Cleaning the System {CAUTION: FCA may not detect and warn soon enough to stationary or slow-moving vehicles or other objects ahead of you. You could crash into an object ahead of you. Do not rely on FCA when approaching stationary or slow-moving vehicles or other objects. The radar can become blocked by snow, ice, or dirt. If so, you may need to turn off the engine and clean the lens. See "Cleaning the System" under Adaptive Cruise Control on page 173. Flash-to-Pass This feature lets you use the high-beam headlamps to signal the driver in front of you that you want to pass. The flash-to-pass feature will only work with the headlamps on. It does not work with Daytime Running Lamps (DRL). Pull and hold the turn signal lever toward you to use. If the headlamps are on high beam, they will switch to low beam. To return to high beam, push the lever away from you. Unnecessary Alerts FCA may occasionally provide alerts that you consider unnecessary. It could respond to a turning vehicle ahead of you, guard rails, signs, and other stationary objects. This is normal operation, your vehicle does not need service. Other Messages There are three messages that may appear on the Driver Information Center (DIC). They are CLEAN RADAR, RADAR CRUISE NOT READY and SERVICE RADAR CRUISE.
