Using the Pre-Collision Assist System WARNING The Pre-Collision Assist system’s brake support reduces collision speed only if you brake your vehicle before any collision. As in any typical braking situation, you must press your brake pedal. You can adjust the warning system's sensitivity through your information display. See General Information (page 104). Note: When possible, the manufacturer recommends using the highest sensitivity setting. If warnings are too frequent, you can reduce your system's sensitivity. Reduced sensitivity causes fewer and later system warnings. See General Information (page 104).
