PROTECTION PRECAUTIONS

●

Avoid prolonged and repeated contact with oils, particularly used engine oils.

●

Wear protective clothing, including oil resistant gloves when practicable.

●

Do not put oily rags in pockets.

●

Avoid contaminating clothes, particularly underclothing, with oil.

●

Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regularly.

●

First aid treatment should be obtained immediately for open cuts and wounds.

●

Use barrier creams, applying them before each work period, to help the removal of oil from the skin.

●

Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Preparations containing lanolin replace the natural skin oils which have been removed.

●

Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.

●

If skin disorders develop, obtain medical advice without delay.

●

Where practicable, degrease components prior to handling.

●

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.

DETECTABLE LINES AND NON-DETECTABLE LINES

In some wiring diagrams, two kinds of lines with different thicknesses are used to represent wires.

●

A line with regular thickness (wider line) represents a ‘‘detectable line for DTC (Diagnostic Trouble Code)’’. A ‘‘detectable line for DTC’’ is a circuit in which ECM can detect malfunctions with the on board diagnostic system.

●

A line with less thickness (thinner line) represents a ‘‘non-detectable line for DTC’’. A ‘‘non-detectable line for DTC’’ is a circuit in which ECM cannot detect malfunctions with the on board diagnostic system.
