Note
● You can control whether the engine should
switch off or not by reducing or increasing the
brake force applied. While the vehicle re-
mains stopped, the engine will not stop if the
brake pedal is slightly pressed, in traffic jams
with frequent stopping and starting for exam-
ple. As soon as strong pressure is applied to
the brake pedal, the engine will stop.
● In vehicles with manual gearbox, during
the stopping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
If the engine "stalls" in vehicles with man-
●
ual gearbox, it can be directly started up
again by immediately pressing the clutch
pedal.
