CAUTION:
Radiofrequency radiation exposure information:
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.

(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 grill and stays.
HINT:
Confirm that there is no damage or deformation.
2. 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. HINT: Make sure to align the center of SST (reflector) with the millimeter wave radar sensor (the center of the emblem). Reference Value: 611 mm (2.00 ft.) SST: 09870-60000 09870-60010 SST: 09870-60040 |
|
(b) Place SST (reflector).
(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 | *d | 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 front emblem, and mark the front center point of the vehicle (point B) on the ground.
*a | String | *b | Weight |
*c | Center | *d | Bilateral Symmetry |
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:
(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.
(c) Front Beam Axis Adjustment:
NOTICE:
(1) Connect the Techstream to the DLC3.
(2) Turn the engine switch on (IG) (for Gasoline Model).
(3) Turn the power switch on (IG) (for HV Model).
(4) Turn the Techstream on.
(5) Enter the following menus: Body Electrical / Front Radar Sensor / Utility / Front Beam Axis Adjustment.
Body Electrical > Front Radar Sensor > Utility Tester Display |
---|
