2. Use adjusting screws to perform aiming adjustment.

First tighten the adjusting screw all the way and then make adjustment by loosening the screw.
If the vehicle front body has been repaired and/or the headlamp assembly has been replaced, check
aiming. Use the aiming chart shown in the figure.

Adjust headlamps so that main axis of light is parallel to cen-
ter line of body and is aligned with point P shown in illustra-
tion.

Figure to the right shows headlamp aiming pattern for driving
on right side of road; for driving on left side of road, aiming
pattern is reversed.

Dotted lines to point P in illustration show center of head-
lamp.

Basic illuminating area for adjustment should be within the
range shown at right. Adjust headlamps accordingly.
CAUTION:
Be sure aiming switch is set to “0” when preforming aiming
adjustment.
Aiming Adjustment for Driving LampEKS00AP6

Turn the aiming adjusting screw to adjust.

For positions of the adjustment screws and direction to turn,
refer to the figures.

When adjusting for right or left side, adjust upper and lower
adjustment screws at the same time.
PREPARATION BEFORE ADJUSTING
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1. Keep all tires inflated to correct pressures.
2. Place vehicle on level ground.
3. 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, full fuel tank and spare tire, jack, and tools."H" : Horizontal center line of headlamps
