224 Transmission D (Drive) with Grade Assist Press the transmission control switch on the side of the gearshift lever to activate grade assist and cancel overdrive. P R N D 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. Press the transmission control switch again to return to normal D (Drive) position (with O/D). • The grade assist lamp in the instrument cluster will not be illuminated. • The transmission will operate in gears one through six. 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. • Is not intended for use under extended or normal driving conditions and results in lower fuel economy. 2013 Explorer (exp) Owners Guide gf, 4th Printing, November 2012 USA (fus) L
