Driving and Operating Detecting the Vehicle Ahead 9-33 { Warning FCA does not provide a warning to help avoid a crash, unless it detects a vehicle. FCA may not detect a vehicle ahead if the FCA sensor is blocked by dirt, snow, or ice, or if the windshield is damaged. It may also not detect a vehicle on winding or hilly roads, or in conditions that can limit visibility such as fog, rain, or snow, or if the headlamps or windshield are not cleaned or in proper condition. Keep the windshield, headlamps, and FCA sensors clean and in good repair. Tailgating Alert The green vehicle ahead indicator will turn amber if following another vehicle much too closely. Collision Alert The green vehicle ahead indicator will appear when a vehicle is detected ahead. Whenever this indicator does not appear, FCA will not respond. The indicator may disappear on curves, highway exit ramps, or hills, or due to poor visibility. The FCA system will not detect another vehicle ahead until it is completely in the driving lane. When your vehicle approaches another vehicle too rapidly, this red FCA display will flash and eight beeps will sound from the front. When this occurs, the brake system prepares for driver braking to occur more rapidly. Continue to apply the brake pedal as the driving situation dictates. Selecting the Alert Timing Press the collision alert button, [, on the center stack to set the alert timing to far, medium, near, or off. The first button press shows the current control setting on the DIC.
