FORD 2014 Explorer v.2 - Manual (Page 265)

CTA warns the driver of vehicles approaching from the sides when the
transmission is in R (Reverse).
Note: BLIS® is not designed to prevent contact with other vehicles or
objects; or to detect parked vehicles, people, animals or infrastructure
(fences, guardrails, trees, etc.). It is designed to alert the driver to
vehicles in the blind zones.
Note: When a vehicle passes quickly through the blind zone (typically
fewer than two seconds), the system does not trigger.
Using the Systems
BLIS® turns on when the engine is started and the vehicle is driven
forward above 3 mph (5 km/h); it remains on while the transmission is in
D (Drive) and N (Neutral). If shifted out of D (Drive) or N (Neutral),
the system enters CTA mode. Once shifted back into D (Drive), BLIS®
turns back on when the vehicle is driven above 3 mph (5 km/h).
Note: BLIS® does not function in R (Reverse) or P (Park) or provide
any additional warning when a turn signal is on.
CTA detects approaching vehicles from up to 45 feet (14 meters) away
though coverage decreases when the sensors are blocked. Reversing
slowly helps increase the coverage area and effectiveness.
WARNING: To help avoid personal injury, NEVER use the CTA
system as a replacement for using the interior and exterior
mirrors and looking over your shoulder before backing out of a parking
space. CTA is not a replacement for careful driving and only an assist.
