This is to prevent overheating of the brake system and is a normal condition. The system will remain disabled for about four minutes until the brakes have cooled. The system will automatically reactivate and turn off the TCS Indicator light. If your vehicle becomes stuck in mud, ice, or snow, turn the Traction Control System Off before attempting to "rock" the vehicle free. 5 1 - U.S. DOT Safety Standards Code (TIN) 2 - Size Designation 3 - Service Description 4 - Maximum Load 5 - Maximum Pressure 6 - Treadwear, Traction and Temperature Grades
