1. Warm up the engine, stop it and wait 5 minutes. The oil level should be between the dipstick's low level mark and full level mark.

   If the oil level is low, check for leakage and add oil up to the full level mark.

   NOTE: Do not fill above the full level mark.

1. Check the oil for deterioration, water contamination, discoloring or thinning.

   If the quality is visibly poor, replace the oil.

   Oil grade: 

   Use ILSAC multigrade engine oil. SAE 5W-30 engine oil may be used. However, SAE 5W-30 is the best choice for good fuel economy and good starting in cold weather. 

1. Disconnect the oil pressure switch connector.
2. Using a 24 mm deep socket wrench, remove the oil pressure switch.
