On many modern cars, its instrument cluster is a host to a lot of lights. Of course, there’s the backlight for the gauges, but then there are the many pilot lights for your car’s numerous features and parts. This of course includes the dreaded check engine light.

These take on shapes that serve as a hint as to what they represent. Sometimes however, newer car owners will get confused by these symbols. Take for example the symbol of a car with wavy or squiggly lines behind it. So, what does this particular symbol mean?
Car with squiggly lines symbol: What does it mean?
When a symbol with a car with wavy or squiggly lines behind it lights, it means that your car has activated its stability control feature. In some cars, the light flashes whenever the said feature is doing its job. In others, the said symbol has the words “off” written below it. If that’s the case, then it means that the stability control system is deactivated.

In cars where you can toggle the stability control system on and off, its button usually features the same car with squiggly lines symbol. Conversely, if you’re sure that you didn’t turn it off, but the light comes on, there might be something wrong with the said system. If this happens, we urge you to take it to your car brand’s nearest casa and have it fixed.
But what is stability control?
A car’s stability control system applies the brakes to help direct the car and/or to help the driver maintain control. Whenever it detects that there is a loss of traction or loss of steering control, the system as directed by the car’s computer applies the appropriate amount of braking.
To this end, it also helps to counter the effects of oversteer and understeer.
To do this, modern cars with stability control communicate with the anti-lock braking system’s yaw control rate. It can also slow down a car’s individual wheels, and can sense wheel slip loss of traction by way of sensors.
This feature is particularly useful on road conditiongs like these
In more modern cars, stability control is often done through minute and fast adjustments. This allows the stability control to perform changes in the blink of an eye.
In some road conditions, stability control is a must-have safety feature for some drivers. Wet roads, muddy roads, sandy roads, among others can rob a car of control. As such, this system is one of the few things that’s preventing you from spinning out, or worse, crashing.
In some models, the stability control can be toggled with a button
For some more advanced stability control systems, these can even actively override the car’s anti-lock braking system and lock the wheels whenever the brakes are applied.
This way, the tires can provide constant grip. This capability varies to some degree depending on niche car models, but are common on cars with four-wheel-drive systems. It can even communicate with the car’s differential lock and adjust accordingly to provide better grip.
