When stopping, the engine will not switch off for the following reasons,
among others. ▶ The engine temperature for the proper function of the system has not yet
been reached.
▶ The charge state of the vehicle battery is too low.
▶ The current consumption is too high.
▶ High air conditioning or heating output (high blower speed, big difference be-
tween the desired and actual interior temperature).
If the engine is shut down automatically and the system detects that the en- gine is required, such as when the brake pedal is pressed repeatedly, then the
system automatically starts the engine.
More information about the current system status can be displayed in infotain-
ment screen, in the
