*a	5 m (16.4 ft.)
*b	6 m (19.7 ft.)
*c	4 m (13.1 ft.)
*d	2 m (6.56 ft.)
*e	3 m (9.84 ft.)
*f	1.5 m (4.92 ft.)
*g	2.5 m (8.2 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 that have a height of 50 mm (1.97 in.) or less do not affect adjustment within 2 m (6.56 ft.) from the front of the vehicle.

(b) Check the levelness of the ground.

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

*a	3 m (9.84 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, No. 1 radiator grille seal 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.

(g) Check that the radiator grille and front bumper assembly are securely installed, and that there is no damage or deformation around the installation areas. If any abnormalities are found, repair or replace parts as necessary.

2. ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY HORIZONTALLY

HINT:

The vertical axis deviation can only be checked and cannot be adjusted.

(a) Adjust SST (reflector) height.

- Set the reflector so that its center is 612 mm (2.01 ft.) above the ground.
for Hatchback, GR:
- Set the reflector so that its center is 627 mm (2.06 ft.) above the ground.
for TMC Made Sedan without Illumination:
- Set the reflector so that its center is 618 mm (2.03 ft.) above the ground.
for TMC Made Sedan with Illumination:
- Set the reflector so that its center is 640 mm (2.10 ft.) above the ground.

Center Line

Target Panel

Adjust the position of the laser line marker so that the laser beam is aligned with the center line of the target panel.

Extend a tape measure at least 3000 mm (9.84 ft.) in length from point B, and set the tape measure in place.

*a	Tape Measure

At a distance of 3000 mm (9.84 ft.) from point B, apply an approximately 200 mm (7.87 in.) piece of tape alongside the tape measure, and mark point C.

Tape

(4) When not using a laser line marker:

Using tape and a string, create a line that connects point B to point A and extends at least 3000 mm (9.84 ft.) beyond the front center point of the vehicle.

*a	String	*b	Tape
*c	3000 mm (9.84 ft.)	-	-

HINT:

Make sure the string is taut when securing it with tape.
