CAUTION:
- Carbon may adhere to the tip of the spark plug during vehicle delivery or repeated short distance driving during the winter time. If there is any malfunction such as rough idling or start difficulty due to carbon adhesion causing plug fouling, burn off the carbon by performing no-load racing of the engine.
- When performing the no-load racing, apply the side brake and foot brake, move the selector lever to P position to prevent an accident and serious injury.
