[spacer]
Display of the additional reserve if the coolant temperature is taken into
account. This display is relevant if the coolant temperature has been set to a
value below the maximum permissible coolant temperature or, in other words, if
the thermal model has been shifted downwards.
If, on the other hand, the coolant temperature and the maximum permissible
coolant temperature have been set to the same value, then the coolant
temperature is not taken into account and the characteristic is a function of the
current only. The additional reserve amounts to 0 in this case.
