When using the Manual Paddle Shift feature while in S (Sport Mode), the current gear will be displayed in the Driver Information (DIC), or the Head-Up Display (HUD), if the vehicle has either of these features. 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. 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. 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 4-7 for more information. 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). 3-29
