HDA is designed to help detect vehicles and lanes ahead, help maintain distance from the vehicle ahead, maintain the set speed, and keep the vehicle between the lanes while driving on certain highways.
***
When HDA is activated and the proper conditions are met, the Instrument Cluster indicator
will illuminate green. If the conditions are not met, HDA will be in standby mode and the indicator light
will illuminate white. When in operation, and if both lanes are recognized, the Instrument Cluster will show the lanes illuminated white and the HDA indicator illuminated green
. 
When HDA is operating, your vehicle will stop if the vehicle ahead of you stops. Also, if the vehicle ahead of you starts moving within approximately 30 seconds after the stop, your vehicle will start to move as well.
If the driver takes their hands off the Steering Wheel for several seconds, a warning message will appear on the Instrument Cluster and an audible warning will sound. If hands on the Steering Wheel are not detected, HDA will cancel.
