	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.

Adjust the tire inflation pressure to the specified pressure. (Click here)

Clean the front emblem or millimeter wave radar sensor assembly.

Visually inspect the front of the vehicle.

HINT:

Confirm that there is no damage or deformation.

Visually inspect the front bumper assembly, radiator grill and stays.

HINT:

Confirm that there is no damage or deformation.

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).

   HINT:

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

   Error No.	Error Description	Cause of Error	Action to be Taken
   1	No target abnormality	The reflector is placed incorrectly. The front emblem or millimeter wave radar sensor assembly is covered by dirt or snow. The beam axis of the millimeter wave radar sensor assembly is outside the automatic correction range.	Place the reflector in the correct position. (See page 2. ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY (b) Place the reflector)
   			Clean the front emblem or millimeter wave radar sensor assembly.
   			Check the installation condition of the front bumper assembly and radiator grill.
   			Manually change the beam axis. (See page 3. MANUALLY CHANGE BEAM AXIS OF MILLIMETER WAVE RADAR SENSOR ASSEMBLY)
   2	Target distance abnormality	The reflector is placed incorrectly.	Place the reflector in the correct position. (See page 2. ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY (b) Place the reflector)
   3	Plural targets abnormality	There is a reflective object near the reflector. A person entered the adjustment area.	Remove any reflective objects.
   			Ensure that nobody enters the adjustment area during the adjustment. (See page 1. PREPARATION FOR MILLIMETER WAVE RADAR SENSOR ASSEMBLY ADJUSTMENT)
   4	Target move abnormality	The reflector was moved out of position or shaking during the adjustment due to wind. A person entered the adjustment area.	Place the reflector in the correct position. (See page 2. ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY (b) Place the reflector)
   			Perform adjustment in an area with no wind.
   			Place the reflector in the correct position. (See page 2. ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY (b) Place the reflector)
