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. If this happens, FAB
may engage the Electric Parking
Brake (EPB) to hold the vehicle at a
stop. Release 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

Vehicle Personalization 0 128.

could cause you to lose control of
the vehicle and crash. Turn the
system to Off when towing a
trailer.
