Function of softkey : activate/deactivate ignition.
Pressing once will activate the ignition/stoppage magnet, and the symbol will be shown white on black. If pressed
again: Ignition to the engine will be turned off.
This function does not affect the starting of the engine. If the ignition is switched off (state after ES2 switched on),
the ignition/stoppage magnet output will be activated when the start button is pressed, and then the starter with a
delay of approx. 1-2 seconds. If the ignition has already been switched on with the key button, the engine can also
be started. The ignition output will stay activated.
When switching the engine off, the ignition/stoppage magnet output will always be switched off to stop the engine.
The softkey can be helpful for engine service technicians, who can sometimes only access the engine control
unit when the ignition is switched on.
If the ignition is switched on, the level of the AdBlue tank will be displayed.
This can prevent the AdBlue tank from overflowing when AdBlue is being topped up.
The fill level of the AdBlue tank should not go below 22%. Top up in good time.
If this is not done, there may be a reduction in power by the engine control unit.
Only switch off the battery main switch about 2 mins after the ES2 has been turned off.
During this time, the AdBlue lines are emptied in order to prevent them from becoming
blocked up.
