THROTTLE VALVE POSITION(V) range V to 4.680V) Indicates the throttle valve position sensor voltage on a P transmission. When accelerating from idling to WOT, the voltage figure increases constantly. With the vehicle stationary, idling should be min. 0.165, max V, and WOT should read minimum 3.5 to maximum 4.680V. NOTE: i Diesel engine voltage may differ slightly.

146 Data Parameters Transmission Parameters TIPTRONIC Indicates the selected gear range of a Tiptronic transmission. Tiptronic transmissions have an additional selector gate on the right of the transmission shifter selector gate or steering wheel paddles. Tiptronic makes it possible to manually shift up a gear by moving the selector lever or steering wheel paddles to plus (+) or manually shift down a gear by moving the selector lever or steering wheel paddles to negative (-). This mode is for drivers who prefer manual gear shifting. The transmission will upshift automatically to prevent inadvertent over-revving of the engine. Also, the driver cannot downshift to a lower gear if the engine RPM would exceed red-line by downshifting. In addition, the transmission will downshift to first automatically when the vehicle comes to a stop, even if the driver does not remember to downshift. This transmission is designed to handle high torque output. The left-hand gate is for electronically controlled automatic shifting with adaptive control. This is a function of various sensors and is transparent to the driver. Shift points are automatically regulated to provide three distinct operating characteristics: • Comfort driving for maximum fuel economy (shift points are kept low).
