Aiming Adjustment

EKS00FUG

For details, refer to the regulations in your area.

NOTE:
If vehicle front body has been repaired and /or the headlamp assembly has been replaced, check headlamp
aiming.

●

Before performing aiming adjustment, check the following:

–

Confirm headlamp aiming switch is set to "0" (zero) position.

–

Ensure all tires are inflated to correct pressure.

–

Place vehicle and screen on level surface.

–

Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant and engine oil filled to correct level, and fuel tank full.

–

Confirm spare tire, jack and tools are properly stowed.

–

Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.

–

Use adjusting screw to perform aiming adjustment

Aiming Chart

NOTE:

●

By regulation, no means for horizontal aim adjustment is provided from the factory; only vertical aim is
adjustable.

●

Basic illuminating area for evaluation and/or adjustment should be within range shown on aiming chart. 

1.

Use adjustment screw to perform aiming adjustment.

●

Cover the opposite lamp and ensure fog lamps, if equipped, are turned off.

CAUTION:

Do not tighten adjustment screw beyond specified torque or damage may occur.

2.

Adjust beam pattern until cut-off line (top edge of illumination area) is positioned at the specified height off
ground. Measure cut-off line within distance J on H-line. See aiming chart.
