Reverse Automatic Braking (Rab) - Cadillac XT4 2023 Owner's Manual

220 Driving and Operating
The parking brake is applied.
Driver unbuckles the seat belt and opens
the door.
System Limitations
Automatic Parking Assist has certain
limitations. The system cannot:
Continue to operate if the manoeuvre
speed exceeds 5 km/h (3 mph).
Detect whether a parking space is legal or
restricted.
Detect pavement markings or lines.
Park the vehicle closely lined up with the
vehicle next to it, particularly if the spot
is approached at an angle or if the
parking space is angled.
Park exactly centred in a very large spot.
Always detect short curbs.
Operate while towing any trailer.
Function the vehicle is raised or lowered
by air suspension,if equipped.
When the System Does Not Seem to Work
Properly
If the vehicle does not reverse into the
expected parking space, the system could be
manoeuvring the vehicle into a previously
detected space.

Reverse Automatic Braking (RAB)

Reversing Warning and Reverse
Automatic Braking (RAB)
If equipped, vehicles with Adaptive Cruise
Control (ACC) have the Reverse 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.
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
