How Long Can You Drive After the Mercedes-Benz Coolant Warning Appears?

[SanNora]

If the coolant warning is not caused by high temperature, you can still drive for a few kilometers. However, if the temperature is too high, you should not continue driving. Continuing to drive may cause the engine to overheat, leading to engine damage. In either case, a coolant warning poses a risk of engine damage. If the engine does not receive proper cooling for an extended period, internal damage may occur. High Temperature: If the coolant warning is due to the engine overheating, it is best to pull over, keep the engine idling, open the hood, and allow it to cool down until the temperature warning disappears. Low Coolant Level: If the warning is due to insufficient coolant and you do not have coolant available for immediate refill, you can add an appropriate amount of purified water—preferably soft water, such as distilled water. Do not use tap water or other hard water, and avoid adding too much, as this may alter the coolant's boiling point.
