CAUTION / NOTICE / HINT

CAUTION:

Radiofrequency radiation exposure information:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be kept with minimum distance of 20 cm (7.87 in.) between the radiator (antenna) and your body at all times during adjustment.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

PROCEDURE

1. PREPARATION FOR MILLIMETER WAVE RADAR SENSOR ASSEMBLY ADJUSTMENT

(a) Park the vehicle on a level surface where the area in front of the vehicle shown in the illustration is free of metal objects.

*a	2.5 m (8.2 ft.)
*b	2 m (6.6 ft.)
	Do not place any metal objects in this area
	Do not place metal objects with a height of more than 50 mm (1.97 in.) in this area

HINT:

Metal objects with a height of 50 mm (1.97 in.) or less placed within the area shown in the illustration will not affect the adjustment.

(b) Check the levelness of the ground.

(1) Check the levelness of the ground at the 3 points shown in the illustration.

*a	1.5 m (4.92 ft.)
	Levelness Check Point

(2) Place the level on each levelness check point and check that the air bubble of the level is centered.

(d) Clean the front emblem or millimeter wave radar sensor assembly.

(e) Visually inspect the front of the vehicle.

HINT:

Confirm that there is no damage or deformation.

(f) Visually inspect the front bumper assembly, radiator grille and stays.

HINT:

Confirm that there is no damage or deformation.

2. ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY

(a) Adjust SST (flat surface target) height.

*a	SST (Flat Surface Target)
*b	SST (Panel Stand)

(1) Check that SST (flat surface target) has no damage or deformation.

SST: 09870-60100

SST: 09870-60110

(2) Check that SST (flat surface target) is assembled correctly.

(3) Check that SST (flat surface target) has no looseness or wobble.

(4) Loosen the top and bottom handles of SST (panel stand), and while checking the included scale, adjust the height of SST (flat surface target) as shown in the illustration so that its height reference line is at the same height as the millimeter wave radar sensor assembly, then re-tighten the top and bottom handles.

HINT:

Adjust SST (flat surface target) so that its center is aligned with the millimeter wave radar sensor assembly (center of emblem).
Height adjustment can be performed using the scale included with SST (flat surface target).

Reference Value:

666 mm (2.18 ft.)

*a	Handle
*b	Scale
*c	Height Reference Line

(b) Place SST (flat surface target).

(1) Hang a weight with a pointed tip from the center of the rear emblem, and mark the rear center point of the vehicle (point A) on the ground.

*a	String	*b	Weight
*c	Center	-	-

HINT:

Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.

(2) Hang a weight with a pointed tip from the center of the front emblem, and mark the front center point of the vehicle (point B) on the ground.

*a	String	*b	Weight
*c	Center	-	-

HINT:

Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.

(3) Using tape and a string, create a line that connects point B to point A and extends at least 1500 mm (4.92 ft.) beyond the front center point of the vehicle.

*a	String	*b	Tape
*c	1500 mm (4.92 ft.)	-	-

HINT:

Make sure the string is taut when securing it with tape.
Lightly flick the string with your fingers several times to confirm that the string is aligned with point B.

(4) Mark point C (SST (flat surface target) placement position) at a position 1500 mm (4.92 ft.) from point B.

(5) Position SST (panel stand) so that it is aligned with the target position line and the mark-off line is aligned with point C as shown in the illustration.

*a	SST (Panel Stand)	*b	Mark-off Line
*c	Reference Line	-	-

NOTICE:

Make sure that the mark-off lines of the SST (panel stand) are aligned with the reference line.
