       3.6. ESC OFF tell-tale

        If the manufacturer elects to install a control to turn off or reduce the performance of the ESC system under paragraph 3.5., the tell-tale requirements of paragraphs 3.6.1. to 3.6.4. shall be met in order to alert the driver to the inhibited or reduced state of ESC system functionality.  This requirement does not apply for the driver-selected mode referred to in paragraph 3.5.1.2.

       3.6.1. The vehicle manufacturer shall provide a tell-tale indicating that the vehicle has been put into a mode that renders it unable to satisfy the requirements of paragraphs 3., 3.1., 3.2. and 3.3., if such a mode is provided.

       3.6.2.3. Shall be identified by the symbol shown for "ESC Off" below or the text "ESC OFF",

       3.6.2.4. Shall be yellow or amber in colour;

       3.6.2.5. When illuminated, shall be sufficiently bright to be visible to the driver under both daylight and night time driving conditions, when the driver has adapted to the ambient roadway light conditions;

       3.6.2.6. Shall remain continuously illuminated for as long as the ESC is in a mode that renders it unable to satisfy the requirements of paragraphs 3., 3.1., 3.2. and 3.3;

       3.6.2.7. Except as provided in paragraphs 3.6.3. and 3.6.4. each "ESC Off" tell-tale shall be activated as a check of lamp function either when the ignition locking system is turned to the "On" ("Run") position when the engine is not running, or when the ignition locking system is in
