Driving M (Manual) with Grade Assist Initially, moving the lever to M (Manual) activates grade assist and cancels Overdrive. Grade Assist: • Provides additional grade (engine) braking and extends lower gear operation on uphill climbs for hilly terrain or mountainous areas. • 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. • The grade assist lamp in the instrument cluster is illuminated. Grade assist is designed to aid the driver with optimal gear selection in hilly terrain or mountainous areas but is not intended for normal operation. 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 normal D (Drive) position (with O/D), move the shift lever back from M (Manual) to D (Drive). • The grade assist lamp in the instrument cluster will not be illuminated. • The transmission will operate in gears one through six. 274 2010 Flex (471) Owners Guide, 2nd Printing USA (fus)
