Key adaptive tow/haul features: • The system will remain in the same mode, even after a key cycle. • Is only available in normal drive modes (Normal 2H and Normal 4A). The adaptive tow/haul feature improves transmission operation when towing a trailer or a heavy load. All transmission gear ranges are available when using adaptive tow/haul. For information on towing. See Towing (page 298). SelectShift™ Automatic Transmission Your vehicle is equipped with a SelectShift Automatic transmission. The SelectShift Automatic transmission gives you the ability to change gears up or down (without a clutch) as desired.

In order to prevent the engine from running at too low an RPM, which may cause it to stall, SelectShift still automatically makes some downshifts if it has determined that you have not downshifted in time. Although SelectShift makes some downshifts for you, it still allows you to downshift at any time as long as the SelectShift determines that damage will not be caused to the engine from over-revving. Note: Engine damage may occur if you maintain excessive engine revving without shifting. SelectShift does not automatically upshift, even if the engine is approaching the RPM limit. It must be shifted manually by pressing the + paddle. Pull the + paddle on the steering wheel to activate SelectShift. • Pull the right paddle (+) to upshift. • Pull the left paddle (–) to downshift.
