Aiming AdjustmentBKS001P5
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 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 adjustment screw.
1. Set the distance between the screen and the center of the front
fog lamp lens as shown in the figure.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the main
optical axis of the high intensity zone is in the figure.

When performing this adjustment, cover the headlamps and
the opposite front fog lamp, if necessary.
