Drive with Grade Assist - Transmission Control Switch (TCS)
Drive with grade assist is activated when the Transmission Control Switch (TCS) is pressed. The Transmission Control Switch (TCS) is located on the selector lever knob. When the Transmission Control Switch (TCS) is pressed, the 6th gear or Overdrive (O/D) upshift is prevented or the transaxle shifts down to 5th gear. The Transmission Control Switch (TCS) is meant to be used when driving conditions cause excessive shifting from 6th to other gears such as hilly terrain, mountainous areas or when engine braking is required.
Grade Assist
- Improves vehicle handling in hilly terrain or mountainous areas by providing engine braking and extending lower gear operation on uphill climbs.
- Additional engine braking is provided through the automatic transaxle shift strategy which reacts to vehicle inputs (vehicle acceleration, accelerator pedal, brake pedal and vehicle speed).
- The transaxle will select gears that will provide the engine braking desired, based on the vehicle inputs, this will increase engine rpm during engine braking.
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) when the Transmission Control Switch (TCS) is pressed again or anytime the key is turned OFF.
