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	5 m (16.4 ft.)
*b	6 m (19.7 ft.)
*c	4 m (13.1 ft.)
*d	2 m (6.56 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	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.

(c) Adjust the tire inflation pressure to the specified pressure.

Click here (d) Clean the radiator grill garnish or millimeter wave radar sensor assembly.

(d) Clean the radiator grill garnish or millimeter wave radar sensor assembly.

(e) Visually inspect the front of the vehicle.

HINT:

Confirm that there is no damage or deformation.

(f) Check that the radiator grill garnish and millimeter wave radar sensor assembly is clean and there is no dirt or snow covering them.

(g) Visually inspect the front bumper cover, radiator grille sub-assembly and stays.

HINT:

Confirm that there is no damage or deformation.

2. ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY

(a) Adjust SST (reflector) height.

(1) Adjust SST (reflector) so that the center of SST (reflector) is the same height as the millimeter wave radar sensor assembly.

HINT:

Make sure to align the center of SST (reflector) with the millimeter wave radar sensor assembly (the center of the emblem).

Reference Value:

Radiator Grille Sub-assembly	Specified Condition
for Type A	945 mm (3.10 ft.)
for Type B	974 mm (3.19 ft.)
for Type C	871 mm (2.86 ft.)

SST: 09870-60000

09870-60010

SST: 09870-60040

*a	SST (reflector)

(b) Place SST (reflector).

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

*a	String	*b	Weight
*c	Bilateral Symmetry	-	-

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 radiator grille garnish, and mark the front center point of the vehicle (point B) on the ground (placement position).

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 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.
Lightly flick the string with your fingers several times to confirm that the string is aligned with point B.

(4) Mark point C (SST (reflector) placement position) at a position 3000 mm (9.84 ft.) from point B.

(5) Place SST (reflector) at point C.

NOTICE:

Close all of the doors.
Ensure that nobody enters the adjustment area during the adjustment.
Do not move or shake the vehicle during adjustment (do not get in or out of the vehicle).
During the procedure, do not enter the adjustment area.
Do not turn off the Techstream or ignition switch.

(1) Connect the Techstream to the DLC3.

(2) Turn the ignition switch to ON.

(3) Turn the Techstream on and turn the cruise control system on using the cruise control main switch (ON/OFF button).

(4) Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Adjustment.

(5) According to the display on the Techstream, press "Next".

(6) Perform the adjustment according to the display on the Techstream.

NOTICE:

If an error code is displayed, perform troubleshooting according to the following table, then perform the adjustment again.

Error No.	Error Description	Cause of Error	Action to be Taken
1	No target abnormality	SST (reflector) is placed incorrectly. The radiator grille sub-assembly or millimeter wave radar sensor assembly is covered by dirt or snow.	Place SST (reflector) in the correct position. (See page 2. MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY (b) Place SST (reflector))
			Clean the radiator grill garnish and radiator grille sub-assembly or millimeter wave radar sensor assembly.
