in which the collision warning signals are presented to the driver shall be provided by the vehicle manufacturer at the time of type-approval and recorded in the test report.

              5.5.3. Where an optical means is used as part of the collision warning, the optical signal may be the flashing of the failure warning signal specified in paragraph 5.5.4. below.

              5.5.4. The failure warning referred to in paragraph 5.2.1.2. above shall be a constant yellow optical warning signal.

              5.5.5. Each AEBS optical warning signal shall be activated either when the ignition (start) switch is turned to the "on" (run) position or when the ignition (start) switch is in a position between the "on" (run) and "start" that is designated by the manufacturer as a check position (initial system (power-on)). This requirement does not apply to warning signals shown in a common space.

              5.5.6. The optical warning signals shall be visible even by daylight; the satisfactory condition of the signals must be easily verifiable by the driver from the driver's seat.

              5.5.7. When the driver is provided with an optical warning signal to indicate that the AEBS is temporarily not available, for example due to inclement weather conditions, the signal shall be constant and yellow in colour. The failure warning signal specified in paragraph 5.5.4. above may be used for this purpose.

              5.6. Provisions for the periodic technical inspection

              5.6.1. At a periodic technical inspection it shall be possible to confirm the correct operational status of the AEBS by a visible observation of the failure warning signal status, following a "power-ON" and any bulb check.

               In the case of the failure warning signal being in a common space, the common space must be observed to be functional prior to the failure warning signal status check.

              5.6.2. At the time of type approval, the means to protect against simple unauthorized modification of the operation of the failure warning signal chosen by the manufacturer shall be confidentially outlined.

               Alternatively, this protection requirement is fulfilled when a secondary means of checking the correct operational status of the AEBS is available.

              6.  Test procedure
              6.1. Test conditions

              6.1.1. The test shall be performed on a flat, dry concrete or asphalt surface affording good adhesion.

              6.1.2. The ambient temperature shall be between 0 °C and 45 °C.

              6.1.3. The horizontal visibility range shall allow the target to be observed throughout the test.

              6.1.4 The tests shall be performed when there is no wind liable to affect the results.

              6.2. Vehicle conditions

              6.2.1. Test weight

               The vehicle shall be tested in a condition of load to be agreed between the manufacturer and the Technical Service. No alteration shall be made once the test procedure has begun.

       6.3.  Test
