that prevents the requirements of this Regulation of being met. The warning shall be as specified in paragraph 5.5.4.

              5.1.4.1.1. There shall not be an appreciable time interval between each AEBS self-check, and subsequently there shall not be a delay in illuminating the warning signal, in the case of an electrically detectable failure.

              5.1.4.1.2. If the system has not been initialised after a cumulative driving time of 15 seconds above a speed of 10km/h, information of this status shall be indicated to the driver. This information shall exist until the system has been successfully initialised.

              5.1.4.2. A deactivation warning, if the vehicle is equipped with a means to deactivate the AEBS, shall be given when the system is deactivated. This shall be as specified in paragraph 5.4.3.

              5.1.4.3. Upon detection of any non-electrical failure condition (e.g. sensor blindness or sensor misalignment), the warning signal as defined in paragraph 5.1.4.1. shall be illuminated.

              5.1.5. Emergency braking

              Subject to the provisions of paragraphs 5.3.1. and 5.3.2., the system shall provide emergency braking interventions described in paragraphs 5.2.1.2. and 5.2.2.2. having the purpose of significantly decreasing the speed of the subject vehicle.

              5.1.6. False reaction avoidance

              The system shall be designed to minimise the generation of collision warning signals and to avoid advanced emergency braking in situations where the driver would not recognise an impending collision. This shall be demonstrated in the assessment carried out under Annex 3, and this assessment shall include in particular scenarios listed in Appendix 2 of Annex 3.

              5.1.7. Any vehicle fitted with an AEBS shall meet the performance requirements of UN Regulation No. 13-H in its 01 series of amendments for vehicles of Category M1 and N1 or Regulation No. 13 in its 11 series of amendments for vehicles of Category N1 and shall be equipped with an anti-lock braking function in accordance with the performance requirements of Annex 6 to UN Regulation No.13-H in its 01 series of amendments or of Annex 13 to UN Regulation No. 13 in its 11 series of amendments.

              5.2.  Specific Requirements

              5.2.1. Car to car scenario

              5.2.1.1.  Collision warning

              When a collision with a preceding vehicle of Category M1, in the same lane with a relative speed above that speed up to which the subject vehicle is able to avoid the collision, is imminent, a collision warning shall be provided as specified in paragraph 5.5.1., and shall be triggered at the latest 0.8 seconds before the start of emergency braking.

              However, in case the collision cannot be anticipated in time to give a collision warning 0.8 seconds ahead of an emergency braking a collision warning shall be provided as specified in paragraph 5.5.1. and shall be provided no later than
