Traction control / stability light

Also called: ESC light, ESP light, car with squiggly lines, traction light

Safe to monitor

Flashing while driving on a slippery road is normal. If it stays on, drive gently and have it checked.

What it means

A flashing light means the system is working right now to stop the wheels from spinning or sliding. A steady light means the system is switched off or has a fault.

Step by step

  1. If it flashes, ease off the accelerator: the road is slippery.
  2. If it stays on, check you have not switched the system off with its button.
  3. If it stays on after a restart, have it checked; it often shares a fault with the ABS.

Can I keep driving?

Yes. Take extra care in wet or icy conditions.

What the colours mean

Amber light: something needs checking soon.

Symbols and colours vary between makes and models. Your owner's manual has the exact list for your car. General information only. Every car is different: check your owner's manual, and if anything involves brakes, steering, tires or a burning smell, have a qualified mechanic look at it before you drive on.
