Aiming AdjustmentINFOID:0000000001704409
The front 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 surface.
• 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, spare tire, jack and tools are properly stowed.
Adjust aiming in the vertical direction by turning the adjusting screw (A).
1. Set the distance (C) between the screen and the center of front
fog lamp lens (E) as shown.
2. Turn front fog lamps (1) to ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone (A) is as shown.
NOTE:
When performing adjustment, if necessary, cover the headlamps
and opposite front fog lamp.
