The Hyundai IONIQ Hybrid has a number of useful functions that are built into the car. Here's a couple that we find to be useful.
Lane Keeping Assist uses the front camera to monitor the lines of the road. In case of an unintended lane departure, it will warn the driver and can apply counter steering torque to guide the car back to the lane.
Blind-spot Collision Warning monitors the rear corners and, if another vehicle is detected, an amber light alert will appear on the exterior mirrors. If the driver then activates the indicators, an audible signal is emitted in lane change situations in which a vehicle is detected.
So, don't worry if there are short beeping sounds in the car — it's just the car protecting you from possible danger. Drive safe!
