Driving D (Drive) with Overdrive Cancel and Grade Assist Initially, moving the lever to (M) activates two features at the same time: Overdrive Cancel and Grade Assist. • The grade assist lamp in the instrument cluster is illuminated. 1. • • 2. • Overdrive Cancel Overdrive is deactivated. The transmission operates in gears one through five. Grade Assist Improves driving experience in hilly terrain or mountainous areas by providing additional grade (engine) braking and extends lower gear operation on uphill climbs. • 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. 232
