- While the conditions in the list are satisfied, race the engine at the speed of approx. 2, 500 rpm for 40 seconds or more.
- Start the vehicle, then accelerate the vehicle to 50 km/h (31.1 MPH) or more.
- When the speed reaches 50 km/h (31.1 MPH) or more, release the accelerator pedal, the brake pedal and the clutch pedal (MT model) to decelerate the vehicle without shifting the gear. At this time, select an appropriate gear beforehand so that the engine speed can decrease from 2, 500 rpm to 1, 900 rpm for 5 seconds or more.NOTE:
- The vehicle speed does not matter so long as the engine speed can maintain from 2, 500 rpm to 1, 900 rpm for 5 seconds or more. Example: On a downhill grade, it can be performed with a low speed gear and at a low vehicle speed.
- When it is performed with the electrical load such as the air conditioner, etc. turned OFF or the vehicle driven on a downhill grade, the engine speed decreases slowly. Therefore, the continuous time can be maintained easily.
