When the System Does Not Seem to Work
Properly
If the vehicle does not reverse into the
expected parking space, the system could be
maneuvering the vehicle into a previously
detected space.
Reverse Automatic Braking (RAB)
Backing Warning and RAB
Vehicles with Adaptive Cruise Control (ACC)
have the Backing Warning System and RAB
system. When in R (Reverse), Backing
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 Backing 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 sound from the
rear, or five pulses will occur on both sides
of the Safety Alert Seat. There may also be
a brief, sharp application of the brakes.
{
Warning
The Backing 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 backing
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 Backing Warning System, always
check the area around the vehicle and
check all mirrors before backing.
When the vehicle is in R (Reverse), if the
system detects the vehicle is backing 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 crash.
