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.

ENGINE OIL LEVEL
●Before starting the engine, put vehicle horizontally then check
the engine oil level. If the engine is already started, stop it and
allow 10 minutes before checking.
●Check that the engine oil level is within the range shown in the
figure.
●If it is out of range, adjust it.
ENGINE OIL APPEARANCE
●Check the engine oil for white turbidity or remarkable contamination.
●If the engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Find the cause and repair.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
●Oil pan
●Oil pan drain plug
●Oil pressure switch
●Oil filter
●Oil cooler
●Intake valve timing control cover and intake valve timing control solenoid valve
●Front cover
●Mating surface between cylinder block and cylinder head
●Mating surface between cylinder head and rocker cover
●Crankshaft oil seal.
OIL PRESSURE CHECK
WARNING:
●Be careful not to burn yourself, as the engine oil is hot.
●Engine oil pressure check should be done in “ Parking
position” (A/T model) or “Neutral position” (M/T model).
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove the undercover.
3. Remove the oil pressure switch to connect the oil pressure
gauge.
4. After warming up the engine, check that oil pressure corre-
sponding to the engine speed is produced.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
5. After checking, install the oil pressure switch as follows.
a. Remove old sealant adhering to the switch and engine.
b. Apply thread sealant.
Use Genuine Liquid Gasket or equivalent.
