NOTE: If the millimeter wave radar unit is removed or replaced, or if a millimeter wave radar unit aiming error occurs, aim the millimeter wave radar unit. Incomplete aiming, an aiming error, or dust or dirt on the radar unit surface causes the adaptive cruise control (ACC) indicator to come on.

Millimeter wave radar unit aiming incomplete: DTC 107
Millimeter wave radar unit aiming error: DTC 63
Millimeter wave radar unit or emblem surface is contaminated with dust, dirt, ice, or snow: DTC 105

Before Aiming:

Aiming the millimeter wave radar unit requires the HDS.
Clean the surface of the millimeter wave radar unit.
Make sure the vehicle has no aftermarket suspension.
Make sure all the tire sizes are correct and that their pressure is correct.
Make sure the fuel tank is full.
Remove all baggage from the vehicle except the spare tire and the tool kit.
Make sure the steering wheel is straight ahead, and do not turn it after setting the vehicle.
Shift transmission lever into P, and apply the parking brake.
Make sure the upper grille and the front bumper are installed correctly.
Park the vehicle on level ground in a wide open space to avoid misadjusting caused by reflecting objects. The space needs to be 32.8 ft (10 m) in front, 13.1 ft (4 m) in width and 4.9 ft (1.5 m) in height.
If NO TARGET is not indicated even when there are no objects for 33 ft (10 m) in front vehicle, check for reflecting objects in front of the vehicle.

NOTE: When the millimeter wave radar unit is adjusted on ground that has more than 1 degree of horizontal slope (drainage slope), the vertical aiming cannot be adjusted correctly. Check the levelness of the ground, and adjust the angle of millimeter wave radar unit to be parallel to that of the ground, lay a ruler (at least 12") or other flat straight object on the ground and put the level on top to confirm the levelness of the ground.
