Magnetic Ride Control™

The vehicle may have Magnetic Ride Control that automatically adjusts the ride of the vehicle. The controller receives input from the system to determine the proper ride. If the controller detects a problem within the system, the Driver Information Center (DIC) displays a SERVICE SUSPENSION SYS message. See DIC Warnings and Messages for more information. If this message appears, have the vehicle serviced at your dealer/retailer.
