There are several conditions that can cause this message to appear. TIGHTEN FUEL CAP If the vehicle's fuel cap is not tightened properly, this message may appear along with the check engine light on the instrument panel cluster. See Malfunction Indicator Lamp on page 3-46. Reinstall the fuel cap fully. See Filling the Tank on page 5-8. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn this light and message off. • One condition is overheating, which could occur if StabiliTrak activates continuously for an extended period of time. ® • The message will also be displayed if the brake system warning light is on. See Brake System Warning Light on page 3-42. • The message could be displayed if the stability system takes longer than usual to complete its diagnostic checks due to driving conditions. • If an engine or vehicle related problem has been detected and the vehicle needs service, the message will appear. See your GM dealer. TRACTION ACTIVE When the traction control system has detected that any of the vehicle's wheels are slipping, the traction control system will activate and this message will appear on the DIC. See StabiliTrak® System on page 4-9 for more information. • The message will also appear if the vehicle is shifted into 4LO. The message will turn off as soon as the conditions that caused the message to be displayed are no longer present. TRACTION SYS (System) LIMITED If the brake traction control system activates constantly or if the brakes have heated up due to high-speed braking, brake traction control will be disabled and the TRACTION SYS LIMITED message will be displayed. The system will return to normal operation after the brakes have cooled. See StabiliTrak® System on page 4-9 for more information. 3-65
