Unnecessary Alerts
FCA may provide unnecessary
alerts for turning vehicles, vehicles
in other lanes, objects that are not
vehicles, or shadows. These alerts
are normal operation and the
vehicle does not need service.
Cleaning the System
If the FCA system does not seem to
operate properly, cleaning the
outside of the windshield in front of
the camera sensor and the front of
the vehicle may correct the issue.
Active Emergency
Braking System
If the vehicle has Adaptive Cruise
Control (ACC) it also has the Active
Emergency Braking System, which
includes the Automatic Collision
Preparation (ACP) System.
Automatic Collision
Preparation (ACP) System
ACP may help reduce crash
damage by applying the vehicle
’
s
brake system and has a detection
range of approximately 60 m
(197 ft). Braking can only occur if a
vehicle is detected ahead. This is
shown by the FCA vehicle-ahead
indicator being lit. See
Forward
Collision Alert (FCA) System on
page 9-48

Warning
ACP is an emergency crash
preparation feature and is not
designed to avoid crashes. Do
not rely on ACP to brake the
vehicle.
ACP may not:
.
Respond to stopped vehicles,
pedestrians, or animals.
.
Detect a vehicle ahead on
winding or hilly roads.
(Continued)
Warning (Continued)
.
Detect a stopped or
slow-moving vehicle or other
object ahead.
.
Detect a vehicle when
weather limits visibility, such
as in fog, rain, or snow. In
these situations, ACP sensor
performance is limited.
Complete attention is always
required while driving, and you
should be ready to take action
and apply the brakes and/or steer
the vehicle to avoid crashes.
Brake Preparation
When quickly approaching a vehicle
ahead, Brake Preparation reduces
brake response time by having the
brake system prepared for driver
braking to occur more rapidly.
