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.

Where is the fuel filler flap button on Volkswagen cars?

Volkswagen models have different locations for the fuel filler flap button. Some are located under the handle on the left door panel, while others can be opened by simply pressing the fuel filler flap directly when the vehicle is unlocked. After refueling, just press it back into place. Below are different methods for opening the fuel filler flap: 1. In-car switch type: Nowadays, it is more common to have a switch button inside the car, which is more convenient compared to the mechanical key method. This method has been widely used in fuel vehicles for a long time. However, it can also lead to refueling without turning off the engine, so owners need to be extra careful. Similar to the in-car switch is the in-car lever, which is usually located in the same position as the trunk lever, typically on the left side of the driver's seat. 2. Mechanical key type: Generally, the ways to open the fuel filler flap in household cars include using a key, an in-car switch, or simply pressing it directly. The mechanical key method is relatively more complicated. 3. Direct press type: The direct press method for opening the fuel filler flap is the most convenient, requiring no action from the owner, as the fuel attendant can refuel directly. For vehicles with this type of fuel filler flap, owners must ensure the car is locked when parked; otherwise, the fuel filler flap can be opened if the central locking is not engaged, posing a certain risk.
