Transmission Control Switch (TCS) Button

WARNING: This page is about a different car, the 2013 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.

The TCS button is located on the selector lever.

Grade Assist improves vehicle handling in hilly terrain or mountainous areas by providing additional engine braking and extends lower gear operation on uphill climbs. Additional engine braking is provided through the automatic transaxle shift strategy which reacts to vehicle inputs including vehicle acceleration, accelerator pedal, brake pedal and vehicle speed. The transaxle will select gears that will provide the desired engine braking, based on the vehicle inputs, the engine rpm during engine braking will increase. It is recommended to return to DRIVE mode on flat terrain to provide the best fuel economy and transaxle function. The transaxle returns to Overdrive (O/D) and grade assist is cancelled when the TCS is pressed again.
