To turn the system on or off, press the TRAC button on the far right end of the Driver Information Center (DIC) or the trip computer (if equipped). Steering Power Steering If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. Variable Effort Steering (Option) This steering system provides less steering effort for parking and when driving at speeds below 20 mph (32 km/h). Steering effort will increase at higher speeds for improved road feel. When you turn the system off, the Enhanced Traction System warning light will come on and stay on. If the Enhanced Traction System is limiting wheel spin when you press the button to turn the system off, the warning light will come on and the system will turn off right away. You can turn the system back on at any time by pressing the button again. The Enhanced Traction System warning light should go off. 4-12
