the ignition to the "On" ("Run") position or, where applicable, the appropriate position for the lamp check. The ESC malfunction tell-tale shall be illuminated as a check of lamp function, as specified in paragraph 7.4.1.3., and if equipped, the "ESC Off" tell-tale shall also be illuminated as a check of lamp function, as specified in paragraph 7.6.2.3. The tell-tale bulb check is not required for a tell-tale shown in a common space as specified in paragraphs 7.4.3. and 7.6.4.
9.3. "ESC Off" control check. For vehicles equipped with an "ESC Off" control, with the vehicle stationary and the ignition locking system in the "Lock" or "Off" position, switch the ignition locking system to the "On" ("Run") position. Activate the "ESC Off" control and verify that the "ESC Off" tell-tale is illuminated, as specified in paragraph 7.6.2. Turn the ignition locking system to the "Lock" or "Off" position. Again, switch the ignition locking system to the "On" ("Run") position and verify that the "ESC Off" tell-tale has extinguished indicating that the ESC system has been restored as specified in paragraph 7.5.1.
9.4. Brake conditioning
 Condition the vehicle brakes in the manner described in paragraphs 9.4.1. to 9.4.4.
9.4.1. Ten stops are performed from a speed of 56 km/h, with an average deceleration of approximately 0.5g.
9.4.2. Immediately following the series of ten 56 km/h stops, three additional stops are performed from 72 km/h at higher deceleration.
9.4.3. When executing the stops in paragraph 9.4.2., sufficient force is applied to the brake pedal to bring the vehicle's antilock braking system (ABS) into operation for a majority of each braking event.
9.4.4. Following completion of the final stop in 9.4.2., the vehicle is driven at a speed of 72 km/h for five minutes to cool the brakes.
9.5. Tyre Conditioning
 Condition the tyres using the procedure of paragraphs 9.5.1. to 9.5.3. to wear away mould sheen and achieve operating temperature immediately before beginning the test runs of paragraphs 9.6. and 9.9.
9.5.1. The test vehicle is driven around a circle 30 meters in diameter at a speed that produces a lateral acceleration of approximately 0.5 to 0.6g for three clockwise laps followed by three anticlockwise laps.
9.5.2. Using a sinusoidal steering pattern at a frequency of 1 Hz, a peak steering wheel angle amplitude corresponding to a peak lateral acceleration of 0.5 to 0.6g, and a vehicle speed of 56 km/h, the vehicle is driven through four passes performing 10 cycles of sinusoidal steering during each pass.
9.5.3. The steering wheel angle amplitude of the final cycle of the final pass shall be twice that of the other cycles. The maximum time permitted between each of the laps and passes is five minutes.
