Aiming Adjustment

NKS002OK

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 adjusting screw.

1.

Set the distance between the screen and the center of the front
fog lamp lens as shown at left.

2.

Turn front fog lamps ON.
