Caution: Never continue driving when this light is on.

3. Coolant Temperature Warning Light

This light is easily recognizable with its thermometer-in-water symbol. It illuminates when the engine coolant temperature is too high, possibly due to low coolant levels, a malfunctioning fan, or a clogged radiator.

A Driver’s Hard-Earned Lesson:

“I was transporting goods from Hanoi to Hai Phong when the coolant temperature warning light suddenly came on. I stopped to check and found a coolant leak. Luckily, I caught it in time, otherwise, the engine would have failed on the road,” shared Mr. Nguyen Van B, a seasoned truck driver.

4. Brake System Warning Light

This light is typically a circle with an exclamation point (!) inside or the word “BRAKE.” It can illuminate when the parking brake is engaged or if there’s an issue with the braking system, such as low brake fluid.

Remember: Your braking system is your safety net. Never ignore any unusual signs from this warning light.

5. Tire Pressure Monitoring System (TPMS) Warning Light

This light resembles a tire cross-section with an exclamation point (!) in the center. When illuminated, it indicates that one or more of your tires are significantly underinflated or overinflated.

Helpful Tip: Regularly check your tire pressure, especially before long trips.

6. Battery Warning Light

This light is symbolized by a battery icon. When illuminated, it indicates a problem with the battery charging or the vehicle’s electrical system.
