ถ้าเป็นวอลโว่ที่มีระบบ Emergency Brake Light (EBL), ไฟเบรคจะกระพริบช่วงแรกตอนเบรคสุดๆ แล้วไฟฉุกเฉินจะกระพริบแทนตอนหลัง รายละเอียดตามข้างล่างครับ (จากmanual)
Emergency brake light and automatic hazard warning flashers*
Emergency brake lights (Adaptive Brake Lights) are activated in the event of sudden braking or if the ABS brakes are activated. This function means that the brake light flashes to immediately alert cars travelling behind.
The system is activated if ABS is used for more than 0.5 seconds or in the event of heavy braking, however, only when braking from speeds above 50 km/h. When the speed of the car is lower than 30 km/h the brake lights shine normally again and the hazard warning flashers are switched on automatically. The hazard warning flashers remain on until the car accelerates again but can be deactivated with the button for hazard warning flashers
