Safety Alert Seat will pulse five times.
Beeps for FPA are higher pitched than
for RPA.
Reversing Warning and Reverse
Automatic Braking (RAB)
Vehicles with Adaptive Cruise Control
(ACC) have the Reversing Warning
System and Reverse Automatic
Braking (RAB) system. When in
R (Reverse), Reversing Warning alerts
of rear objects at vehicle speeds
greater than 8 km/h (5 mph), and RAB
may automatically brake hard at
speeds between 1 32 km/h (0.5
20 mph).
The Reversing Warning System will
beep once from the rear when an
object is first detected, or pulse twice
on both sides of the Safety Alert Seat.
When the system detects a potential
crash, beeps will be heard from the
rear, or five pulses will be felt on both
sides of the Safety Alert Seat. There
may also be a brief, sharp application
of the brakes.
Warning
The Reversing Warning System only
operates at speeds greater than
8 km/h (5 mph). It does not detect
children, pedestrians, bicyclists,
animals, or objects below the
bumper or that are too close or too
far from the vehicle. In some
situations, such as at higher
reversing speeds, there may not be
enough time for the short, sharp
application of the vehicle brake
system to occur. To prevent injury,
death, or vehicle damage, even with
the Reversing Warning System,
always check the area around the
vehicle and check all mirrors before
reversing.
When the vehicle is in R (Reverse),
if the system detects the vehicle is
reversing too fast to avoid a crash
with a detected object behind your
vehicle in your path, it may
automatically brake hard to a stop to
help avoid or reduce the harm caused
by a reversing crash.
DRIVING AND OPERATING
Warning
RAB may not avoid many types of
reversing crashes. Do not wait for
the automatic braking to apply. This
system is not designed to replace
driver braking and only works in
R (Reverse) when an object is
detected directly behind the vehicle.
It may not brake or stop in time to
avoid a crash. It will not brake for
objects when the vehicle is moving
at very low speeds. It does not
detect children, pedestrians,
bicyclists, animals, or objects below
the bumper or that are too close or
too far from the vehicle. To prevent
injury, death, or vehicle damage,
even with RAB, always check the
area around the vehicle before and
while reversing.
Pressing the brake pedal after the
vehicle comes to a stop will release
RAB. If the brake pedal is not pressed
soon after the stop, the Electric
Parking Brake (EPB) may be set. When
it is safe, press the accelerator pedal
firmly at any time to override RAB.
