a check position;

       3.4.1.8. Shall extinguish at the next ignition cycle after the malfunction has been corrected in accordance with paragraph 5.10.4.;

       3.4.1.9. May also be used to indicate the malfunction of related systems/functions, including traction control, trailer stability assist, corner brake control, and other similar functions that use throttle and/or individual torque control to operate and share common components with ESC.

       3.4.2. The ESC malfunction tell-tale need not be activated when a starter interlock is in operation.

       3.4.3. The requirement of paragraph 3.4.1.7. does not apply to tell-tales shown in a common space.

       3.4.4. The manufacturer may use the ESC malfunction tell-tale in a flashing mode to indicate ESC operation.

       3.5. ESC Off and other system controls

        The manufacturer may include an "ESC Off" control, which shall be illuminated when the vehicle's headlamps are activated, and which has a purpose to place the ESC system in a mode in which it will no longer satisfy the performance requirements of paragraphs 3., 3.1., 3.2. and 3.3.  Manufacturers may also provide controls for other systems that have an ancillary effect upon ESC operation.  Controls of either kind that place the ESC system in a mode in which it may no longer satisfy the performance requirements of paragraphs 3., 3.1., 3.2. and 3.3. are permitted, provided that the system also meets the requirements of paragraphs 3.5.1., 3.5.2. and 3.5.3.

       3.5.1. The vehicle's ESC system shall always return to the manufacturer's original default mode that satisfies the requirements of paragraphs 2. and 3. at the initiation of each new ignition cycle, regardless of what mode the driver had previously selected.  However, the vehicle's ESC system need not return to a mode that satisfies the requirements of paragraphs 3. through 3.3. at the initiation of each new ignition cycle if:

       3.5.1.1. The vehicle is in a four-wheel drive configuration which has the effect of locking the drive gears at the front and rear axles together and providing an additional gear reduction between the engine speed and vehicle speed of at least 1.6, selected by the driver for low-speed, off-road driving; or

       3.5.1.2. The vehicle is in a four-wheel drive configuration selected by the driver that is designed for operation at higher speeds on snow-, sand-, or dirt-packed roads and that has the effect of locking the drive gears at the front and rear axles together, provided that in this mode the vehicle meets the stability performance requirements of paragraphs 3.1. and 3.2. under the test conditions specified in paragraph 4.  However, if the system has more than one ESC mode that satisfies the requirements of paragraphs 3.1. and 3.2. within the drive configuration selected for the previous ignition cycle, the ESC shall return to
