2009 Dodge Challenger Owner's Manual - Page 289

STARTING AND OPERATING 287 NOTE: To improve the vehicle's traction when driving with snow chains, or when starting off in deep snow, sand, or gravel, it may be desirable to switch to the "Partial Off" mode by momentarily pressing the "ESP OFF" switch. Once the situation requiring "Partial Off" mode is overcome, turn the ESP ON again by momentarily pressing the "ESP OFF" switch. This may be done while the vehicle is in motion. Synchronizing ESP The Malfunction Indicator Light for the ESP is combined with BAS indicator. If the power supply is interrupted (battery disconnected or discharged), the "ESP/BAS Malfunction Indicator Light" may illuminate with the engine running. If this should occur, turn the steering wheel completely to the left and then to the right. The "ESP/BAS Malfunction Indicator Light" should go out. However, if the light remains on, have the ESP and BAS checked at your authorized dealer as soon as possible. ESP/BAS Malfunction Indicator Light and ESP/TCS Indicator Light The Malfunction Indicator Light for the ESP is combined with the BAS indicator. The "ESP/ BAS Malfunction Indicator Light" and the "ESP/TCS Indicator Light" in the instrument cluster both come on when the ignition switch is turned to the ON position. They should go out with the engine running. The system will turn the "ESP/BAS Malfunction Indicator Light" on continuously while the engine is running if it detects a malfunction in either the ESP or the BAS or both. If the light remains on after several ignition cycles and you have driven the vehicle several miles (kilometers) at speeds greater than 30 mph (48 km/h), and the ESP is synchronized (refer to Synchronizing ESP), see your authorized dealer as soon as possible to have the problem diagnosed and corrected. 5
