Warm-Up Program




Warm-up Program

The warm-up program is selected after every engine start when the engine temperature is below 60 °C (approx.). The upshifts occur at a higher engine rpm allowing the engine and catalytic converters to reach operating temperature faster. The warm-up program is not in effect when the engine temperature is above 60 °C or after 120 seconds of operation.
