Aiming AdjustmentAKS007MV
PREPARATION BEFORE ADJUSTING
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1. Keep all tires inflated to correct pressures.
2. Place vehicle on flat surface.
3. Set that there is no-load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant, engine oil filled up to correct level and full fuel tank.
LOW BEAM AND HIGH BEAM
1. Turn headlamp low beam on.
2. Use adjusting screws to perform aiming adjustment.

Aiming AdjustmentAKS007CT
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.

Keep all tires inflated to correct pressure.

Place vehicle on level ground.

See 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 seat.
Adjust aiming in the vertical direction by turning the adjusting screw.
1. Set the distance between the screen and the center of the fog
lamp lens as shown at left.
2. Turn front fog lamps ON.
3. 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 at left.

When performing adjustment, if necessary, cover the head-
lamps and opposite fog lamp.

ENGINE OIL LEVEL
NOTE:
Before starting engine, check engine oil level. If engine is already started, stop it and allow 10 minutes before
checking.
1. Put vehicle horizontally.
2. Pull out oil level gauge and wipe it clean.
3. Insert oil level gauge and make sure engine oil level is within the
range shown in the figure.
4. If it is out of range, adjust it.
NOTE:
When checking engine oil level, insert oil level gauge with its tip
aligned with oil level gauge guide on cylinder head. (In figure, air
cleaner case and air duct are removed.)
ENGINE OIL APPEARANCE

Check engine oil for white turbidity or heavy contamination.

If engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

Oil cooler

Water pump cover

Chain tensioner cover

Intake valve timing control cover and intake valve timing control solenoid valve

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Mating surface between front timing chain case and rear timing chain case

Mating surface between rear timing chain case and cylinder block and cylinder head

Crankshaft oil seal (front and rear)

INSTALLATION
Note to the following, and install in the reverse order of removal.
2WD Model
Align cutout on oil cooler with protrusion on oil pan (upper).
AW D M od e l
Align cutout on oil cooler with protrusion on oil filter bracket.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level and the engine coolant level and add engine oil and engine coolant. Refer to
LU-7, "
ENGINE OIL" and Refer to CO-11, "ENGINE COOLANT" .
2. Start engine, and check there is no leaks of engine oil or engine coolant.
3. Stop engine and wait for 10 minutes.
4. Check the engine oil level and the engine coolant level again. Refer to LU-7, "
ENGINE OIL" and Refer to
CO-11, "
ENGINE COOLANT" .

ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If the engine is already started,
stop it and allow 15 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

Check engine oil for white turbidity or heavy contamination.

If 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 oil leakage around the following area.

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

Oil cooler

Intake valve timing control cover

Intake valve timing control solenoid valve

Front cover

Chain tensioner cover

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Crankshaft oil seals (front and rear)
OIL PRESSURE CHECK
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Oil pressure check should be done in “Parking position”.
1. Check engine oil level. Refer to LU-25, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.
