・ Precautions for restarting after the overheat prevention device is
actuated
1. Resolve the cause of the abnormally high cooling water temperature,
and then restart the engine. If the cause of the abnormally high cooling
water temperature has not been resolved, the engine will stop again
within approximately 30 seconds.
(The time in seconds until engine stop varies depending on the
temperature of the cooling water.)
2. The Starter motor rotates when the cooling water temperature exceeds
approximately 120 C, but the engine prevention function is actuated
and the pump cannot be restarted.
