Note

If the pre-crash safety city sensor cannot correctly recognize the area in front of the vehicle due to bad weather (dense fog, etc.) or obstructions, the automatic high beam indicator light in the combination meter assembly may not illuminate, and the automatic high beam system may not operate.
If the pre-crash safety city sensor is not installed correctly, the automatic high beam system may not operate.

*: The condition of the pre-crash safety city sensor can be checked on the Data List.
