Front Automatic Braking
(FAB) System
If the vehicle has Adaptive Cruise
Control (ACC), it also has FAB,
which 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 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 0 283.
The system works when driving in a
forward gear above 4 km/h (2 mph).
It can detect vehicles up to
approximately 60 m (197 ft).
{
Warning
FAB is an emergency crash
preparation feature and is not
designed to avoid crashes. Do
not rely on FAB to brake the
vehicle. FAB will not brake
outside of its operating speed
range and only responds to
detected vehicles.
FAB 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.
(Continued)
Warning (Continued)
.
Detect a vehicle ahead if it
is partially blocked by
pedestrians or other objects.
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.
FAB may slow the vehicle to a
complete stop to try to avoid a
potential crash.
{
Warning
FAB 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 FAB, firmly
press the accelerator pedal, if it is
safe to do so.
