Adding engine oil
Too much or incorrect engine oil can cause engine damage! For this reason:
• Do not add engine oil above the MAX mark of oil dipstick 269/A
• Use only the specified engine oil
Use a suitable container to collect the engine oil as it drains and dispose of it in
an environmentally friendly manner!
Adding the engine oil too fast via filler inlet B in the valve cover can cause
engine damage.
• Add the engine oil slowly so it can go down without entering the intake system.
☞ Proceed as follows:
•Clean the area around oil filler cap B (Tier III) or C (Tier IV) with a lint-free cloth
•Open filler cap B (Tier III) or C (Tier IV)
•Raise oil dipstick A slightly to allow any trapped air to escape
•Add engine oil
•Wait about 3 minutes until all the oil has run into the oil sump
•Check the oil level
– see Checking the oil level on page 5-5
•Add oil if necessary and check the oil level again
•Close filler cap B (Tier III) or C (Tier IV)
•Push oil dipstick A back in as far as possible
•Completely remove all oil spills from the engine
