Kia Cadenza: Highway Driving Assist (HDA) / Warning Message

Hands-off warning

Keep hands on steering wheel

If the driver takes their hands off the steering wheel for several seconds while HDA is activated, the system will warn the driver.

✽ NOTICE

If the steering wheel is held with a light grip, the message may appear because HDA may not recognize that the driver has their hands on the steering wheel.

WARNING

The warning message may appear late according to road conditions. Therefore, always have your hands on the steering wheel while driving.

Highway Driving Assist (HDA) system canceled

If the driver still does not have their hands on the steering wheel after the message "Keep hands on steering wheel", HDA will be canceled. However, if Lane Following Assist is reactivated manually by the driver, Highway Driving Assist will reactivate.
