Advanced driver assistance: helpful safety net, not a chauffeur
Automatic braking and lane support can help, but names and capabilities vary—and the human driver remains responsible.
What can help
Features such as forward-collision warning, automatic emergency braking, blind-spot warning and lane-departure warning can add useful information or intervention when conditions are within the system’s design.
What can go wrong
Cameras and radar can be affected by weather, dirt, road markings, glare or damage. Feature names may sound more capable than the system actually is.
- Read the owner’s manual instead of relying on the marketing name
- Keep sensors and cameras clean
- Confirm calibration after windshield, alignment or collision work
- Stay ready to steer and brake at all times
Buying used
Verify that warning lights are off, all sensors are present and previous collision repairs included required calibration. A system that appears to operate may still be misaligned.
