When the SVS light in a car illuminates, it indicates an engine malfunction. Normally, the SVS light turns on when the ignition key is switched on and goes off after the vehicle starts. If the SVS light comes on while driving, it means there is an issue with the vehicle's engine. Below are solutions for the SVS light: When the powertrain self-diagnosis detects an abnormality: It will use the SVS light to alert the user to inspect and repair the vehicle. Possible sources of the SVS light warning: Engine, transmission, or gear shift mechanism. If the SVS indicator remains lit, it means the engine control unit has detected incorrect signals from various sensors or that they are operating outside standard parameters. In such cases, diagnostic tools should be used for inspection and repair, and prolonged driving is not recommended. If the SVS light turns off later: Frozen data can be used for fault analysis, and it is advisable to visit a repair shop for inspection or repair.

When I saw the SVS light come on, I immediately knew something was wrong. This usually means the car is telling me there's an issue with some system, possibly the engine, transmission, or other electronic components. The first thing I did was stay calm, avoid pressing the accelerator too hard, then slow down and safely pull over to the roadside or a parking lot. I quickly turned off the engine and restarted it to see if the light would go away. If it stays on, I might check if the engine oil or transmission fluid is low, as this can sometimes trigger the warning. But don't force the car to keep driving, or you might damage more parts. Last time I encountered this situation, I had it towed to a repair shop, and they said it was a sensor false alarm—just needed cleaning. In short, safety first. It's best to take the car to a professional repair shop to diagnose the trouble codes and identify the specific problem.

Should You Press the Brake When Starting the Engine?

For automatic transmission vehicles, you need to press the brake when starting the engine. For manual transmission vehicles, you should press the clutch to start. Some manual cars can be started directly by turning the key without pressing the brake or clutch if they are in neutral. Benefits of pressing the brake when starting: 1. Enhanced braking: Pressing the brake helps improve the vehicle's braking capability. Some parking slopes are too steep, requiring the use of the handbrake + gear method. If you press the clutch when starting, the car might roll due to insufficient handbrake effectiveness. Pressing the brake at this moment can prevent rolling. 2. Preventing accidents: It avoids situations where you forget to park in gear and start without pressing the clutch, which could cause the car to lurch forward and lead to an accident. Pressing the brake when starting in gear can instantly stall the engine, preventing accidents.
