Danger | Risk of death when working on component parts and systems with U >= 30 V alternating voltage (AC) or U >= 60 V direct voltage (DC) | Do not touch damaged or defective live component parts and lines or non-insulated electrical connections and lines. | |
Warning | Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. Risk of poisoning from swallowing coolant. | Do not open cooling system unless coolant temperature is below 90 °C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers. | |

| Check | ||
1 | Check all coolant lines and coolant hoses for leak tightness and condition. | ||
2 | Check coolant expansion reservoir for leak tightness and condition. | ||
Replace coolant | |||
3 | Drain coolant of auxiliary circuit then fill again. | ||
| |||
If the coolant is too strongly dirt-laden, | |||
| |||
clean auxiliary circuit. | |||
After obtaining special order. | |||
4 | Confirm replacement of coolant in maintenance booklet or in Digital Service Booklet (DSB). |
