If the vehicle has a Navigation system, see "Head-Up Display (HUD)" in the Index of the navigation manual. The Manual Paddle Shift system will not allow either an up-shift or a down-shift if the vehicle speed is too fast or too slow, nor will it allow a start from 4 (Fourth) or higher gear. If up-shifting does not occur when needed, vehicle speed will be limited to protect the engine. The transmission will also automatically down-shift as the vehicle slows down and comes to a stop. When the transmission gear does not respond to a shift change, the DIC will show an X over the gear display. When a requested shift is denied due to the speed restrictions shown, the DIC will momentarily show an X over the gear display and a chime will sound. The vehicle speeds required for Manual Paddle Shift up-shifts depend on several vehicle inputs, which will vary the allowed up-shift speed by a few mph (km/h). • Up-shifts to 4 (Fourth) gear require approximately 22 mph (35 km/h). • Up-shifts to 5 (Fifth) gear require approximately 28 mph (45 km/h). • Up-shifts to 6 (Sixth) gear require approximately 41 mph (65 km/h). To prevent damage to the powertrain, Manual Paddle downshifts to a lower gear cannot be done above certain speeds. The maximum speed allowed for downshifting of gears 1 (First) through 4 (Fourth) are: Into 4 (Fourth) gear over 168 mph (270 km/h) Into 3 (Third) gear over 124 mph (200 km/h) Into 2 (Second) gear over 81 mph (130 km/h) Into 1 (First) gear over 45 mph (72 km/h). If the vehicle has a HUD, and the transmission gear does not respond to a shift change, a chime will sound and the HUD will momentarily show an X over the gear display. Manual Paddle Shift operation is available for use with Cruise Control. See Cruise Control on page 3-10 for more information. If the driver does not request an upshift as the engine speed approaches fuel shut off RPM, the engine speed will be limited to protect the engine. See Tachometer on page 3-35 for more information. 2-29
