The system provides the following performance benefits: ... 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 through increased steering effort and suspension tuning. The setting can be changed at any time. Based on road conditions, steering wheel angle, and 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. Reduced Impact Harshness Improved Road Isolation Improved High-Speed Stability Improved Handling Response Better Control of Body Ride Motions Limited-Slip Differential Vehicles with a limited-slip differential can give more traction on snow, mud, ice, sand, or gravel. It works like a standard differential most of the time, but when traction is low, this feature allows the drive wheel with the most traction to move the vehicle. . To switch from TOUR to SPORT mode, move the shift lever to the M/S (Manual/Sport) position.
