What does the small yellow light on the left side of the car dashboard mean?

[Reese]

The yellow light on the left side of the car dashboard is a reminder to the driver that the vehicle is low on antifreeze. Solution: There is a water level sensor in the small reservoir of the radiator. When it detects that the antifreeze in the small reservoir is low, this warning light will appear on the car dashboard. The solution is to simply add antifreeze. If a light comes on in a Volkswagen, it may indicate one of the following issues: Engine oil indicator: This light displays the oil pressure status in the engine. It lights up when the ignition is turned on during the vehicle's self-check and turns off after the engine starts. If the light remains on, it means the engine oil pressure is below the specified limit and requires repair. Handbrake indicator: A common mistake made by beginners is driving with the handbrake engaged. This indicator is a circle with an exclamation mark or the letter P and is usually off. It lights up when the handbrake is engaged. Currently, only some models have a warning sound for driving with the handbrake on.
