Summary

Engine coolant temperature amber warning is not enabled and not displayed on the instrument panel cluster. The engine coolant temperature amber warning gives the vehicle driver more warning and time to react to the engine getting hot. If the engine coolant temperature amber warning is not enabled the first warning for engine overheating is a red warning displayed on the instrument panel cluster, this then leads to engine power restriction to protect the vehicle. A Car Configuration File (CCF) update is required, the engine coolant temperature amber warning will then be displayed on the instrument panel cluster when required.
