Driver Shift Control (DSC) Your vehicle has a Driver Shift Control (DSC). The DSC controls the vehicle's transmission and vehicle speed while driving down hill or towing a trailer by allowing you to select a desired range of gears. To use this feature: 1. Move the shift lever to the MANUAL MODE (M). This will force a downshift from the current gear, for gears 3 through 6. 2. Press the (+) plus or (−) minus button on the left side of the steering wheel, to select the desired range of gears for your current driving conditions. When in the MANUAL MODE (M) a number will display next to the M, indicating the maximum available gear. The DIC display will show the message MANUAL SHIFT on the first line and the maximum available gear will be displayed on the second line. See Driver Information Center (DIC) on page 3-49 and DIC Operation and Displays (Using DIC Buttons) on page 3-49 or DIC Operation and Displays (Using Trip Odometer Reset Stem) on page 3-54 for more information. The number displayed in the DIC is the highest gear available. The transmission will be limited to the gear selected and lower gears. Shifting will occur normally while driving, however the cluster will continue to display the maximum available gear. Higher gears will not be available unless the selection is changed to include higher gears using the (+) plus button. Grade Braking is not available when the Driver Shift Control is active. See Tow/Haul Mode on page 2-36 and Towing a Trailer on page 4-55 for more information. While using the DSC, cruise control and the tow/haul mode can be used. 2-35
