Driving 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. 276 2010 Flex (471) Owners Guide, 2nd Printing USA (fus)
