• 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 adjustment
screw.
NOTE:
Access adjustment screw from underneath front bumper. Turn screw
clockwise to raise pattern and c ounterclockwise 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. Adjust front fog lamps using adjusting screw so that the top edge of the high intensity zone is 200 mm (7.9 in) below the height of
the fog lamp centers as shown.
• When performing adjustment, if necessary, cover the head-lamps and opposite fog lamp.

2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Procedures without Cowl Top CoverINFOID:0000000005149591
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
General PrecautionsINFOID:0000000005149592
• Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any inflam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or ot her enclosed area, be sure to prop-
erly ventilate the area before working with hazardous materials.
Do not smoke while working on the vehicle.
• Before jacking up the vehicle, apply wheel chocks or other tire blocks to the wheels to prevent t he vehicle from moving. After jack-
ing up the vehicle, support the vehicle weight with safety stands at
the points designated for proper lifting before working on the vehi-
cle.
These operations should be done on a level surface.
• When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.

< PRECAUTION >
PRECAUTIONS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. If an improper
connection is attempted, discharging and contamination may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC134a (R-134a) and specified
oils have been used with the scale. If the scale controls refrigerant
flow electronically, the hose fitting must be 1/2”-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder's top valve
when filling the cylinder with refrigerant. Also, the accu racy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.

2. Measure the inner diameter of oil pump body to brazed portion
(position 6) using suitable tool.
3. Calculate the clearance using the following formula. • (Clearance) = (Inner diameter of oil pump body) - (Outer diameter of inner rotor)
Regulator Valve Clearance
Check regulator valve to oil pump cover clearance using the following formula.
• (Clearance) = D
1 (Valve hole diameter) - D2 (Outer Diameter of
valve)
CAUTION:
• Coat regulator valve with engine oil.
• Check that it falls smoothly into the regulator valve hole by its
own weight.
ASSEMBLY
Installation is in the reverse order of removal.
NOTE:
Install the inner rotor and outer rotor with the punched marks on the
oil pump cover side.
