1. Check engine oil level.
   
   

   1. Warm up the engine, stop the engine and wait 5 minutes. The oil level should be between the dipstick's low level mark and full level mark.
      If low, check for leakage and add oil up to the full level mark.
      

      NOTICE:

      Do not fill engine oil above the full level mark.

2. Check engine oil quality.
   
   

   1. Check the oil for deterioration, water contamination, discoloration and thinning.
      If the quality is visibly poor, replace the oil.
