Millimeter Wave Radar Aiming (Integrated Driver Support System / Dynamic Aiming) (2025): Adjustment

How to use this service information .

NOTICE: 

• When working with a vehicle equipped with the electronic air suspension, be sure to set it to the leveling off mode to prevent unexpected operation. Refer to the Electronic Air Suspension System Service Precautions - Refer to: Electronic Air Suspension System Connector Fitting Precautions or Electronic Air Suspension System Service Precautions for the procedure.
• The following describes the details of the Integrated Driver Support System. Refer to Driving Support System Description for the function applied to your vehicle - Refer to: Driving Support System Description(Integrated Driver Support System (Camera and Five Radars)) (2025) or Driving Support System Description(Integrated Driver Support System) (2025) or Driving Support System Description (2022 2023 2024) .

NOTE: 

• Before millimeter wave radar aiming, refer to Vehicle Conditions that require Millimeter Wave Radar Aiming .
• There are two methods of aiming for the millimeter wave radar: Dynamic radar aiming and static radar aiming, and do either one aiming procedure.
• The millimeter wave radar aiming is the automatic learning of vertical/horizontal reference points using the HDS. The millimeter wave radar has a self-diagnosis function, and if the aiming fails or is incomplete, a DTC will be stored.

Precautions before dynamic radar aiming: 

Set up the vehicle:

• The warning indicators (amber) of the ACC, LKAS, CMBS, and Safety Support are blinking or off.
• There are no DTCs for the integrated driver support system stored. (Except DTC P2583-54 - Refer to: DTC Troubleshooting: P2583-54 (2025) or DTC Troubleshooting: P2583-54 (2022 2023 2024) )

  NOTE:  If a DTC is indicated, troubleshoot the DTC first.

• If the vehicle you are aiming was involved in a collision or if you suspect the wheel alignment is out of specifications, you must perform a wheel alignment prior to aiming the millimeter wave radar.
• Make sure the suspension has not been modified.
• Make sure all tire sizes are correct and that their pressures are correct.
• Make sure that there are no stains, dust, or dirt on the front "A" emblem/radar cover.
• The removed parts are installed.
• Remove cargo from the vehicle except the tool kit and the spare tire (if equipped).
• Make sure that all doors are closed.

Prerequisite for Aiming:

• Vehicle speed 19 - 50 mph (30 - 80 km/h) or more (constant speed), straight driving a road

Recommended environment:

• Driving at a constant speed of 25 - 50 mph (40 - 80 km/h) or more
• In weather without rain, snow, or fog
• Roads with the scattering structures of different heights such as utility poles and signboards
• Roads with few guardrails and many straight lines, such as urban areas and industrial complexes
• Roads that are not tunnels or bridges

Standard time for completing the aiming:

• Aiming will be completed within 15 - 25 minutes in the recommended environment.

NOTICE: 

• If the prerequisites do not match during aiming that is put on hold, and resumed when the conditions are match.
• Aiming is possible even in the rain, but it may take longer to complete.
• If the driving environment is out of the recommended environment, perform the static radar aiming.
• If dynamic radar aiming is not completed after 30 minutes, perform dynamic radar aiming again in the recommended environment.

Prepare these items: 

• HDS

When performing dynamic aiming for radar and camera: 

NOTE:  This vehicle has the method of simultaneously performing the dynamic aiming of the multipurpose camera and the millimeter wave radar. In that case, select "Dynamic Aiming for Radar and Camera" from "Adjustment" on the HDS.

NOTICE: 

Before dynamic aiming for radar and camera, refer to "Precautions before dynamic radar aiming" and "Precautions before dynamic camera aiming - Refer to: Multipurpose Camera Aiming (2022 2023 2024)  or Multipurpose Camera Aiming(Integrated Driver Support System (Camera and Five Radars) / Static Aiming) (2025)  or Multipurpose Camera Aiming(Integrated Driver Support System / Static Aiming) (2025)  or Multipurpose Camera Unit Update (2022 2023 2024)  or Vehicle Conditions that require Multipurpose Camera Aiming(Integrated Driver Support System) (2025)  or Multipurpose Camera Unit Update(Integrated Driver Support System) (2025)  or Multipurpose Camera Aiming(Integrated Driver Support System (Camera and Five Radars) / Dynamic Aiming) (2025)  or Multipurpose Camera Aiming(Integrated Driver Support System / Dynamic Aiming) (2025)  or Multipurpose Camera Unit Update(Integrated Driver Support System (Camera and Five Radars)) (2025)  or Vehicle Conditions that require Multipurpose Camera Aiming(Integrated Driver Support System (Camera and Five Radars)) (2025) ".

1. Dynamic Radar - Aim

   Preconditions 

   • HDS Connected

     NOTE:  Troubleshoot any DTCs first before proceeding. If DTC P2583-54 - Refer to: DTC Troubleshooting: P2583-54 (2025) or DTC Troubleshooting: P2583-54 (2022 2023 2024) is indicated, proceed with the aiming procedure.

   Procedure 

   1. Select the following menu buttons on the HDS screen in sequence.

   • Driving Support (System Selection Menu)
   • Integrated Driver Support System
   • Adjustment
   • Dynamic Radar Aiming

   2. Perform the Dynamic Radar Aiming with the HDS and drive the vehicle at a constant speed with reference of the prerequisite conditions and recommended environment. The warning indicators (a) and the aiming indicators (b) are displayed on the MID as follows. (Figure 1 and 2)

   NOTICE: 

   • Drive the vehicle on the road with safety.
   • If the warning indicator or the aiming indicator status changes, stop the vehicle in a safe place and check the status on the HDS screen.

   3. When the warning indicator or the aiming indicator status changes, stop the vehicle in a safe place and confirm the millimeter wave radar aiming completion on the HDS screen.

   NOTICE:  If the aiming fails, record the failure code displayed on the HDS screen.

   4. Turn the vehicle to the OFF (LOCK) mode.

   5. Turn the vehicle to the ON mode.

   Result 

   Confirm the warning indicators are off on the MID. (Figure 3)

   • If the aim fails for some reason during the aiming, or if it is stopped halfway, an error code will be displayed on the HDS. Refer to \"Failure Codes\" and repair or replace parts as necessary. After the work, you must start the aiming procedure again.
