Automatic Collision
Preparation (ACP) System
When driving in a forward gear
above 4 km/h (2.5 mph), ACP may
help reduce crash damage by
applying the brakes. It has a
detection range of approximately
60 m (197 ft). This front automatic
braking can only occur if a vehicle is
detected. This is shown by the FCA
vehicle ahead indicator being lit.
See Forward Collision Alert (FCA)
System on page 9-54.

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.
(Continued)
Warning (Continued)
.
Detect a vehicle ahead on
winding or hilly roads.
.
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.
Automatic Braking
If ACP detects it is about to crash
with the vehicle you are following
that is moving or has come to a
stop, and the brakes have not been
applied, it may automatically brake
hard. This can help to reduce crash
damage and it may even help to
avoid some very low speed crashes.
Automatic Braking may slow the
vehicle to a complete stop to try to
avoid a potential crash. If this
happens, Automatic Braking may
engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop.
To release the EPB, press the EPB
button. A firm press of the
accelerator pedal will also release
Automatic Braking and the EPB.
{
Warning
Automatic Braking may
automatically brake the vehicle
suddenly in situations where it is
unexpected and undesired.
