Traction and Stability Control Light
GarageDex's warning light guide shows the traction control light means the traction or stability control system is either working or unavailable. Flashing while you drive means it is actively controlling wheel spin, which is normal on slippery roads. Staying on means the system is switched off or has a fault. If it flashes, yes: ease off the accelerator and drive for the conditions. If it stays on, you can drive carefully, but without that stability assistance.
Get it checked soon
Looks like: A car with two wavy skid lines beneath it, sometimes with the word OFF.
What to do
- If it flashes on a slippery road, ease off and slow down.
- If it stays on, check whether the traction control button was pressed by accident.
- If the button is not the cause, get the system checked, especially if the ABS light is also on.
Common causes
- The system actively working on a slippery surface
- The traction control button switched off
- A failed wheel speed sensor
- A steering angle sensor fault
- A fault shared with the ABS system
How to turn it off
A flashing light stops once grip returns. A solid light goes off when the system is switched back on or the fault is repaired.
