To Resume Speed To resume a previously set speed, push the RESUME ACCEL lever up and release. Resume can be used at any speed above 20 mph (32 km/h) for 3.7L, 4.7L, and 5.7L engines, and 14 mph (23 km/h) for 3.0L diesel engines. To Vary The Speed Setting When the Electronic Speed Control is on, speed can be increased by pushing up and holding RESUME ACCEL. Release the lever when the desired speed is reached, and the new speed will be set. Tapping RESUME ACCEL once will result in a 1 mph (2 km/h) (3.7L, 4.7L, 5.7L, and 3.0L diesel engines) speed increase. Each time the lever is tapped, speed increases so that tapping the lever three times will increase speed by 3 mph (5 km/h) (3.7L, 4.7L, 5.7L, and 3.0L diesel engines). To decrease speed while Electronic Speed Control is on, push down and hold SET DECEL. Release the lever when the desired speed is reached, and the new speed will be set. Tapping the SET DECEL lever once will result in a 1 mph (2 km/h) speed decrease. Each time the lever is tapped, speed decreases. NOTE: The Electronic Speed Control system has been designed to shut down if multiple speed control switch functions are operated simultaneously in order to ensure proper operation. If this occurs, the system can be reactivated by pushing the Electronic Speed Control switch ON/OFF button and resetting the desired vehicle SET speed.
