Vehicle Roll Prevention Function (Automatic transaxle)
Vehicles with the i-stop function are equipped with a vehicle roll prevention function. This
function prevents the vehicle from rolling, such as when releasing the brake pedal while on
a slope under the following conditions:
While engine idling is stopped (prevents the vehicle from rolling back)
When the engine restarts after releasing the brake pedal (prevents the vehicle's sudden
movement due to vehicle creep), sudden movement of the vehicle is prevented by
controlling the brakes or the automatic transaxle.
