A vehicle steering mode selection control system includes an operator controlled push-to-turn switch steering mode select device, and a control circuit operatively connected to the mode select device, to steering mode actuators, to steering mode indicators and to wheel alignment indicators. The control circuit includes a timer which is actuated for a certain time period in response to pushing of the push-to-turn switch. A lamp control module is connected to the timer and permits illumination of the wheel alignment indicator lamps only during this time period. A relay is connected between the push-to-turn switch and the timer to prevent the lamp control module from responding during the time period to further pushing of the steering mode select device.
