SERVICE TRACTION If your vehicle has the Enhanced Traction System (ETS) or Traction Control System (TCS), this message displays and a chime sounds when the system is not functioning properly. The ETS light or the ESC/TCS light also appears on the instrument panel cluster. This light stays on solid as long as the detected problem remains present. When this message displays, the system is not working. Adjust your driving accordingly. See Enhanced Traction System (ETS) on page 4-9 or Traction Control System (TCS) on page 4-6 and Enhanced Traction System Warning Light on page 3-32 or Electronic Stability Control (ESC)/Traction Control System (TCS) Indicator/Warning Light on page 3-33 for more information. Have the system serviced by your dealer/retailer as soon as possible. SVC (Service) TIRE MONITOR This message displays if a part on the Tire Pressure Monitor System (TPMS) is not working properly. The tire pressure light also flashes and then remains on during the same ignition cycle. See Tire Pressure Light on page 3-34. Several conditions may cause this message to appear. See Tire Pressure Monitor Operation on page 5-59 for more information. If the warning comes on and stays on, there may be a problem with the TPMS. See your dealer/retailer. TIRE LEARN ON On vehicles without the Remote Keyless Entry (RKE) system, this message displays when the Tire Pressure Monitor System (TPMS) is re-learning the tire positions on your vehicle. 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 5-63, Tire Pressure Monitor System on page 5-57, and Inflation - Tire Pressure on page 5-56 for more information. 3-47
