Amber light
ABS Warning Light
The anti-lock braking system has a fault and is switched off. Normal brakes still work.
High risk
Brakes work, but wheels can lock in an emergency stop. Keep extra distance and have it checked soon. If the red brake light is on too, stop.
Short answer · Can I drive with the ABS light on?
Yes, carefully: the normal brakes still work, but the wheels can lock during hard braking, especially on wet or slippery roads, so keep more distance. Stability control is usually switched off at the same time. If the red brake warning also lights up, brake force distribution may be affected: stop and have the car checked.

- Keep more distanceWithout ABS the wheels can lock under hard braking.
- Check the red brake lightBoth lights together need immediate attention.Brake force distribution may not work.
