A vehicle control system uses a touchscreen display to displaying a graphical HMI and detect a contact point where touched by a user's finger. A haptic texture system has an electrode disposed across the touchscreen display and a signal generator generating an oscillating signal to produce a potential difference between the finger and the electrode resulting in a corresponding perceived texture as the finger slides over the touchscreen. A control circuit is configured to set at least a frequency or amplitude of the oscillating signal to vary the perceived texture according to first and second modes while navigating the graphical HMI. The first mode uses a localized texture mapping defined by respective feature icon selection regions on the touchscreen display. The second mode uses a status texture mapping relating the perceived texture to each potential adjustment setting available for a feature icon that has been selected using the first mode.
