              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 targets

              6.3.1. The target used for the tests shall be a regular high volume series production passenger car of category M1 AA saloon, or alternatively a "soft target" representative of such a vehicle in terms of its identification characteristics applicable to the sensor system of the AEBS under test.[4]

              6.3.2. Details that enable the target(s) to be specifically identified and reproduced shall be recorded in the vehicle type approval documentation.

              6.4. Warning and activation test with a stationary target

              6.4.1. The subject vehicle shall approach the stationary target in a straight line for at least two seconds prior to the functional part of the test with a subject vehicle to target centreline offset of not more than 0.5 m.

               The functional part of the test shall start when the subject vehicle is travelling at a speed of 80 ± 2 km/h and is at a distance of at least 120 m from the target.

               From the start of the functional part until the point of collision there shall be no adjustment to any control of the subject vehicle by the driver other than slight adjustments to the steering control to counteract any drifting.

              6.4.2. The timing for the collision warning modes referred to in paragraph 5.5.1. above shall comply with the following:

              6.4.2.1. At least one warning mode shall be provided no later than specified in Table I, Column B, of Annex 3.

              In the case of the vehicles referred to in Table I, row 1, of Annex 3, the warning shall be haptic or acoustic.

              In the case of the vehicles referred to in Table I, row 2, of Annex 3, the warning shall be haptic, acoustic or optical

              6.4.2.2.  At least two warning modes shall be provided no later than specified in Table I, Column C, of Annex 3.

              6.4.2.3. Any speed reduction during the warning phase, shall not exceed either 15 km/h or 30 per cent of the total subject vehicle speed reduction, whichever is higher.

              6.4.3. The collision warning phase shall be followed by the emergency braking phase.

              6.4.4. The total speed reduction of the subject vehicle at the time of the impact with the stationary target shall be not less than the value specified in Table I, column D of Annex 3.

              6.4.5. The emergency braking phase shall not start before a TTC equal to or less than 3.0 seconds.

              Compliance shall be verified by either actual measurement during the test or using documentation provided
