shall also provide the driver with the warning specified in paragraph 5.4.2. below when tested in accordance with the provisions of paragraph 6.6. below (failure detection test). The signal shall be constant.

              5.2.3. The LDWS shall be active at least at vehicle speeds above 60 km/h, unless manually deactivated as per paragraph 5.3. below.

              5.3. If a vehicle is equipped with a means to deactivate the LDWS function, the following conditions shall apply as appropriate:

              5.3.1.  The LDWS function shall be automatically reinstated at the initiation of each new ignition "on" (run) cycle.

              5.3.2.  A constant optical warning signal shall inform the driver that the LDWS function has been deactivated. The yellow warning signal specified in paragraph 5.4.2. below may be used for this purpose.

              5.4. Warning indication

              5.4.1. The lane departure warning referred to in paragraph 5.2.1. above shall be noticeable by the driver and be provided by:

 (a) At least two warning means out of optical, acoustic and haptic, or
 (b) One warning means out of haptic and acoustic, with spatial indication about the direction of unintended drift of the vehicle.
              5.4.1.1 Where an optical signal is used for the lane departure warning, it may use the failure warning signal as specified in paragraph 5.4.2. below in a flashing mode.

              5.4.2. The failure warning referred to in paragraph 5.2.2. above shall be a yellow optical warning signal.

              5.4.3. The LDWS optical warning signals 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.

              5.4.4. 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.

              5.4.5. When the driver is provided with an optical warning signal to indicate that the LDWS is temporarily not available, for example due to inclement weather conditions, the signal shall be constant. The failure warning signal specified in paragraph 5.4.2. above may be used for this purpose.

              5.5. Provisions for the periodic technical inspection

              5.5.1. At a periodic technical inspection it shall be possible to confirm the correct operational status of the LDWS by a visible observation of the failure warning signal status, following a "power-ON" (off–system OK, on–system 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
