FORD 2010 Flex v.1 - Manual (Page 276)

The message center display in the
instrument cluster will show the
current selected gear you are in.
In order to prevent the engine from
running at too low an RPM, which
may cause it to stall, the SST will
automatically make some downshifts even if it has determined that you
have not downshifted in time. It will still allow you to downshift at any
time as long as the SST determines that the engine will not be damaged
from over-revving.
Engine damage may occur if excessive engine revving is held
without shifting.
REVERSE SENSING SYSTEM
The Reverse Sensing System (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
WARNING: To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at “parking speeds”. Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.
WARNING: To help avoid personal injury, always use caution
when in R (Reverse) and when using the RSS.
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.
