There are several conditions that can cause this message to appear. • 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 246. • 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 dealer. • 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. TIGHTEN GAS CAP If the vehicle's fuel cap is not tightened properly, this message may display along with the check engine light on the instrument panel cluster. See Malfunction Indicator Lamp on page 250. Reinstall the fuel cap fully. See Filling the Tank on page 448. 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. TIRE LEARNING ACTIVE If your vehicle has a Tire Pressure Monitor (TPM) system, this message will display when the system is re-learning the tire positions on your vehicle. See DIC Operation and Displays (With DIC Buttons) on page 258 or DIC Operation and Displays (Without DIC Buttons) on page 265 for more information. The tire positions must be re-learned after rotating the tires or after replacing a tire or sensor. See Tire Inspection and Rotation on page 515, Tire Pressure Monitor System on page 510, and Inflation - Tire Pressure on page 509 for more information. 277
