2. Select “AUTO AIM”.
3. Confirm following.
a. The target should be accurately placed.
b. The vehicle should be stopped.
4. Select “Start” to perform aiming.
CAUTION:
Never Select “Start” when the target is not placed.
5. Input “Dh”, and then select “Start”. NOTE:
Check the value “Dh”. Refer to "VEHICLE HEIGHT CHECK".
CAUTION:
Never change “Ht” and “Dt”.
6. Check it display item.
a. “Normally Completed” is displayed, then selecting “Completion”.
b. Perform the following services when displa yed “SUSPENSION” or “ABNORMALLY COMPLETED”.

7. Check if “Normally Completed” is displayed and close the aiming adjustment procedure by selecting
“End”.
Check After The Adjustment
1. Perform self-diagnosis of LDW camera unit. Refer to DI-81, "CONSULT-III Function (LDW)".
2. Test the LDW system operation by running test. Refer to DI-71, "
Action Test".
Dh [mm] = (Hfl + Hfr)
