Maintenance 111 Checking and Draining Oil Check the oil level through the top plug 1. The oil should be level with the hole. Add oil if necessary. Drain oil through the bottom plug 2. Oil should be drained immediately after driving while it is still hot. WARNING Hot oil can cause severe burns. DO NOT allow hot oil to contact the skin. When changing oil, wear protective gloves.
