Lincoln Aviator: Reverse Braking Assist
What Is Reverse Braking Assist

The system is designed to reduce impact
damage or avoid a collision completely by
using the sensors on the rear of your vehicle.
The system functions when in reverse (R)
and traveling at a speed of 1–7 mph
(1.5–12 km/h).
If the system detects an obstacle behind your
vehicle, it provides a warning through the
rear parking aid or cross traffic alert system.
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake.
WARNING: You must remain in your
vehicle when the system turns on...
WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention...
Other information:
WARNING:
Always refer to Material Safety Data Sheet (MSDS) when handling
chemicals and wear protective equipment as directed. Examples may
include but are not limited to respirators and chemically resistant
gloves. Failure to follow these instructions may result in serious
personal injury...
