●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.)

●If the engine speed is out of specified range, check battery liquid for proper gravity. Check engine
speed again with normal battery gravity.
●If compression pressure is below minimum value, check valve clearances and parts associated with
combustion chamber (Valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure compression pressure again.
●If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug
hole of the cylinder to re-check it for compression.
–If the added engine oil improves the compression, the piston rings may be worn out or damaged. Check
the piston rings and replace if necessary.
–If the compression pressure remains at low level despite the addition of engine oil, the valves may be
malfunctioning. Check the valves for damage. Replace the valve or valve seat accordingly.
●If two adjacent cylinders have respectively low compression pressure and their compression remains
low even after the addition of engine oil, the gaskets are leaking. In such a case, replace the cylinder
head gaskets.
8. Install spark plug, ignition coil and harness connectors.

EXHAUST MANIFOLD AND TURBOCHARGER
TROUBLE DIAGNOSIS OF TURBOCHARGER
Preliminary check:
●Check that the engine oil level is between MIN and MAX of the dipstick. (When the engine oil amount is
more than MAX, the engine oil flows into the inlet duct through the blow-by gas passage, and the turbo-
charger is misjudged failure.)
●Ask the customer if he/she always runs the vehicle in idle engine speed to cool the engine oil down after
driving.
●Replace the turbocharger assembly when any malfunction is found after unit inspections specified in the
table below.
●If no malfunction is found after the unit inspections, judge that the turbocharger body has no failure. Check
the other parts again.

INSPECTION AFTER INSTALLATION
●Before starting engine check the levels of engine coolant, lubrications and working engine oils. If less than
required quantity, fill to the specified level.
●Before starting engine, bleed air from fuel piping. Refer to FL-16, "Air Bleeding" .
●Run engine to check for unusual noise and vibration.
●Warm up engine thoroughly to make sure there is no leakage of engine coolant, lubricants, working
engine oil, fuel and exhaust gas.
●Bleed air from passages in pipes and tubes of applicable lines.
