Blind spot warning alerts you to cars in the blind spots on either side of your vehicle. A small icon—typically in the side-view mirrors—lights up to indicate that it’s unsafe to make a lane change. If you activate your turn signal when a vehicle is in your blind spot, the car safety symbol in the mirror flashes to caution against a lane change and sometimes sounds a warning tone.
Driver-monitoring systems keep track of eye and head movements and driving behavior that indicate you might be drowsy or distracted. If the system senses a problem, it issues a visual and/or audible alert, reminding you to pull over and rest.
Lane departure warning detects painted lines and raised pavement markers to help you stay in your lane. If you drift out of your lane, a beeping sound, flashing icon and/or vibration in the steering wheel will alert you. The car safety warning won’t sound when you have your turn signal activated. Going one step further, lane-keeping assistance detects when you drift out of your lane and gently guides your car back. (It won’t continue to drive your car.)
5 less common ADAS features
Active driving assistance controls a vehicle’s steering, acceleration, and braking and sometimes keeps a vehicle in the center of the lane. It’s not the same as self-driving: You must supervise the feature and still be responsible for driving.
Active parking assistance locates a suitable parking spot and executes many of the steering, shifting, accelerating and braking functions needed to park a car, in some cases with the driver outside the vehicle (called remote parking assistance). The car safety system also helps drivers exit from tight parallel parking spots.
