PCW
FORWARD COLLISION ALERT
UEU
The Forward Collision Alert system may help to avoid or reduce the
harm caused by front-end crashes. When approaching a vehicle ahead
too quickly, FCA provides a red flashing alert on the windshield and
rapidly beeps or pulses the driver seat. FCA also lights an amber visual
alert if following another vehicle much too closely. FCA detects
vehicles within a distance of approximately 60m (197 ft) and operates
at speeds above 8 km/h (5 mph).
Warning FCA is a warning system and does not apply the brakes.
When approaching a slower-moving or stopped vehicle ahead too
rapidly, or when following a vehicle too closely, FCA may not provide
a warning with enough time to help avoid a crash. It also may not
provide any warning at all. FCA does not warn of pedestrians, animals,
signs, guardrails, bridges, construction barrels, or other objects. Be
ready to take action and apply the brakes. FCA can be disabled with
either the FCA steering wheel control or, if equipped, through vehicle
personalization. .
Detecting the Vehicle Ahead FCA warnings will not occur unless the FCA
system detects a vehicle ahead. When a vehicle is detected, the
vehicle ahead indicator will display green. Vehicles may not be
detected on curves, highway exit ramps, or hills, due to poor visibility;
or if a vehicle ahead is partially blocked by pedestrians or other
objects. FCA will not detect another vehicle ahead until it is
completely in the driving lane.
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.
Note: ' Safety or driver assistance features are no substitute for the driver's responsibility to operate the vehicle in a safe manner. The driver should remain attentive to traffic, surroundings and road
conditions at all times. Visibility, weather, and road conditions may affect feature performance. Read the vehicle's owner's manual for more important feature limitations and information.

AUTOMATIC BRAKING
The brakes may be applied automatically in potential collision
situations to help reduce damage or help avoid collisions with
vehicles directly ahead.
When the system detects a vehicle ahead in your path that is
traveling in the same direction that you may be about to crash into,
it can provide a boost to braking or automatically brake the vehicle.
This can help avoid or lessen the severity of crashes when driving
in a forward gear. Depending on the situation, the vehicle may
automatically brake moderately or hard. This forward automatic
braking can only occur if a vehicle is detected. This is shown by the
Forward Collision Alert.
To set the Low Speed Forward Automatic Braking and Forward
Collision Alert systems to Alert and Brake, Alert, or Off, go to
Settilngs>Vehicle> Collision/Detection Systems>Forward Collision System.
