Driving • Provides additional engine braking through the automatic transmission shift strategy which reacts to vehicle inputs (vehicle acceleration, accelerator pedal, brake pedal and vehicle speed). • Allows the transmission to select gears that will provide the desired engine braking based on the vehicle inputs mentioned above. This will increase engine RPM during engine braking. Overdrive Cancel with Grade Assist is designed to provide optimal gear selection in hilly terrain or mountainous areas. It is recommended that you return to O/D (overdrive mode) on flat terrain to provide the best fuel economy and transmission function. To return to O/D (overdrive mode), press the transmission control switch again. • The overdrive cancel and grade assist lamp in the instrument cluster will not be illuminated. • The transmission will operate in gears one through six. O/D (overdrive mode) is automatically returned each time the key is turned off. L (Low) • Provides maximum engine braking. • Will downshift to the lowest available gear for the current vehicle speed; allows for first gear when vehicle reaches slower speeds. 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. 273 2009 Flex (471) Owners Guide, 2nd Printing USA (fus)
