STARTING AND OPERATING 337 ESP/BAS Warning Lamp and ESP/TCS Indicator Light The malfunction indicator for the ESP is combined with the BAS indicator. The yellow "ESP/BAS Warning Lamp" and the yellow "ESP/TCS Indicator Light" in the instrument cluster both come on when the ignition switch is turned to the ON position. They should both go out with the engine running. If the "ESP/BAS Warning Lamp" comes on continuously with the engine running, a malfunction has been detected in either the ESP or BAS system, or both. If this light remains on after several ignition cycles, and the vehicle has been driven several miles/kilometers at speeds greater than 30 mph (48 km/h), see your authorized dealer as soon as possible to have the problem diagnosed and corrected. NOTE: • The "ESP Indicator Light" and the "ESP/BAS Warning Lamp" come on momentarily each time the ignition switch is turned ON. • Each time the ignition is turned ON, the ESP System will be ON even if it was turned off previously. • The ESP Control System will make buzzing or clicking sounds when it is active. This is normal. The sounds will stop when ESP becomes inactive following the maneuver that caused the ESP activation. TSC (Trailer Sway Control) The TSC system uses sensors in the vehicle to recognize an excessively swaying trailer and will take the appropriate actions to attempt to stop the sway. The system may reduce engine power and apply the brake of the appropriate wheel(s) to counteract the sway of the trailer. TSC will become active automatically once an excessively swaying trailer is recognized. No driver action is required. Note that TSC cannot stop all trailers from swaying. Always use caution when towing a trailer and follow the trailer tongue weight recommendations. Refer to "Trailer Towing" in Section 5 of this manual for more 5
