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.

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

Unnecessary Alerts
FCA may occasionally provide alerts that you consider

objects. This is normal operation, your vehicle does not
need service.
