Why do red lights sometimes flash on my windshield?

Your vehicle may be trying to help you avoid a potential collision.

Here's how:

If your car is equipped with the Collision warning with brake support feature, it will trigger a flashing row of red lights on your windshield and sound an alarm, if it senses you're rapidly approaching traffic in front of you.
If you continue to draw closer to vehicles traveling more slowly in the same direction, the system will pre-charge your brakes to help you stop as quickly as possible, if necessary.*
