●Use approved bonding agent, sealants or their equivalents when required.
●Use tools and recommended special tools where specified for safe and efficient service repairs.
●When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
●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 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.
● Remove the propeller shaft.
● Use 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.
●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 flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precautions for FuelEAS000P9
GASOLINE ENGINE
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.
DIESEL ENGINE
Diesel fuel of at least 50 cetane.
If two types of diesel fuel are available, use summer or winter fuel properly according to the following temper-
ature conditions.
●Above –7°C (20°F) ... Summer type diesel fuel.
●Below –7°C (20°F) ... Winter type diesel fuel.
SGI234

GI-6
PRECAUTIONS
CAUTION:
●Do not use home heating oil, gasoline or other alternate fuels in your diesel engine. The use of
those can cause engine damage.
●Do not use summer fuel at temperatures below –7°C (20°F). The cold temperatures will cause wax
to form in the fuel. As a result, it may prevent the engine from running smoothly.
●Do not add gasoline or other alternate fuels to diesel fuel.
Precautions for Multiport Fuel Injection System or Engine Control SystemEAS000FT
●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 Turbocharger (If Equipped)EAS000FU
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean sup-
ply of oil flowing through the turbocharger and to follow all required
maintenance instructions and operating procedures.
●Always use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
●Avoid accelerating engine to a high rpm immediately after start-
ing.
●If engine had been operating at high rpm for an extended period
of time, let it idle for a few minutes prior to shutting if off.
Precautions for HosesEAS000FV
HOSE REMOVAL AND INSTALLATION
●To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.
●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
●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.
●Discard old clamps; replace with new ones.
●After 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
●Avoid prolonged and repeated contact with oils, particularly used engine oils.
●Wear protective clothing, including impervious gloves where practicable.
●Do not put oily rags in pockets.
●Avoid contaminating clothes, particularly underpants, with oil.
●Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.
●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). Prepa-
rations 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 practical, 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.
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.
Precautions for Air Conditioning EAS000FX
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.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
●Do not apply excessive shock to the control unit by dropping or
hitting it.
●Be careful to prevent condensation in the control unit due to
rapid temperature changes and do not let water or rain get on it.
If water is found in the control unit, dry it fully and then install it in
the vehicle.
●Be careful not to let oil to get on the control unit connector.
●Avoid cleaning the control unit with volatile oil.
●Do not disassemble the control unit, and do not remove the
upper and lower covers.
●When using a DMM, be careful not to let test probes get close to
each other to prevent the power transistor in the control unit
from damaging battery voltage because of short circuiting.
●When checking input and output signals of the control unit, use
the specified check adapter.

2-pole Lift EAS000FJ
WARNING:
When lifting the vehicle, open the lift arms as wide as possible and ensure that the front and rear of
the vehicle are well balanced.
