Blocking AUTOSTOP Cause, Coolant Temperature

The following causes block autostop:

• Depending on the engine temperature, after the engine is started, it needs to run for a while before autostop is permitted. The amount of time it needs to run after starting depends on the engine temperature. E.g., at +40 °C the engine must run for longer than 2 seconds.
• Engine coolant temperature is below +20 °C.
