Alerting the Driver The FCA alert symbol will flash and a warning beep will sound when driver action may be required. Detecting the Vehicle Ahead The vehicle ahead symbol, located next to the FCA symbol, will only appear when a vehicle ahead of you is detected in your path. If this symbol does not appear, or disappears briefly, FCA will not respond to vehicles you may see ahead. The symbol may disappear on curves, highway exit ramps, or hills. Also, when another vehicle enters the same lane as you, the FCA system will not detect the vehicle until it is completely in your driving lane. The alert symbol will flash when: • Your vehicle is approaching another vehicle too quickly. • Your vehicle is following a vehicle ahead of you much too closely. See Defensive Driving on page 296 for more information. {CAUTION: When the Adaptive Cruise Control radar is blocked by snow, ice, or dirt, it may not detect a vehicle ahead. FCA may not help you avoid a collision under these conditions. Do not use FCA when the radar is blocked by snow, ice, or dirt. Keep your radar clean. See "Cleaning the System" under Adaptive Cruise Control on page 173. 164
