fault present).

               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.

              5.5.2. 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 LDWS is available.

6. Test procedure
              6.1. The manufacturer shall provide a brief documentation package which gives access to the basic design of the system and, if applicable, the means by which it is linked to other vehicle systems. The function of the system shall be explained and the documentation shall describe how the operational status of the system is checked, whether there is an influence on other vehicle systems, and the method(s) used in establishing the situations which will result in a failure warning signal being displayed.

              6.2. Test conditions

              6.2.1. The test shall be performed on a flat, dry asphalt or concrete surface.

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

              6.2.3. Visible lane markings

              6.2.3.1. The visible lane markings used in the lane departure warning tests of paragraph 6.5. below shall be those of one of the Contracting Parties as identified in Annex 3 to this Regulation, with the markings being in good
              condition and of a material conforming to the standard for visible lane markings of that Contracting Party. The visible lane marking layout used for the testing shall be recorded.

              6.2.3.2. The vehicle manufacturer shall demonstrate, through the use of documentation, compliance with all the other lane markings identified in Annex 3 to this Regulation. Any such documentation shall be appended to the test report.

              6.2.3.3. In the case the vehicle type may be equipped with different variants of the LDWS with regional specific adjustments; the manufacturer shall demonstrate through documentation that the requirements of this Regulation are fulfilled in all variants.

              6.2.4. The test shall be performed under visibility conditions that allow safe driving at the required test speed.

              6.3. Vehicle conditions

              6.3.1. Test weight

               The vehicle may be tested at any condition of load, the distribution of the mass among the axles being that stated by the vehicle manufacturer without exceeding any of the maximum permissible mass for each axle. No alteration shall be made once the test procedure has begun. The vehicle manufacturer shall demonstrate through the use of documentation that the system works at all conditions of load.

              6.3.2. The vehicle shall be tested at the tyre pressures recommended by the vehicle manufacturer.

              6.3.3. In the case
