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)
[1] : 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.
NOTICE
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.
System settings
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.
WARNING
For your safety, change the Settings after parking the vehicle at a safe location.
System operation
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
System malfunction
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.

High Beam Assist may not work properly in the following situations:
- Light from a vehicle is not detected because of lamp damage, or because it is hidden from sight, etc.

- The road conditions are bad such as being wet, iced or covered with snow.
- A vehicle suddenly appears from a curve.
- The vehicle is tilted from a flat tire or is being towed.
- Light from a vehicle is not detected because of exhaust fume, smoke, fog, snow, etc.
For more details on the limitations of the front view camera, refer to "Forward Collision-Avoidance Assist (FCA)" section in chapter 7.
