ASC (Adoptive Shift Control)
ASC automatically shifts or hold at the 2nd, 3rd or 4th gear on certain roads (up/down slope and curve) and driving condition.
When Driving On an Up/Down Slope
- ASC judges up/down slope according to engine torque data transmitted from the ECM and vehicle speed. Holding gear at the 3rd or 4th on an up-slope prevents shift hunting and controls the vehicle to gain optimum driving force. On a down-slope, automatic shift-down to the 3rd or 4th gear controls to gain optimum engine brake.
When Driving On a Curve
- TCM receives the lateral G sensor signal from the ABS actuator control unit. It locks the gear to the 3rd or 4th position in moderate cornering or to the 2nd position in sharp cornering based on this signal. This prevents any upshift and kickdown during cornering, maintaining smooth vehicle travel.
DS Mode
- Changes to the shift schedule that mainly utilizes the high engine speed zone when ASC is active.
- DS mode can be switched according to the following method.
- When the selector lever is in the "D" position, shifting the selector lever to manual shift gate enables switching to DS mode.
- When in DS mode, shifting the selector lever to the main gate enables to cancel DS mode.
