Warming-Up Program

The warming-up program is activated after each engine start with the engine temperature lower than approx.60 °C. In the warming-up program, the automatic transmission remains in the performance-orientated map XE or XS up to a certain temperature. Gearshift are only executed at higher speeds. This enables the engine and the catalytic converter to reach their operating temperatures more quickly.

Up to a transmission oil temperature of approximately 35 °C, the converter lockup clutch is neither controlled nor closed.
