·

Make sure that the engine coolant is filled to the specified level.

·

Inflate the tires to the appropriate pressure.

·

Unload the trunk and vehicle, ensuring that the spare tire, tools and jack are in their original positions.

·

Bounce the vehicle at the corners up and down to stabilize the suspension.

·

·

Place the vehicle in a location that is dark enough to clearly observe the cutoff line. The cutoff line is a distinct line, below which light from the headlights can be observed and above which it cannot.

·

Place the vehicle at a 90° angle to a wall.

·

Create a 10 m (32.8 ft.) distance between the vehicle (center marks of the headlights) and the wall.

·

Make sure that the vehicle is on a level surface.

·

Position the front wheels straight ahead.

·

Bounce the vehicle up and down to settle the suspension.


NOTICE:

A distance of 10 m (32.8 ft.) between the vehicle (center marks of the headlights) and the wall is necessary for proper aim adjustment. If sufficient space is not available, secure a distance of exactly 3 m (9.84 ft.) to allow for checking and adjustment of the headlight aim. (The size of the target zone will change with the distance, so follow the instructions in the illustration.)

i.

H Line (Headlight height):

Draw a horizontal line across the screen so that it passes through the center marks. The H line should be at the same height as the center marks of the headlights.


ii.

V LH Line, V RH Line (Center mark position of left-hand (LH) and right-hand (RH) headlights):

Draw 2 vertical lines so that they intersect the H line at each center mark (aligned with the center marks of the headlights).



Hide 4.INSPECT HEADLIGHT AIMING

a.

Cover the headlight on the opposite side to prevent light from the headlight that is not being inspected from affecting the headlight aiming inspection.

NOTICE:

Do not keep the headlight covered for more than 3 minutes. The headlight lens is made of synthetic resin, which may melt or be damaged due to excessive heat.



b.

Start the engine.


c.

Turn on the headlights and check if the cutoff line for each low beam matches the preferred cutoff line in the illustration.

a.

Adjust the aim vertically:

i.

Adjust the aim of each headlight to the specified range by turning each aiming screw (A) with a screwdriver.

NOTICE:

The final turn of the aiming screw should be made in the clockwise direction. If the screw is tightened excessively, loosen it and then retighten it, so that the final turn of the screw is in the clockwise direction.


HINT:
·

Since the low beam headlight and the high beam headlight are a unit, if the aim on the low beam is correct, the high beam should also be correct. However, check both beams to make sure.

·

If it is not possible to correctly adjust headlight aim, check the headlight unit and headlight unit lens installation.

·

Confirm the direction of rotation of the aiming screw by observing it while it is being adjusted. Due to the position of the screwdriver, the direction of rotation of the adjusting screw can be different than the direction of rotation of the screwdriver being used to adjust it.
