Engine Stop

Engine Stop

An automatic engine stop is always performed when the power train or discharged battery require power. The rev counter then moves to the Ready position. The hybrid management system prevents the engine from stopping:
- if the engine or vehicle speed is too high (> 97 mph (156 km/h) or > 2,600 rpm)
- if the battery charge state (SOC) is too low
- if the battery charge state is too high and engine braking torque is required
- if the hood is open
- if the driver's seat belt is not fastened in P or N
- if the driver's door is open in P or N
- if faults have been detected/clutch is in emergency mode
- if engine diagnoses are running (catalytic converter, mixture adaptation, etc.)
- during the minimum operating time after initial start
- if the gradient is steeper than 7 %
- if cabin heating is required
- if the vehicle electrical system power or air-conditioning performance is too high
- if the engine/catalytic converter temperature is too low
- if the high-voltage battery is too warm or too cold less than 50° F. (10° C.) or > 108° F. 42° C.)
