On winding roads, FCA may not detect a
vehicle ahead. You could crash into a vehicle
ahead of you. Do not rely on FCA on
winding roads.

When weather limits visibility, such as in fog,
rain, or snow, FCA performance is limited.
There may not be enough warning distance to
the vehicle in front of you. Do not rely on
FCA in low visibility conditions.

Alerting the Driver
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 5-2 for more information.
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 FCA alert symbol will
flash and a warning beep
will sound when driver
action may be required.
