Can the Mercedes-Benz CLA Continue Driving When the Coolant Warning Light Comes On?

[DiBrandon]

If the Mercedes-Benz CLA displays a coolant warning, you should not continue driving and must contact a maintenance technician for inspection. Continuing to drive may cause the engine temperature to rise excessively, leading to engine damage. Overheating Coolant: If the coolant warning is triggered due to high engine temperature, it is best to pull over safely. Do not turn off the engine—let it idle, open the hood, and allow it to cool until the temperature warning disappears. Insufficient Coolant: If the coolant warning is due to low coolant levels and you do not have coolant available for immediate replenishment, you can add an appropriate amount of purified water—preferably soft water (such as distilled water). Note that hard water, like tap water, should not be used, and the added amount should not be excessive, as it may alter the coolant's boiling point.
