Excessive coolant temperature triggers a warning in the multifunction display. The engine should not be operated with a coolant temperature above 248‡ (120†), i.e. in the red zone of the coolant temperature gauge. Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty. Tachometer X To brighten illumination: Turn dimmer : clockwise.
