The Emergency Stop Signal system warns the driver behind by flashing the brake lights when the vehicle brakes suddenly and hard.

The system is activated when:

  • The vehicle stops suddenly. (The braking force exceeds 7 m/s² and the vehicle speed exceeds 55 km/h.)
  • The ABS is activated and the vehicle speed exceeds 34 mph (55 km/h).

The hazard warning lights automatically turn on after the brake lights flash:

  • When the vehicle speed is below 40 km/h,
  • When the ABS is turned off and
  • The hazard warning lights turn off when the sudden braking situation ends:
  • When the vehicle travels at low speed for a certain period of time. The driver can manually turn off the hazard warning lights by pressing the button.
