FORD 2012 Focus v.4 - Manual (Page 283)

WARNING: This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller
objects, particularly those close to the ground.
WARNING: Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the
normal detection zone of the forward and reverse sensing system may
create false beeps.
The system will sound a tone to warn the driver of obstacles near either
bumper in the following manner:
• Objects detected by the front sensors will be indicated by a high
pitched tone from the front radio speakers.
• Objects detected by the rear sensors will be indicated by a lower
pitched tone from the rear radio speakers.
• The sensing system will report the obstacle which is closest to the
front or rear of the vehicle. For example, if an obstacle is 24 inches
(60 cm) from the front of the vehicle and, at the same time, an
obstacle is only 16 inches (40 cm) from the rear of the vehicle, the
lower pitched tone will sound.
• You will hear an alternating tone from the front and rear if there are
objects both at the front bumper and rear bumper that are closer than
10 inches (25 cm).
The reverse sensing portion of the system will assist the driver in
detecting certain objects while:
• the vehicle is in R (Reverse) and moving toward a stationary object at
a speed of 3 mph (5 km/h) or less.
• the vehicle is in R (Reverse) but not moving, and a moving object is
approaching the front or rear of the vehicle at a speed of 3 mph
(5 km/h) or less.
• the vehicle is in R (Reverse) and moving at a speed of less than
3 mph (5 km/h) and a moving object is approaching the rear of the
vehicle at a speed of less than 3 mph (5 km/h).
The system is automatically enabled when the gearshift lever is placed in
D (Drive) or R (Reverse) and the ignition is on. A control in the message
center allows the driver to disable the reverse system. Refer to Message
center in the Instrument Cluster chapter for more information.
