Aiming Adjustment
EKS00P7Y
For details, refer to the regulations in your state.
Before performing aiming adjustment, check the following.
1. Ensure all tires are inflated to correct pressure.
2. Place vehicle and screen on level surface.
3. Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant and engine oil filled to correct level, and fuel tank full.
4. Confirm spare tire, jack and tools are properly stowed.
LOW BEAM AND HIGH BEAM
NOTE:
Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
1. Turn headlamp low beam ON.
2. Use adjusting screws to perform aiming adjustment.
lFirst tighten the adjusting screw all the way and then make adjustment by loosening the screw.
If the vehicle front body has been repaired and/or the headlamp assembly has been replaced, check
aiming. Use the aiming chart shown in the figure.

Aiming AdjustmentEKS00P4D
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.
lKeep all tires inflated to correct pressure.
lPlace vehicle on level surface.
lSee that vehicle is unloaded (except for full levels of coolant, engine oil and fuel, and spare tire, jack, and
tools). Have the driver or equivalent weight placed in driver's seat.
Adjust aiming in the vertical direction by turning the adjustment
screw.
NOTE:
Use a Phillips screwdriver to adjust. Turn screw clockwise to raise
pattern and counterclockwise to lower pattern.
1. Set the distance between the screen and the center of the fog
lamp lens as shown.
2. Turn front fog lamps ON.
3. Remove front portion of fender protector(s) for adjusting screw
access. Refer toEI-22, "
Removal and Installation of Front
Fender Protector".
4. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is 100 mm (4 in) below the height of
the fog lamp centers as shown.
lWhen performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.

ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
lCheck engine oil for white turbidity or heavy contamination.
lIf engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
lOil pan (lower and upper)
lOil pan drain plug
lOil pressure switch
lOil filter and oil filter bracket
lOil cooler
lOil pump housing
lVa c u u m p u m p
lCylinder head rear cover assembly
lFront and rear chain cases
lMating surface between cylinder block and cylinder head
lMating surface between cylinder head and rocker cover
lFront and rear oil seals
lTurbocharger
lOil tube connecting parts from turbocharger
ENGINE OIL PRESSURE CHECK
WARNING:
lBe careful not to burn yourself, as the engine oil may be hot.
lOil pressure check should be done in “Neutral position”(M/T models) or “Parking position”(A/T
models).
1. Check the engine oil level. Refer toLU-5, "
ENGINE OIL LEVEL".
2. Remove engine undercover front and engine undercover middle. Refer toEI-15, "
FRONT BUMPER".

OIL COOLER
3. Remove mounting nuts (2) of fuel filter (1), and move it aside
with its hoses connected. Temporarily secure it with a rope to
avoid putting load on its hose.
4. Disconnect water hoses from oil cooler.
lWhen removing oil cooler only, pinching water hoses near oil cooler to prevent engine coolant spilling.
CAUTION:
lPerform this step when engine is cold.
lDo not spill engine coolant on drive belts.
5. Loosen connecting bolt and remove oil cooler.
CAUTION:
Do not spill engine oil and engine coolant to rubber parts such as drive belts and engine mounting
insulator.
6. Remove water hoses and water connector, as necessary.
INSPECTION AFTER REMOVAL
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary,
replace oil cooler.
INSTALLATION
Installation is the reverse order of removal.
lMake sure that no foreign objects are adhering to the installation planes of oil cooler or oil filter bracket.
lTighten the connecting bolt after aligning the stopper on the oil
filter bracket side with protrusion of oil cooler (1).
lInstall fuel filter (1), and tighten mounting nuts (2) to the speci-
fied torque.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level and the engine coolant level, and add engine oil and engine coolant. Refer to
LU-5, "
ENGINE OIL"andCO-7, "ENGINE COOLANT".
