Inspection
The AEB ON/OFF switch is set in the USM (user setting menu); the factory default is ON. If ALL ON is selected, the ON state is kept as the default and does not reflect driver settings until the next ALL ON. If the ESC function is turned off, the AEB function is deactivated.- The AEB ON/OFF setting is in USM (User Setting Menu) and is enabled by default.
- When ALL is activated, activation remains, however driver settings will not be saved the next time ALL is activated.
- When VDC is turned off, AEB is also turned off.

| No. | Procedure | Description |
| 1 | Sensor Installation | • Install the radar sensor in the correct position on the vehicle bumper. (Check the bracket and radar for damage.) |
| 2 | Keep the vehicle stationary. | • Place the vehicle on a lift or on level ground so that it is horizontal relative to the ground. |
| 3 | Vehicle Operation | • Make sure the vehicle interior is empty. (including the luggage compartment). |
| • Check that the front of the radar is clean. | ||
| • Check the suspension and the permissible tire pressure. | ||
| • Check that the radar sensor is installed and connected correctly. | ||
| 4 | Vertical Angle Calibration (with Level Gauge) | • Use a digital inclinometer to measure the alignment. If necessary, adjust the screw to calibrate the angle. (Vertical angle tolerance: ±1.5° or less.) |
| 5 | Horizontal Angle Calibration (Driving) | 1) Turn on the power. (The red light should be on.) |
| 2) Use the GDS diagnostic equipment and start the adjustment. | ||
| 3) After starting, drive the vehicle at a speed of 50 km/h or higher for five minutes. | ||
| 4) If the alignment is completed while driving, the warning lamp on the instrument cluster will go off. | ||
| 6 | Check whether the alignment is complete. | • Alignment is completed by automatic horizontal alignment. (If the warning lamp comes on after alignment is complete, check the bracket and vehicle body for damage.) |
