Automatic Emergency

Braking (AEB)

If equipped, the AEB system may help avoid
or reduce the harm caused by front-end
crashes. AEB also includes Intelligent Brake
Assist (IBA). 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 automatic
emergency 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 0 263.
The system works when driving in a forward
gear between 8 km/h (5 mph) and 80 km/h
(50 mph). It can detect vehicles up to
approximately 60 m (197 ft).
Warning
AEB is an emergency crash preparation
feature and is not designed to avoid
crashes. Do not rely on AEB to brake the
vehicle. AEB will not brake outside of its
operating speed range and only responds
to detected vehicles.
AEB may not:
Detect a vehicle ahead on winding or
hilly roads.
Detect all vehicles, especially vehicles
with a trailer, tractors, muddy
vehicles, etc.
Detect a vehicle when weather limits
visibility, such as in fog, rain, or snow.
Detect a vehicle ahead if it is partially
blocked by pedestrians or other
objects.
Driving and Operating
Warning (Continued)
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.
AEB may slow the vehicle to a complete
stop to try to avoid a potential crash. If this
happens, AEB may engage the Electric
Parking Brake (EPB) to hold the vehicle at a
stop. Release the EPB or firmly press the
accelerator pedal.
AEB may automatically brake the vehicle
suddenly in situations where it is
unexpected and undesired. It could
respond to a turning vehicle ahead,
guardrails, signs, and other non-moving
objects. To override AEB, firmly press the
accelerator pedal, if it is safe to do so.
Intelligent Brake Assist (IBA)
IBA may activate when the brake pedal is
(Continued)
applied quickly by providing a boost to
braking based on the speed of approach and
distance to a vehicle ahead.
