Draining and filling in engine oil
NOTICE
Incorrect oil level
- Risk of damage to engine or catalytic converter
-> Check the oil level regularly.
-> The oil level must not fall below the Minimum marking or rise above the Maximum marking.
-> Only use approved engine oils.
WARNING
Hot fluid
- Danger of scalding
-> Avoid contact with hot fluid.
-> Wear personal protective gear.
Information
- The tightening specifications for the basic engine are stored centrally. -> 1001IN Tightening torques, tightening sequences, assembly overviews [1][2]Specifications. Tightening torques and assembly instructions for other assemblies (e.g. chassis, electrics, transmission or body) or for peripheral engine equipment can be found in the corresponding documents.
Information
When changing engine oil, drain the oil when it is hot because hot oil is more fluid than cold oil and all dirt particles and suspended matter can be cleaned out. Position the collecting container as close as possible to the drain outlet of the oil pan.
1. Remove oil drain plug -arrow- and collect the engine oil in a collecting container (allow to drain for approx. 5 minutes). Dispose of waste oil in accordance with legal requirements.
Oil drain plug
2. Replace sealing ring on oil drain plug and fit oil drain plug.
3. Fill in engine oil of the stipulated viscosity and quality. Oil filling capacity without oil filter => Filling capacity: 8.5 liters; oil filling capacity with oil filter => Filling capacity: 9.0 liters

6. First fit the filter element into the oil guide housing.
7. Lightly oil the sealing ring for the oil filter cover with engine oil. Screw in the oil filter cover and tighten hand-tight using a suitable ring wrench. For details of final tightening, see -> 1001IN Tightening torques, tightening sequences, assembly overviews for engine [1][2]Specifications.
8. Fill in engine oil. The oil filling capacity after removing the oil filter is => Filling capacity: 0.5 liters.
Checking engine-oil level
NOTICE
Incorrect oil level
- Risk of damage to engine or catalytic converter
-> Check the oil level regularly.
-> The oil level must not fall below the Minimum marking or rise above the Maximum marking.
-> Only use approved engine oils.
Information
Requirements for oil level measurement using the instrument cluster:
- Vehicle must be standing horizontally
- Oil temperature 80°. 100°
- Engine off
- Ignition on
- Wait two minutes after opening the engine compartment lid
1. Select the Oil level function in the multi-function display.
1.1. Select Vehicle in the main menu, then select Oil level and confirm your selection.
2. Check the engine-oil level on the segment display and top up engine oil if necessary.
2.1. The segment display is green if the engine-oil level is between the Min and Max markings.
- Maximum engine-oil level => Maximum engine-oil level , segments are green.
Maximum engine-oil level
- Minimum engine-oil level => Minimum engine-oil level , lowest segment is yellow.
Minimum engine-oil level
- Engine-oil level too low => Engine-oil level too low , lowest segment is red.
Engine-oil level too low
- Engine-oil level too high => Engine-oil level too high , all segments are red.
Engine-oil level too high
3. Refill quantity:
- The difference between the Min and Max markings is approx. 1 litre
- One segment of the display corresponds to approx. 0.25 liters
