Magnetic Ride Control
With this feature on the CTS-V, the Magnetic Ride Control system adjusts the ride of the vehicle to Tour or Sport modes. Magnetic Ride Control monitors the suspension system to determine the proper system response.
TOUR: Use for normal city and highway driving. This setting provides a smooth, soft ride.
SPORT: Use where road conditions or personal preference demand more control. This setting provides more “feel,” or response to road conditions.
The setting can be changed at any time. Based on road conditions, steering wheel angle, and the vehicle speed, the system automatically adjusts to provide the best handling while providing a smooth ride. The Tour and Sport modes will feel similar on a smooth road. Select a new setting whenever driving conditions change.
The Driver Information Center (DIC) briefly displays SUSPENSION MODE TOUR or SUSPENSION MODE SPORT on vehicle startup or when a new mode is selected.

Press and release this button, located in the center of the instrument panel, to change modes.
