If there is a problem detected with StabiliTrak® Plus, this symbol along with the SERVICE STABILITY SYSTEM warning message will come on the DIC. See DIC Warnings and Messages on page 3-72. When this message is displayed, the system is not operational. Driving should be adjusted accordingly. To turn the StabiliTrak® system off (GXP only), press and hold the traction control button for more than five seconds. A message will appear on the DIC indicating that StabiliTrak® has been turned off. You can turn the system back on at any time by pressing the button again. If the vehicle is in cruise control when StabiliTrak® Plus activates, the cruise control will automatically disengage. When road conditions allow safe use of it, the cruise control can be used again. See Cruise Control on page 3-11 for more information. 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 If your vehicle has this steering system, the 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. Steering Tips It is important to take curves at a reasonable speed. A lot of the "driver lost control" accidents mentioned on the news happen on curves. Here is why: Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves. The traction of the tires against the road surface makes it possible for the vehicle to change its path when you turn the front wheels. If there is no traction, inertia will keep the vehicle going in the same direction. If you have ever tried to steer a vehicle on wet ice, you will understand this. 4-13
