Hyundai Elantra MD/UD: Key reminder warning chime (if equipped)
Without smart key
If the driver’s door is opened while the ignition key is left in the ignition switch (ACC or LOCK position), the key reminder warning chime will sound. This helps prevent you from locking your keys in the vehicle. The chime sounds until the key is removed from the ignition switch or the driver’s door is closed.
With smart key
If the driver’s door is opened while the smart key is in the vehicle with the engine start/stop button in ACC, the key reminder warning chime will sound. The chime sounds until the driver’s door is closed.
