If there is a problem with the system, a message will appear for several seconds. If the problem does not go away, the LKA system malfunction indicator will illuminate.

The LKA malfunction indicator (yellow) illuminates if the LKA system is not operating properly. Have your vehicle checked by an authorized HYUNDAI dealer.
If a problem occurs with the system, do one of the following:
- Turn the system off after the engine is switched off, then turn it on again.
- Check that the ignition switch is in the ON position.
