Can You Continue Driving When Mercedes Prompts to Refill Coolant?

Coolant warning indicates insufficient coolant in the car or possibly an overheated radiator. It is advisable not to continue driving under such circumstances. Prolonged driving may lead to increasingly high engine temperatures, potentially causing engine damage. Below are the key functions of coolant: 1. Anti-corrosion: Coolant does not corrode the engine cooling system and also provides anti-corrosion and rust removal functions. 2. Prevention of boiling: Water boils at 100°C, whereas high-quality coolant typically has a boiling point above 110°C, preventing boiling during summer use. 3. Scale removal: Premium coolants are made with distilled water and contain anti-scaling additives, which not only prevent scale buildup but also help remove existing scale.
When the Mercedes-Benz displays a low coolant warning, I strongly advise against continuing to drive. Coolant is a critical component for protecting the engine, as it prevents overheating and freezing. If the fluid level is too low, the engine temperature can rise sharply, potentially causing cylinder head deformation, piston seizure, or even complete engine failure, with repair costs often exceeding tens of thousands of yuan. It is best to pull over immediately, open the hood, and check the coolant reservoir level. If the level is low, add distilled water as an emergency measure, but remember this is only a temporary solution. If you notice a leak, you must wait for a tow truck to avoid causing more severe damage. Safe driving should always be the top priority—don’t risk major damage to save a little time.
