CAUTION:
 Perform this operation in a horizo ntal position where there is a clear view for 5 m (16.4 ft) forward
and 3 m (9.84 ft) wide.
 Place the target in a well-lig hted location. (Poor lighting may make it hard to adjust.)
 The target may not be detected when there is a ligh t source within 1.5 m (4.92 ft) from either side and
within 1 m (3.28 ft) upward/downward from the target.
 Check the location of the sun. (S unlight should not shine directly on the front of the vehicle.)
 The target may not be detected when there is the same pattern of black and white as the target when
the pattern is within 1 m (3.28 ft) from either si de and upward/downward position from the target. (It
is desirable that the vehicle is positioned on the opposite side of a single-color wall.)
1.TARGET SETTING
1. Mark points “A”, “B”, “C” and “D”at the center of the lateral sur- face of each wheels.
NOTE:
Hang a string with a cone from the fender so as to pass through
the center of wheel, and then mark a point at the center of the
lateral surface of the wheel.
2. Draw line “LH” passing through points “A” and “B” on the left side
of vehicle.
NOTE:
Approximately 4 m (13.12 ft) or mo re from the front end of vehi-
cle.

positions 3850 mm (151.57 in) from point “A”.
4. Draw line “RH” passing through points “C” and “D” on the right side of vehicle in the same way as step 2. NOTE:
Approximately 4 m (13.12 ft) or more from the front end of vehicle.
5. Mark point “F” on the line “RH” at the positions 3850 mm (151.57 in) from point “C”.
6. Draw line “FW” passing through the points “E” and “F” on the front side of vehicle.
7. Mark point “X” at the center of point “E” and “F” on the line “FW”.
CAUTION:
Make sure that “E” to “X” is equal to “F” to “X”.
8. Position the center of the ri ght target to point of “X”.

Adjustment)".
Work Procedure (Camera Aiming Adjustment)INFOID:0000000006223737
CAUTION:
Perform the adjustment under unloaded vehicle condition.
1.CHECK VEHICLE HEIGHT
Measure the wheelarch height. Calculate “Dh”.
NOTE:
“Dh” may be calculated as a minus value.
>> GO TO 2.
2.CAMERA AIMING ADJUSTMENT
CAUTION:
Operate CONSULT-III outside the vehic le, and close all the doors. (To retain vehicle attitude appropri-
ately)
1. Select “Work Support” on “L ANE CAMERA” with CONSULT-III.
2. Select “AUTO AIM”.
3. Confirm the following items;
- The target should be accurately placed.
- The vehicle should be stopped.
4. Select “Start” to perform camera aiming. CAUTION:
 Never select “Start” when the target is not accurately placed.
 Wait 5 seconds or more after selecting “Start”.
5. Input “Dh”, and then select “Start”.
CAUTION:
Never change “Ht” and “Dt”.
6. Confirm the displayed item.
- “Normally Completed”: Select “Completion”.
- “SUSPENSION”, “X AIMING NG Y”, “ABNORMALL Y COMPLETED”: Perform the following services.

Check the clearance and the surface height betw een hood and each part by visually and touching.
If the clearance and the surface height are out of spec ification, adjust them according to the procedures
shown below.
Unit: mm (in)
1. Remove hood lock and adjust the surface height of hood, bumper molding and front fender according to
the fitting standard dimension, by rotating hood bumper rubber.
2. Loosen hood hinge mounting nuts on the hood.
3. Adjust the clearance of hood, bumper molding and fr ont fender according to the fitting standard dimen-
sion, for the hood.
4. Temporarily tighten hood lock.
5. Adjust A and B shown in the figure to the following value with hood's own weight by dropping it from approximately 200 mm (7.874 in) height or by pressi ng hood lightly [approximately 29 N (3.0 kg, 6.5lb)].
6. Install as static closing force of hood is 680N (69.0 kg, 502lb) or less.
7. After adjustment, tighten hood hinge mounting nuts to the specified torque. CAUTION:
 Before installing hood hinge, apply anticorrosive agent onto th e mounting surface of the vehicle
body.
 Check hood hinge rotating pa rt for poor lubrication. If necessary, apply body grease.
