This advanced safety system is designed to alert you, and may apply the brakes, if it detects a potential frontal collision with another vehicle. Using an integrated camera and laser or radar to help detect other vehicles in front of you, the Pre-Collision System (PCS) 21 can prompt you to take action using audio and visual alerts if it determines a frontal collision is likely. If you notice the potential collision and apply the brakes, PCS may apply additional force using Brake Assist (BA). 20 If you don’t brake in time, PCS may automatically apply the brakes for you, helping to minimize the likelihood of a frontal collision or reduce its severity.
