Maintenance and care 4. Locate and carefully remove the engine oil dipstick. 5. Wipe the dipstick clean. Insert the dipstick fully, then remove it again. The oil level should be in the range shown on the dipstick. 6. If the oil level is below the minimum line, add engine oil as necessary. If the oil level is beyond the maximum line, engine damage or high oil consumption may occur and some oil must be removed from the engine by a service technician. 7. Put the dipstick back in and ensure it is fully seated. Adding engine oil 1. Check the engine oil. For instructions, refer to Checking the engine oil in this chapter. 2. If the fluid level is not within the normal range, add only certified engine oil of the preferred viscosity. Add engine oil through the oil filler cap. Remove the filler cap and use a funnel to pour oil in the opening. 3. Recheck the oil level. Make sure the oil level is not above the full mark on the dipstick. Continuous contact with used motor oil has caused cancer in laboratory mice. ADD FULL 161
