9-30 Driving and Operating When the transmission gear does not respond to a shift change, the DIC will show an X over the gear display. The driver may then exit Manual Paddle Shift mode by holding either upshift control for more than one second. The system will return to automatic shifting after 10 seconds of cruising at a steady speed and no manual shifts, or when the vehicle comes to a stop. While the Manual Paddle Shift gear selection system is active, the transmission will automatically downshift through the gears as the vehicle slows. The transmission will select 2 (Second) gear as the vehicle stops. From a stop, the vehicle will start from and hold 2 (Second) gear unless the driver manually paddle shifts into a different gear or selects D (Drive). The driver can select 1 (First) gear for maximum acceleration from a stop. 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 Head-Up Display (HUD), see Head-Up Display (HUD) on page 5‑31. 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 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 9‑45 Cruise Control for more information.
