The gearbox "winter mode" means that the
car moves off with a lower engine speed and
reduced engine power on the drive wheels.
Kick-down
When the accelerator pedal is pressed all the
way to the floor (beyond the position normally
regarded as full acceleration) a lower gear is
immediately engaged. This is known as kick-
down.
If the accelerator is released from the kick-
down position, the gearbox automatically
changes up.
Kick-down is used when maximum accelera-
tion is needed, such as for overtaking.
Safety function
To prevent overrevving the engine, the gear-
box control program has a protective down-
shift inhibitor which prevents the kick-down
function.
Geartronic does not permit downshifting/
kick-down which would result in an engine
speed high enough to damage the engine.
Nothing happens if the driver still tries to shift
down in this way at high engine speed – the
original gear remains engaged.
When kick-down is activated the car can
change one or more gears at a time depend-
ing on engine speed. The car changes up
when the engine reaches its maximum speed
in order to prevent damage to the engine.
