Forward Automatic; Braking (Fab) - Cadillac XT5 2017 Owner's Manual

228 DRIVING AND OPERATING

FORWARD AUTOMATIC

BRAKING (FAB)

If the vehicle has Forward Collision
Alert (FCA), 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 forward 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 0 225.
The system works when driving in a
forward gear between 8 km/h (5 mph)
and 80 km/h (50 mph), or on vehicles
with Adaptive Cruise Control (ACC),
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.
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. If this happens, FAB
may engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop.
Release the EPB or firmly press the
accelerator pedal.
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.
Intelligent Brake Assist (IBA)
IBA may activate when the brake pedal
is applied quickly by providing a boost
to braking based on the speed of
approach and distance to a vehicle
ahead.
Minor brake pedal pulsations or pedal
movement during this time is normal
and the brake pedal should continue
