Hyundai Tucson: High Beam Assist (HBA)
High Beam Assist will automatically adjust the headlamp range (switches between high beam and low beam) depending on the brightness of detected vehicles and certain road conditions.
Detecting sensor (Front view camera)
 : Front view camera
The front view camera is used as a detecting sensor to detect ambient light and brightness while driving.
Refer to the picture above for the detailed location of the detecting sensor.
Always keep the front view camera in good condition to maintain optimal performance of High Beam Assist.
For more details on the precautions of the front view camera, refer to "Forward Collision-Avoidance Assist (FCA)" section in chapter 7.
With the engine on, select 'Lights → High Beam Assist (or HBA (High Beam Assist))' from the Settings menu to turn on High Beam Assist and deselect to turn off the system.
For your safety, change the Settings after parking the vehicle at a safe location.
Display and control
After selecting 'High Beam Assist' in the Settings menu, High Beam Assist will operate by following the procedure below.
- Place the headlamp switch in the AUTO position and push the headlamp lever towards the instrument cluster. The High Beam Assist ( ) indicator light will illuminate on the cluster and the system will be enabled.
- When the system is enabled, high
beam will turn on when vehicle
speed is above 25mph (40km/h).
When vehicle speed is below 15mph (25km/h), high beam will not turn on.
- The High Beam ( ) indicator light will illuminate on the cluster when high beam is on.
When High Beam Assist is operating, if the headlamp lever or switch is used, the system operates as follow:
- If the headlamp lever is pulled
towards you when the high beam
is off, the high beam will turn on
without High Beam Assist canceled.
When you let go of the headlamp lever, the lever will move to the middle and the high beam will turn off.
- If the headlamp lever is pulled towards you when the high beam is on by High Beam Assist, low beam will be on and the system will turn off.
- If the headlamp switch is placed from AUTO to another position (headlamp/position/off), High Beam Assist will turn off and the corresponding lamp will turn on.
When High Beam Assist is operating, high beam switches to low beam if any of the following conditions occur:
- When the headlamp of an oncoming vehicle is detected.
- When the tail lamp of a vehicle in front is detected.
- When the headlamp or tail lamp of a motorcycle or a bicycle is detected.
- When the surrounding ambient light is bright enough that high beams are not required.
- When streetlights or other lights are detected.
System malfunction and limitations
When High Beam Assist is not working properly, the 'Check High Beam Assist (HBA) system' or 'Check HBA (High Beam Assist system' warning message will appear and warning light will illuminate on the cluster. We recommend that the system be inspected by an authorized HYUNDAI dealer.
