This mode provides a comfortable, smooth ride. Press the button again and the system returns to the Standard mode.

Drive Mode Control

Drive Mode Control (DMC) analyzes the driving style and the active state of the vehicle and automatically changes the settings within the selected driving mode. When there is a more noticeable change in driving style or conditions, the driving mode is changed to Sport until the previous driving style returns.

If Standard mode is selected and sport driving is detected, several settings of the Standard mode change to sport settings. If sport driving increases, DMC changes to Sport mode.

If Tour mode is selected and sudden braking or cornering is necessary, DMC changes the suspension settings to Sport mode to increase vehicle stability.

When the driving characteristic or the active state of the vehicle returns to the previous style, DMC changes the settings to the preselected driving mode.
