Cruise Control These controls are located on the end of the multifunction lever. R (On): Move to this position to turn on the system. + (Resume/Accelerate): Move to this position to make the vehicle resume a previously set speed or to accelerate when cruise is already active. T (Set/Decrease): Press this button to set the speed or to decrease the speed when cruise is already active. With cruise control, a speed of about 25 mph (40 km/h) or more can be maintained without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). 9 (Off): Move to this position to turn the system off. 193
